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

Abstract

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 inexpensive 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.

Key words: floating production storage and offloading(FPSO), soft yoke mooring system, horizontal mooring force, field measurement
