ClassNK grants AiP for Mitsubishi Shipbuilding’s onboard carbon capture system

Classification society ClassNK has issued an Approval in Principle (AiP) for an onboard carbon capture and storage (OCCS) system developed by Mitsubishi Shipbuilding, confirming its compliance with safety and regulatory standards.
The system, which captures CO₂ directly from a ship’s exhaust gases, is part of wider industry efforts to reduce greenhouse gas emissions alongside alternative fuel adoption. ClassNK assessed the design in line with its Guidelines for Shipboard CO₂ Capture and Storage Systems, which form part of the organisation’s broader Transition Support Services.
The AiP validates the technical feasibility and safety of the OCCS technology, supporting its potential integration into commercial shipping operations.
Though OCCS technologies are effective in capturing a fraction of a vessel’s carbon emissions, they add considerable bulk to the ship’s funnel and can suffer from punitive energy demand. Recent developments in the field, though, suggest there may be considerable scope for improvement.
ClassNK stated it would continue to support the safe implementation of onboard carbon capture through guidance and technical reviews.
