Hydrodynamic evaluation for spar platform subjected to mooring line failure
The changes of dynamic response for a spar platform due to mooring lines failure are evaluated. The wave and low frequency responses are displayed in motion and tension spectrums. The development of the hydrodynamic behaviour subjected to the heaviest load on the mooring lines is quantitatively assessed by comparing response spectrums and statistical results. It is shown that the changes vary greatly for different structure motions and line tensions under various environment loads or line failure situations, though the dynamic responses tend to increase significantly.

Abstract

The changes of dynamic response for a spar platform due to mooring lines failure are evaluated. The wave and low frequency responses are displayed in motion and tension spectrums. The development of the hydrodynamic behaviour subjected to the heaviest load on the mooring lines is quantitatively assessed by comparing response spectrums and statistical results. It is shown that the changes vary greatly for different structure motions and line tensions under various environment loads or line failure situations, though the dynamic responses tend to increase significantly.
