Dynamic response of moored semi-submersible platforms to non-collinear wave, wind and current loading
- Univ. of Glasgow (United Kingdom). Dept. of Naval Architecture and Ocean Engineering
The authors of this paper developed a non-linear time domain analysis procedure and calculation tools based on these procedures to predict the motion response of moored semi-submersibles under wave, wind and current loading. These tools have been validated with published results. In the first part of the paper a brief summary of the nonlinear analysis procedures is given, together with some results obtained from theoretical results. In the second part of the paper the results of parametric studies investigating the effects of variations in external wave, wind and current force magnitudes and directions on the dynamic motion response of semi-submersible platforms are illustrated. These results show the sensitivity of certain types of response values as the external forces vary in magnitude and in direction. Such results provide essential information for probability based design procedures. In the last part of the paper, time domain models are used to simulate the incidents occurred in the North Sea in 1990, in which mooring lines of some semi-submersibles were failed.
