7B Machinery - Vessels of 500GT and Over

Objective:- This section outlines the minimum requirements for machinery, which are to be in accordance with the requirements of one of the Classification Societies defined in the National Annex. The Class Notation should cover the minimum aspects defined within this chapter even if the machinery is not considered the primary means of propulsion.

  7B.1 For existing and new vessels the machinery and its installation should meet the standards of one of the Classification Societies and of SOLAS Chapters II-1/Part C Machinery installations and II-1/Part E - Additional requirements for periodically unattended machinery spaces, so far as is reasonable and practicable to do so.

  7B.2 In any case the intention should be to achieve a standard of safety which is at least equivalent to the standard of SOLAS. Equivalence may be achieved by incorporating increased requirements to balance deficiencies and thereby achieve the required overall standard.

  7B.3 Where gas turbines are to be fitted, attention should be paid to the guidance contained within the IMO High-speed Craft Code, and installation is to be to the satisfaction of the Administration.
