| description | For the first phase of this research a six degree of freedom frequency
domain model of a Tension Leg Platform (TLP), which includes the
effects of non-collinear wind, wave and current, has been developed to
determine the extreme response and sensitivities of environmental
input. The model includes the steady forcing effects due to current and
wave interaction, wind and wave drift. The dynamic "effects include
Morison type forces due to inertia and drag, spatially correlated wind
and slowly varying wave drift. The response model is used to evaluate
four limit states of a TLP, namely minimum and maximum tension,
maximum offset and minimum airgap. The second phase of this
research has developed a method to evaluate the return period of
required response and then select the mostly likely combination of
environmental parameters to aid in design screening. The technique
combines the response model and Inverse First Order Reliability
Method (FORM) through a non-linear optimization routine. |
