Waves overtopping the doubly curved ramp

The Wave Dragon is a slack-moored wave energy converter that can be deployed alone or in parks wherever a sufficient wave climate and a water

depth of more than 20 m is found.

LocationThe demonstrator device will be located

2 - 3 miles off the South West Wales

coast, off St Ann’s Head.

The site has been selected to be:

• Exposed to the predominant wind/wave direction

• Relatively close to land, for economic and operational purposes

• Away from commercial shipping interests

• Close to a major port, Milford Haven

• Close to potential grid connection locations (Dale, Marloes)

Due to these practical reasons, the demonstration site is located within the Pembrokeshire Marine SAC (Special Area of Conservation), and a full Environmental Impact Assessment is being conducted. The area marked with the black square on the map shows the area being investigated - the area occupied by the Wave Dragon device is much smaller.

MooringA catenary mooring solution is considered the only feasible option because of its ability to absorb large peak loads. Design and construction of large offshore foundations, sub sea installations and handling of heavy components and equipment is a well established discipline within the offshore wind, oil and gas industries.
