Abstract
Many offshore areas with significant wind resources are located far from electricity demand centers and existing energy transmission networks. Production of hydrogen directly on floating wind turbines is a scalable and modular approach to harnessing these wind resources. This paper presents a design for a floating 15 MW semi-submersible offshore turbine integrated with electrolyzers for hydrogen production and storage tanks. The modified configuration's hydrodynamic performance is simulated under combined aerodynamic and hydrodynamic loading conditions. The modifications led to a 4–5 % increase in pitch and roll inertia of the platform. The maximum acceleration at the nacelle increased by less than 10 %, remaining within acceptable limits, and the maximum power output changed by less than 2 % across all load cases. Mooring line tensions increased by approximately 3 %, demonstrating minimal impact on overall stability. The study demonstrates that onboard hydrogen integration can be achieved without compromising the dynamic response or energy production performance of the floating platform, supporting its viability as a decentralized offshore hydrogen production solution.
