DNV has awarded an approval in principle (AIP) to South Korea’s Samsung Heavy Industries (SHI) for a “Fuel Ready” (ammonia, D, S, Ti) class notation for the latter’s 300,000DWT LNG-fueled very large crude carrier (VLCC) design.

SHI has developed a fuel ready concept for a VLCC with dual fuel diesel/ammonia as a potential fuel combination after conversion from dual fuel diesel/LNG. The newly released “Gas Fuelled Ammonia” notation has also been applied in the process.

DNV added that the AIP incorporates the attributes S (structure) and Ti (tank installed). A high-level verification of ammonia applicability for the C-tanks installed on board the VLCC was also performed.

At the time of newbuild, the vessel will still be subject to a full review of documentation requirements pertaining to the applied rules.
