Lloyd’s Register (LR) has awarded an Approval in Principle to EXMAR for its ammonia (NH 3 )-fueled 40,000 m 3 Midsize Gas Carrier, a significant milestone for the progression of alternative fuels in shipping. Jiangnan Shipyard was responsible for the ship design while Wärtsilä Gas Solutions provided all input for the ammonia fuel gas supply system. Wärtsilä began combustion trials using ammonia last March (2020). Testing continues on both dual-fuel and spark-ignited gas engines. These will be followed by field tests in collaboration with ship owners from 2022. ( Earlier post .) The Novel Technology Evaluation included an overall examination of fundamental aspects of the design and compliance with LR’s Rules and Regulations for the Classification of Ships and for the Carriage of Liquefied Gases in Bulk (for Gas Ships), incorporating the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code).
