Abstract or Summary
  • The motions of a small spar buoy were measured in deep water. The measured variables were two buoy tilts, three accelerations, two wave slopes and the wave height. The variables were corrected for buoy motion and rotated to stationary coordinates, Fast Fourier Transformed, and analyzed spectrally. Analysis included power spectra, coherence, phase and transfer functions. It was found that the buoy was a surface follower at low frequencies up to the frequency of the peak of the wave spectrum. At higher sea wave frequencies, the buoy resists sea motion. The RMS tilts of the buoy are about 0.6 of the RMS sea slopes, and practically all of the buoy motion is concentrated in the frequency band from 0.1 to 0.3 Hertz.
