SPRINGING AND SLOW-DRIFT RESPONSES: PREDICTED EXTREMES AND FATIGUE VS. SIMULATION

This study addresses statistical analysis of second-order load and response models of large-volume structures, such as tension-leg platforms (TLPs). A general statistical model is shown that directly estimates both extremes and fatigue of these load and response motions. It can be applied directly to an arbitrary second-order model: sum- plus difference frequency, first- plus second-order response. Extensive time-domain simulations are performed for verification. Two TLP applications are considered: a springing example of tether tension and fatigue, and a slow-drift example of extreme surge motions.
