Crestwing takes Tordenskiold to rough seas

Danish company Crestwing has towed its prototype Tordenskiold wave energy device to its deployment site off northern Denmark ahead of upcoming installation.

Tordenskiold device has been moved to the deployment site last week, but the weather proved to be ‘too rough’ to anchor the 30-meter long device, according to Crestwing.

“The device is currently at its deployment site – the Port of Frederikshavn – awaiting for the suitable weather window to be anchored. As it looks now, it [the anchoring operation] could take place by this weekend,” the company said in a statement.

Crestwing has recently secured funding for the upcoming two-year demonstration of its half-scale wave energy prototype named Tordenskiold.

Tordenskiold device is to be anchored east of Hirsholmene – located 6 km northeast of Frederikshavn in the Kattegat Strait – where the survivability and power conversion technology of the device will be tested, Crestwing said earlier.

The device falls under the attenuator type of floating wave energy devices which operate parallel to the wave direction, with a hull designed as that of a ship.

These devices capture energy from the relative motion of their two arms as the wave passes them, and according to Crestwing, the company plans to sell its commercial-scale device to energy production companies at home and abroad.
