AiP for LPG carrier design with Daihatsu reformer

The vessel is designed to be equipped with an LPG reformer developed jointly by Daihatsu Diesel and Osaka Gas, and a dual fuel engine developed by Daihatsu Diesel.

The LPG reformer will convert LPG into synthetic methane gas. The engine designer has outlined the reforming principles behind the process: desulphurising LPG, methanising it by steam reformation and then removing carbon dioxide and water to leave synthetic methane. The resulting synthetic methane can be combusted in engines alongside LNG.

Speaking on the occasion, ClassNK Senior Executive Vice President T. Shigemi said “We have cautiously confirmed the design’s safety and are proud to be involved with this project. LPG is starting to become an option in the maritime industry and we have high expectations for the possible benefits that its use may bring in terms of environmental safety and efficiency.”

Daihatsu Diesel President S. Kinoshita said “We have developed dual-fuel engines from the viewpoint of global warming prevention, and this LPG reformer will provide more options for customers. We would like to make further efforts toward a zero-carbon society. I thank ClassNK and our partners for their efforts and cooperation in making the concept design and safety assessment.”

The design was developed in cooperation with Iino Gas Transport, Osaka Gas, Izumi Steel Works, and Miura Shipbuilding in terms of safety assessments.
