Sevan Deepwater Technology and LATTICE International AS are conducting joint evaluations of a next-generation floating storage and injection unit (FSIU) concept for the carbon capture and storage (CCS) industry.

The work centres on a large liquid CO2 floating storage and injection unit design that combines LATTICE’s pressure vessel technology (LPV) for large-scale liquefied gas storage with Sevan’s cylindrical hull design. Initial estimates show a 19% reduction in hull size, while increasing cargo capacity by 40%.

Sevan Deepwater Technology, a member of the Seatrium Group, and LATTICE International AS state that the current engagement is non-exclusive and does not represent a commercial commitment at this stage.

If the evaluation results are positive, the companies will investigate and consider next-step opportunities to offer the optimised FSIU solution more broadly to the global energy and CCS industry.
