SolarDuck, RWE Install Offshore Floating Solar Pilot Merganser Off Dutch Coast

Dutch-Norwegian company SolarDuck, together with RWE, has installed its offshore floating solar (OFPV) pilot project ‘Merganser’ 12 km off the Dutch coast. The 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 OFPV.

Merganser has a capacity of 0.5 megawatt peak (MWp) and is located in the Dutch North Sea, approximately 12 kilometers 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 a water depth of 20 meters. RWE will continue to provide its offshore know-how and technical support to the pilot project.

Sven Utermöhlen, CEO of RWE Offshore Wind: “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 that can withstand rough offshore conditions. SolarDuck´s triangular-shaped platform is designed to float several meters above the water, following the waves like a carpet. 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 structure. The design received recently the world’s first certification for OFPV by Bureau Veritas.

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.
