TEAMER Description Alden has unique facilities to help developers test and improve their wave energy conversion equipment. Combined wave and wind loading as well as mooring techniques can be evaluated for wave energy capture systems on scaled models. Both linear and basin type wave tanks are available, as well as onsite field measurement services to provide bathymetry, wave height and direction measurements, current velocity measurements, water and tide level data acquisition, sediment-water interface monitoring, and biological surveys. Wave energy conversion systems have been tested at Alden since the 1980’s.

Specializations, Capabilities, and Key
Facility Attributes Not Covered Elsewhere
This is a recirculating flume facility, so a constant velocity can be maintained indefinitely. This allows collection of a much greater amount of data than possible in tow tanks. Alden's biologists are highly experienced in assessing the impacts of generation devices on fish and the facilities allow for accurate testing with fish in a highly controlled environment.
