With support from RWE, the Dutch-Norwegian company SolarDuck has successfully deployed its offshore floating solar project, Merganser.
This pilot project aims to test and validate the structural, mooring, and electrical designs, as well as gather valuable knowledge on the manufacturing, assembly, offshore installation, and maintenance methodologies necessary for the large-scale commercial implementation of offshore floating solar.
Project Location and Specifications
Merganser, with a capacity of 0.5 MWp, is situated in the Dutch North Sea, roughly 12 km off the coast of Scheveningen. This innovative and scalable concept consists of six interconnected platforms engineered to withstand harsh offshore conditions.
The floating platforms were successfully integrated with the mooring system at a water depth of 20 meters. RWE will continue to contribute its offshore expertise and technical support to the pilot project.
RWE’s Perspective
Sven Utermöhlen, CEO of RWE Offshore Wind, stated, “Whether standalone or combined with offshore wind farms, offshore floating solar could unlock additional renewable energy opportunities – especially for countries with lower average wind speeds but ample sunlight.
Merganser provides us with unique insights and firsthand experience in one of the world’s most demanding offshore environments.”
Innovative Platform Design
Deploying solar farms offshore necessitates technology capable of withstanding challenging conditions. SolarDuck’s triangular platform is designed to float several meters above the water, adapting to the waves like a carpet.
This design ensures that critical components remain dry, clean, and stable while maintaining the structural integrity of the semi-submersible floating structure. The design recently received the world’s first certification for OFPV (Offshore Floating Photovoltaic) by Bureau Veritas.
SolarDuck’s Collaborative Effort
Koen Burgers, CEO of SolarDuck, emphasized the collaborative nature of the project, saying, “The successful installation of Merganser demonstrates the dedication of SolarDuck’s team to electrifying the world with offshore floating solar.
However, we are not alone in this endeavor. Our project partner, RWE, along with other partners such as TNO, TU Delft, MARIN, and Deltares, have supported our technology and vision.
Together with numerous supply chain partners, including Damen Shipyards, TMA, and Norsk Hydro, we have transformed hard work into positive change for the energy sector.”
Extensive Monitoring and Data Collection
Over the next two years, Merganser will be remotely monitored using over 180 sensors to track structural loads, connector and mooring loads, electrical performance, and other crucial performance criteria. Deltares, a Dutch independent institute for applied research, will support an extensive monitoring campaign to assess the ecological impact of OFPV.
