MODEC and TOYO receive stamp of approval for blue ammonia FPSO

MODEC and Toyo Engineering Corporation have jointly obtained an Approval in Principle from the American Bureau of Shipping (ABS) for a Blue Ammonia Floating Production Storage and Offloading that will produce ammonia from the gas supplied by Oil & Gas FPSO located nearby.

This Blue Ammonia FPSO is intended to produce and store blue ammonia by using associated gas which has conventionally been reinjected into the reservoir without specific applications. The FPSO is also equipped with Carbon Capture & Storage (CCS) facility to capture not only CO2 generated in the process of converting associated gas to ammonia (NH3), but also CO2 from gas turbine generators (GTG). This makes it possible to minimize CO2 emissions from the FPSO during ammonia production.

Additionally, the hull, which stores and offtakes the produced ammonia, was developed in collaboration with Mitsubishi Shipbuilding Co., Ltd.

This joint development is positioned as the first “Concept Design of Floating Alternative Energy Production Facility” as stated in the Mid-term Business Plan 2024-2026 “Explore a Sustainable Future with Innovation”. The concept of producing blue ammonia offshore is achieved by combining MODEC’s expertise in overall layout, hull design and mooring technology, cultivated in Oil & Gas FPSO projects, with TOYO's expertise in ammonia production process design and FPSO equipment design. This blue ammonia is expected to serve as an alternative fuel and hydrogen carrier in the energy transition.

MODEC considers this AiP as an initial step in the development of a floating solution for alternative energy production and will continue to strive to refine and mature this concept to address the key challenges for commercialization identified through this development, aiming to provide a safe and affordable alternative energy supply solution.
