MODUK DEF STAN 02-320 PDF

This Defence Standard specifies the general requirements for the design and installation of fuel systems for Gas Turbine (GT) and Diesel engines and diesel engines in HM Surface Ships, Craft and Nuclear Submarines from the deck filling connections to the inlet connection of the equipment consuming the fuel.

This Standard covers the requirements for the types of fuel to be handled, environmental conditions, materials, drawings and the complete fuel system which may be divided into four sub-systems: 

Tanks; 

Pipework, Valves and instrumentation; 

Fuel Transfer and Primary Clean-up; 

Fuel Delivery and Final Clean.

Note These sub-systems represent the way a practical fuel system is installed in a ship. Each subsystem may be installed by separate designers and/or manufacturers. At the penalty of some repetition each sub-system has its relevant criteria detailed to allow the user of this standard to look at the complete picture without constant cross-referencing on common areas.

Fuel systems and their associated components shall comply with the requirements of all relevant standards whether European, International, National, Military or Naval.

The system designers and component manufacturers shall describe any hazard that may exist during the operation or maintenance of the system. Precautions necessary to remove the hazard shall be detailed. If a hazard cannot be completely eliminated the designer and manufacturer shall state the possible consequences to personnel and equipment.
