ABS grants AIP to Hanwha's 22,000m³ LNG bunker-vessel concept
ABS announced approval in principle on October 23 for Hanwha Power's 22,000m³ LNG bunker-vessel concept, with provision for future conversion to ammonia service and hybrid coastal operation.
The story explained
ABS announced approval in principle on October 23 for Hanwha Power’s 22,000m³ LNG bunker-vessel concept, with provision for future conversion to ammonia service and hybrid coastal operation.
Hanwha’s high-manganese-steel containment technology is intended to carry LNG initially while allowing later conversion to ammonia service. This describes a design pathway, not an already-converted or operating ammonia bunker vessel.
Three dual-fuel generating engines provide primary power, assisted by energy storage for peak shaving, transient response and blackout prevention. The arrangement targets coastal and berth operation; the announcement gives no quantified efficiency or emissions guarantee.
AIP is a concept-stage milestone, not a construction contract, final classification certificate or delivery. The release identifies no owner order, construction yard, build schedule or pump-and-valve supplier.
Why it matters
Conversion between LNG and ammonia service requires cargo-system compatibility review; concept AIP does not certify individual valves for cryogenic, material or sealing requirements.
