Hexicon, which develops deepwater floating wind projects, has concluded a model test as part of its TwinWay demonstration project at MARIN in the Netherlands. The tests involved Hexicon's floating foundation with the patented TLP type mooring system. The company reported that results were "successful" and "as ... desired".

At MARIN, extreme weather and operating conditions were tested, with maximum wave heights corresponding to 20 metres at full scale -- i.e., harsh conditions in the North Sea. The mooring line loads did not exceed estimated values.

Hexicon is planning to install its TwinWind project at Norway's Metcentre no later than 2023. The small pilot project is part of a plan to commercialise new floating wind technology.

”The tests at MARIN have been successful and Hexicon’s floating foundation and mooring system have behaved as they should when exposed to harsh environmental conditions", said Marcus Thor, CEO of Hexicon. "As a next step, the extensive amount of collected data will be processed and compared to results from calculation models. We continue the work with the aim to conduct a pilot for our floating wind platform at Metcentre in 2023.”

The intention of the TwinWay project is to show proof of concept for Hexicon´s floating wind foundation through twin wind-turbines pilot unit designed for, installed, and operated at the Metcentre. The test area is located off Norway’s southern coast and Metcentre has applied for consent for a new larger capacity of 85 MW, expected to be granted in 2021. Hexicon has signed a conditional site exclusivity agreement with a reservation of 6 MW.
