ClassNK has issued an Approval in Principle (AiP) for a large ammonia-fueled 210,000 DWT bulk carrier jointly developed by MOL and MITSUI.
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, a 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.
ClassNK will continue to support those companies as the certification body and will strive to provide appropriate standards for ammonia-fueled ships through the expertise gained from the collaboration
ClassNK has also been involved in projects aiming for zero-emission ships using ammonia fuel in terms of safety assessment and has issued its “Guidelines for Ships Using Alternative Fuels” as a necessary standard to minimize the risks related to ammonia-fueled ships for the ships, crews, and environment by stipulating requirements for installation, controls, and safety devices.
