Chapter 8 – Auxiliary Machinery Systems

Parent topic: Part A – Construction Provisions

8.1 General

  8.1.1 Equipment and systems should be designed so that personnel exposure to cold temperatures and other environmental hazards during normal operations including routine maintenance is minimized.

  8.1.2 Ventilation systems should provide sufficient air for the operation of auxiliary machinery, air conditioning and heating purposes.

8.2 Materials

  8.2.1 Materials used in equipment and systems should be suitable for operation in the environment which prevails at their location. In particular, equipment or systems which are essential for preventing pollution or for safe operation of the ship when:

  • .1 located outside and above the waterline in any ship operating condition; or

  • .2 in unheated locations inside,

 should not be susceptible to brittle fracture within the range of operating conditions.

  8.2.2 Essential equipment or systems required for the safe operation of the ship or systems required for preventing pollution, located within spaces which, upon failure of the primary heating system, could be subject to outside ambient air temperatures should be:

  • .1 provided with an independent source of heat; and

  • .2 fabricated from materials that will not be susceptible to brittle fracture under the anticipated loads and temperatures.

  8.2.3 For Polar Class ships which may be laid up in polar waters, materials for all systems with the potential to pollute should be suitable for preventing pollution at the lowest ambient temperatures to which they may be subjected and should be suitable for avoiding pollution and ensuring safe operation on re-activation of the systems.
