BW Offshore has unveiled a floating blue ammonia FPSO concept developed in collaboration with McDermott International, combining offshore production, carbon capture and direct export to convert surplus natural gas into lower-carbon fuel.
The floating production, storage and offloading (FPSO) concept is designed to process up to 3 million cubic meters of gas per day, producing more than one million tonnes of ammonia annually.
It incorporates carbon capture technology designed to capture and compress up to 99% of the CO₂ generated during production for export to geological sequestration or other approved uses.
BW Offshore said the concept is intended to align with prevailing international criteria for low-carbon hydrogen derivatives, with an estimated carbon intensity of around 0.5 tonnes of CO2 per tonne of ammonia. Options are available to further reduce emissions from onboard power generation systems.
The FPSO unit would be located close to offshore gas sources and CO2 storage sites. Natural gas would be transported via subsea flowline and converted onboard into hydrogen and then ammonia using a low-carbon process.
By placing ammonia production offshore, the concept avoids the land, permitting and infrastructure constraints associated with large onshore facilities. Liquefied ammonia would be stored in refrigerated tanks within
