abstract
In this paper, the second-order double-frequency wave loads on the ISSC TLP in regular waves are investigated. The second-order wave loads on the actual compliant TLP are compares with those on the stationary TLP in order to see the effect of body motions. A higher-order boundary element method (HOBEM) is used for the computation of the first- and second-order hydrodynamic quantities. Particularly, the capability of HOBEM in calculating the second spatial derivatives on the body surface is demonstrated. the numerical results for the stationary ISSC TLP are compared with Matsui's experimental results, and reasonably good agreement is observed.
