Abstract

In this paper, the theory of progressive ocean-surface gravity-waves is discussed, followed by the concept of the representation of the irregular sea-state by a sea-spectrum. Fourier series decomposition of the irregular sea-surface into its constituent regular waves and the method of realizing unique time-records of the sea-surface-elevation from commonly used sea-spectra is described. A detailed description of the development of Modelica componentmodels to generate regular as well as irregular waves, and depth-varying current, with an eye on the requirements imposed by probable integrated simulation scenarios, is then presented and the results discussed.
