MODEC has been awarded an Approval in Principle (AiP) from Bureau Veritas Group and American Bureau of Shipping - ABS for a Floating Storage and Injection Unit “LCO₂ FSIU” that is capable to receive, temporarily store and ultimately inject carbon dioxide (CO₂).
The FSIU would be able to receive LCOâ‚‚ transported in low pressure condition, store, and inject it into subsea wells at high pressure for permanent sequestration, which eliminates a need for onshore LCOâ‚‚ receiving plant and pipeline to injection wells. The unit is engineered for a maximum COâ‚‚ injection capacity of 10 million tonnes per annum (MTPA), with a minimum total tank storage capacity of 100,000 mÂł.
To support uninterrupted injection operation, the FSIU will feature both tandem loading at the aft and simultaneous side-by-side loading at the midship port side, enabling flexible and efficient LCOâ‚‚ transfer from LCOâ‚‚ carriers, up to 90,000 m3 capacity (tandem) and up to 50,000 m3 (side-by-side). The FSIU hull was developed in collaboration with Mitsubishi Shipbuilding Co. Ltd. (MSB), while the mooring system incorporates a SOFEC External Turret to allow dual loading operation as well as station keeping in non-directional environment as often found in Southeast Asia. The FSIU will also be equipped with diesel engine generators integrated with a carbon capture system on the topside, minimizing operational COâ‚‚ emissions.
This concept was developed in collaboration with Mitsui OSK Lines Ltd. (“MOL”), to leverage their experience and market position with LCO₂ carriers and its proven methods of safe storage, transport and offloading.
