MISC Berhad (MISC) and China Offshore Engineering & Technology Company Limited (China Offshore) have received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for their pioneering Ammonia Floating Production Storage and Offloading (FPSO) design.
The announcement was made on 2 December 2025 during Marintec 2025 in Shanghai, China.
The FPSO adapts proven onshore ammonia production technology for offshore use, converting previously unutilised hydrocarbon gas into high-value Blue Ammonia, stored onboard under cryogenic conditions.
The facility allows upstream developers to monetise gas that would otherwise be reinjected, shortening the ammonia supply chain and improving well-to-gate carbon emissions.
Zahid Osman, President and Group CEO of MISC, said: “The Ammonia FPSO concept is aligned with MISC’s commitment to #deliveringProgress and accelerating the pathway to deliver more energy with less emissions.
“This new concept is a result of strategic collaboration that drives impactful change that is needed in our industry. By adapting a proven onshore technology for offshore use, we are not just creating a new concept, we are supporting the offshore industry to achieve its lower carbon ambitions.”

Miguel Hernandez, ABS Senior Vice President, Global Offshore, added: “ABS is proud to share our deep insight into the safety challenges of ammonia, along with our extensive technical expertise on complex floating production facilities.”
The FPSO will receive feed gas from nearby host facilities, such as oil-producing FPSOs. Once storage reaches capacity, liquid ammonia can be exported directly to Liquid Ammonia Carriers (LAC).
Its modular topside design can process varying feed gas specifications, producing ammonia at 99.8 per cent purity.
Currently in the Pre-FEED phase, the project achieved AiP in Q4 2025. Pre-FEED, including CAPEX and OPEX assessments, is scheduled for completion in Q1 2026.
The FPSO is designed for an annual production capacity of 1.0 million tonnes of liquid ammonia.
The project is jointly developed by MISC and China Offshore, in collaboration with ammonia technology licensors Kellogg Brown & Root (KBR) and LNT Marine (LNT A-BOX System). ABS is providing an independent technical review and validation of the project’s feasibility and safety.
