Classification society ABS has granted approval in principle to HD Hyundai Heavy Industries (HD HHI) and HD Korea Shipbuilding & Offshore Engineering (HD KSOE) for a large ammonia bunkering vessel design, according to a Ship & Bunker report.
The vessel, with a capacity of 22,000 cubic metres, is designed to supply ammonia as a marine fuel. ABS confirmed the approval in a press release cited by Ship & Bunker, with the announcement made at Gastech 2026. The design follows a joint development project between the two HD Hyundai group companies that was launched earlier this year.
What ABS Reviewed
According to Ship & Bunker, ABS assessed several key elements of the vessel’s design, including:
- General arrangement
- Machinery arrangement
- Ammonia cargo handling system
- Fuel supply system
These components were evaluated against applicable classification society and international requirements, the report states.
Industry Commentary
Gareth Burton, Senior Vice President of Global Engineering at ABS, was quoted by Ship & Bunker saying that bunkering infrastructure represents a critical step for any marine fuel to scale, and that safety must be designed in from the outset.
The approval builds on existing collaboration between ABS and the HD Hyundai group on ammonia-related technologies, including an ammonia cargo handling and bunkering system developed by HD KSOE, Ship & Bunker reported. ABS has also conducted an initial review of the machinery arrangement for HD HHI’s engine room.
Ryu Hong-Ryeul, CTO of HD HHI, told Ship & Bunker that demand for ammonia bunkering vessels is expected to increase as more ships adopt ammonia as a marine fuel.
Does This Matter to You?
As ammonia continues to be developed as an alternative marine fuel, the availability of purpose-built bunkering infrastructure becomes a key factor in its adoption. This approval in principle signals progress toward commercially viable ammonia bunkering vessels, which could eventually support vessel operators and charterers considering ammonia-fuelled newbuilds or retrofits.
For ports and fuel suppliers monitoring the development of alternative fuel infrastructure, this news reflects ongoing efforts by classification societies and shipbuilders to establish safety standards for ammonia handling at scale. The source material does not specify a timeline for construction or deployment of the vessel, so the direct operational impact remains unclear at this stage.
