Abstract

The design and analysis of mooring system, which would probably affect the safety of operation, are important for an offshore platform. Previous studies mostly concern about the case in deep water. A rectangle-FPSO operating in extremely shallow water is considered in this paper. Dynamic analysis to reach cable tension and vessel offset is carried out. Comparison between two different kinds of mooring systems is presented as well. Further, cable tension in the survival condition is checked according to API rules and whether the FPSO would hit the seabed is also verified. At last, a reasonable design proposal is given. The analysis is carried out based on three-dimensional potential flow theory. Full QTF if necessary in shallow water and is solved. Cable dynamics are dealt with FEM method. Results show that polyester cables are superior in shallow water.
