ClassNK issues AiPs for two sustainable ship designs
Bulk carrier design with a membrane-based OCCS

The classification society ClassNK has issued Approvals in Principle (AiPs) for two new concept designs. One is of a bulk carrier equipped with its own membrane-based onboard carbon capture and storage (OCCS) system and the other one is an ammonia carrier with an IMO Type B Independent Tank setup.
The bulk carrier of unspecified size is the first design to have an OCCS using the membrane separation method. This is expected to have the advantages of a lower power demand and a smaller footprint as compared with amine absorption. The AiP was awarded to Oshima Shipbuilding Co Ltd and Fuji Electric Co Ltd.
Meanwhile the shipbuilder was also the recipient of the 83,000-m3 ammonia carrier AiP. The design provides more cargo capacity and outfitting efficiency but requires more engineering sophistication compared with other cargo tank types.
In a statement, the classification society said that it will continually strive to contribute to advanced decarbonisation initiatives through safety assessments and other strategies.
