What is Cold Weather precautions ?

  1. Passage plan to be amended / revised as required.
  2. Safety meeting held, all hod’s notified, masters standing orders revised.
  3. Engines on stand by & man on steering.
  4. Ensure both steering motors are on.
  5. Ensure radars operating continuously & tuned for peak performance.
  6. Communication equipment should be reliable & working at peak performance.
  7. Echo sounder should be running at all times.
  8. Additional look out to be posted & alert lookout kept.
  9. Ensure searchlights on the bridge wings are working properly.
  10. All weather reports to be received & plotted on the relevant chart.
  11. Level of ballast tanks to be reduced to 90% so as to account for water expansion. Ensure stability is good.
  12. Drain all fire lines, fresh water lines, steam lines, tank cleaning heater, deck airlines, I.G. lines, C.O.W lines & cargo lines.
  13. All suction strainers, seperators to be drained & cleaned.
  14. Use antifreeze in the P.V. breaker, ODMCS fresh water tank & ballast tanks.
  15. Apply low temperature grease to all moving parts, wires, lifeboat davits, sheaves, hatch covers & winches.
  16. Use burlap lagging of jute to prevent icing.
  17. Spread rock salt on deck as it may be slippery due to formation of thin ice.
  18. Commence heating for the following:
    • Fwd & aft whistle signals.
    • Fwd & aft hydraulic tanks of mooring winches, v/v’s & pumps.
    • Heater’s in cranes.
    • Steam heating in fuel tanks, cargo tanks & freshwater tanks.
    • Radar scanners.
    • Bridge front windows.
    • Accommodation.
    • Steam winches.
    • Deck seal
    • Lifeboat fuel tank & fresh water.
    • Emergency steering hydraulic header tank.
  19. Ensure proper winter gear available for the crew. The seriousness of frostbites discussed with all personnel.
  20. Ensure steam water inlets have steam heating coils or compressed air blowing pipes.
  21. Avoid any accumulation of seawater on deck.
  22. Portable steam hoses to be rigged & kept handy for external heating.
  23. Ice accumulation can occur on rigging & structures which can effect stability hence the same should be checked regularly. Also personnel to be aware that the accumulation can fall off on deck & so to be careful when working within these areas.
  24. Crew to use catwalk / walkways where ever possible, or else rig deck safety line from fwd to aft on both port & stbd side.
  25. Main sea water recirculation system to be regulated to maintain set values at ~ 250
  26. Enclosed fresh water cooling system to have anti freeze.
  27. Check specification of stern tube l.o, if antifreeze additives required.
  28. Change over sea suction from high to low.
  29. Ensure watch keeping officers have thoroughly read & understood np100 (mariners handbook)-chapter 6 & 7, relevant sailing directions, routing charts.
  30. Master to make a report with the following information on encountering air temperatures below freezing associated with gale force winds causing severe ice accummulation on ships:
    • Air & sea temp
    • Force & direction of the wind
    • Position of the ship
    • Gmt & date of observation
