1.0 ABSTRACT

This item describes the requirements for the contractor to provide a cold weather plan which documents the planning and actions to be taken by the contractor to prevent damage to the vessel or injury to crew members in the event of significant cold weather. Applicable only to geographic areas where temperatures may drop below 32°F for periods greater than 24 hours.

3.1 Location: Contractor’s facility

4.0 GOVERNMENT FURNISHED EQUIPMENT/MATERIAL/SERVICES: None

5.0 NOTES

5.1 In order to ensure against cold weather damage to the vessel in extreme circumstances, the contractor's cold weather plan may contain References to ballasting and deballasting the vessel. In such an instance the safety requirements of Reference 2.1 shall not be exceeded. Minimum draft clearance shall be two feet beneath the keel at mean lower low water (MLLW).

5.2 The contractor shall not be permitted to alter the ballast conditions of the vessel in any manner without having first submitted detailed Trim and Stability calculations to the <<Administrative Contracting Officer (ACO) or Operating Company Representative (OPCOREP)>>, and having obtained written approval of same from the Ship's Master and the OMT REP.

6.0 QUALITY ASSURANCE REQUIREMENTS: None additional

7.0 STATEMENT OF WORK REQUIRED

7.1 Arrangements/Outfitting

7.1.1 The contractor shall provide a cold weather plan if the facility is located in a geographic location where temperatures are likely to drop below 32°F for periods in excess of 24 hours. The plan shall include a description of the cold weather precautions and protection arrangements available and the preventive measures that will be taken to ensure the safety of the vessel, prevent damage to the ship and protect ship's force from injury during cold weather. The cold weather plan should at a minimum address the following:

a. Daily monitoring and tracking operations of cold weather conditions reported by the National Weather Service (NWS)

b. Maintenance of communications with the local offices of the NWS and Federal Emergency Management Agency (FEMA)

c. A timetable for making decisions including identification of the parties participating in the decision-making process.

d. A timetable for initiating contractor actions relative to; changing weather conditions as the cold weather season approaches, unusual cold spells for the geographic location of the contractor's facility, and winter precipitation patterns for snow, sleet and ice conditions.

e. Personnel resources to accomplish each level of plan actions.

f. Protection and precautions taken to prevent; facility power loss, damage to plant, equipment and services, personnel injury.

g. Protection and precautions taken to prevent access/travel restrictions inside the facility.

h. Actions taken to protect contractor material at outside storage areas.

i. Resources available for snow removal.

j. Resources available to maintain a heating supply for shops, warehouses, offices, etc. in the event of plant power loss.

k. Resources available for continued contractor's communications with the appropriate decision-making company officials.

l. Resources available for continued contractor's communications with OMT REP and the ship's Master.

m. Provisions for adequate lighting inside the contractor's facilities, all walkways to the ship, overhaul management team's office, and parking lots. Lighting illumination hours for normal circumstances and during inclement weather, i.e., rain and/or snowstorms.

7.1.2 Describe the actions the contractor shall plan for and execute for each increased level of protection and precautions in preparation to protect the vessel and ship's force due to the approaching cold weather season, unusual cold spells for the geographic location of the contractor's facility, and winter precipitation patterns for snow, sleet and ice conditions including:

a. Snow and ice removal from weather decks, ladders, gangways, superstructure, and masts.

b. Vessel equipment protection and precautions.

c. Precautions taken if the vessel is on dry dock.

d. Trim and stability calculations for ballasting/deballasting.

e. Interim milestones for notification of OMT REP and ship's Master at each appropriate time of the decision-making process.

f. Level of ship's force participation (if any) for each required action.

g. Covering and removal of the ship's smokestack(s).

h. Draining and maintenance of a dry condition for all pipelines, including fixtures, traps and internal tanks, throughout the ship to avoid freeze damage.

i. Record keeping and monitoring of removed pipe drainage plugs.

j. Installation of system bleed lines or recirculating lines on all temporary water, steam and air hoses/pipes to prevent freeze damage and maintain the systems in service.

k. If it is not be practical to keep the pipelines/systems or fixtures drained; explain how the ship shall be kept heated to a minimum temperature capable of preventing overnight freeze damage. Prepare and submit calculations giving the types, sizes and number of temporary heaters which might be installed in all spaces to provide the heat. The calculations for each compartment should demonstrate the quantities of heaters given are adequate to maintain each space no less than 40° Fahrenheit with the ventilation system secured.

l. Should the ship’s heating system be interrupted by any other work item of the work package; prepare and submit calculations giving the size and number of temporary heaters to be installed in all spaces for general heating. The calculations for each compartment shall demonstrate the quantity of heaters given are adequate to maintain each space no less than 60° Fahrenheit with the ventilation system secured.

m. Freeze protection shall be provided for all tanks and their associated piping systems without regard to the contractor being required to work in these tanks by a work item.

7.0 Freeze protection in tanks shall be by a positive action means of preventing tank bulkhead or piping ruptures.

7.0 The protection may be provided by deballasting and/or pumping of water tanks, opening manhole covers and inserting discharging air lines to continuously give a bubbling action, etc.

n. How deck drains will be kept clear, and in proper working condition open to drain. Actions to clear clogged and blocked drains.

o. Provisions for adequate lighting aboard the ship on all deck levels during inclement weather, i.e., rain and/or snowstorms.

7.1.3 Describe the planning and execution of actions to prevent and protect from weather impact upon the production schedule. Provide local data for the following during the past three years:

a. Normally expected number of rainfall days.

b. Normally expected amount of rainfall (in inches).

c. Normally expected number of snow/sleet fall days.

d. Normally expected amount of snow/sleet fall (in inches).

e. Normally expected number of days with temperatures below freezing.

f. Normally expected periods with temperatures below freezing in quantity and durations in days.

g. Normally expected water temperatures in degrees Fahrenheit.

h. Normally expected wind speeds.

i. Normally expected number of days when the wind speeds exceed this figure.

7.1.4 The contractor is responsible for the costs associated with the planning aspects of the cold weather plan that deal with the safety and protection of the contractor’s facility and the Government’s assets located in that facility. Extraordinary measures required to protect the vessel and its crew shall be presented to the OMT REP as a milestone event in the subject cold weather plan. The OMT REP shall approve these extraordinary measures to prepare for cold weather conditions via a change order.

7.1.5 Extraordinary measures may include such actions as ballasting the vessel, dealing with significant deep freeze and/or exceptionally heavy snow or ice events.

7.1.6 Non-extraordinary protective measures considered to be the responsibility of the contractor include such actions as adding additional mooring lines, temporarily disconnecting ship services, snow and ice removal, freeze protection on and in the vessel.
