	A.	WHEREAS
    PGTM is engaged in the business of marketing and sales of its patented emission control technologies called ENVI-CleanTM
    and ENV1-MarineTM scrubbing systems (the "System") which are capable of removing sulphur
    dioxide and other acid gases from exhaust gas emissions to a level that meets the regulatory requirements of the International
    Maritime Organization (the "IMO”):




 


	B.	WHEREAS
    the System's effective scrubbing of regulated emissions enables ship owners to achieve cost savings by allowing the continued
    use of lower cost heavy fuel oil ("HFO") when operating in Sulphur Emission Control Areas ("SECA").




 


	C.	WHERE
    AS UML WESTMINSTER is the wholly-owned subsidiary of Union.




 


	D.	WHEREAS
    Union intends to purchase the System for up to an additional ten vessels over the following eighteen months subject to
    the Systems performance.




 


	E.	WHEREAS
    PGTM proposes to supply UML WESTMINSTFR with the System for the main engine of the vessel named "Westminster
    ("Candidate Vessel"). The System will operate in accordance with the terms and specifications contained
    herein.




 


	F.	WHEREAS
    UML WESTMINSTER presently desires to acquire an emission control system to: (a) meet the IMO sulphur emission regulations
    within the SECA's in which it operates: (b) to minimize the cost of air emission compliance: and (c) to minimize the operating
    changes within its ship's systems.




  




     


     


    

 





NOW
THEREFORE in consideration of the covenants contained herein, PGTM, Union and UML WESTMINSTER mutually agree as follows:


 


	1. 	DEFINITIONS
    AND INTERPRETATION




 


	1. 	In
    this Heads of Agreement the following terms shall have the following meanings:




 


"Accepted"
means that PGTM and the System have met the IMO's performance standards for vessels operating within a SECA;


 


"Candidate
Vessel" means the vessel nominated by Union to receive the ENVI-MarineTM
scrubbing system. It is agreed that this is the Westminster. Union have the option to substitute the Candidate Vessel for
another vessel on or before 17.00 Hrs BST on the 5th of September 2016 on the same terms as this Agreement at which time UML Westminster
Limited will also be substituted for another Union subsidiary.


 


"Emission
Control Technology" means the integrated technology, techniques and processes proposed to be adopted onboard the Candidate
Vessel for the purpose of achieving the required level of air emissions reduction. The System will be a key component of the emission
control technology;


 


"Energy
Management Lease Agreement" means the definitive agreement in regards to the purchase option finance lease to be entered
into between PGTM and UML WESTMINSTER on substantially the same terms set out in this Heads of Agreement;


 


"Fuel
Cost Savings per Hour" as detailed in Schedule 3 shall mean the difference in cost/tonne of HFO 380 and LSMGO less the average
operating cost/tonne multiplied by the number of tonnes of fuel consumed per day divided by 24 hours to yield the hourly fuel
cost savings.


 


"LSMGO"
means 0.1% sulphur fuel specified by the IMO as the basis for SECA sulphur emission compliance;


 


"Operating
Quarter" shall mean each period of three (3) months commencing from the date on which the System is successfully tested and
is accepted by UML WESTMINSTER;


 


"Open
Mode" shall mean the operating mode where raw seawater is pumped through the System and discharged into the sea with a minimum
of processing. This is considered the standard operating mode for open sea operations. See Schedule 2 for a detailed description.


 


"Closed
Mode" shall mean the operating mode whereby the seawater is recirculated through the scrubber in a closed loop. This mode
would be used for main engines in circumstances where effluent discharge regulations or lack of seawater alkalinity require this
operating mode. See Schedule 2 for a detailed description.

SCHEDULE
1


 


PRINCIPAL
COMPONENTS OF THE ENVI-MARINETM SYSTEM


 


PGTM
proposes to supply and install an ENVI-MarineTM SO2 scrubbing system which is comprised of the
following principal components:


 


Gas
Conditioning Chamber (GCC) — This engine exhaust gas inlet chamber uses seawater or recirculated water spray to quench the
exhaust gas to approximately 35°C.


 


Scrubber
— The scrubber body combines PGTM's patent-pending scrubber head with a volume of packed bed media (PBM) located above the
head. Demisters dry the gas prior to exit to atmosphere. The footprint of the scrubber body is variable depending on the configuration
of space available. In general, the scrubber is to be positioned at deck level corresponding to the base of the external stack
enclosure.


 


Because
the scrubber heads are horizontal, the scrubber can be configured into any shape. The marine scrubbers are to be made from stainless
steel selected for corrosion and acid resistance. To make the best use of space it is planned to make the bodies rectangular in
shape. The footprint required is approximately 1m2 for each MW of main engine propulsion.


 


Dissolved
Air Flotation (DAF) Tank — The DAF tank receives water from the scrubber and subjects it to DAF treatment, whereby soot, light
particulate and oil droplets are separated from the scrubber water by flotation. The oily particulate is then skimmed from the
tank and sent to the Oil Water Separator system. The rest of the water, which may still contain some heavier particulate, is directed
to the Recirculation Tank.


 


Oil
Water Separator (OWS) System — The oily waste skimmed from the DAF tank is mainly comprised of water. The OWS system is designed
to concentrate the oily waste for storage in the Oily Waste Tank, and discharge the clean water. The water may be directed to
the Recirculation Tank during Open Mode operation or to the Effluent Holding Tank during Closed Mode operation.


 


Oily
Waste Tank — The Oily Waste Tank holds the residue from the OWS system for removal at a land based facility.


 


Recirculation
Tank — The Recirculation Tank receives water from various sources and aggregates it for recirculation by pumps to the
GCC water sprayers, the Hydrocyclone System, and the PBM water distributor. The tank is partitioned so that water from the DAF
tank potentially containing heavier particulate is directed to the Hydrocyclone System, and clean water returning from hydrocyclone
treatment is sent back to the scrubber. In Open Mode operation, excess water overflows from the Recirculation Tank to the Effluent
Holding Tank prior to being discharged to sea.


 


Heat
Exchangers — In Closed Mode operation, recirculated scrubber water is cooled using heat exchangers supplied with cold
seawater by the seawater pumps.


 


Hydrocyclone
System - Banks of hydrocyclones are used for heavier solids separation. Each system draws from a section of the partitioned
Recirculation Tank. The underflow containing the particulate is sent to the Disc Centrifuge for further concentration, and the
clean overflow water is sent back to the clean water side of the Recirculation Tank.


 


Disc
Centrifuge — The Disc Centrifuge subjects the underflow from the hydrocyclones to high inertial forces to concentrate
solids to a high degree for storage in the Centrifuge Sludge Tank.


 


Effluent
Holding Tank — When at sea the overflow from the Recirculation Tank is held briefly in the Effluent Holding Tank before being
discharged to the sea. The Effluent Holding Tank is equipped with an Effluent Monitor for analysis of pH, turbidity and phenanthrene
PAH. When in port or when regulations restrict discharge the tank is used to hold the small flow of effluent water from the OWS
system during Closed Mode operation for later discharge at sea.

Caustic
Soda Tank  — Caustic soda is to be stored on deck in a 20-foot ISO tank configured as a 20-foot bulk container. The
tank will act as a reservoir for a small caustic soda surge tank located in the water processing area below decks. Injection
pumps to provide alkalinity to the scrubber water during closed mode or hybrid open mode are installed with the surge
tank.


 


Continuous
Emissions Monitoring System (CEMS)  — The system includes a Continuous Emissions Monitoring System (CEMS) to
monitor and record sulphur dioxide emissions on a continuous basis. Access to this information is required by regulatory
authorities.


 


Effluent
Monitor  — A tamper-proof system to monitor the pH, turbidity and phenanthrene PAH of the effluent will be part
installed on the Effluent Holding Tank discharge line.


 


Programmable
Logic Controller (PLC)  — The system will be controlled by a small programmable logic controller (PLC) with a
graphic user interface at the operations station or control room. The system will normally operate in automatic mode, but
manual control, data logging and trend screens will also be available. Depending on the ship's communication capabilities,
the system could also be monitored and controlled remotely. This would allow the shipping company and/or PGTM staff to
troubleshoot any problems from land-based offices.

DESCRIPTION
OF OPEN AND CLOSED OPERATING MODES


 


Open
Mode Operation


 


In
open operating mode raw seawater is pumped through the scrubber system. This is considered the standard operating mode for most
open sea operations. The seawater is pumped directly to the scrubber water distribution manifolds at the gas conditioning inlet,
and the top of the packed bed media. Scrubber water draining from the packed bed media supplies water to the turbulent scrubbing
zone above the patented scrubbing head.


 


SO2
is removed and neutralized as the exhaust gases pass counter-current through the water flows. The water drains from the scrubber
base to a flotation skimmer tank which uses air and dissolved air flotation to separate unburned carbon and oil from the scrubber
water. This material is skimmed from the flotation skimmer tank and directed to the Oil Water Separation (OWS) system, which concentrates
the oily waste into a sludge and stores it in a sludge tank.


 


The
excess clean water from the OWS system is then combined with the remainder of the water flow from the flotation skimmer tank and
directed to the recirculation tank and then to the effluent holding tank. If high turbidity is an issue, then some of the water
can be processed through the hydrocyclone system and disc centrifuge to reduce the overall levels. The cleaned water from this
operation may be sent to the GC inlet or directly to the effluent storage tank.


 


The
water held in the effluent holding tank is monitored continuously and then combined with reaction water for pH balancing prior
to being released to the sea. In the event that the monitor measures a high reading for pH, turbidity or phenanthrene PAH, the
system will take a series of actions to respond, depending on which parameter is high. High acidity can be remedied by adding
NaOH to the seawater and excess turbidity or phenanthrene PAH can be remedied by operating the hydrocyclone system and disc centrifuge.
If these steps do not solve the problem, the system can be switched to closed mode operation where there is no discharge to the
sea.


 


Closed
Mode Operation


 


In
closed mode operation the seawater is recirculated through the scrubber in a closed loop. This mode is used for auxiliary generators
and boilers while in port, and for main engines in circumstances where regulations require that no effluent can be discharged.
Three aspects of the scrubber's operation are altered in this mode. First, the loss of seawater alkalinity is made up by the addition
of NaOH to the recirculation tank. Second, heat added through the cooling of the exhaust gas is removed by heat exchangers cooled
with raw seawater. Third, the overflow from the flotation skimmer tank, hydrocyclone system and disc centrifuge are returned to
the recirculation tank for recirculation to the scrubber.


 


The
raw seawater used to cool the scrubbing fluid makes a single pass through both the scrubber distribution and GC heat exchangers
before being discharged. This water is not in contact with the engine exhaust gases, so it does not require any treatment.


 


In
closed mode the scrubbing fluid takes the same path through the scrubber but at a reduced flow rate since alkalinity can be made
up by NaOH addition. The closed system requires continuous cleaning so as to not build up oil or solids, so the flotation skimmer
tank, OWS system, hydrocyclone system and disc centrifuge are all fully operational. A certain amount of bleed is necessary to
eliminate dissolved solids, and this is taken from the OWS clean water overflow, which is directed to the effluent storage tank.
As this is treated effluent, it will meet discharge criteria once the vessel is back in the open ocean where discharge is allowed.


 


Oily
sludge is sent to the Oily Waste tank and centrifuge sludge may be sent there as well or to a separate tank. Fresh water is added
to the recirculation tank to make up for water lost to evaporation in the scrubber and effluent sent to storage. NaOH is added
as required to maintain the pH of the scrubber water.
