Modeling and Assessment of the Xijiang FPSO Turret Mooring System

This paper uses the information of the Xijiang floating production storage and offloading (FPSO) mooring system coupled with dynamic analysis of the system to generate scenarios for the most likely causes of the damage to the wires and predict if this is likely to result in further progressive damage of the mooring system. The modeling reflects the fundamentals of the Xijiang FPSO mooring system and can be used to further investigate potential causes for the mooring leg damage. The mooring dynamic analysis has been used to investigate the indicative behavior of the mooring lines under various conditions when Buoyant Turret Mooring (BTM) is connected. The model has been used to investigate the tensions, bending moments and bending radiuses near the lower socket. Further more the models have been checked to determine that they produce results of the correct order for the mooring system.
