The American Bureau of Shipping (ABS) has approved a floating production storage and offloading (FPSO) design developed by offshore platform company SBM Offshore, focused on blue ammonia production.

Traditionally, an FPSO is a ship-shaped facility used to process, store, and offload oil and gas offshore. In this project, it will be adapted for blue ammonia production.

The unit is designed to process offshore natural gas by converting it into ammonia, while capturing CO2 through carbon capture and storage (CCS) technology.

The resulting ammonia will be supplied to the power sector, maritime transportation, and the global ammonia market.

“We are seeing rapid innovation and new developments around ammonia as an alternative fuel, whether as a carrier of hydrogen or as a fuel in its own right,” ABS senior vice president, Global Offshore, Miguel Hernandez, said.
