Abstract

The development of new energy sources, such as oceanic wind power and photovoltaic system, has led to an increasing demand for dynamic sea cables. For the shallow water environment with large tidal range, it is prone to excessive bending,seabed interference, floating body interference and other phenomena, and it is easy to occur tension failure at the remote location. Combining the obvious water depth variation in the nearshore shallow water environment and the load capacity requirements of dynamic cables, a design method for floating photovoltaic pooling dynamic cable type is proposed, based on the suspension chain line equation to establish a slow wave dynamic cable line model. Combining with Orcaflex software to build a finite element model to design the dynamic cable preliminary scheme, considering the float offset, under the constraints to meet the shortest length of the cable as the optimization objective, using an improved simulated annealing algorithm to find the full tidal range of the cable, the preliminary scheme of the cable is optimized using a modified simulated annealing algorithm to find the global optimal solution. Combining with the analysis of actual engineering data in a certain sea area, the influence of the connection angle of the first end on the shape of the dynamic cable are analyzed when the cable length is fixed. The reliability of the optimized dynamic cable shape scheme and the feasibility of the method in this paper are verified using software.
