The scope of the standard includes functions, systems and equipment considered important to the safety of the vessel, personnel and the environment. Winterization is primarily focused on the adverse effects and control of snow, freezing, sea spray and atmospheric icing on board the vessel, as well as material properties in cold temperature. Winterization measures include:

— protecting the vessel's functions, systems and equipment considered important to safety,

— provisioning suitable equipment and supplies, and

— implementing procedures for safe operation and personnel welfare.

This standard does not address those hull and machinery requirements necessary for safe navigation through sea ice, which are addressed in the relevant ice-class standards.
