摘要

The paper described and evaluated a new method for calculating wave forces on offshore structures. It accounted for linear filtering of surface profile records into the frequency domain, superposition of Airy wavelets in the time domain, and stretching of crest kinematics, all essential elements of nonlinear dynamic analysis of deepwater structures. The accuracy of the method has been verified by comparison with measured hurricane-wave forces. Wheeler stretching, as it became known, is common practice today. This paper presented a new method for calculating ocean wave forces on offshore structures. It was based on data from two full-scale wave force measurement installations in the ocean and a mathematical model representing Morrison's hydrodynamic forces on submerged bodies in unsteady flow and Dean's kinematic flow field of highly nonlinear waves. The method was verified and forms the basis for offshore structure design in RP2A and all major analysis software.
