Wave Site Data

The information on wave regimes comes from two Datawell Directional Waverider buoys located at the test berths. These continuously measure the sea state parameters (significant wave height, energy period, mean direction and wave power) as well as GPS position and sea surface temperature every half-hour.

A radio link provides a continuous feed from the buoy back to the main data centre. The data is recorded via the SCADA system and is available to each developer. The SCADA system also provides a drift alarm for each buoy, utilising the GPS information.

As well as monitoring marine conditions and the energy level of the sea, EMEC also has weather data from an onshore met station. Along with the measurement of electrical power supplied to the grid, EMEC can then assess the performance of a Wave Energy Converter.
