With the support of RWE, Dutch-Norwegian company SolarDuck has installed its offshore floating solar project, Merganser.
The 500kW pilot project aims to test and demonstrate the structural, mooring and electrical designs and acquire knowledge about manufacturing, assembly, offshore installation and maintenance methodologies required for large-scale commercial deployment of floating solar.
Merganser is located in the Dutch North Sea, approximately 12km off the coast of Scheveningen.
The scalable concept consists of six interconnected platforms that can withstand extreme offshore conditions.
The floating platforms were successfully connected to the mooring system in water depths of 20 metres.
RWE will continue to provide its offshore know-how and technical support to the pilot project.
RWE Offshore Wind chief executive Sven Utermohlen said: “Standalone or also in combination with offshore wind farms, offshore floating solar could open up further offshore renewable energy opportunities – especially for countries with lower average wind speeds but lots of sunlight.
“With Merganser, we are gaining unique insights and first-hand experience in one of the most challenging offshore environments in the world.”
Taking solar farms offshore requires technology able to withstand rough offshore conditions and SolarDuck’s triangular-shaped platform is designed to float several metres above the water, following the waves like a carpet, said the company.
In this way, the design is keeping critical components dry, clean and stable, as well as securing the structural integrity of the semi-submersible floating platform.
The design received recently the world’s first certification for OFPV by Bureau Veritas.
SolarDuck chief executive Koen Burgers said: “The successful installation of Merganser is proof of the dedication of SolarDuck’s team to electrify the world with offshore floating solar.
“However, we are not doing this alone.
“Our project partner, RWE, is a supporter of our technology and vision, in addition to other partners such as TNO, TU Delft, MARIN, and Deltares.
“Together with numerous supply chain partners, including Damen Shipyards, TMA, and Norsk Hydro, we have turned hard work into a positive change for the energy space.”
Over the coming two years, Merganser will be monitored remotely with its more than 180 sensors fitted to monitor structural loads, connector and mooring loads and electrical performance, among other important performance criteria.
Further to the above, Deltares – a Dutch independent institute for applied research – will support an extensive monitoring campaign on the ecological impact of OFPV.
