Airgap prediction from second-order diffraction and Stokes theory | Academic Article individual record

The airgap of a specific semisubmersible platform subjected to irregular waves is considered. Detailed model test results for both motions and airgap time histories are used to verify analysis results. The effects of various methods of including second-order diffraction contributions are demonstrated. A new method is proposed for use in post-processing second-order hydrodynamic transfer functions in which those transfer functions that are unavailable or believed to be unreliable are replaced with those of an undisturbed second-order Stokes wave.
