..., detailed reviews of existing video inspection data were undertaken. These reviews identified separate high frequency mooring system dynamic responses in frequency ranges higher than typical wave frequency responses. In relatively benign conditions associated with ROV-based inspection activities, torsional...

... of a simplified correction formulation. Based on the results presented herein, one such method is proposed. Analysis Methodology The evaluation of the quasi-static wave loading and the dynamic response of a jack-up requires computation of the water particle kinematics at each leg in the time domain, extending...

... indicates that even for a regular wave, higher harmonic components are present due to non-linearities. Therefore, SDOF method severely overestimates the inertia forces near the natural period, while possibly underestimating the dynamic response further away. This paper recommends a practical frequency...

Introduction Most analyses of the dynamic response of an offshore structure to wave loads are based on the linear wave theory, in which the effects of the water surface elevation on the offshore structure are neglected. However, in reality the waves are splashed over the portion...

Under these circumstances the normal code checks which are stress related may no longer be appropriate. If the dynamic response of the structural system, plastic deformation and strain...

In the first stage, the measurements showed that the sandy soil affords significantly more structural resistance, or "spud can fixity", than is assumed in the typical "pinned" spud can model. A calibrated structural model was devel- oped to incorporate direct measures of spud can fixity...
