Burckhardt Compression to supply technology for first purpose-built ammonia bunkering vessel

Burckhardt Compression has secured a contract to supply its Laby compressor technology for what is expected to be the world’s first vessel built specifically to bunker ammonia as a marine fuel. The project marks a significant step in the shipping industry’s effort to transition toward low- and zero-carbon fuels, the company said.

The ship, commissioned by Itochu Corp. and its Singapore-based subsidiary Clean Ammonia Bunkering Shipping Pte. Ltd., will be constructed by Sasaki Shipbuilding Co. The 5,000-cubic-meter vessel is scheduled for delivery in 2027 and is designed to support emerging ammonia supply chains as global operators test and deploy new marine-fuel options.

Burckhardt’s Laby compressor will be part of the vessel’s fuel-handling system, enabling the safe transfer of ammonia during bunkering. The technology is known for its hermetically sealed, oil-free design aimed at preventing leakage and enhancing safety when handling toxic or corrosive gases.

“This order underscores our strong commitment to enabling the maritime energy transition,” said Andreas Brautsch, president of Burckhardt’s systems division. “Our Laby technology is ideally suited for the demanding requirements of ammonia service.”

The vessel is being developed in cooperation with Nissin Gas Engineering, which manufactures liquefaction systems for LPG, ammonia and other specialized applications.

Ammonia has gained attention as a potential marine fuel because it emits no carbon dioxide at the point of combustion. Industry developers are working to establish the bunkering and handling infrastructure required to scale its use.

“We are proud to contribute to this historic first for the industry,” Brautsch said. “The successful operation of this ammonia bunkering vessel will help set the standards for future clean-fuel supply chains worldwide.”
