LR has awarded an Approval in Principle to Exmar for its ammonia (NH3) fuelled 40,000 m3 Midsize Gas Carrier (MGC), 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, according to the company's release.
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).
A risk assessment was also conducted, using Exmar’s extensive knowledge and experience of operating ammonia carriers, to ensure that risks arising from the use of ammonia fuel affecting persons onboard, the structural strength or the integrity of the ship are addressed in accordance with LR’s ShipRight Procedure for Risk-Based Designs (RBD). This included a Hazard Identification (HAZID) study which led to the Approval in Principle.
