Scope and Application

This Guide is for optional application to ship types other than those falling under the scope of the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) and the ABS requirements under Part 5C, Chapter 8 of the ABS Rules for Building and Classing Marine Vessels (Marine Vessel Rules) and burning their cargo. It is applied to vessels burning conventional fuels but having design features suitable to permit conversion at a future date to a particular gas burning concept based on existing Class requirements for gas fueled ships.

The requirements for the design and construction of all features of systems proposed are established in the Part 5C, Chapter 13 of the ABS Rules for Building and Classing Marine Vessels (Marine Vessel Rules).

It is recognized that at the time of the conversion of a vessel to LNG fueled, the arrangements and installations will still be subject to approval by the flag Administrations and the flag Administration may implement the IMO requirements in effect at the time of conversion.

This Guide is to be applied to both new construction and existing vessel conversions, regardless of size, utilizing natural gas as fuel.
