FTLP and Semi-Submersible Deepwater Foundations Value Comparison

This report is a public summary detailing a collaborative study aimed at evaluating the life cycle value of the Fixed Tension Leg Platform (FTLP) developed by Oil State Industries (OSI) in comparison to conventional semi-submersible floating foundations. The study, which involves contributions from ORE Catapult, Seaway7, and Flotation Energy, is designed to inform industry stakeholders and policymakers about the potential advantages of the FTLP solution in the context of offshore wind applications. It addresses the evolving policy landscape, particularly the Department for Energy Security and Net Zero's initiatives to promote innovative floating wind solutions. The report outlines the importance of assessing alternative foundation concepts not only on technical grounds but also on their economic viability throughout their lifecycle. It emphasizes the need for a comparative Engineering, Procurement, Construction, and Installation (EPCI) study to understand the material value of different foundation types, particularly as the floating offshore wind sector moves towards commercial-scale deployment.
