Abstract:

For the very large floating structure (VLFS) which is deployed near coasts, islands and reefs, the encounter wave conditions will become extremely complex. Therefore, the traditional methods with uniform wave inputs cannot be applied to the hydroelastic analysis of VLFS near coasts, islands and reefs. The actual wave condition in different modules, i.e. the non-uniform incident waves should be considered. Taking into account the effect of non-uniform incident waves, a new analysis procedure THAFTS-NUIW is developed based on the classical three-dimensional hydroelasticity theory. The motion and connector loads of VLFS in the non-uniform regular and irregular waves are studied. Compared with the results calculated by traditional method, significant differences can be found in the hydroelastic results. The theory and results presented in the paper provide a technical foundation for the load determination and structure design of VLFS (including connectors) near coasts, islands and reefs.
