Overhauled MeyGen turbine up for redeployment

One of the repaired Andritz Hydro Hammerfest (AHH) tidal turbines has been mobilized for reinstallation at the MeyGen tidal turbine array in the Pentland Firth, off Scotland.

Loaded onboard offshore construction vessel Seabed Stingray, owned by Swedish subsea operations provider Swire Seabed, the refitted 1.5MW tidal turbine is currently at the MeyGen tidal array location where it will be reinstalled and returned to service.

The subsea operations at an offshore site between Scotland’s northernmost coast and the island of Stroma, where the array is location, are scheduled to last until October 21, 2018, according to the notice issued to mariners.

The MeyGen Phase 1A tidal energy array has been operating at half of its 6MW capacity since July 2018, after the company behind the project SIMEC Atlantis Energy retrieved two AHH turbines due to a generator fault by the onboard monitoring systems.

Both AHH turbines, totaling 3MW in capacity, will be returned to service to MeyGen Phase 1A array in the fourth quarter of 2018, Tim Cornelius, the Chief Executive of SIMEC Atlantis, confirmed earlier.

Each turbine for the Phase 1A of the MeyGen project is rated at 1.5MW, and consist of three AHH turbines, and one Atlantis’ AR1500 machine.

In April 2018, the MeyGen Phase 1A project completed the construction phase and officially entered the 25-year operations phase.

It is currently the world’s largest tidal stream array which holds a world record for monthly production from a tidal stream array having generated 1,400MWh this March.
