ClassNK granted the Approval in Principle (AiP) for the world’s first concept design of the methane oxidation catalyst system jointly developed by Hitachi Zosen Corporation (Hitachi Zosen), Mitsui O.S.K. Lines, Ltd. (MOL) and Yanmar Power Technology Co., Ltd. (YPT).

Risk assessment and other measures

A concept of the methane oxidation catalyst system was designed by Hitachi Zosen and YPT as part of a project which was adopted by Japan’s New Energy and Industrial Technology Development Organization (NEDO) as "Development of Methane Slip Reduction Technology from LNG Fueled Vessels by Improving Catalysts and Engines" under the Green Innovation Fund.

Moreover, MOL, which operates the actual demonstration vessel for the project, and Namura Shipbuilding Co., Ltd. set to build the vessel and conduct design for installing the system on board, have joined to develop specifications of the system together through a risk assessment and other measures.

Environment friendly

ClassNK has conducted its safety review on the co-developed concept design based on its related rules, including Part GF incorporating IGF Code, and issued the AiP upon confirming that the design meets the requirements.

ClassNK will continue to ensure the environment for the early establishment of decarbonisation technologies by providing standards and technical verifications for advanced initiatives.
