ABS Approves HD HHI and HD KSOE Design for Bunker Vessel Capable of Supplying Ammonia Fuel

ABS has granted HD Hyundai Heavy Industries (HD HHI) and HD Korea Shipbuilding & Offshore Engineering (HD KSOE) an approval in principle (AIP) for the basic design of a 22,000 CBM bunkering vessel capable of supplying ammonia as marine fuel. The approval, announced at Gastech 2026, results from a joint development project initiated earlier this year, where ABS evaluated the design’s general arrangement, machinery arrangement, ammonia cargo handling system, and fuel supply system against class and international requirements.

Gareth Burton, ABS Senior Vice President, Global Engineering, highlighted the significance of the AIP in supporting fuel flexibility and advancing the safe bunkering of ammonia. Ryu Hong-Ryeul, Chief Technical Officer of HD HHI, noted that the approval marks a significant milestone toward the commercialization of ammonia bunkering vessels, as demand for this fuel is expected to grow with the adoption of ammonia-fueled ships.
