|Abstract:||Nowadays, some floating structures with simple shapes such as barges near the reefs can be deployed as support bases. Unlike the open sea, the greatest feature of the marine environment near the island is the non-uniform complex seabed. In this paper, the hydroelastic analysis method with variable water depths is used to calculate the seakeeping of the floating structures, considering the uneven seabed as the boundary condition. Based on the three-dimensional hydroelasticity theory, the hydroelastic motion and response analysis of the barge is studied, coupled with parallel codes due to a lot of equations caused by the meshes. Considering different water depths and the complex bathymetry, the motion and loads of barge structures have been compared. The design wave parameters have been confirmed by the short-term forecast extreme results, and the whole stress distribution of barge structures near the reef has been shown plus modal stress by model summation. At last, strength evaluation of barge indicates that the effect of inhomogeneous seabed plays a large role in the arrangement of the barge near reefs and parallel calculations save the CPU time.|
