Hanwha Power wins approval for concept design of 22,000-cubic-meter LNG bunkering vessel

Hanwha Power said Wednesday it received approval in principle from the American Bureau of Shipping for the concept design of a 22,000-cubic-meter LNG bunkering vessel at Gastech 2026, the world's largest gas and energy exhibition, held in Bangkok, Thailand.

With the approval, Hanwha Power has completed a full lineup of mid- to large-scale LNG bunkering vessels ranging from 7,500 cubic meters to 22,000 cubic meters.

A key feature of the design is its dual-cargo capability, allowing the vessel to carry not only LNG but also ammonia — a next-generation eco-friendly fuel drawing growing attention in the industry. The design incorporates high-manganese steel cargo tank technology, enabling the vessel to adapt to future clean-fuel transitions with minimal design modifications.

Taking into account the coastal operating patterns typical of bunkering vessels, the design introduces a hybrid electric propulsion system linking an onshore power supply with an energy storage system, minimizing harmful emissions during berthing and coastal navigation. The vessel also integrates core group technologies including dual-fuel generators, an energy storage system, an electric power and system integration unit, an integrated automation system and a cargo handling system.

"This approval again demonstrates Hanwha Power's technical credibility and commercial viability in the global eco-friendly vessel market," said Kim Hun-min, head of Hanwha Power's ship solutions division. "We will continue to provide global shipowners with optimal integrated green solutions, drawing on the differentiated eco-friendly technology capabilities within our group."

Hanwha Power established its ship solutions division in 2023 and has since been actively pursuing vessel conversion, eco-friendly fuel propulsion and energy efficiency projects.
