A group consisting of Mitsui O.S.K. Lines (MOL), Tsuneishi Shipbuilding and Mitsui E&S Shipbuilding have conducted risk assessments on their collaboratively developed ammonia-fueled ocean-going liquefied gas carrier. Following these assessments, the trio’s vessel has been granted approval in principle by ClassNK and Lloyd’s Register.

The mid-size ammonia/LPG carrier benefits from a main engine that can run on ammonia, ensuring no CO2 emissions are released during the combustion process. Furthermore, the vessel will utilize some of the ammonia loaded on board as fuel.

Due to the flammability, toxicity and corrosiveness of ammonia, plus the fact that there are no international regulations for the use of ammonia as a marine fuel, the companies conducted hazard identification studies, after which, both Lloyd’s Register and ClassNK recognized the safety of the ship’s basic design.

The three companies will now continue with the design of the net-zero-emission ocean-going vessel, with delivery expected to take place in 2026.
