Aberdeen-based subsea cable specialist, Hydro Group has secured a milestone marine renewables contract with Atlantis Resources to supply connection systems to a multi-turbine tidal stream energy project near Pentland Firth, Scotland.
Hydro Group Secures milestone marine renewables contract

The developers of the MeyGen project say they've raised more than £50 million to finance the initial stage (phase 1A) of the ground-breaking 398 MW tidal array.

The project consists of four submerged turbines generating 6 MW being installed as well as the construction of all onshore infrastructure to support the project.

Atlantis Resources, majority owner of MeyGen Ltd., selected Hydro Group to supply the complete export connection system for one of the tidal turbines, and is currently finalising details for the second phase of the project.

“As the first of its kind in the world, the MeyGen project is a true milestone in the marine renewable sector, and being part of it is a significant step for Hydro Group, reinforcing our commitment to supporting renewable system requirements,” said Doug Whyte, Hydro Group's managing director.

The  calls for Hydro Group to provide a single housing for a hybrid with a power output of 6.5 kV, incorporating the power and communication connection system, mechanical loading system, and fibre optic and instrumentation lines.

“Our system is designed for 25 years’ service life with an in-built corrosion protection system meaning minimal maintenance is required and operational costs are reduced in the long term, a focus that is of high importance in the current climate," Whyte said.

 “To ensure further savings, we design our systems to mate and de-mate - connect and disconnect - in less than one hour to ensure offshore installation costs, the highest cost in any marine infrastructure, are minimised,” he added.

When fully completed, the MeyGen project will have the ability to provide clean, sustainable, predictable power for 175,000 homes in Scotland from up to 269 tidal turbines secured to the seabed, with the first power to the national grid expected to be delivered in 2016.

“The project should further enhance industry confidence in tidal energy, helping unlock its potential as a serious contributor to future energy systems.” Whyte said.
