ClassNK issues AiP for large ammonia fueled BC jointly developed by MOL and MITSUI
The design calls for a main engine fueled by ammonia, which emits no CO2 when burned, thereby achieving zero CO2 emissions during the voyage.
ClassNK has issued an Approval in Principle (AiP) for a large ammonia fueled 210,000 DWT bulk carrier jointly developed by Mitsui O.S.K. Lines, Ltd. (MOL) and MITSUI & CO., LTD (MITSUI).
Ammonia is expected to be used as a ship fuel for decarbonization since it does not emit CO2 when combusted. Meanwhile, adequate safety measures are imperative as it has been pointed out that ammonia is toxic to humans and corrosive to materials.
MOL and MITSUI have jointly determined the size and specifications for the vessel, and its design has been entrusted to Mitsubishi Shipbuilding Co., Ltd.
ClassNK carried out the review of this jointly developed design in line with Part C of its guidelines and issued the AiP on verifying conformity to the prescribed requirements. In addition, risk assessment (HAZID) will be conducted to confirm that no unacceptable risks exist at the basic design stage and to identify items to be considered in the detailed design.
