MEASUREMENT OF WAVE PROPERTIES IN EXTREME SEAS DURING THE WADIC EXPERIMENT

The primary objective of the Wave Direction Measurement Calibration Project (WADIC) was to evaluate operational, commercially available directional wave measurement systems under severe open ocean wave conditions. Two methods for in situ measurements of ocean waves were employed: fixed platforms using wavestaffs, pressure transducers, current meters, lasers, etc., and moored buoys. Wave induced orbital velocities and associated wave profiles are of considerable interest in the design analysis of offshore installations and of the operability and stability of ships, in particular under high wave conditions. The WADIC field experiment resulted in some unique measurements of wave properties in sea states up to nearly 11m (36 ft) significant, and single waves as high as 20m (65 ft). This paper focuses on two aspects: first, on the analysis of parameters defining the asymmetry of extreme and steep waves as seen from fixed and moored sensors, and, secondly, on comparisons of measured storm wave orbital velocities with predictions and simulations based on directional linear wave theory.
