TECHNICAL REQUIREMENTS

FOR A

RESEARCH VESSEL WITH ICEBREAKING CAPABILITY

FOR

United States ANTARCTIC Program

## **INTRODUCTION**

### **1.1 Purpose.**  {#purpose. .unnumbered}

These requirements provide a basis for the charter and operation of a
general purpose, multidiscipline oceanographic research Vessel with
icebreaking capabilities. It is the intent that the Contractor shall
deliver and operate this ship complete in all respects for the service
intended. The ship shall be fully equipped and fitted out in accordance
with the best commercial marine practice.

### **1.2 Area of Operation.**  {#area-of-operation. .unnumbered}

The primary mission area of the ship is the Antarctic. The ship is also
expected to make periodic open ocean transits through, and carry out
scientific missions in equatorial waters.

### **1.3 Concept of Operation.**  {#concept-of-operation. .unnumbered}

As with many oceanographic research vessels, this ship shall be capable
of independent operation for endurance periods as identified in the
Technical Requirements. The principal base of operation shall be in the
southern latitudes to minimize transit time to the primary mission
areas. The ship shall operate from such ports as Punta Arenas, Chile or
Ushuaia, Argentina for operation in the Antarctic Peninsula including
Palmer Station and the Weddell Sea. The ship shall also operate out of
such ports as Hobart, Australia or Port Lyttelton, New Zealand for trips
to the Ross Sea and other parts of the Antarctic. Because most logistics
bases are remote from the ship operating area, reliability and
maintainability of equipment are of prime importance. All systems shall
use up-to-date and proven equipment and material.

### **1.4 Relationship Between NSF and The Charterer.**  {#relationship-between-nsf-and-the-charterer. .unnumbered}

The Charterer is responsible for the operation and maintenance of the
United States facilities in Antarctica. One of the tasks that the
Charterer performs is management of research vessels operated by
subcontractors. In this regard, the Charterer is now seeking an
organization to provide and operate a research vessel with icebreaking
capabilities.

### 1.5 **Representative Mission Profile.**  {#representative-mission-profile. .unnumbered}

A notional annual operating profile for the ship is shown below:

  ---------------------- --------- --------- --------- ---------------------

This annual profile is provided for illustrative purposes only, and is
not contractually binding. It is not intended to restrict operation of
the ship in any way. See Sample Charter, Special Conditions Clause 24,
Employment, Paragraph (c).

### **1.6 Ship Size Estimate.**  {#ship-size-estimate. .unnumbered}

The length overall (LOA) shall be less than 320 feet to facilitate
turning in the tight passages and basins where the ship shall operate.
The draft of the ship shall not exceed 30 ft, as this would preclude
entry into Arthur Harbor at Palmer Station. There are no beam or
displacement limitations on the ship.

### **1.7 Ship Trials.**  {#ship-trials. .unnumbered}

The ship shall be subject to dock and underway trials to show that all
technical requirements have been satisfactorily filled prior to
Charterer's acceptance of the Vessel and commencement of the Charter. A
schedule of trials, including procedures and data to be taken, shall be
provided to the Charterer for approval no later than three months after
contract award. The trials will be witnessed by under the supervision of
Charterer personnel and their representatives.

## **ENVIRONMENTAL REQUIREMENTS**

### **2.1 Ice Conditions.**  {#ice-conditions. .unnumbered}

The ship shall operate in annual ice from the ice edge up to and
including the consolidated pack and fast ice. The ship is expected to
routinely operate in partial coverage of first-year ice floes that could
contain some glacial ice. Level icebreaking and ramming capability in
annual ice shall be required and is specified in Section 3.1,
Icebreaking Capability.

### **2.2 Sea State.**  {#sea-state. .unnumbered}

Data on sea states in the primary area of operation are shown below.
Ship performance in those sea states is specified in Section 3,
Operational Performance Requirements.

  -------------- -------------- -------------- -------------- --------------

  6              18             16             38             12.0

  7              4              25             52             15.0
  -------------- -------------- -------------- -------------- --------------

### **2.3 Air Temperature.**  {#air-temperature. .unnumbered}

The ship can be expected to encounter very cold temperatures during the
Antarctic winter. The ship shall be capable of operating in a minimum
expected winter air temperature of -50 degrees F. Average winter air
temperatures in the -10 to -20 degree F range are expected. Even at
milder temperatures, a wind-chill index of -50 degrees F and lower can
be expected to continue for days. Air temperatures in open water during
the winter season could be as low as 10 degrees F, and with sea spray
could lead to rapid deck and superstructure icing. The ship shall be
capable of operation in a maximum air temperature of 120 degrees F since
the ship may perform scientific and logistics missions in equatorial and
tropical zones.

### **2.4 Wind Velocity.**  {#wind-velocity. .unnumbered}

The ship shall be capable of enduring a maximum sustained wind speed of
100 kt.

### **2.5 Sea Water Temperature.**  {#sea-water-temperature. .unnumbered}

Sea water temperatures can be expected to range from a high of 90
degrees F to a low of 28 degrees F. The ship shall be capable of
operation in this range of water temperatures.

### **2.6 Precipitation.**  {#precipitation. .unnumbered}

Precipitation in the form of rain, freezing rain, sleet, and snow can be
expected. The ship layout and equipment shall consider all of these
conditions with the intent of minimizing accumulation aboard the ship,
minimizing the potential adverse effect on ship operations, and
providing for removal.

### **2.7 Fog and Reduced Visibility.**  {#fog-and-reduced-visibility. .unnumbered}

Reduced visibility shall occur during ship operations. The ship shall
have the navigational capability to operate in a safe manner during fog
and reduced visibility conditions.

### **2.8 Topside Icing.**  {#topside-icing. .unnumbered}

Severe topside icing shall occur at times due to the combination of cold
seawater and air temperatures with high sea states in the primary
operating area. Spray icing rates of 1/2 inch per hour can be expected
in extreme events. The extreme icing event has been estimated to be a
24-hour exposure at this icing rate. This extreme event results in the
following ice accumulations and loads on the main deck forward of the
superstructure.

+-----------------------+-----------------------+-----------------------+
| Accumulation          | Location              | Load                  |
|                       |                       |                       |
| (inches)              |                       | (lb/sq ft)            |
+-----------------------+-----------------------+-----------------------+
| 12.0                  | Horizontal Surfaces   | 43.6                  |
+-----------------------+-----------------------+-----------------------+
| 9.6                   | Vertical Surfaces     | 34.8                  |
+-----------------------+-----------------------+-----------------------+
| 10.8                  | Exposed Gear          | 39.4                  |
+-----------------------+-----------------------+-----------------------+
| 10.8 Radius           | Rigging and Stays     | 111.1 lb/ft           |
+-----------------------+-----------------------+-----------------------+

These loads shall be reduced linearly with height such that all loads
are zero at 100 ft above the Design Waterline (DWL). Icing is assumed
not to occur on the shell plating or area below the main deck (uppermost
watertight deck). Icing loads shall also be reduced linearly with
distance aft along the ship. Icing loads shall be constant with length
over the foredeck and start to reduce aft of the forward end of the
superstructure, resulting in zero load at the stern of the Vessel. The
ship shall be capable of surviving such an icing event.. Given the
severity of the icing loads, the ship shall have clean decks and
superstructure, free of all but essential fittings and equipment, to
minimize ice accretion. In addition, the aft and starboard side working
deck shall be fitted with a heating system to keep the decks free of ice
and snow accumulation.

## **OPERATIONAL PERFORMANCE REQUIREMENTS**

### **3.1 Icebreaking Capability.**  {#icebreaking-capability. .unnumbered}

The ship shall be able to operate through first-year ice conditions of:

Level ice thickness 3 ft at 3 kt

\- compressive 575 psi

The ship shall also be able to encounter and transit pressure ridges of
at least 6-ft sail height (corresponding to a keel depth of 20 ft) in
the ramming mode of operation. In addition to ramming pressure ridges,
the ship shall periodically be expected to back and ram through level
ice of 6-ft thickness in order to get to a desired science station.

### **3.2 Heeling and Trimming.**  {#heeling-and-trimming. .unnumbered}

A heeling system shall be installed in the ship capable of rolling the
ship in ice by rapidly transferring water or fuel from one side of the
ship to the other. The heeling system shall be capable of rolling the
ship from 5 degrees port list to 5 degrees starboard list and back again
in 2 minutes in open water. The ship shall also have sufficient ballast
tankage in the ends of the ship to change her trim by 3 ft both by the
bow and by the stern.

### **3.3 Open Water Powering.**  {#open-water-powering. .unnumbered}

The ship shall be able to maintain speed as given in the table below at
any heading relative to the prevailing wind and waves

  ----------------------- ----------------------- -----------------------

### **3.4 Seakeeping.**  {#seakeeping. .unnumbered}

The ship shall be able to maintain ship motions that do not exceed the
values given below in sea state 6 (16 ft significant wave height) and
short-crested seas (cosine squared spreading function) as described in
Section 3.4 on any heading at speeds up to 8 kt. For the purposes of
determining motions, the wind is collinear with the seas and a steady
current of 2 knots is at 45 degrees to the wind and seas.

> hour

### **3.5 Stationkeeping.**  {#stationkeeping. .unnumbered}

The ship shall be able to maneuver and keep station within a 300 ft
diameter circle or 3 percent of the water depth, whichever is greater,
in seas up to 12 ft significant wave height, 10 second average modal
period, mean winds of 30 kt, and 2 kt of steady current. The wind and
waves directions are collinear and the current direction is at 45
degrees to them. Ship heading can be selected to give best
stationkeeping ability. A dynamic positioning system to control the
propulsion and maneuvering systems to meet this criterion is specified
in Section 5.8

### **3.6 Track Keeping.**  {#track-keeping. .unnumbered}

The ship shall be capable of remaining within 500 ft or 5 percent of the
water depth, whichever is greater, of any specified straight trackline
and shall be capable of maintaining its heading within ±15 degrees of
its mean heading for all forward speeds between 1 and 6 knots. These
tolerances shall be maintained in Sea State 5 or lower, with
long-crested seas, as described in Section 5.8. The wind and waves are
collinear and have an arbitrary heading relative to the trackline and
there is a 2-kt steady current at 45 degrees from the wind/wave
direction. A dynamic positioning system to control the propulsion and
maneuvering systems to meet this criterion is specified in Section 5.8

### **3.7 Night Operation.**  {#night-operation. .unnumbered}

Ship operations are based on year-round science. Long periods of
darkness can be anticipated during the winter months due to the extreme
latitudes of operation. The ship shall provide adequate lighting, both
interior to the ship and exterior, in accordance with the Illuminating
Engineering Society Publication RP‑12, "Recommended Practice for Marine
Lighting". In addition, science related lighting installations are
required, including but not limited to:

Floodlights that illuminate the sea or ice surface outboard of all main
weather decks and especially where science packages, personnel, or cargo
may be lowered over-the-side.

Flood lighting that also illuminate the area outboard of the ship
forward of the bridge where ice piece turn up as the ship breaks ice.

At least four large searchlights for night ice navigation.

### **3.8 Intact Stability.**  {#intact-stability. .unnumbered}

Intact stability requirements shall be determined in accordance with US
Coast Guard Subchapter U including the lifting of heavy objects from the
various cranes. In addition, the ship shall be able to sustain a 100 kt
beam wind heeling moment and an 80 kt beam wind heeling moment with the
icing described in Section 2.8. The following criteria for adequate
stability under severe wind and rolling conditions (weather criterion)
shall be demonstrated for each standard condition of loading given in
Subchapter U, with and without the icing load and with reference to
Figure 1, as follows:

The ship is subjected to a steady wind pressure acting perpendicular to
the ship\'s centerline, which results in a steady wind heeling lever,
l~w~ , varying with heel angle as a cosine squared function of heel
angle:

l~w~ = l~wo~ cos^2^ θ (1)

where l~wo~ is the wind heeling lever for the ship in the upright
position. The heeling arm for an upright position is given by the
following formula:

l~wo~ = Σ (p A z)/(2240 ∆) (2)

where: ∆ = displacement of the ship (LT)

A = projected lateral area of a part of the ship above the waterline

z = vertical distance from the center of A to the center of the
underwater lateral area (approximated as a point at one-half the draught
if the center is not known)

p = wind pressure (psf) exerted on A as function of height above the
waterline:

p = 0.103 v^2^ (3)

where v is in kt and is scaled based on a reference wind speed, v~o~ ,
the height z, and the height at which the reference wind is measured,
z~o~ ; for these purposes a 32.8 ft height is assumed.

v/v~o~ = 1 + c ln \[(z + z~1~ )/(z~o~ + z~2~)\] (4)

with: c = 0.099754,

z~1~ = -- 0.02961 z~o,~

z~2~ = 0.053621 z~o~

> From the resultant angle of equilibrium, θ~ο~ , the ship is assumed to
> roll due to wave action to an angle of roll, θ~r~ , to windward. The
> roll amplitude, θ~r~ , shall be taken as 25^o^ or determined from
> model tests.

![](media/image1.wmf)

Figure 1. The intact stability weather criterion.

> The wind heeling arm curve shall be for a wind velocity of at least
> 100 knots without an icing load and 80 kt with an icing load. For each
> condition of loading, the following criteria shall be met:
>
> The heeling arm at the angle of equilibrium, θ~o~ , shall not be
> greater than 0.6 of the maximum righting arm.
>
> The area A~1~ shall be not less than 1.4 of area A~2~.

### **3.9 Compartmentation and Limiting Drafts.**  {#compartmentation-and-limiting-drafts. .unnumbered}

Compartmentation and limiting draft requirements shall be determined in
accordance with US Coast Guard Subchapter U.

### **3.10 Damaged Stability** {#damaged-stability .unnumbered}

> Damaged stability requirements shall be determined in accordance with
