August 15 (Renewables Now) - Swedish marine energy developer Minesto AB said today it is launching new testing of its utility-scale DG500 tidal energy subsea kite at the Holyhead Deep site off North Wales.
The system was deployed at the site in early October 2018 and the company concluded an offshore commissioning and test programme the following month. The device was then upgraded over the winter.
Some of the offshore site infrastructure in the Holyhead Deep was reinstalled recently and the DG500 kite system was towed to site and re-connected to the seabed foundation. The continued testing operations will help further optimise the Deep Green technology and reduce the cost.
Chief technology officer Bernt Erik Westre explained that the new system is different from last year’s version in several key areas. “The new method of installing the kite by towing and connecting it to the infrastructure at the foundation rather than on the surface worked really well. By eliminating offshore kite lifts, we have expanded our operational ability and capacity, while lowering the total cost level at the same time,” he said.
