Focal’s Electrical Slip Ring for SR2000 Tidal Turbine

Focal Technologies, a Moog company, has been awarded the contract to supply Scotrenewables Tidal Power with a 6.6 kV electrical slip ring for their new tidal turbine.

Scotrenewables Tidal Power recently launched the 2 MW SR2000 turbine. The 550 tonne machine underwent preliminary tow trials in Belfast Lough, Ireland, before being towed to Orkney, Scotland, to start a grid connected test program.

The Focal 6.6 kV slip ring transmits 2 MW of power and control signals across the turret mooring system to the export cable on the seabed and an integrated absolute rotary encoder facilitates disconnection/connection operations between the SR2000 and the mooring system.

Shawn Taylor, sales and business development manager for Moog Focal, says, “We are very pleased to be supporting Scotrenewables on their SR2000 platform with our marine rotary offerings. It is certainly exciting to be designing and delivering technologies which are helping companies like Scotrenewables make reliable tidal energy solutions a reality.”
