ClassNK has awarded an Approval in Principle (AiP) to Mitsui E&S Shipbuilding Co., Ltd. for their methanol fuel delivery system, recognizing its potential in decarbonization efforts. Methanol is seen as a promising alternative fuel, with green options like biomethanol and e-methanol showing potential for reducing greenhouse gas emissions. However, methanol’s toxicity and flammability require strict safety measures, prompting the IMO to establish guidelines for its use as fuel.

The IMO’s “Interim Guideline for the Safety of Ships Using Methyl/Ethyl Alcohol as Fuel” addresses these concerns and sets safety requirements for methanol use. ClassNK reviewed Mitsui E&S Shipbuilding’s system design based on their guidelines and issued the AiP after confirming compliance with safety standards. Through such evaluations, ClassNK aims to support advanced decarbonization initiatives while ensuring safety in alternative fuel systems.

The AiP serves as evidence of compliance with regulations during the initial design phase, streamlining the approval process and providing a technical basis for future design decisions. By recognizing innovative solutions like Mitsui E&S Shipbuilding’s methanol system, ClassNK continues to contribute to the advancement of sustainable shipping practices and safety assessments.
