Simec Atlantis Energy has redeployed two Andritz Hydro tidal turbines at its 6MW MeyGen Phase 1A array in the Pentland Firth off Caithness in Scotland.
The company said the two 1.5MW machines had restarted generation at full capacity following maintenance at its Nigg Energy Park base in Easter Ross.
Atlantis has meanwhile retrieved an Atlantis 1.5MW turbine for ancillary systems maintenance at Nigg with reinstallation slated for a December tidal window.
The offshore operations were completed within time and budget by Atlantis Operations UK, a division of SIMEC Atlantis Energy, the company said.
A third Andritz Hydro unit retrieved in August is also scheduled for redeployment in December following completion of its scheduled inspection and maintenance programme.
Atlantis has meanwhile appointed Andy Richardson to the post of chief operating officer, joining its senior management team based in London.
Robinson was formerly head of asset management and engineering manager at Alstom Power Service UK and director of thermal generation at EDF and was most recently COO of Australian energy company Stanwell.
