An optimization program for single point mooring floating production systems, which are currently employed for marginal offshore oil field, was developed. This program is applicable for typical six kinds of single point mooring systems, i.e., CALM-Yoke type, Turret Mooring type, SALM hawser type, Articulated Column-Yoke type, SALS type, and Tower Soft Yoke type.Type program contains detail analysis programs and simplified optimization program. The detail analysis programs are developed based on the up-to-data theory and are capable of performing dynamic and static analysis of mooring system and flexible riser, vibration and fatigue analysis of mooring chain, downtime analysis of floating production system and other analysis. These functions were verified by using model test results and full-scale test results. Some results are presented.The simplified optimization program was developed for preliminary evaluation of mooring system for a specific oil field. Using the detail analysis programs, a series of calculation was carried out and the results were compiled as built-in database, which contributes to shor-ter calculation time. By using this program, the optimized dimensions of mooring system will be derived from the input of water depth, environmental data, and storage capacity.
