International Code of Safety for Ships Using Gases or Other Low Flashpoint Fuels (IGF Code) Updates

Regulation 6.7.1.1 of the IGF Code was amended to remove “tank cofferdams” as spaces requiring a pressure relief system to correct inconsistencies between the IGF Code and IGC Code. Tank cofferdams must be kept gastight and appropriately ventilated. A comparable paragraph in the IGC Code does not include tank cofferdams in the requirements for pressure relief systems. In paragraph 11.3.3 of the IGC Code, cofferdams for fire protection are not expected to be subject to leaks from fuel containment systems because LNG fuel pipes are routed through such spaces and protected by a secondary enclosure, as required by paragraph 9.5.1 of the IGF Code. 

Effective Date: January 1, 2024

A new Regulation 11.8 was added to the IGF Code to enhance safety in fuel preparation rooms containing pumps, compressors, or other potential ignition sources by requiring the installation of a fixed fire extinguishing system. Such systems must also comply with Regulation 10.4.1.1 of SOLAS Chapter II 2. 

Effective Date: January 1, 2024

A minor amendment was made to the requirements for welding procedure tests for cargo tanks and process pressure vessels to broaden the scope of requirements for cross weld tensile strength. Previously worded to apply to “aluminum alloys,” the requirement will now be more broadly applicable to “materials such as aluminum alloys.” The amendment is intended to clarify the broader application of tensile tests to metallic materials rather than just aluminum.
