Abstract
Many numerical methods have been developed to estimate wave response of moored floating body and applied in practical design. However, they need some assumptions for behavior of mooring chains and such assumptions were sometimes difficulty for practical application.
In this study, a new method is developed to solve such problem. The method can simulate detailed behavior of mooring chains with new chain models based on direct and physical phenomena compared with past models.
The developed method was applied to three different cases which have been investigated theoretically or experimentally. Simulated results were compared to these existing results, and the results showed that the present method can simulate well the behavior of a floating body moored by chains even the chains are grounding and/or slacking.
