Ammonia fueled bulk carrier obtained AiP from ClassNK

ClassNK has issued an Approval in Principle (AiP) for an ammonia fueled 200,000 DWT type bulk carrier jointly developed by ITOCHU Corporation, Nihon Shipyard Co.,Ltd., Mitsui E&S Machinery Co., Ltd., Kawasaki Kisen Kaisha, Ltd. (“K” LINE), and NS United Kaiun Kaisha, Ltd.

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. 

“K” Line and partners are looking toward obtaining Alternative Design Approval for the shipbuilding of the Vessel. A risk assessment (Hazard Identification Study – “HAZID”) was recently conducted on the safety of using ammonia as marine fuel, and the basic design of the Vessel was evaluated as “capable of ensuring the same level of safety as ships operating with existing fuel.”

The vessel, which recently received an AiP, was developed by Nihon Shipyard as the part of the “Integrated Project for the Development and Social Implementation of Ammonia Fueled Ships” which was jointly adopted by “the Green Innovation Fund Project / Development for NextGeneration Ships / Development of Ammonia Fueled Ships” of the New Energy and Industrial Technology Development Organization (NEDO).
