EXECUTIVE SUMMARY

This report identifies emission units and emissions to the atmosphere associated with the Shell 

Gulf of Mexico Inc. (Shell) exploration drilling program at Outer Continental Shelf (OCS) lease

blocks at the Burger Prospect in the Chukchi Sea. This document has been prepared to assist

the Bureau of Ocean Energy Management (BOEM) in the assessment and authorization of air 

emissions attributable to Shell’s exploration drilling operations. This document presents the 

following two emission inventories. 

1. For purposes of demonstrating applicability under the BOEM Air Quality Regulatory 

Program (AQRP) (30 CFR Part 550, Subpart C), Shell provides an AQRP emission

inventory. As required by 30 CFR 550.218(a)(3), the inventory is estimated based on the 

projected emissions of the maximum rated capacity of the equipment on the proposed 

drilling unit under its physical and operational design. 

2. For purposes of demonstrating impacts under the National Environmental Policy Act 

(NEPA), Shell provides a NEPA emission inventory. This inventory provides an 

estimate of expected emissions in geographic areas of interest. 

This document describes the types of activities and locations that would result in onshore and 

offshore air emissions associated with Shell’s exploration drilling program as described in the

Shell Revised Outer Continental Shelf Lease Exploration Plan, Chukchi Sea, Alaska, Revision 2

(EP Revision 2). The emission inventories described herein adopt a number of conservative 

assumptions that result in an overestimate of the actual onshore and offshore emissions 

associated with the EP Revision 2. Actual activities and locations may vary but are expected to 

contribute to lower increases in air emission impacts. In particular, the following conservative 

assumptions have been adopted:

• Annual emissions from the drilling units are based on continuous operation of engines, 

boilers, and incinerators for 24 hours per day (at 80 percent load for the engines; 100 

percent load for boilers and incinerators) for the entire 120-day season (2,880 hours per 

season), even though that is a significant overestimate of their use.

• Annual emissions from certain engines, boilers, and incinerators on a number of support 

vessels are based on continuous operation 24 hours per day for the entire 120-day season 

(2,880 hours per season), even though that is a significant overestimate of their use.

• Annual emissions from emergency generator engines, lifeboat engines, rescue crafts, and 

seldom-used engines on support vessels are based on an assumed 500 hours of 

operation in the season, even though that is a significant overestimate of their use.
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 8 of 93

• Annual emissions from the small oil spill response equipment are based on operation of 

engines 8 hours per day for the entire 120-day season, even though they will only be 

used for training exercises; this is a significant overestimate of the equipment’s use. 

• Annual emissions from drilling units do not account for the use of any existing emission 

control systems (e.g., selective catalytic reduction [SCR], catalyzed diesel particulate 

filters [CDPF]) when they are currently installed and will be used to reduce emissions 

(Table 6 identifies the units currently installed with emission control systems). 

• Annual emissions from the support vessels do not account for the use of SCR emission 

control systems when they are currently installed and will be used to reduce emissions 

(Table 6 identifies the vessels and units currently installed with emission control 

systems).

• Annual sulfur dioxide (SO2) emissions are calculated assuming higher, conservative 100 

parts per million (ppm) sulfur content, even though Shell will use Ultra Low Sulfur 

Diesel (ULSD) or a fuel with equal or lower sulfur content (but that will be mixed with 

fuel blending with any residual non-ULSD fuel that remains in the tanks prior to the 

drilling season).

1.0 DRILLING UNITS AND SUPPORT VESSELS

This section identifies the drilling units Shell intends to use for exploration drilling and 

describes the vessels that will support the drilling units. For more detailed information on the 

drilling units and the support vessels, please refer to section 13.0 of the Chukchi Sea EP

Revision 2. 

1.1 Drilling Units

Shell plans to use two drilling units, the Motor Vessel (M/V) Noble Discoverer (Discoverer) and 

the Mobile Offshore Drilling Unit (MODU) Transocean Polar Pioneer (Polar Pioneer), to continue 

its exploration drilling program. Shell presents the known or expected emission units at the 

time of filing this EP Revision 2, but it is important to note that one or more of the engines on 

board the drilling units may change as maintenance or equipment needs demands. 

1.1.1 Discoverer

The Discoverer is a drillship equipped with a propulsion engine, electrically powered thrusters, 

engine-driven electrical generators for the drilling motors, and other self-powered equipment. 

The self-powered equipment includes hydraulic pumps, cranes, boilers, an incinerator, and 

other (mostly emergency-related) small sources. There will be no flares and no hydrocarbonventing sources except for minor amounts associated with the drill cuttings. Table 1 lists the 

emission units associated with the Discoverer.

1.1.1.1 Generator Engines

Power generation for drilling exploration wells involves drilling, casing, cementing, and 

logging. Each activity requires a different level of electrical power consumption. The highest

power consumption is expected to occur when the drilling unit is used to excavate and drill the 

mudline cellar (MLC). (As noted in the EP Revision 2 and discussed in Section 1.2.7 below, 

some or all of the MLCs may be constructed using a separate MLC Remotely Operated Vehicle 

[ROV] system.) Casing, cementing, and logging require minimal power, and generator engine 

demand is reduced during these periods.

Six Caterpillar 3512C generator sets comprise the Generator Engines emission unit group as 

described in Table 1. This system provides the primary power for the drilling as well as the 

ship utilities, and the number of operating units and load levels vary throughout the drilling 

process. 

Each of the six generators is fitted with SCR and CDPF control devices that reduce the nitrogen 

oxide (NOX), particulate matter (PM), carbon monoxide (CO), and volatile organic compound

(VOC) emissions. 

Although at least several of the main generators operate continuously while the Discoverer is 

onsite, other diesel engines (described below) are used only occasionally for specialized and 

intermittent tasks. 

1.1.1.2 Propulsion 

The Discoverer is self-propelled with a single STX-MAN Model 6S42MC7, International 

Maritime Organization (IMO) Tier II, 6,480 kW engine. This engine will be used to propel the 

Discoverer to the drill site, and to assist in holding position while the mooring is connected and 

tensioned. In extreme high winds, the engine may be used to assist the anchors in holding the 

vessel in position. 

1.1.1.3 Hydraulic Power Units

The hydraulic power units (HPU) consist of two approximately 200 kW engines and are used 

primarily for assisting in the rotation of the up to 30-foot-diameter bit for drilling the MLCs. 

These engines may also be occasionally used for other unspecified tasks. 

1.1.1.4 Cranes

The Discoverer has two 450 kW engines that power two cranes used intermittently to move 

materials around the deck and to load/off-load supplies. The operating levels of the crane 

engines are highly variable depending on the weight and type of material being moved. The 

duty cycle consists of lifting a load, swinging the load, lowering the load, and idling while the 

load is disconnected, then swinging back to the position of a new load and idling as it is 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 11 of 93

connected. The only activity that consumes high power is the load lifting; the remainder of the 

cycle is at low power. 

1.1.1.5 Cementing Units

There are two 250 kW cementing pumps on the Discoverer. These cementing units are used 

intermittently to force liquid slurry of cement and additives down the casing and into the 

annular space between the casing and the wall of the borehole. The cementing units are also 

used intermittently as high-pressure pumps for hydrostatically testing various types of well 

equipment and drilling components such as the wellhead connections and the blowout 

preventer. 

1.1.1.6 Logging Unit, Compressor, and Sidewall Core Tool Engines

The logging unit, compressor, and sidewall core tool engines are portable equipment associated 

with the planned acquisition of a standardized subsurface evaluation program at each drill site. 

This portable equipment will provide the energy to run the electric wireline logging (EWL) 

program, the Zero-offset Vertical Seismic Profile (ZVSP) program, and the sidewall coring 

program at each drill site. The compressor required to conduct the ZVSP program will be used 

infrequently to collect localized geophysical data at various depths in each well. 

1.1.1.7 Emergency Generator

The Discoverer has a Caterpillar 3412 engine driving a 507 kW emergency generator to power

basic drillship utilities if the primary power system is inoperable. It is capable of powering only 

domestic and worker safety devices and not the drilling equipment. There are no planned uses 

of the emergency generator except weekly exercising, which involves operation for 

approximately 20 minutes. 

1.1.1.8 Lifeboats 

The Discoverer has four lifeboats, each equipped with a Sabb 29.5 horsepower (hp) engine. 

Vendor data are provided in Attachment F. The only planned use of the lifeboats is monthly 

exercising to comply with Coast Guard requirements. 

1.1.1.9 Boilers

The Discoverer has two diesel-fired boilers to provide domestic and workspace heating. 

Typically, only one boiler is operating at a time. 

1.1.1.10 Waste Incinerator

Domestic and other non-hazardous materials are to be incinerated as needed. This man-campstyle incinerator is a two-stage, batch-charged unit capable of burning 276 lb/hr of solid trash. 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 12 of 93

1.1.2 Polar Pioneer

The Polar Pioneer is a semi-submersible MODU that is capable of operating in harsh 

environments and variable water depths. The Polar Pioneer can slowly move using the eight 

onboard electric thrusters; however, it is customary for the Polar Pioneer to be towed on location. 

The Polar Pioneer is kept on a drilling location with a conventional mooring system. The Polar 

Pioneer contains main generator engines, boilers, a compressor engine, and an incinerator. Table 

2 lists the emission units associated with the Polar Pioneer.

b See Attachment D for a complete list of the emission units and ratings. 

1.1.2.1 Generator Engines

Five Bergen KVG-18 diesel engines, rated at 3,890 hp each, drive five 2,750 kW AC generators, 

which comprise the Generator Engines emission unit group described in Table 2. Because 

cementing equipment and cranes are electrified, the Polar Pioneer generators provide the 

primary power for the drilling as well as the ship utilities, and the number of units and load 

levels vary throughout the drilling process. 

Although at least several of the main generators operate continuously while the Polar Pioneer is 

onsite, other diesel engines (described below) are used only occasionally for specialized and 

intermittent tasks. 

1.1.2.2 Hydraulic Power Units

The HPUs consist of two approximately 250 hp engines and are used primarily for assisting in 

the rotation of the up to 30-foot diameter bit for drilling the MLCs. These engines may also be 

used occasionally for other unspecified tasks. 

1.1.2.3 Logging Unit, Compressor, and Sidewall Core Tool Engines

The logging unit, compressor, and sidewall core tool engines are portable equipment associated 

with the planned acquisition of a standardized subsurface evaluation program at each drill site. 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 13 of 93

This portable equipment will provide the energy to run the EWL program, the ZVSP program,

and the sidewall coring program at each drill site. The compressor required to conduct the 

ZVSP program will be used infrequently to collect localized geophysical data at various depths 

in each well. 

1.1.2.4 Emergency Generator Engine

The Polar Pioneer has a TEJOS MTU 12-396 1,120 kW emergency generator to power basic drill 

unit utilities if the primary power system is inoperable. It is capable of powering only domestic 

and worker safety devices and not the drilling equipment. There are no planned uses of the 

emergency generator except weekly exercising, which involves operation for approximately 20 

minutes at loads up to capacity. 

1.1.2.5 Small Emergency Engines

The Polar Pioneer has a Rescue Boat equipped with a Harding 212 hp engine, four lifeboats each 

equipped with a Vetus 52 hp engine, a forward fast rescue craft with a Bukh 144 hp engine, and 

an Aft fast rescue craft with a Volvo 147 kW engine. The only planned use of the boats is 

monthly exercising to comply with Coast Guard requirements. In addition, an emergency start 

compressor engine with a Hatz 11 hp engine is onboard the Polar Pioneer.

1.1.2.6 Boilers

The Polar Pioneer has two diesel-fired boilers to provide domestic and workspace heating.

1.1.2.7 Waste Incinerator

Domestic and other non-hazardous materials are to be incinerated as needed. This incinerator 

is a multi-chamber unit capable of burning 100 kilograms per hour (kg/hr) of solid trash. Its 

incineration capacity is limited to 500 kilocalories per hour (kcal/hr) (580 kW) of heat.

1.2 Support Vessels

The drilling units will be supported by ice management vessels, anchor handlers, science 

vessels, support tugs, offshore supply vessels (OSVs), oil spill response vessels (OSRVs), 

tankers, and other vessels as described in the following sections. 

1.2.1 Ice Management and Anchor Handling Vessels

The ice management and anchor handling vessels are expected to consist of five contracted 

ships: two primary ice management vessels and three anchor handling vessels. An anchor 

handling vessel will provide close support to each drilling unit or work to preset anchors at 

another drill site, while other primary ice management vessels will normally work several miles 

upwind of each drilling unit and may monitor the leading edge of any ice floe of possible 

concern, far upwind up to 30 nautical miles from a drilling unit as described under Appendix G

of the EP Revision 2. These activities are necessary for managing ice at distances that provide 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 14 of 93

adequate response time for drilling units to get off a well and anchor in case of encroaching ice 

that cannot be managed. These response times may vary depending on the drilling stage of the 

well hole.

Managing ice involves deflecting or, in extreme cases, fragmenting ice floes that could impact 

the drilling unit when it is drilling. Removal of ice buildup on the upstream side of the drilling 

unit by “bow washing” may also occur. Bow washing involves backing the anchor handling

vessel close to the drilling unit, and pushing the ice to one side or the other with its propeller 

wash, thereby clearing the ice.

1.2.2 Science Vessels

Two science vessels are responsible for monitoring drill discharges and other science-related 

tasks. The vessels will sample drilling plume effluent during certain phases of the well drilling. 

Section 13a of the EP Revision 2 provides a description of drill discharge monitoring conducted 

by the science vessels. These vessels may also serve to conduct other tasks when not required to 

conduct discharge monitoring.

1.2.3 Support Tugs

Tug boats will provide support to each of the drilling units. Two tugs will be used to deliver 

the Polar Pioneer to the drilling location and will remain on location in standby mode during 

drilling operations in case the Polar Pioneer must leave location quickly. In addition, another 

single tug will escort the Discoverer to the drill site, assist during mooring, and depart when no 

longer required. For most of the drilling season, the tugs located onsite will be anchored or will 

be operated at low speed. 

1.2.4 Offshore Supply Vessels

Three OSVs will shuttle equipment and supplies between the drilling units and shore base 

locations that are out of the Program Area. For example, an OSV will transit to the Discoverer,

and then position itself in dynamic positioning (DP) mode beside the drilling unit for a day or 

longer for material or personnel transfer. At any one time, at most only one OSV is expected to

be at each drill site location off-loading supplies.

1.2.5 Oil Spill Response Vessels

The OSRVs at the Burger Prospect will include a main OSRV equipped with three 34-foot work 

boats, and an oil spill response (OSR) tug/barge. These OSRVs will be used in the unplanned 

and unlikely event of an oil discharge to the water. During the drilling season, these vessels 

will primarily be used during refueling operations to protect against possible spills and will be 

located near the refueling Arctic oil storage tanker (OST). These vessels will be available to both 

the Discoverer and the Polar Pioneer. 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 15 of 93

The work boats will remain on the deck of the OSRV and be deployed in the water for training, 

drills, and response events. Two work boats will be used to tow containment booms, while a 

third will be used as a backup, for crew changes, and for re-fueling. OSRVs will have on-water 

drills at a maximum frequency of once per day.

1.2.6 Arctic Oil Storage Tanker

An Arctic OST will reside near the drilling units, and is expected to be staged at the Burger 

Prospect for the purpose of refueling all the vessels. In the unlikely event of a well-control 

incident, it will also serve as a receiver of any oil skimmed by the OSRVs. The tanker will be 

anchored for most of the drilling season, and refueling is expected to involve the other vessel 

moving to the tanker, with one or more vessels providing booming support during fuel 

transfers. An onboard incinerator may exist to burn solid waste. 

A second OST will be inside the Program Area (i.e., Lease Sale 193 Area) during exploration 

drilling but not within the 25-mile radius. Therefore, no emission estimates are provided for the 

second tanker in the AQRP or NEPA emission inventories. The emissions associated with this 

second OST are comparable to the Arctic OST. In the event of an extended well-control incident, 

the second OST will transit to the Burger Prospect to provide increased storage capacity for any 

collected oil.

1.2.7 MLC ROV System Vessel

As described in the EP Revision 2, a vessel capable of operating in DP may be used to provide 

equipment to excavate MLCs at the Burger Prospect independently of the main drilling units. 

The MLC ROV system equipment on this vessel includes a dedicated engine to drive 

specialized underwater gear on or near the seafloor. Section 2d of the EP Revision 2 provides a

description of the MLC ROV system and the anticipated use of the MLC ROV system vessel.

1.2.8 Candidate Vessels

Each of the above-listed support vessels may be contracted on a year-to-year basis, and Shell is 

not certain that the vessels currently described for the project will be available for each drilling 

season. Table 3 identifies the categories of support vessels and the currently anticipated vessels

to be located within 25 miles of one of the drilling units while conducting exploratory drilling. 

In addition to the vessels listed in Table 3, other vessels will be located outside of the Chukchi 

Sea program area and will provide logistical support (see the EP Revision 2, Table 13.a-3). 

Table 4 lists the emission units associated with each of the support vessels.

2.0 OFFSHORE AIR EMISSIONS

Section 2.1 of this chapter describes the activity of the vessels and the emission units on them. 

Section 2.2 identifies emission factors for each pollutant and emission unit. Together, the 

activity level and emission factors enable the calculation of short-term and annual emissions. 

Section 2.3 of this chapter presents the emissions as appropriate for the AQRP emission 

inventory that is estimated according to 30 CFR Part 550 Subpart C, while section 2.4 presents 

emissions to support the NEPA emission inventory. 

Air pollutants addressed here are NOX, CO, particulate matter (PM10 and PM2.5), VOC, SO2, lead 

(Pb), and greenhouse gases (GHG). Short-term emissions are expressed as pounds of pollutant 

per hour (lb/hr). Long-term emissions are presented as tons of pollutant per year. In effect, the 

long-term emissions represent annual emissions over a maximum 120-day drill season, and the 

terms long-term, seasonal, and annual emissions are used interchangeably. 

2.1 Vessel and Emission Unit Activity

Calculated short-term emissions are based on engine nameplate ratings, modified by limitations 

established from a combination of safety policies and good engine care policies. In practice, 

maximum continuous power ratings of marine engines are typically 10 to 20 percent below

nameplate power ratings. Such good engine operating practices extend equipment life.1 In 

these calculations, the maximum operating rate for each engine is assumed to be 80 percent of 

the nameplate rating in both the AQRP and NEPA inventories. In addition, the 80 percent 

short-term maximum load was used along with the engine or engine group aggregate rating to 

determine the maximum aggregate rating. All boilers and incinerators are assumed to have a 

maximum load of 100 percent for both the AQRP and NEPA inventories.

Annual emissions from the drilling units are based on continuous operation of engines (at 80

percent load) for the entire 120-day season. To calculate annual emissions from support vessels, 

Shell has committed to annual fuel restrictions on the support vessels that are based on 2012 

operational data, information supplied by the vessel owners or operators, or anticipated 

seasonal use. The proposed fuel restrictions apply to main generation and propulsion 

equipment on the support vessels. The proposed annual fuel restrictions for the support vessels 

presented in Table 5 are applied to both the AQRP and NEPA emission inventories. Limited 

fuel combusted by support vessels outside of the 25-mile radius of the drilling units is expected 

to result in emissions that are well dispersed. These fuel restrictions result in an emission 

 1 Documentation of this practice is further explained in the January 11, 2012, letter from Susan Childs to the U.S. Environmental 

Protection Agency’s (EPA’s) Natasha Greaves (included under Attachment E). This practice was applied during the actual 2012 

source testing required under the EPA air permit and was described under the Discoverer Drillship Test Protocol submitted to EPA’s 

Natasha Greaves on February 22, 2012. EPA demonstrated concurrence with the 80 percent assumption by issuing permits and 

consent orders based on applications that included emission inventories and modeling performed using the 80 percent maximum 

power limit. The permits included fuel restrictions and emission limits that were calculated based on the 80 percent assumption.

reduction of 44 to 90 percent, depending on the vessel (see Attachment D, Table D-13 for 

additional details). For similar vessels, a combined fuel restriction is proposed for similar 

vessels within the group. This applies to the Ice Management group, consisting of the Fennica

and Nordica, and the OSV-type, consisting of the Harvey Gulf Tiger-class vessels, the Sisuaq and 

Supporter.

2.2 Emission Factors

NOX, CO, PM, VOC, and Pb emissions are calculated based on an activity level (discussed in 

Section 2.1) and an “emission factor” that is expressed as a mass of emissions for a given activity 

level. The emission factors were selected based on a hierarchy of available data. First, when 

available, emission tests of a specific engine or group of engines (referred to as a source test)

were used to determine emission factors. If source test data were not available, emission factors 

provided by engine vendors were used. If neither source tests nor vendor data were available, 

emission factors were selected from the EPA’s compilation of emission factors (commonly 

referred to as AP-42). 

There are two exceptions to this hierarchy. First, the NOX emission factor for the Discoverer

propulsion engine is based on IMO Annex VI, Tier 2. Second, SO2 emissions from diesel 

combustion are calculated based on sulfur content of the fuel, assuming 100 parts per million by 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 21 of 93

volume (ppmv) to account for any fuel blending that may occur when ULSD or lower sulfur 

content fuels are added during the drilling season to the residual fuels in the tanks that may 

exist prior to the start of the exploration season.

In the AQRP and NEPA emission inventories, Shell has elected to apply emission factors with 

pollutant reductions to account for some of the existing control technologies that are currently 

installed on drilling units and support vessels. Emission factors with emission controls applied 

are only used where reductions are necessary to demonstrate compliance with these programs. 

For example, the Discoverer, Fennica, Nordica, Aiviq, Tor Viking, and Nanuq vessels are currently 

equipped with CDPF and OxyCat emission controls on certain equipment to reduce PM, CO, 

and VOC emissions. However, these emission reduction technologies are only applied to 

emission factors in the NEPA emission inventories. CDPF and OxyCat emission reduction 

technologies are not applied under the AQRP emission inventory because these reductions are 

not necessary for demonstrating compliance under the AQRP. 

The Discoverer primary generators have been retrofitted with CleanAIR’s E-PODTM system to 

actively reduce NOX, using SCR technology. NOX reacts selectively with ammonia across a 

catalyst and is reduced to nitrogen and water. The E-PODTM combines SCR technology with 

oxidation catalysts or particulate filters that reduce PM, CO, and hydrocarbon emissions as 

well. The Aiviq’s propulsion and generator engines also contain an E-PODTM system. The 

Fennica, Nordica, and Tor Viking main engines have been retrofitted with a different SCR and 

oxidation catalyst system for the control of NOX, PM, CO, and VOC emissions. The Nanuq’s

propulsion and generator engines have been retrofitted with CleanAIR’s PERMITTM filter 

system for the control of PM, CO, and hydrocarbons. Table 6 summarizes the emission units 

with emission controls.

As shown in Table 6, Shell has installed SCR pollutant control technologies on certain 

equipment on the drilling units and support vessels. However, no NOX pollutant reductions for 

the SCR emission control technologies currently installed are applied to the emission factors 

used in the AQRP and NEPA emission inventories. The SCR emission reductions are not 

necessary to demonstrate compliance under the AQRP or NEPA.

As stated, the AQRP emission inventory assumes that 100 ppmv sulfur content fuel is 

combusted to account for any fuel blending that may occur when ULSD or another fuel with 

lower sulfur content is added to any residual fuel that may exist in a tank prior to the start of 

the exploration season. But, the AQRP emission inventory does not apply any of the existing 

emission control systems listed in Table 6 because they are not required to demonstrate that the 

project emissions are below the BOEM exemption thresholds. The NEPA emission inventories 

account for the use of reduced sulfur fuel on all drilling units and vessels, and also 

acknowledge the reduction of PM from existing emission control devices on the Fennica, 

Nordica, Aiviq, Tor Viking, and Nanuq because these are the only emission controls required to 

demonstrate compliance under NEPA. Even though emissions are not calculated with all 

identified emission reductions, Shell will attempt to utilize those controls not applied in the 

AQRP and NEPA emission inventories during exploration drilling.

2.2.1 Source Test Data

Over several years, Shell had numerous emission units source-tested onboard the Discoverer and 

a number of the candidate support vessels. In 2012, prior to exploration drilling, over 800 

various source tests were conducted, as required by the now terminated EPA Discoverer

Prevention of Significant Deterioration Permit to Construct (R10OCS/PSD-AK-09-01) and the 

Kulluk Title V Permit (R10OCS030000). Shell has elected to use these source test results as 

applicable for a number of the emission units. 

In 2007, NOX emissions from the Fennica were measured. These source tests were completed 

prior to the installation of the SCR control system on the main propulsion engines. In both the 

AQRP and NEPA emission inventories, Shell uses the measured uncontrolled NOX emissions 

from the 2007 tests for both the Fennica and the Nordica, a sister ship to the Fennica. 

Also in 2007, as required by the EPA Kulluk Air Quality Control Minor Permit (R10OCS-AK-07-

01), NOX emissions were measured from two engines on the Tor Viking. These source tests were

conducted with and without the SCR operating. In both the AQRP and NEPA emission

inventories, Shell uses the measured uncontrolled NOX emissions from the 2007 tests for the Tor 

Viking. 

Finally, Transocean had the Polar Pioneer main engine #3 source-tested in 2014 to determine 

emission factors for NOX and CO.2 These emission factors are representative of the Polar Pioneer

Generator Engines group, as described in Table 2, and are used in both the AQRP and NEPA 

inventories. 

 2 PM filterable was measured during the test, but the condensable particulate portion was not measured during the test. 

Consequently, the PM source test measurements were not used in these emission calculations. 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 23 of 93

All the source tests were completed at various loads. To calculate emissions for the drilling 

units and support vessels, Shell averaged measured emission factors over all the loads over 

similar engines. For example, the source test results for both Discoverer HPU engines, at two

different loads, were averaged, and a single factor was determined to represent emissions from 

the Discoverer HPU engines group.3

Table 7 lists the emission unit groupings that use source test emission factors in the applicable

emission inventory. Copies of the source test summary tables can be found in Attachment F, 

along with applicable portions of the references provided in section 4.0 of this report.

 3 Because generators typically convert over 90 percent of the energy coming from the engine into electricity, 2012 source test 

emission factors for generators provided in pounds per kilowatt electrical hour (lb/kWe-hr) were converted to lb/kW-hr by 

dividing the average group emission factor by 95 percent. This produced a conservative engine emission factor.

a The controlled emission factor was applied for the AQRP emission inventory because the uncontrolled vendor data PM emission 

factor was less than the controlled source test emission factor. See Section 2.4 for more information.

2.2.2 Vendor Data

In those cases where source test data were unavailable, vendor emissions data were selected, if 

available. In other cases, source test data were available for a controlled engine but an 

uncontrolled emission factor was needed for the emission inventory. 

Because the Discoverer Caterpillar D399 generator engines were replaced in 2013 with 

Caterpillar 3512C engines, the 2012 source test data results for these engines are no longer 

applicable. Vendor data for the Caterpillar 3512C engines were received from Louisiana CAT 

(Attachment F) with Rated Speed “Nominal Data” for NOX, CO, hydrocarbon (HC), and 

particulate matter in lb/hr. These emissions represent uncontrolled engine emissions and were 

converted to grams per kilowatt hour (g/kW-hr) for use in the emission inventories. Even 

though controls are present and will be used throughout the season on the generators, the 

Discoverer generation emission factors do not apply any emission reduction.

Because Discoverer cranes were replaced in 2013, the 2012 source test data results are no longer 

applicable. Liebherr Machines Bulle SA, the manufacturer of the cranes, provided an “Exhaust 

Emission Confirmation” for the installed engine D9508 A7. These emission values are used for 

the Discoverer cranes emission unit group and can be found in Attachment F. 

The Aiviq propulsion engines are Caterpillar C280-12, and the “Diesel Engine Technical Data” 

sheet was provided by Caterpillar. Emissions “Nominal Data” are provided on the sheet and 

the uncontrolled NOX, CO, and total hydrocarbon (THC) emission rates were used for the Aiviq
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

propulsion engines emission unit group. The Caterpillar C280-12 technical data sheet is 

provided in Attachment F. Two tug boats proposed to be part of the support vessels, the Ocean 

Wind and Ocean Wave, have propulsion engines that are Caterpillar C280-12 engines. The 

vendor uncontrolled NOX, CO, THC, and particulate emission rates have been used for these

engines as well.

Finally, a Cummins KTA50-G3, 1,340 hp engine will be placed onboard the MLC ROV system 

vessel to excavate MLCs. A Cummins Exhaust Emissions Data Sheet for this engine is provided 

in Attachment F. The continuous power emissions of HC, NOX, CO, and PM are used in both 

emission inventories. Table 8 lists the emission unit groups with vendor emission factors.

2.2.3 EPA’s AP-42 Compilation of Air Pollutant Emission Factors 

Where emissions data are not available from source tests or vendors, emission factors from 

EPA’s AP-42 have been applied.

Diesel internal combustion (IC) engine emission factors from AP-42 Chapter 3 are applied for 

Stationary Internal Combustion Sources, Section 3.3, Gasoline and Diesel Industrial Engines, 

Table 3.3-1 (<600 hp). In addition, factors are applied from Section 3.4, Large Stationary Diesel 

and All Stationary Dual-fuel Engines, Table 3.4-1 (>600 hp). Table 9 and Table 10 list these 

emission factors.

Boiler emission factors were taken from AP-42’s Chapter 1 for external combustion sources, 

Section 1.3 for fuel oil combustion. NOX, CO, and filterable PM emission factors for boilers less 

than 100 MMBtu/hr that fire distillate oil from Table 1.3.1 are applied. The total condensable 

PM for No. 2 oil-fired emission factor, 2 lb/k-gal, from AP-42 Table 1.3-2 is applied. The 

filterable PM and total condensable PM were combined to determine the PM10 and PM2.5 boiler 

emission factor of 3.3 lb/k-gal. Finally, the non-methane total organic compounds (NMTOC) 

emission factors for commercial/institutional/residential combustors that fire distillate oil from

Table 1.3-3 are applied. A summary of all the boiler emission factors used from AP-42 Section 

1.3 are listed in Table 11.

Incinerator emission factors from AP-42’s Chapter 2 are applied for solid waste disposal,

starved-air combustors from Table 2.1-9 are applied. In an effort to be more conservative, the 

uncontrolled PM emission factor for mass burn and modular excess air combustors from Table 

2.1-2 are applied. Finally, the TOC emission factor for industrial/commercial, multiple 

chamber refuse combustors other than municipal waste from Table 2.1-12 is applied. A 

summary of all the incinerator emission factors used from AP-42 Section 2.1 are listed in Table 

12.

2.2.4 Sulfur Dioxide Emissions

Shell has committed to purchase and use ULSD fuel or fuel with lower sulfur content during the 

drilling season. A material safety data sheet (MSDS) for the fuel type Shell intends to use lists 

ULSD with a sulfur content of 15 ppm maximum (Attachment F). However, some of the 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 29 of 93

candidate vessels Shell will lease may not utilize ULSD year round when they are not 

conducting exploratory drilling in the Chukchi Sea. The AQRP and NEPA inventories include 

SO2 emissions that are calculated assuming conservative 100 ppm sulfur content. This higher 

sulfur content accounts for the potential for fuel blending of residual non-ULSD fuel that 

remains in fuel tanks prior to the drilling season with the ULSD that Shell purchases. 

Attachment F also provides a copy of the email from Royal Harris dated April 20, 2011,

providing details on the diesel produced by Tesoro Nikiski. The email states the specific 

gravity of ULSD as 0.8398 using “ASTM D4052 - Standard Test Method for Density, Relative 

Density, and API Gravity of Liquids by Digital Density Meter.” This specific gravity was used 

to calculate the density of diesel as follows:

DDDDDD DDDDDDD = 0.8398 × 8.34

l

gg g (d o w w) = 7.0 l/gg g (1)

In addition, the email supports a net diesel heat content of 131,180 Btu/gallon that was utilized 

in the AQRP and NEPA emission inventories for the calculation of emissions.

2.2.5 Greenhouse Gas Emissions

Greenhouse gases are not a regulated pollutant by BOEM but are relevant to BOEM’s NEPA 

analysis and are presented in Shell’s Environmental Impact Analysis (EIA) addressing the EP 

Revision 2. 40 CFR Part 98, Subpart C, Table C-1 and Table C-2, provide GHG emission factors 

for various types of fuel. The carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) 

emission factors for distillate fuel oil No. 2, municipal waste, and petroleum are used from 

Tables C-1 and C-2 for use in the emission inventories. Table 13 and Table 14 list the emission 

factors used from Part 98 to calculate GHG emissions. These emission factors, along with the 

global warming potentials from Part 98 Table A-1 listed in Table 15, are used to determine the 

CO2 equivalent (CO2e) emissions, also referred to as GHG emissions. Equation 2 below shows 

the CO2e emission factor used for all diesel combustion sources in the NEPA emission 

inventory.

2.2.6 Lead Emissions

Because lead emission factors for diesel-fired internal combustion engines are not provided in 

AP-42 Chapter 3, Sections 3.3 and 3.4, EPA’s Locating and Estimating (L&E) Air Emissions from 

Lead Sources and Lead Compounds report was used. Section 5.2.2 of this report provides an 

emission factor of 2.9E-5 lb/MMBtu for distillate oil-fired gas turbines. These emission factors 

should be representative of any distillate-fired combustion device.

EPA’s AP-42 was used to determine appropriate boiler and incinerator emission factors. A 

boiler emission factor of 9 lb/1012 Btu was used from Chapter 1: External Combustion Sources, 

Section 1.3: Fuel Oil Combustion, Table 1.3-10: Emission Factors for Trace Elements from 

Distillate Fuel Oil Combustion Sources. An incinerator emission factor of 2.13E-1 lb/ton was 

taken from Chapter 2 for solid waste disposal, Section 2.1 for refuse combustors, Table 2.1-2 

(Particulate Matter, Metals, and Acid Gas Emission Factors for Mass Burn and Modular Excess 

Air Combustors). 

2.3 AQRP Offshore Emissions Summary

The AQRP emission inventory addresses the emissions from the “facility,” which is defined at 

30 CFR 550.302 to mean:

any installation or device permanently or temporarily attached to the seabed which is used for 

exploration, development, and production activities for oil, gas, or sulphur and which emits or 

has the potential to emit any air pollutant from one or more sources. All equipment directly 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 31 of 93

associated with the installation or device shall be considered part of a single facility if the 

equipment is dependent on, or affects the processes of, the installation or device.

In addition to presenting emissions for the drilling units, Shell also presents aggregate 

emissions for the facility that include the support vessels operating within 25 miles of the 

drilling units. 

The AQRP emission inventory was developed for sources without consideration of emission 

control technologies, but does include good engine operating practices (i.e., engine power 

restrictions for ensuring extended equipment life) and proposed seasonal fuel restrictions for 

the support vessels. Note that the proposed fuel restrictions apply only to main generation and 

propulsion equipment of some of the support vessels.

The AQRP emissions are based on the conservative assumption that all engines on the 

Discoverer and the Polar Pioneer operate every hour of the season at 80 percent load. The boilers 

and incinerators associated with the drilling units are assumed to operate at rated capacity 

every hour of the season. 

Emissions from the Discoverer Support Tug (Lauren Foss) generator and thruster engines are 

based on 21 days per season of operation. 

Emissions from all emergency generator engines, lifeboat engines, rescue crafts, and seldomused engines onboard the support vessels are based on a conservative assumption of 500 hours

of operation per season. 

Emissions from the small OSR equipment used during training exercises are based on operation 

of eight hours per day and 120 days of operation per season. 

Emissions from propulsion and generator engines onboard the support vessels are based on 

seasonal fuel restrictions except for the following engines:

• Fennica – Harbor Set Generator Engine and Emergency Engine

• Nordica – Harbor Set Generator Engine and Emergency Engine

• Ocean Wind – Generator Engines

• Ocean Wave – Generator Engines

• Nanuq – Generator Engines, Emergency Engines, and OSR Equipment Engines

• Kvichaks – Propulsion and Generator Engines

• Guardsman/Klamath – Generator Engines and OSR Equipment Engines
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 32 of 93

• MLC ROV System Vessel (Harvey Spirit) – Generator Engines, Thruster Engine, 

Emergency Engine, and MLC ROV System Engine

These engines and the remaining units onboard the drilling units and support vessels are 

estimated based on 24 hours per day, 120 days per season, for a total of 2,880 hours per season

with exception of “Emergency” and “OSR Equipment” engines. Table 16 presents the estimated 

AQRP projected annual emissions. Attachment A provides the detailed emission calculation 

summaries.

2.4 NEPA Offshore Emissions Summary 

The NEPA emission inventory is similar to the AQRP emission inventory except that PM 

emission reductions have been applied where PM emission control equipment currently exists 

on a support vessel. Although the NEPA analysis presented in Attachment B to Appendix C

(the EIA) also addresses emissions from the onshore facilities, vehicles, and aircraft trips, the 

onshore emissions are addressed in Section 3.0 of this report rather than in this section. Both

the AQRP and NEPA inventories are limited to a 120-day maximum drilling season.

Although emission controls will be in place (and operational) on many of the largest engines, 

Shell chooses to demonstrate that exploration operations will not exceed BOEM impact criteria 

even if the benefits of NOX or CO emission controls are not taken into consideration. The sole 

exception to this is the Aiviq propulsion engines; because the uncontrolled vendor data PM 

emission factor was less than the controlled source test emission factor, the controlled emission 

factor is used in both the AQRP and NEPA emission inventories.

The support vessels that contain PM emission controls are identified in Table 17.

Anchor Handler Aiviq – Propulsion Engines DOC

Anchor Handler Aiviq – Generator Engines CDPF

Ice Management Nordica – Propulsion and Generator Engines OxyCat

OSRV Nanuq – Propulsion and Generator Engines CDPF

The Fennica and Nordica Harbour Generators are assumed not to operate during drilling season 

because this equipment is not required while away at sea.

Table 18 presents the NEPA emission inventory offshore projected peak hourly emissions by 

group for the Discoverer, the Polar Pioneer, and their support vessels. Table 19 presents the 

offshore projected annual NEPA emission inventory emissions by group. 

During exploration activity, the support vessels will virtually always operate within 25 miles of 

one of the two drilling units. The obvious exception to this is when OSVs are in transit to Dutch 

Harbor or other resupply ports. It is also possible that on occasion the ice management vessels 

or other support vessels would travel farther than 25 miles. This activity is accounted for in the 

proposed annual fuel restrictions and, therefore, the emissions estimates.

Ships traveling farther than 25 miles from the drilling units would disperse the emissions to a 

greater extent than when they are closer to the drilling units. Because the dispersion modeling 

conducted in support of the NEPA inventory concentrates all emissions within 25 miles of the 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 37 of 93

drilling units, it results in predictions that are higher than those expected if some vessels 

venture outside the 25 mile radius. Consequently, additional modeling of that scenario is not 

warranted.

3.0 ONSHORE AIR EMISSIONS

Land-based emissions include those from personnel and supply transported to and from the 

drill site, and any housing emissions dedicated to the project. The on-land activities associated 

with the exploration activities are likely to include support facilities in Barrow. These facilities 

in Barrow include a man-camp, storage facilities, and an aircraft hangar, requiring heat and 

power. Other possible minor support activities may occur in Wainwright at existing leased 

facilities. Transportation of personnel and materials to and from the airport would be by 

automobiles, vans, or pickup trucks, fueled with diesel. Transport to and from the vessels to 

shore will be by up to three helicopters, stationed in Barrow. Additional fixed wing aircraft will 

be used for crew transport. Communications may be through existing communications center 

networks or leases from existing facilities. 

3.1 Aircraft Activity

Emissions from aircrafts are estimated using the Federal Aviation Administration’s (FAA) 

Emissions and Dispersion Modeling System (EDMS). EDMS is a combined emissions and 

dispersion model for assessing air quality at civilian airports and military air bases. The model 

was developed by the FAA in cooperation with the United States Air Force (USAF). The model 

is used to produce an inventory of emissions generated by sources on and around the airport or 

air base, and to calculate pollutant concentrations in these environments.

As described in Section 13 of the EP Revision 2, Shell intends to operate the following aircrafts 

with the exploration drilling program:

• (3) crew change helicopters

• (1) search and rescue (SAR) helicopter

• (1) fixed-wing aircraft for crew transport, with an option for a helicopter

• (1) fixed-wing aircraft for ice reconnaissance

• (1) fixed-wing aircraft for Protected Species Observer (PSO) flights

As described in Table 13.a-3 of the EP Revision 2, Table 20 lists the purpose, proposed aircraft 

types, and trip frequencies used to determine the air emissions.

1 An additional helicopter may be substituted for the fixed-wing aircraft for crew transport. The change in emissions from the 

alternate aircraft is minimal.

The EDMS estimates emissions for a landing/take-off (LTO) cycle. The aircraft that was closest 

in size and engine capacity was used to estimate emissions from one LTO cycle. The emissions 

were then multiplied by the total number of LTOs for the season. Total emissions from these 

aircraft along with an analysis of the EDMS LTO emission estimates for each scenario can be 

found in Attachment C2. The EDMS output file can be found in the Appendix K folder of the 

flash drive.

3.2 Hangar/Storage Building Activity

A hangar/storage building located in Barrow at the airport is expected to be heated by a small 5 

MMBtu/hr, natural-gas-fired boiler, and operational 12 hours per day for 168 days per season. 

The make and model of this boiler is currently unknown; therefore, emission factors from AP42’s Chapter 1 for external combustion sources, Section 1.4 for natural gas combustion were 

selected. Table 21 lists these emission factors, and total emissions from this source can be found 

in Attachment C1.

3.3 Camp Activity

3.3.1 Existing 75-person NARL Camp Activity

The current 75-person camp located near the Naval Arctic Research Laboratory (NARL) is 

powered by two John Deere PowerTech 13.5L, 448 kW, diesel generators. One generator serves 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 46 of 93

as the primary generator and the other is a backup generator. Similar to the vessel internal 

combustion engines, it is assumed that “good engine operating practices” will be used to extend 

the life of the generators. Therefore, the maximum load is assumed to be 80 percent for 

emission calculations. In addition, it is assumed that the backup generator will only operate 1 

hour per week for routine maintenance checks. 

The John Deere generators are EPA-certified Tier 3; therefore, 40 CFR 89.112 Nonroad, Tier 3 

standards have been selected to calculate emissions. Because there is no Tier 3 VOC emission 

factor, the Tier 1 standard was (conservatively) selected. Finally, SO2 emissions were calculated

assuming 100 ppm sulfur content (see Section 2.2.4), and lead emissions were calculated using 

EPA’s Locating and Estimating Air Emissions from Lead Sources and Lead Compounds report 

(see Section 2.2.6). Table 22 lists the emission factors for these engines, and total emissions can 

be found in Attachment C1.

3.3.2 K/D/R Facility at NARL Camp Activity

The existing camp near NARL is serviced by a kitchen/dining/recreation (K/D/R) facility that 

is powered by a Caterpillar 3412CDITA, 725 kWe diesel-fired generator engine. The K/D/R

generator is located near the existing NARL camp power modules. Vendor data are used to 

estimate criteria pollutant emissions. Finally, SO2 emissions were calculated assuming 100 ppm 

sulfur content (see Section 2.2.4) and lead emissions were calculated using EPA’s Locating and 

Estimating Air Emissions from Lead Sources and Lead Compounds report (see Section 2.2.6). 

Table 23 lists the emission factors for this engine, and total emissions can be found in

3.3.3 40-person Camp near NARL Camp Activity

Shell will lease accommodations at the existing 40-person Ukpeaġvik Iñupiat Corporation (UIC) 

modular construction camp; this camp is now at the UIC storage location in Barrow but would 

be relocated by UIC to the existing UIC pad near the NARL camp. This is a separate location 

from the existing UIC camp near NARL described in Section 3.3.1. This 40-person camp will be 

tied to the grid for power; there are no other emission units onsite. 
Shell Chukchi Sea Exploration Plan, Revision 2 February 6, 2015

Appendix K – AQRP and NEPA Emission Inventories Page 48 of 93

3.4 Vehicle Activity

Vehicle emissions were estimated using EPA’s Office of Transportation and Air Quality 

(OTAQ) Motor Vehicle Emission Simulator (MOVES). Vehicle emissions are estimated to occur 

during the transportation of personnel and materials to and from the airport using diesel-fueled 

automobiles, vans, or pickup trucks. The MOVES model was run to estimate emissions from a 

passenger truck, model year 2012, in the Alaska North Slope Borough. The MOVES program 

provides hourly emission estimates for each weekday and weekend day for every month. It 

was assumed that the emissions for this project will occur during July, August, September, and 

October. The seasonal emissions were then conservatively estimated to occur 12 hours per day

for the total 123 days (July 1st – October 31st). Hourly emissions were estimated by selecting the 

maximum hourly emissions for each pollutant for the same timeframe. The emission values can 

be found in Attachment C3, and the MOVES output file can be found in the Appendix K folder 

of the flash drive.

OCS/PSD Air Quality Permits 

U.S. EPA - Region 10, AWT-107 

1200 Sixth Avenue, Suite 900 

Seattle, Washington, 98101 

January 11, 2012 

Re: Frontier Discoverer Source Tests 

Shell OCS Exploration Program 

On September 19, 2011, EPA issued Shell Gulf of Mexico Inc. (Shell) Prevention of Significant 

Deterioration Permits to Construct for the Noble Discoverer drill ship operations in the Chukchi 

and Beaufort seas. The PSD permits require measurement of emissions from most of the 

emission units on the Discoverer and on the Discoverer’s associated fleet via source testing. 

The purpose of this letter is two-fold. First, we request EPA concurrence with Shell’s intent to 

measure at on-shore facilities emissions from certain engines not now on the Discoverer. 

Secondly, we request EPA concurrence that physical or contractual limitations imposed on 

engine operating capacity can be considered when defining 100 percent load (and, 

correspondingly, fractions of that 100 percent load). As explained below, we believe Shell’s 

approach meets the intent of the permit while ensuring a safer and equally realistic testing 

process. 

On-shore testing

Shell intends to test the main generator engines, the port crane engine, the boilers, and the 

incinerator on the Discoverer because these emission units are permanently installed. However, 

none of the other engines that require testing are currently onboard the drill ship; in fact, most of 

the other engines are portable and routinely removed from the drill rig at the end of each drill 

season. 

The PSD permits require Shell to test certain engines prior to the beginning of the drill season. 

Because of other construction activities that will be undertaken at the same time on the 

Discoverer, and the limited deck space available for those activities as well as source test 

equipment, testing certain engines at an on shore site will simply allow for a higher level of 

safety for testing, and personnel during testing. Shell would maintain that the physical location 

of the equipment during testing should not be an issue here, as the operating range necessary to 

be maintained to confirm accurate testing will need to be maintained whether the engine is 

physically located on the Discoverer at the time of testing or not.

Shell therefore proposes to test the starboard crane engine, the Mud Line Cellar Hydraulic Power 

Unit engines, the Mud Line Cellar Air Compressor engines, the cementing engines and the C7 

logging winch engine at an on-shore facility. It is likely that testing will take place at NC 

Machinery, south of Tukwila, Washington. Although engine-specific information will be 

included in test protocols, dynamometers or hydraulic flow restrictors are likely to be used to 

load these engines to the operating rates required by the permits. 

Definition of engine load

The Discoverer PSD permits require Shell to measure emissions from the engines powering the 

main generators, mud line cellar compressor engines, hydraulic pressure unit engines, crane 

engines, and cementing and logging engines at multiple loads. However, a number of these

engines power equipment that, for various reasons, preclude operating, and as an extension 

testing, the engine to its full rated capacity. In some other cases, where the emissions units are 

owned by others, there are contractual restrictions on the maximum allowable engine operating 

loads. 

In both cases, Shell proposes to redefine the maximum operating rate of the engine (100 percent 

load) to reflect those restrictions. Partial load testing (e.g., 50% load or 80% load) would also be 

correspondingly adjusted relative to this redefined maximum load condition. Below please find 

explanations of why, and examples of how, this would work for the subject engines. 

FD 1-6. Main Generators 

Noble, the owner of the Discoverer, has established 800 kW as the maximum operating rate for 

the generators, and has installed an electrical distribution system with controls that limit the 

engines’ operating rate accordingly. This operating rate is nearly 20 percent lower than the 988 

kW nameplate rating on the engine. With this contractual and operational restriction in place, 

Shell submits that an engine operating rate that results in 800 kW output reflects the true 100 

percent engine load to be encountered during our OCS drilling operations, and that the “100% 

load” source tests should take place at this restricted engine operating rate. Similarly, source 

tests at 75% and 50% load should be conducted at engine operating rates that generate 600 and 

400 kW, respectively. 

FD 14-15. Deck Cranes 

Each of the deck cranes engines are rated at 365 HP. The PSD permit requires testing at 60-80% 

and 80-100% loads. 

Crane engine testing is challenging, as the engine is only one part of the crane hoisting system. 

The maximum load on the system is defined by the boom capacity, which for the cranes on the 

Discoverer is much less than the hoisting capacity of the corresponding engine and winch. One 

hundred percent boom capacity for the cranes to be used on the Discoverer translates to about 

310-320 HP of engine/winch capacity, which is below their nameplate capacity. Because the 

Attachment E1, Page 2 of 3
EPA Region10 

January 11, 2012 

Page 3 

cranes cannot physically exceed the boom capacity, the engines are functionally limited to a 

lower load than their name plate rating. There is a boom radius-load indicator and alarm in the 

crane cabs that indicates when the load is approaching 100 percent of boom capacity. In this 

case, then, it is appropriate to consider the maximum load the engines will operate to be 320 HP. 

Thus, Shell proposes to define 100 percent load for these engines as 320 HP. 

FD 12-13. Mud Line Cellar Hydraulic Power Unit Engines. 

The MLC HPU engines are rated at 322 HP. The PSD permit requires testing at 50-70% and 80-

100% loads. 

These engines power hydraulic pumps that operate hydraulic motors on the MLC bit. The 

hydraulic motor capacity is limited to 150 gallons per minute at 2500 PSI, which translates to an 

engine load of about 218 HP. The energy load into the hydraulic motor cannot exceed this value. 

Given this physical limitation, Shell believes the functional maximum load the engine can

operate is at 218 HP, and that we should consider this to be 100% load for testing. 

We request EPA’s written concurrence that testing the starboard crane engine, the Mud Line 

Cellar Hydraulic Power Unit engines, the Mud Line Cellar Air Compressor engines, the 

cementing engines and the C7 logging winch engine at an on-shore facility is consistent with the 

requirements of the Noble Discoverer PSD permits. We also request EPA’s written concurrence 

that we can redefine 100 percent load for the main generators, the crane engines, and the Mud 

Line Cellar Hydraulic Power Unit engines as proposed above. Please contact Pauline Ruddy 

(907.771.7243) if you have questions or require additional information regarding these 

proposals. 

Thank you,

As told in the introduction the PM emission was sampled according to the dust sampling 

standard EN 13284-1. Then the calculated PM mass flow was divided by the average power 

(as for the specific NOX and CO emissions, cf. page 9 Appendix 3).

Polar Pioneer use MGO with 0.05 w-% S as engine fuel. Based on the composition of the 

fuel (13.6 w-% H and 86.2 w-% C) the mole fraction of hydrogen to carbon (H/C ratio) used 

in the calculations for MGO is 1.8800 [1]. To check if the fuel values used in the calculations 

are correct, Ecoxy always compares the calculated excess air ratio based on the O2 and CO2

measurements. In Figure 4 the red and blue lines are the theoretical values for the O2 and CO2

concentrations, respectively. The points plotted in the figure are measured values. The figure 

shows that the measured values are in good accordance with the theoretical values.

TOTAL DERATION FACTORS:

This table shows the deration required for various air inlet temperatures and altitudes. Use this information to help determine actual engine power

for your site. The total deration factor includes deration due to altitude and ambient temperature, and air inlet manifold temperature deration.

AFTERCOOLER HEAT REJECTION FACTORS:

Aftercooler heat rejection is given for standard conditions of 25°C and 150 m altitude. To maintain a constant air inlet manifold temperature, as the air to turbo

temperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcome the lower atmospheric pressure.

This increases the amount of heat that must be removed from the inlet air by the aftercooler. Use the aftercooler heat rejection factor to adjust for ambient and

altitude conditions. Multiply this factor by the standard aftercooler heat rejection.

GENERATOR EFFICIENCY:

Generator power determined with an assumed generator effeciency of 96% [generator power = engine power x 0.96]. If the actual generator efficiency is less than 96%

[and greater than 94.5%], the generator power [ekW] listed in the technical data can still be achieved. The BSFC values must be increased by a factor.

The factor is a percentage = 96% - actual generator efficiency.

SOUND DATA:

Data determined by methods according to TM7080.

SECTION 4. FIRST AID MEASURES

Inhalation : Move to fresh air. Give oxygen. If breathing is irregular or stopped, administer 

artificial respiration. Seek medical attention immediately. 

Skin contact : Take off all contaminated clothing immediately. Wash off immediately with soap 

and plenty of water. Wash contaminated clothing before re-use. If skin irritation 

persists, seek medical attention immediately. 

Eye contact : Remove contact lenses. Rinse thoroughly with plenty of water for at least 15

Ingestion : Do not induce vomiting without medical advice. If a person vomits when lying on 

his back, place him in the recovery position. Seek medical attention immediately. 

Notes to physician : Symptoms: Dizziness, Discomfort, Headache, Nausea, Disorder, Vomiting, Lung 

edema, Liver disorders, Kidney disorders. Aspiration may cause pulmonary 

edema and pneumonitis. 

SECTION 5. FIRE-FIGHTING MEASURES

Suitable extinguishing media : SMALL FIRES: Any extinguisher suitable for Class B fires, dry chemical, CO2, 

water spray or fire fighting foam. LARGE FIRES: Water spray, fog or fire fighting 

foam. Water may be ineffective for fighting the fire, but may be used to cool fireexposed containers. Keep containers and surroundings cool with water spray. 

Specific hazards during fire 

fighting

: Fire Hazard Do not use a solid water stream as it may scatter and spread fire. Cool 

closed containers exposed to fire with water spray. 

Special protective equipment 

for fire-fighters

: Wear self-contained breathing apparatus and protective suit. Use personal 

protective equipment. 

Further information : Exposure to decomposition products may be a hazard to health. Isolate area 

around container involved in fire. Cool tanks, shells, and containers exposed to fire 

and excessive heat with water. For massive fires the use of unmanned hose 

holders or monitor nozzles may be advantageous to further minimize personnel 

exposure. Major fires may require withdrawal, allowing the tank to burn. Large 

storage tank fires typically require specially trained personnel and equipment to 

extinguish the fire, often including the need for properly applied fire fighting foam. 

SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal precautions : Evacuate nonessential personnel and remove or secure all ignition sources. 

Consider wind direction; stay upwind and uphill, if possible. Evaluate the direction 

of product travel, diking, sewers, etc. to contain spill areas. Spills may infiltrate 

subsurface soil and groundwater; professional assistance may be necessary to 

determine the extent of subsurface impact. Ensure adequate ventilation. Use 

personal protective equipment. 
SAFETY DATA SHEET Diesel Low Sulfur (LSD) and Ultra Low Sulfur 

Diesel (ULSD) 

Page 4 of 11 

4 / 11

Environmental precautions : Carefully contain and stop the source of the spill, if safe to do so. Protect bodies of 

water by diking, absorbents, or absorbent boom, if possible. Do not flush down 

sewer or drainage systems, unless system is designed and permitted to handle 

such material. The use of fire fighting foam may be useful in certain situations to 

reduce vapors. The proper use of water spray may effectively disperse product 

vapors or the liquid itself, preventing contact with ignition sources or 

areas/equipment that require protection. Discharge into the environment must be 

avoided. If the product contaminates rivers and lakes or drains inform respective 

authorities. 

Methods for cleaning up : Take up with sand or oil absorbing materials. Carefully shovel, scoop or sweep up 

into a waste container for reclamation or disposal - caution, flammable vapors may 

accumulate in closed containers. Response and clean-up crews must be properly 

trained and must utilize proper protective equipment (see Section 8). 

SECTION 7. HANDLING AND STORAGE 

Precautions for safe handling : Keep away from fire, sparks and heated surfaces. No smoking near areas where 

material is stored or handled. The product should only be stored and handled in 

areas with intrinsically safe electrical classification. 

: Hydrocarbon liquids including this product can act as a non-conductive flammable 

liquid (or static accumulators), and may form ignitable vapor-air mixtures in storage 

tanks or other containers. Precautions to prevent static-initated fire or explosion 

during transfer, storage or handling, include but are not limited to these examples: 

(1) Ground and bond containers during product transfers. Grounding and 

bonding may not be adequate protection to prevent ignition or explosion of 

hydrocarbon liquids and vapors that are static accumulators. 

(2) Special slow load procedures for "switch loading" must be followed to 

avoid the static ignition hazard that can exist when higher flash point 

material (such as fuel oil or diesel) is loaded into tanks previously 

containing low flash point products (such gasoline or naphtha). 

(3) Storage tank level floats must be effectively bonded. 

For more information on precautions to prevent static-initated fire or explosion, see 

NFPA 77, Recommended Practice on Static Electricity (2007), and API 

Recommended Practice 2003, Protection Against Ignitions Arising Out of Static, 

Lightning, and Stray Currents (2008). 

Conditions for safe storage, 

including incompatibilities

: Keep away from flame, sparks, excessive temperatures and open flame. Use 

approved containers. Keep containers closed and clearly labeled. Empty or 

partially full product containers or vessels may contain explosive vapors. Do not 

pressurize, cut, heat, weld or expose containers to sources of ignition. Store in a 

well-ventilated area. The storage area should comply with NFPA 30 "Flammable 

and Combustible Liquid Code". The cleaning of tanks previously containing this 

product should follow API Recommended Practice (RP) 2013 "Cleaning Mobile 

Tanks In Flammable and Combustible Liquid Service" and API RP 2015 "Cleaning 

Petroleum Storage Tanks". 

 : Emergency eye wash capability should be available in the near proximity to 

operations presenting a potential splash exposure. 

 Keep away from food, drink and animal feed. Incompatible with oxidizing agents. 

Incompatible with acids.

Engineering measures : Use adequate ventilation to keep gas and vapor concentrations of this product 

below occupational exposure and flammability limits, particularly in confined 

spaces. Use only intrinsically safe electrical equipment approved for use in 

classified areas. 

Eye protection : Safety glasses or goggles are recommended where there is a possibility of 

splashing or spraying. 

Hand protection : Gloves constructed of nitrile, neoprene, or PVC are recommended. Consult 

manufacturer specifications for further information. 

Skin and body protection : If needed to prevent skin contact, chemical protective clothing such as of DuPont 

TyChem®, Saranex or equivalent recommended based on degree of exposure. 

The resistance of specific material may vary from product to product as well as 

with degree of exposure. 

Respiratory protection : A NIOSH/ MSHA-approved air-purifying respirator with organic vapor cartridges or 

canister may be permissible under certain circumstances where airborne 

concentrations are or may be expected to exceed exposure limits or for odor or 

irritation. Protection provided by air-purifying respirators is limited. Refer to OSHA 

29 CFR 1910.134, ANSI Z88.2-1992, NIOSH Respirator Decision Logic, and the 

manufacturer for additional guidance on respiratory protection selection. Use a 

NIOSH/ MSHA-approved positive-pressure supplied-air respirator if there is a 

potential for uncontrolled release, exposure levels are not known, in oxygendeficient atmospheres, or any other circumstance where an air-purifying respirator 

may not provide adequate protection. 

Work / Hygiene practices : Emergency eye wash capability should be available in the near proximity to 

operations presenting a potential splash exposure. Use good personal hygiene 

practices. Avoid repeated and/or prolonged skin exposure. Wash hands before 

eating, drinking, smoking, or using toilet facilities. Do not use as a cleaning solvent 

on the skin. Do not use solvents or harsh abrasive skin cleaners for washing this 

product from exposed skin areas. Waterless hand cleaners are effective. 

Promptly remove contaminated clothing and launder before reuse. Use care when 

laundering to prevent the formation of flammable vapors which could ignite via 

washer or dryer. Consider the need to discard contaminated leather shoes and 

gloves.

SECTION 10. STABILITY AND REACTIVITY

Reactivity : Vapors may form explosive mixture with air. Hazardous polymerization does not 

occur. 

Chemical stability 

Possibility of hazardous 

reactions 

 Stable under normal conditions. 

Can react with strong oxidizing agents, peroxides, acids and alkalies. Do not use 

with Viton or Fluorel gaskets or seals. 

Conditions to avoid Avoid high temperatures, open flames, sparks, welding, smoking and other 

ignition sources. Avoid static charge accumulation and discharge (see Section 7).

Hazardous decomposition 

products 

 Ignition and burning can release carbon monoxide, carbon dioxide, noncombusted hydrocarbons (smoke) and, depending on formulation, trace amounts

of sulfur dioxide. Diesel exhaust particals may be a lung hazard (see Section 11). 

SECTION 11. TOXICOLOGICAL INFORMATION

Inhalation 

Skin contact 

: Vapors or mists from this material can irritate the nose, throat, and lungs, and can 

cause signs and symptoms of central nervous system depression, depending on the 

concentration and duration of exposure. 

Skin irritation leading to dermatitis may occur upon prolonged or repeated contact. 

Liquid may be absorbed through the skin in toxic amounts if large areas of skin are 

repeatedly exposed. Long-term, repeated skin contact may cause skin cancer. 

Eye contact Eye irritation may result from contact with liquid, mists, and/or vapors. 

Ingestion 

Target organs 

 Harmful or fatal if swallowed. Do NOT induce vomiting. This material can irritate the 

mouth, throat, stomach, and cause nausea, vomiting, diarrhea and restlessness 

Aspiration hazard if liquid is inhaled into lungs, particularly from vomiting after 

ingestion. Aspiration may result in chemical pneumonia, severe lung damage, 

respiratory failure and even death. 

Central nervous system, Eyes, Skin, Kidney, Liver 

Further information Studies have shown that similar products produce skin cancer or skin tumors in 

laboratory animals following repeated applications without washing or removal. The 

significance of this finding to human exposure has not been determined. Other 

studies with active skin carcinogens have shown that washing the animal's skin with 

soap and water between applications reduced tumor formation. 

Repeated over-exposure may cause liver and kidney injury 

IARC classifies whole diesel fuel exhaust particulates as carcinogenic to humans 

(Group 1). NIOSH regards whole diesel fuel exhaust particulates as a potential 

cause of occupational lung cancer based on animal studies and limited evidence in 

humans.
