Offshore structures are subjected to dynamic environmental loads (wave and wind loads). A stress-life fatigue strength curve is proposed for tubular joints which in the splash zone area of offshore jacket structures. The Det Norske Veritas (DNV) standards given design T-curve air modified with environment-dependent parameters obtain this curve. Validity done by comparing lives experimental test...

The IEA Wind Task 30 OC4 (Offshore Code Comparison Collaboration Continuation) project was a continuation of the OC3 project of IEA Wind Task 23 Subtask 2, and was initiated due to the strong interest in continuing the work of OC3. The purpose of the project was to perform a benchmarking exercise of offshore wind turbine dynamics codes. OC4 consisted of two phases that were not considered in OC...

in this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. inducedseismic force is one of the most important excitations for the dynamic response of an offshore structure. according to api, seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...
