DNV AiP FOR SHI'S AMMONIA-READY VLCC CONCEPT

DNV AiP FOR SHI'S AMMONIA-READY VLCC CONCEPT

Friday, August 20, 2021 

Classification society DNV has awarded an Approval in Principle (AiP) to Samsung Heavy Industries (SHI) for a 'Fuel Ready' (ammonia, D, S, Ti) class notation for a 300,000 dwt LNG fuelled 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 AiP award confirms the general feasibility of the design. It was found that there are no showstoppers in realising the DNV class notation 'Fuel Ready' after examining the shipyard’s drawings. The newly released 'Gas Fuelled Ammonia' notation has been applied in the process.

Ho-hyun Jeong, EVP and Head of SHI's Engineering Operations, said: “The global maritime industry is at a critical juncture in terms of being ready to respond with low-carbon ship design. Through DNV’s AiP for ammonia 'Fuel Ready' design, SHI is making an effort for commercialization of alternative fuel solutions for global shipowners considering newbuildings or converting ammonia-fuelled ships in the future.”

“We are very happy to work with SHI in this innovative 'Fuel Ready' VLCC concept,” said Knut Ørbeck-Nilssen, CEO DNV Maritime. "DNV has been pioneering the research and development of viable future marine fuels, including ammonia. As a trusted voice to tackle global transformations, our role is to support the industry in bringing new low-carbon ship designs to life in a safe and sustainable manner."

The AiP incorporates the attributes S (structure) and Ti (tank installed). A high-level verification of ammonia applicability for the C-tanks installed onboard 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.
