The present design method for calculating the extreme loading on offshore structures uses what is termed the 'design wave.' This is an extreme wave and is usually chosen as the highest wave likely to occur within a given period. Based on their observations made during experimental research on wave breaking, the authors raise two criticisms pertaining to this method: (1) the observed height at which wave breaking occurs is often substantially below that suggested in design codes, and hence offshore structures may be designed to withstand waves that can never physically exist; and (2) models used to predict kinematics for the design waves are inadequate in their descriptions of velocities in the high crest region, which could lead to serious local under-design.
