Oshima Shipbuilding Co., Ltd. has acquired Approval in Principle (AiP*1) for Multiple Alternative Fuels Ready (Ammonia/ Methanol/LNG) and OCCS*2 Ready from Nippon Kaiji Kyokai (ClassNK).

Due to the uncertainty surrounding next-generation fuels, it is currently difficult to select a single solution among several GHG reduction technologies. Therefore, we have developed a conceptual design for a Multi Ready vessel that can comprehensively be adapted to the retrofit of four types of GHG reduction technologies such as LNG, ammonia, methanol propulsion, and OCCS.

Through the review for the AiP, the feasibility of this vessel has been confirmed from regulatory and safety perspectives.

Oshima Shipbuilding is dedicated to contributing to a sustainable future for maritime transport. We actively support the decarbonization of shipping through our advanced technological expertise.

*1 Approval in Principle (AiP):
At the initial stage of designing or before the specific target ship to be implemented is decided, the design is examined based on the existing regulations such as international conventions and ship classification rules, and an Approval in Principle (AiP) is issued as proof of conformity with requirements. It also prevents rework of regulatory aspects in the post-process, shortens the examination time at the time of class registration, and can be used as a technical basis for external appeal of the design status.

*2 OCCS (Onboard Carbon Capture & Storage system)
