Reservoir

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.

• Measuring equipment– Pressure transducers– Accelerometers– Force transducers– Movement transducers– Strain gauges

• Online monitoring– Performance, WebCams, weather

Wave Dragon prototypeRTD activities

• WD prototype fully equipped– Turbines 1+6+3– Grid connected generators– Floating level control system

• Two different test sites– Close to Danish Wave Power

Association's test site– Further south-east where more

wave energy is available

Site selection Wales





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.



WD







ConstructionThe Wave Dragon unit will be constructed at a port, close to the deployment site. The manufacturing of the reinforced concrete structure is straight forward using standard methods from the civil engineering field.

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.

Wave Dragon - Perspectives

• A power plant size solution for exploiting offshore wave energy– Made up of proven technologies– Unique design and construction – Patented

• Single unit size from 4 MW to 11 MW with power generating capacity of up to 30 GWh/year

• Power plant capacity 4 MW – 1,100 MW (100 units example) • Long term installation cost < € 1,500 per kW by 2011• Long term power generating cost of 3,5 – 4,3 €c/kWh by 2011
