软刚臂系泊系统水平系泊力原型测量方法

Prototype Measurement Methods for Horizontal Mooring Force of Soft Yoke Mooring System

以渤海某在役的浮式储油卸油装置(FPSO)软刚臂为研究对象,对其系泊力的测量方法从应变、位移和运动姿态3个方面进行了讨论,并对测量的精度及准确性进行了分析.结果表明,3种方法在测量精度上大体相同,而长期稳定性和成本上倾角仪(运动姿态)方法要好于其他两者.系泊力原型测量方法的应用,不但可以使作业者有效保障现役FPSO的系泊安全,而且其测力结果亦可作为软刚臂系泊性能评估的重要参考.

Abstract： The horizontal monitoring force methods were discussed from the strain, displacement response and motion attitude based on an on-site soft yoke mooring system of FPSO in service in Bohai Bay. The precision and accuracy of the three methods were also analyzed. The results show that the three methods have approximately the same precision, and the motion-based inclinometers are more stable and inexpen- sive than the others. In general, the present work can not only ensure the safty of the mooring system of FPSO, but also provide important reference for performance evaluation of soft yoke mooring system.
