Testing is facilitated by the R/V Henderson fully-mobile laboratory, which is housed at the University of Washington. This catamaran vessel, with a moon pool and specialized load-handling equipment, is equipped to test complete wave, current, and tidal current energy converters (WECs, CECs, and TECs) while monitoring system performance and environmental conditions in real time.
There are presently no permits in place for testing at this site.
Plans for PSTS include fixed moorings and pre-permitted tests for short-term – less than 30-day – experiments with small-scale (up to 10 kW) WECs using the R/V Henderson.
TEC and CEC testing capabilities are in development, with expectations for pre-permitted operations to be online in 2016 for short-term experiments. Tests of 1 m-scale prototypes suspended below the enclosed R/V Henderson barge moored in currents of up to 3 m/s will be possible.
Barge data acquisition capabilities will include power analysis and data acquisition in enclosed lab space and inflow/wake characterization using acoustic Doppler velocimeters positioned by a computer-controlled gantry.
Though without ocean swell, the Puget Sound Test Site offers significant fetch, resulting in localized waves. PSTS has almost 20 km fetch, resulting in up to 1 m waves at 4 s periods during storms. The depth of the shoal at this location is 20 m. At PSTS, wave conditions are characterized.
