Two players, MISC and China Offshore Engineering & Technology Company (China Offshore), have secured an approval in principle (AiP) from the American Bureau of Shipping (ABS) for their concept of an ammonia floating production storage and offloading (FPSO) unit.
The AiP for the ammonia FPSO design was received from the American Bureau of Shipping on December 2, 2025, in Shanghai, China. This floater solution is said to adapt proven onshore production technology for offshore operations, transforming unutilized hydrocarbon gas from nearby offshore facilities into high-value blue ammonia, which is stored onboard at cryogenic conditions.
