A unique multiple-spar buoy for measurement of directional wave spectra
and meteorological parameters. The buoy consists of a 15m branched aluminum structure.
5 individual 8.5" tubes pierce the water surface to provide a spar-like open
structure for the measurement of small waves usign capacitance wires. The buoy
is highly-damped in heave, pitch, and roll, and behaves as a wave follower for
long waves. The sum of buoy motion and wave wire measurements provide for directional
measurement of waves over the full spectrum.
The design required careful
attention to weight and balance in order to achieve the desired hydrostatic characteristics,
but also emphasized simple detailing for ease of manufacture and modularity. The
buoy is designed to be disassembled for shipping with relative ease.
