ClassNK has issued an approval in principle (AiP) for an ammonia fuelled LPG/NH₃ carrier, applied for jointly by Kawasaki Heavy Industries, Ltd. and MITSUI E&S Co., Ltd. The certification demonstrates its feasibility from regulatory and safety perspectives. Ammonia, which does not emit CO₂ during combustion, is expected to see wider use as a zero-carbon fuel for ships. At present, various studies and development efforts are underway to bring ammonia fuelled ships into practical use. International standards ClassNK released the ‘Guidelines for Ships Using Alternative Fuels’ to support pioneering initiatives in this field In 2021, prior to the establishment of specific international standards for the use of ammonia as fuel for ships, ClassNK released the ‘Guidelines for Ships Using Alternative Fuels’ to support pioneering initiatives in this field. The guidelines stipulate requirements for installation, controls, safety devices, etc., aiming to minimise the risks to ships, seafarers, and the environment associated with the use of ammonia fuelled ships. Furthermore, in December 2024, the ‘Interim Guidelines for the Safety of Ships Using Ammonia as Fuel’, which ClassNK had submitted a proposal for safety requirements to the IMO through the Government of Japan, were approved at MSC 109. Design concept ClassNK reviewed the design concept of the vessel based on 'Part C-2: Guidelines for the Safety of Liquefied Gas Carriers Using Ammonia as Fuel (Edition 3.0.2)' and 'Part C-3: Additional Safety Measures for Engine Rooms (Edition 3.0.2)' of the 'Guidelines for Ships Using Alternative Fuels (Edition 3.0)', and examined the risk assessment through HAZID. Upon confirming that the prescribed requirements had been met, ClassNK issued AiP. ClassNK will continue to contribute to new technology development and social implementation, including safety assessments.
