The requirements of the Rules for the Winterisation of Ships apply to ships intended to navigate in cold climates and may be exposed to low temperatures that may cause equipment to freeze due to ice accretion from atmospheric icing or sea spray, or due to freezing of liquid within a system. Protection measures are to be provided and operational procedures are to be specified to ensure that equipment is suitably protected to enable operation in low temperatures. 

Compliance with these Rules is optional, and the requirements are additional to those applicable in other Parts and Chapters of the Rules and Regulations for the Classification of Ships

Features that are certified on the basis of these Rules are:

  • Hull construction materials
  • Equipment and systems materials
  • Equipment and systems
  • Stability
