Based on the finite water depth Green function, Morison equation and coupled dynamic analysis method, dynamic response analysis was performed for a platform in shallow water with different types of mooring systems. The results show that traditional catenary or taut mooring systems, usually adopted for medium or deep water depth, will encounter a range of problems in very shallow water near islands and reefs, and the room for further optimization is very limited. However, the pile anchor chain hybrid mooring system proposed in this paper can overcome these problems, and at the same time, makes ship docking much more convenient. The analysis results in this paper have certain guiding significance for model tests and further design of mooring systems in very shallow water.
