Vessel/mooring/riser coupled dynamic analysis of a turret-moored FPSO compared with OTRC experiment

The system's stiffness and line tension as well as natural periods and damping obtained from the OTRC measurement reasonably match with numerically simulated static-offset and free-decay tests. The numerically predicted global vessel motions are also in good agreement with the measurements. It is underscored that the dynamic mooring tension can be underestimated when truncated mooring system is used.
