Cable laying moves MeyGen forward

Posted on

Four subsea cables have been successfully put in place for the MeyGen tidal energy project in the Pentland Firth.

The cables are housed in individual bore holes drilled earlier this year, each around 500 metres in length.

They run from the foreshore on the north coast of Caithness and into the Inner Sound of the Pentland Firth. The cables will connect subsea turbines to an onshore power conversion centre, where the power they generate will be fed into the grid.

The aim is to deploy an array of turbines offshore, using technology tested at the European Marine Energy Centre in Orkney. Four 1.5 megawatt (MW) tidal turbines will be deployed next year.

Cable reels were loaded onto the vessel Siem Daya 1 in Hartlepool and then transported to the MeyGen site in Caithness.

The installation process entailed pulling the cable from the vessel through the bore holes using an onshore winch.

Tim Cornelius, chief executive officer for the Atlantis group, the majority owner of the project, said: “This is an excellent result.

“By its very nature the offshore site is a challenging tidal environment, and to complete the installation safely and in line with the programme is a commendable achievement by our onshore and offshore teams, aided by great performance from the vessel.

“After all the planning it is very rewarding to see the offshore infrastructure taking shape for this trail-blazing project.”
