2H specialises in designing robust, fit-for-purpose, and cost-effective foundations and substructures for fixed offshore wind projects. Our expertise lies in using fully coupled integrated load analysis (ILA) or uncoupled analysis to ensure optimal performance. We understand the critical drivers for fixed wind foundations and employ advanced tools and methodologies to balance cost and risk from the initial project concept through to detailed design and successful offshore installation.

2H has designed all traditional steel substructure types for fixed wind and has an extensive track record in oil & gas foundations supported by real-world transportation and installation experience from installing foundations offshore.
