The Floating Production Systems (FPS) or the Floating, Storage and Offloading Systems (FPSO) have been applied to marginal oil fields or early production systems since late `70 in view of less capital and short delivery. There are two types of floating production systems: semi-submersible based spread mooring type and tanker-based single point mooring. This paper describes the analysis method, the technical development of optimization programs and the model experiments for the Single Point Mooring (SPM) systems for FPSO, which have been carried out as a joint research project by Japan National Oil Corporation, Akishima Laboratories Inc. and MODEC Inc. The detailed analysis program is developed based on the constraint matrix method in frequency and time domains and is capable of calculating the motions and constraint forces of SPM in wind, current and random waves. Outline of calculation method is presented.
