DNV ‘Fuel Ready’ AiP for SHI dual-fuel VLCC

SHI has developed a fuel ready concept for a VLCC with dual fuel diesel/ammonia after conversion from dual fuel diesel/LNG. The AiP award confirms the general feasibility of the design and the newly released ‘Gas Fuelled Ammonia’ notation has also been applied.

Ho-hyun Jeong, executive vice president and head of SHI’s engineering operations said that the maritime industry was at a critical juncture in terms of low-carbon ship design. “Through DNV’s AiP for ammonia ‘Fuel Ready’ design, SHI is making an effort for commercialisation of alternative fuel solutions for global shipowners considering newbuildings or converting ammonia-fuelled ships in the future,” he said.

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.

In addition to ‘Fuel Ready’, DNV also offers a dedicated ‘Gas Fuelled Ammonia’ class notation, aimed at shipowners looking to build ammonia fuelled vessels now. The new notations were launched on 1 July 2021 and will come into force 1 January 2022.
