Japanese firms receive design approval for ammonia-powered bulk carrier

Japanese classification society ClassNK granted Approval in Principle (AiP) for the design of an ammonia-powered bulk carrier which was jointly developed by Japanese shipping major Mitsui O.S.K Lines (MOL) and trading firm Mitsui.

The 210,000-dwt ammonia-powered bulk carrier was designed by Mitsubishi Shipbuilding.

It is claimed that the bulk carrier will not emit any carbon dioxide emissions while running on ammonia. Also, the vessel's design features two separate ammonia fuel tanks on deck to maximise its range and effectively utilise cargo space.   

Additionally, a risk assessment will be conducted by Class NK to evaluate the magnitude and frequency of potential safety hazards onboard the vessel.

Ammonia is very toxic, and thorough risk assessments must be carried out during the vessel design phase. Recent safety studies conducted under the NoGAPS (Nordic Green Ammonia Powered Ship) project have designated fuel preparation room and tank connection areas onboard ammonia-powered vessels as high-hazard areas for both crew and vessel.
