OpenHydro

The first 250 kW Open Hydro turbine was tested at the European Marine Energy Centre (EMEC) Fall of Warness site from 2006, and was connected to the Orkney electricity grid in May 2008.

[8] The seventh generation 6 m diameter Open Hydro turbine was installed at the same EMEC site in April 2014.

[9] The turbine on test at EMEC was mounted on two piles, allowing it to be raised out of the water for maintenance, as shown in the photo (right).

The turbines were lowered to the seabed, and subsequently removed, by a specially designed catamaran barge, the OpenHydro Triskell.

The device is expected to be removed before the end of 2024 by the next company to test at FORCE Berth D, BigMoon Canada Corp.[17] OpenHydro was about to develop the 14 MW Normandie Hydro project at La Raz Blanchard, Brittany, to be operated by EDF Energies Nouvelles.
