Preparation Prior to Entry in Polar Waters
Vessel machinery should be constructed from suitable materials for low temperatures to ensure proper functionality in the polar environment. This should also include coatings, paint layers and suitable lubricants to ensure the machinery remains protected to the highest degree possible during the voyage.
Operational Considerations
The vessel should be made ready for polar waters by ensuring sufficient positive stability to allow for some decrease caused by icing. The deck should also be made ready by covering manifolds and exposed valves and machinery and gritting or preparing the deck for hazardous ice.
Firefighting and other fire protection systems should already be in locations that prevent freezing or provide suitable heating appliances. If this is the case, these heating systems should be well-maintained and operational before entering polar waters. More information on firefighting systems can be found in Chapter 10 of Resolution A.1024(26).
In the engine spaces, the ambient and machinery temperatures should be monitored to ensure that the cold does not harm the equipment's operation. Heating for the lubricating oil, air intakes, hydraulic oil, and fuel oil systems should all be checked for operation before getting to the polar environment and rectified defects immediately.

Other Important Checks Before Entering Polar Waters
Other precautions which may be taken are:
Draining the freshwater lines on deck.
Draining the fire main.
Checking the anchor wash valves are open and drained.
Greasing and lubricating all exposed machinery.
Purging airlines and checking for condensation.
Testing the lifeboat falls and ensuring that the lifeboats are ready for polar environments.
Checking and maintaining the emergency generator and ensuring all heating systems are available.
