The Japan-based shipping giant Mitsui O.S.K. Lines (MOL) and Mitsui & Co have received approval in principle (AiP) from classNK for the design of a large ammonia-powered bulk carrier.
As explained, MOL and Mitsui jointly determined the size and specifications of the vessel, and both companies entrusted Mitsubishi Shipbuilding for design of the vessel. The AiP covers a “210,000 deadweight cape size” bulker.
The design calls for a main engine fueled by ammonia, which emits no CO2 when burned. The vessel will also feature two ammonia fuel tanks on deck to maximize the cruising range for various routes and to make the most effective use of cargo space.
Furthermore, classNK is scheduled to conduct a risk assessment to confirm that no unacceptable risks exist at the basic design stage and to identify items to be considered in the detailed design, which will incorporate safety measures fully taking into account the toxicity of ammonia, and other factors.
