Tidal Energy Ltd (TEL), a privately owned technology development, is working on an innovative tidal stream generator called DeltaStream. It has identified a demonstration test site at Ramsey Sound and is in the process of getting the necessary consent licences to install a 1.2 MW full-scale demonstration DeltaStream device next year for a 12 month test period.
The DeltaStream device is a nominal 1.2MW unit which sits on the seabed without the need for a positive anchoring system, generating electricity from three separate horizontal axis turbines mounted on a common frame.
The project has been financed so far by shareholders and a capital grant from the European Regional Development Fund (ERDF) administered by the Welsh Assembly Government. The funding has brought the project to the stage where it is ready to award contracts for the final design, construction, deployment and test of the DeltaStream device.

TEL is advertising for a contractor who will plan, manage and coordinate the deployment, installation and subsequent recovery and decommissioning of the DeltaStream tidal device at the site, 1.2km offshore in Ramsey Sound.
The contract includes manoeuvring and transporting the DeltaStream generator from onshore to the seabed. The DeltaStream unit weighs 300t and consists of a 36m-wide structural steel triangular frame that supports a 15m diameter rotor together with a turbine generator on each of the three corners.
The contractor will also be responsible for laying and connecting 1.2km of subsea cables.
After the 12-month test, the contractor will be responsible for the recovery of the generator and its return to shore.
