This International Standard specifies the content, type, design, layout and usage of shipboard and marine installation plans to be available and displayed for fire control appliances and arrangements, damage control, life-saving appliances and arrangements, and means of escape. It also specifies graphical symbols and illustrations used in such plans.

This International Standard is not intended to cover escape plans used as signs and mimics signs for general safety information.

This revision of the ISO 17631 includes the IMO amendments to the IMO MSC.1/Circ.1245 Guidelines for damage control plans and information to the master and MSC.1/Circ.1570 Amendments to section 3 of the guidelines for damage control plans and information to the master.

This international standard applies to a positive displacement pump (hereinafter "pump") and its auxiliary devices for marine LNG fuel gas supply system (FGSS). This standard specifies test procedures and requirements for the performance test that shall be conducted in order to confirm the mechanical features of the pump and its auxiliary devices.

Note As a principle, LNG should be used as the medium to verify the performance of the pump. However, it may not be practical to carry out the tests with LNG prior to installation. Hence, a medium other than LNG, such as liquefied nitrogen or other fluid colder than LNG, may be used in order to conduct the test as a reference to the performance of the pump.

This international standard specifies the evaluation methods of characteristics such as pressure, flow rate, temperature and system stability of Fuel Gas Supply Systems (FGSS), which are manufactured to use vaporized LNG or boil-off gas as fuel gas supply to the vessel's gas consumers. The main purpose of this standard is to evaluate the performance of the LNG FGSS: (1) prior to delivery or installation on board a ship, and (2) to assure the system characteristics are taken into account for the entire gas consumers during ship’s gas trial or sea trial.

NOTE As a principle, LNG shall be used as medium to verify the performance of the LNG FGSS. However, it may not be practical to carry out the tests with LNG prior to installation on board a ship. Hence, medium other than LNG, such as liquefied nitrogen or other fluid colder than liquefied temperature of LNG, may be used in order to conduct the test as a reference to the performance of LNG FGSS.
