All machinery, electrical equipment, boilers and other pressure vessels, associated piping systems, fittings and wiring shall be of a design and construction adequate for the service for which they are intended and shall be so installed and protected as to reduce to a minimum any danger to the crew, due regard being paid to moving parts, hot surfaces and other hazards. The design shall have regard to materials used in construction, and to marine and industrial purposes for which the equipment is intended, the working conditions and the environmental conditions to which it will be subjected. Consideration shall be given to the consequence of the failure of the system and equipment essential to the safety of the installation/unit.

Machinery and equipment, which is not fully covered by these Rules, must comply with recognized codes and standards and may be required to undergo tests and trials.

In addition to the requirements contained in these Rules, GL reserve the right to impose further requirements in respect of all types of machinery and equipment where this is necessitated by new findings or operational experience. GL may permit deviations from these Rules so far the general safety standards are equivalently fulfilled. A.5 National Rules or regulations remain unaffected.
