Book Description
Sea tests were conducted in May 1982 aboard the Dutch oceanographic research ship Hr. Ms. TYDEMAN to compare the performance of three wave buoys. These were a disposable buoy designed and built by the Delft Univ. of Technology, a WAVEC buoy under development by the Datawell Corp., and an ENDECO Corp. Wave-Track buoy owned by the David Taylor NSRDC. The disposable buoy provided energy spectra, while the other two buoys provided energy spectra and wave directionalities. Time histories of the significant wave heights and modal wave periods of the WAVEC and the Wave-Track buoys generally agree throughout the experiment. Energy spectra, mean wave directions, and spreading angles are also presented for most of the runs measured by the WAVEC and the Wave-Track buoys. The spectra of the two buoys are similar, with the WAVEC buoy showing higher peaks in a majority of cases. The mean directions basically compare well for wave frequencies above 0.11 hertz. Wave-Track mean directions below this range are often too sporadic for comparison with the WAVEC directions. The spreading of the Wave-Track directional energy is greater than the spreading of the WAVEC directional energy. Keywords: Directional ocean waves.
