Abstract
Examinations are made of the dynamic effects associated with modal responses of deep‐water, wave‐excited offshore structures. Such examinations are intended to assess the influences that variations in several parameters involved have on the dynamic structural response. Variations in the following parameters are considered: the distributions of the structural volume and projected area, the distributions of the inertia and drag force coefficients, the relative magnitude of the inertia and drag force components, the natural modes of vibration of the structure, and the random phase angles used for the generation of the wave loading. The response is examined for a wide range of values of the natural frequencies of the system, and the relative importance of the effects of changes in the parameters considered is elucidated. The results of the study provide valuable insight into the response of offshore structures to wave forces, and may contribute to forming a basis for the development of future, efficient desig...
