Wave Directional and Amplitude Measuring Buoy: Wadibuoy

To measure wave direction and amplitude has always been of a particular interest for scientists and meteorologists. The knowledge of the direction of the energy contained in the waves at specific frequencies is a very important para meter for offshore structure model designers in order to reduce the costs. Cnexo and Nereides have been developing and testing for four years a complete system to measure waves directions and amplitudes from data radiotransmitted from a moored buoy. We would like to present some of the configurations we have been using in several sea state conditions. Buoys have been moored in Atlantic Ocean, Pacific Ocean, NorthSea, Davis Straight and Mediterranean Sea. Several samples of the data processed might also be presented as well as the latest options which will soon be intro duced in the market by Nereides. Since its creation in 1971, a bit more than a decade ago, Nereides has been interested in waves measurement.
