Summary:
The main aim of the tests was to provide data for the validation of numerical models of the device and mooring components and device motion and power interactions when moored in closely spaced arrays; the tests were not intended to be proof-of -concept tests for a particular device and none of the tests were intended to study survival response under extreme loading.
Tests were completed at 1/20 scale on a single OWC device and on close-packed arrays of three and five devices following calibration of instrumentation and the wave and current test environment. One WEC was fully instrumented with mooring line load cells, optical motion tracker and accelerometers and tested in regular waves, short-and long-crested irregular waves and current. The wave and current test regimes were measured by six wave probes and a current meter. Arrays of three and five similar WECs, with identical mooring systems, were tested under similar environmental loading with partial monitoring of mooring forces and motions. A total of ninety-five tests were undertaken including wave and current calibrations and damping tests.
Preliminary analysis of the data indicates that close –packed arrays of energy converters may be more efficient in energy capture that the same number of similar devices.
