(Helenic Shipping/Bureau Veritas) Bureau Veritas (BV) has released an Ammonia-Prepared notation and has developed a Rule Note for ammonia as a marine fuel to support ship owners, designers, shipyards, and charterers in advancing their journeys toward using ammonia and a zero carbon future. Ammonia-Prepared is applicable to new-builds and certifies that a ship has been designed and constructed to be converted to use ammonia as fuel at a later date. The notation targets the spaces and structural components that will accommodate future ammonia fuel tanks, fuel handling equipment and ammonia vapor treatment installations. Ammonia-Prepared also covers specific requirements for the conversion of engines and boilers from using fuel oil, LNG or multiple fuels to ammonia. The notation was developed in collaboration with different stakeholders including ship owners, equipment makers, designers and shipyards building on our expertise across the value chain.
