Wave Hub is a major marine renewables infrastructure project that will create an electrical ‘socket’ on the seabed in some 50 metres of water around 10 miles off the coast of Cornwall in South West England and connected to the National Grid via a subsea cable. Wave Hub will have an initial maximum capacity of 20 MW (enough electricity to power approximately 7,000 homes) but has been designed with the potential to scale up to 50MW in the future.
The scope awarded to JDR includes 25 km of 33 kV three-phase power cables that will provide the essential link between the Wave Hub and the onshore control room. The Wave Energy Convertors are connected back to the Wave Hub by four additional 300 m three-phase power cables and dry mate connector sets. All cables include fibre optics and will be subject to rigorous integration testing. JDR will also supply the 'Wave Hub' assembly consisting of subsea terminations and a complete subsea protection structure. The package of equipment will be delivered in the second quarter of 2010 from JDR's new deepwater quayside facility at Hartlepool Dock. The first wave energy devices are expected to be deployed in 2011.
