machinery

CHAPTER SUMMARY
Chapter 6 identifies requirements for ensuring that the machinery installations used on board ships operating in Polar Regions are capable of functioning under low temperatures and anticipated environmental conditions. These are clearly set out in the Chapter 6 wording below, and in the Part 1B Additional Guidance.

watertight and weathertight

CHAPTER SUMMARY
Chapter 5 contains requirements to maintain the watertight and weathertight integrity of all closing appliances and doors on board a ship, including measures to remove or prevent ice accretion, prevention of freezing or excessive viscocity of operating liquids. The requirements also take into account in design that crew personnel operating closing appliances and doors will be wearing heavy wintered clothing, including thick mittens. These are clearly set out in the Chapter 5 wording below.

ship structure

CHAPTER SUMMARY
Chapter 3 includes provisions to ensure that the material and scantlings of ships with or without ice strengthening retain their structural integrity under certain environmental loads and conditions. This chapter seeks to provide assurance that a ship’s structure is suitable for the environmental conditions (e.g. ice loads and temperature) by requiring that a ship’s design plan be made to a recognized standard, such as the Polar Class or the Finnish-Swedish (Baltic) classes, and that materials be suitable if the vessel operate at low temperatures. These are clearly set out in the Chapter 3 wording below, and in the Part 1B Additional Guidance.

pwom

CHAPTER SUMMARY
Chapter 2 describes content to be included in the Polar Water Operational Manual (PWOM), a mandatory ship-specific document designed to support decision making through the identification of procedures for operations under routine and emergency conditions. The PWOM must contain references to methodologies used to determine capabilities and limitations of a vessel in ice. The Regulations require that vessels develop and carry a PWOM on board, and require that a variety of risk-based procedures are to be taken into consideration. These are clearly set out in the Chapter 2 wording below, and in the Part 1B Additional Guidance.
