Wave Hub is a major marine renewables infra-structure project creating an electrical ‘socket’ on the seabed around 10 miles off the north coast of Cornwall in South West England. Wave Hub is to be connected to the National Grid via a subsea cable and will have an initial capacity of 20MW with the potential to scale up to 50MW in the future.
 The scope awarded to JDR includes the 25km 33kV subsea export cable which will provide the essential export link between the Wave Hub and the onshore control room at Hayle. JDR will also supply all subsea cables, connectors and the 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. Under development by the South West RDA (Regional Development Agency), the Wave Hub Renewable Energy Project will create the world’s largest offshore wave energy test centre providing the electrical infrastructure necessary to connect Wave Energy Converter (WEC) devices to the local power grid in North Cornwall.
Once connected, WEC Operators will have the opportunity to test an array of full scale wave energy devices over several years in a realistic, fully monitored marine environment.
The Wave Hub system comprises an 8km2 offshore WEC berthing area in around 50m of water. The berthing area offers four discreet segments each with the potential for single WEC Operator occupation, linking their individual device arrays to the system by means of a cable riser connected to one of four 33kV 3 phase Wave Hub Tails tied back to the Wave Hub Chamber.
 JDR will provide these Tails, complete with custom-engineered Dry Mate Connectors providing compact electrical and fibre optic connections.
JDR’s purpose designed Wave Hub Chamber provides a watertight connection between the Wave Hub Tails and the main cable. Within the chamber, the main cable is terminated onto two isolated busbars and fibre optic cables split out to link with those running to each WEC via the integrated Tails and riser cables.
JDR will also deliver the 25km main subsea export cable which consists of twin 300mm2 33kV triads and fibre optic cables, linking the Wave Hub system to the onshore grid network.
Custom-engineered by JDR, this project draws on a wealth of experience in the design and manufacture of subsea cables and umbilical systems to deliver a solution that will meet the demanding requirements of this innovative application. JDR’s quayside facility at Hartlepool dock is ideally sized for the manufacture and load-out of this 1500 tonne cable system, with installation and commissioning supported by JDR’s team of qualified offshore service technicians.
