FPSO MODEL TESTS AND ANALYTICAL CORRELATION

This paper presents model test and analytical correlation results of a single point moored Floating Production, Storage and Offloading tanker based system (FPSO). Both Permanent and Disconnectable turret mooring system are considered. Analytical calculation of green water effects, vessel motions, turret and mooring line loads are compared with model test results. Frequency and time domain analysis techniques of calculating line tensions are demonstrated and results are compared to the model tests measured time histories. The analysis procedure discussed in this paper is aimed toward estimating 1) motions at bow relative to the water surface, 2) mooring line tensions and 3) turret design loads for a turret moored FPSO with a reasonable degree of accuracy. It is demonstrated that mooring line tensions domain computer simulation of the line dynamics provided the input fairlead motions are correct. Thus the method of computing time histories of mooring line tensions based on free-floating vessel motions is applicable for other spread moored floating systems in the same range of water depth.dynamic analysis
