ClassNK Greenlights Mitsubishi’s CCS System Onboard Ships

ClassNK has issued an approval in principle (AiP) for an Onboard Carbon Capture and Storage system (OCCS) developed by Mitsubishi Shipbuilding.

The certification confirms its feasibility from regulatory and safety perspectives.

Interest in CO2 capture the method from exhaust gases is growing alongside fuel conversion as part of efforts to reduce GHG emissions from ships.

In response, the development of OCCS is progressing. To support the smooth development and introduction of related technologies, ClassNK has published the 'Guidelines for Shipboard CO2 Capture and Storage Systems' as a subset of the ClassNK Transition Support Services.

This guideline outlines safety requirements for OCCS and its installation on ships.

ClassNK reviewed the design of the system based on those guidelines, and upon confirming compliance with the prescribed requirements, the certification group issued the AiP to Mitsubishi Shipbuilding.
