The AiP marks an early technical milestone for a standardised floating production concept aimed at complex offshore conditions.

Lloyd’s Register  has granted Approval in Principle  to Wison New Energies for a new harsh environment FPSO design featuring an internal turret mooring system.

The AiP was presented during the Offshore Technology Conference (OTC) in Houston this week, following an independent concept stage review by LR.

Internal turret FPSOs are widely used in demanding metocean conditions but remain among the most technically complex floating production systems, with critical interfaces between hull, mooring, risers and topside layouts.

By completing an independent concept-stage review, the AiP helps demonstrate that the FPSO concept can progress with a clearer view of key technical and safety considerations, supporting earlier, more confident decision-making by project stakeholders.

Ian Crehan, Global Head of Energies Solutions, Lloyd’s Register, said: “Floating production systems are becoming more complex, and the cost of getting early decisions wrong is rising. Independent assurance at concept stage helps reduce uncertainty and allows projects to move forward with greater technical confidence.”

Wison New Energies said the approval supports its work to develop FPSO designs that can be deployed more rapidly and reliably in challenging offshore regions.

“With design for harsh environment FPSO now completed, Wison has in addition to standard FPSO as well as Gas type FPSO designs already developed, possessed the portfolio to undertake FPSO design for 90% of the current world FPSO demand,” added Loy Wee Meng, Senior Product Manager of Wison New Energies’ FPSO Product Center.
