Electronic equipment and eto jobs
Heating elements in electronic equipment are to be kept on when the equipment is not in use. Electronic equipment and eto jobs not fitted with heaters is to be left running.
Decks are to be kept as ice free as possible to reduce slipping hazards. Rock salt and sand must be used to help achieve this.
BUNKERS AND WATER
Masters and Chief Engineers must ensure that there are adequate reserves of fuel and water aboard when operating in freezing weather conditions. Increased demand on boilers, heating and possibly steaming out sea chests and piping will cause an increase in consumption of both fuel and water.
All fuel oil tanks are to be kept fully heated at all times.
PRECAUTIONS INSIDE MACHINERY SPACES
Temperatures in machinery spaces should be maintained at a reasonable level by adjusting ventilation and using space heaters where they are provided.
FLOODING DUE TO PIPE BURST
Vessel’s personnel must be alert to the possibility of, and check for, flooding in remote areas such as shaft tunnels and void spaces due to pipes which have burst following freezing. This is particularly important when temperatures rise and any ice begins to thaw.
DOUBLE BOTTOMS AND PEAK TANKS
When the sea water temperature fails below 2°C all tanks which contain fresh water adjacent to the ship’s hull must be kept slack to prevent possible rupturing caused by freezing.
In storerooms and linen lockers or other places where there is a possibility of sweating and freezing, space heaters should be used if they are provided. Moisture absorbing material should be moved to warmer places when possible or moved away from the ship’s structure where moisture collects and freezes.
