| Summary: | "Stretching" and Linear Extrapolation) and compared with the and predicted responses using kinematics calculated from the been proven to be more accurate and reliable for the calibrated by an analytical (linear) solution and measured computed from the conventional Morison Equation evaluating controversial results have recently motivated the development corresponding laboratory measurements. The wave forces were elevation, kinematics and evolution. This methodology has empirical and semi-empirical modifications of Linear (random) estimated using three methods (Hybrid Wave Model, Wheeler estimation methods can change significantly. The sometimes estimations of wave kinematics, but its impact on the frequency wave excitations, which are mainly due to the wave- Hybrid Wave Model showed excellent agreement, specially for investigated. In this study, the performance of the new low frequency (peak) responses of these deep-water offshore measurements. A numerical scheme based on a Finite Element methodology arid other methods currently used for kinematics non-linear effect of the wave-wave interactions on wave of a new methodology for wave kinematics prediction. While on linear modifications rendered poor underestimations. The prediction of the structural response is yet to be prediction was tested. The (surge) response of two offshore responses for regular waves. The comparisons between measured structures designed specially for deep-oil production was structures were found to be greatly dominated by very low the ambient wave kinematics from the wave elevation the low frequency components, while those using methods based the methods commonly used by the offshore industry are The predicted responses of an offshore structure when the the principles of hydrodynamics and explicitly considers the the response evaluation after it had been validated and time integration technique (Newmark-beta method) was used for wave induced kinematics are computed from different wave interactions. Wave Theory, the new approach (Hybrid Wave Model) satisfies |
