Wave conditions

Wave conditions in the test bed area are monitored in real time by a buoy called Las Palmas East, owned by the State Ports Authority. The buoy is located at the co-ordinates 28.05⁰N – 15.39⁰W, at a depth of 40 metres. The following link gives access to information in real time.

A Waverider, scalar buoy was installed from 1992 to January 2014 to record information on the height and period of the waves. The buoy was replaced in January 2014 with a Triaxys, directional buoy, thus allowing the direction of the wave action to be registered along with the other characteristic parameters.

Results

Below are some of the results arising from the analysis of the time series between February 1992 and September 2014 for the following characteristic wave parameters:

  • Significant height (Hs), in metres
  • Mean period (Tm), in seconds
  • Peak period (Tp), in seconds

With respect to the direction of the waves, the short period of measurements analysed, January 2014 – September 2014, shows a dominant wave direction from the NE sector as shown in the figure below.

Energy potential

The wave energy potential can be seen in the atlas drawn up by the Institute for Energy Diversification and Saving (IDAE) and the Institute of Environmental Hydraulics of Cantabria (IHCantabria). The following link will take you to the atlas.

Within the test bed area, the mean wave power is approximately 6 kW/m, with very little seasonal variability, allowing for testing of prototypes in controlled energy and not very extreme conditions throughout the year.
