By addressing technological gaps specific to floating substations, the anticipated updates to the DNV-ST-0145 standard will play a crucial role in supporting the deployment of floating wind projects, ultimately contributing to a cleaner, more resilient energy future.
DNV has launched Phase 2 of its Floating Substation joint industry project (JIP), which aims to establish standards for offshore substations in the growing floating wind sector. This new phase will play a key role in refining guidelines and closing technology gaps, with participation now expanding to 19 leading industry players. Phase 1 of this collaborative effort had already united a broad range of stakeholders, including transmission operators, developers, component suppliers, EPC contractors, and yards, to address the unique challenges of floating offshore substations.
Offshore substations are essential to the expansion of floating offshore wind, serving as hubs that connect multiple turbines and deliver renewable energy to the grid. However, designing and implementing these substations presents distinct challenges, such as the need for high-voltage dynamic cables and electrical systems that can withstand the movements of floating structures. By addressing the technological and regulatory gaps, the JIP aims to support the wind industry in achieving its full potential and advancing the global energy transition.
Phase 2 of the JIP will concentrate on critical components such as high voltage equipment, dynamic cables, and the broader aspects of marine systems and operations. These efforts are crucial for updating DNV-ST-0145, the world's first standard applicable to floating substations.
The initiative boasts the involvement of major industry players, including ABB, Aibel, Atlantique Offshore Energy, CSEPDI, EDF Renouvelables, GE, Vernova, Hitachi Energy, IV & Nevesbu, Navantia Seanergies, Orient Cable, Rambøll, Red Eléctrica, RTE, Seatrium, Statnett, TotalEnergies, COP, Iberdrola/Scottish Power, and Saipem. This broad participation underscores the global importance of the project. By facilitating the deployment of floating substations in deeper waters, DNV is setting new technological benchmarks.
'Updating DNV-ST-0145 to include floating substations will enhance the scalability of floating wind technology and reduce associated risks,' said Kim Sandgaard-Mørk, Executive Vice President for Renewables Certification at DNV. 'This update highlights our commitment to advancing floating wind energy and drive renewable innovation. The Floating Substation JIP, supported by extensive internal collaboration throughout DNV and external partnerships with major industry leaders, underscores the project’s global impact and our commitment to delivering robust, comprehensive and scalable solutions for the energy transition.'
Call for participants: DNV invites additional stakeholders to join this pivotal initiative. As the JIP moves forward with Phase 2, there are still opportunities for industry leaders, innovators, and experts to contribute to shaping the future of floating wind technology by helping refine crucial standards. Interested parties are encouraged to contact DNV to learn more about how they can get involved.
