On irregular, nonlinear waves in a spread sea
- Shell Research B.V., Rijswijk (Netherlands)
Optimal design and reassessment of offshore structures requires a good understanding of the ocean environment. The motion of the sea surface can be viewed as a three-dimensional, nonlinear stochastic process in time. In order to characterize the wave environment adequately, the authors need to model its random, nonlinear, and spread nature. In this paper, they address: the expected shape of a wave near a crest or trough, the expected shape of the ocean surface at one point, given a crest at a different point, an efficient method to incorporate nonlinear effects within linear wave simulations; and the magnitude of wave nonlinearity as a function of wave amplitude. Detailed comparison of theory and full-scale offshore measurements at the Shell Expro Tern platform show good agreement.
