abstract

  • Copyright 1990, Offshore Technology Conference. Increased attention has recently been focused on determination and reproduction of realistic properties of extreme sea waves for use in numerical and physical modeling and design load computations. Results of recent research on laboratory synthesis of extreme waves and experimental investigation of wave-fluid particle kinematics just prior to breaking using laser Doppler anemometry is presented. An extreme transient wave, similar to those found in hurricane Camille, and an "equivalent" regular Stokes wave often used for design purposes were generated, and their kinematics measured. Due to particular asymmetries not present in the Stokes wave, the transient wave kinematics under the crest are shown to be much more severe above the still water level and somewhat less severe below. This comparison suggests that it would be worthwhile to further investigate the use of extreme, transient waves as new, more realistic design waves.
