- 摘要：
- Due to the complexity of the marine environment loading and motions of vessels, many uncertainties are involved in the design of mooring systems. This paper designs a fully monitoring system, including meteorological-environmental and mechanical aspects. The environmental monitoring system is composed of current, wave and wind equipments. Fiber Bragg Gauges/FBG, incline sensors and GPS/INS form the mechanical monitoring system. On the basis of dynamic characteristic of the soft yoke system, a restore force measurement method has been proposed according to the response of the angular information of the soft yoke. The monitoring system has been installed on one FPSO in Bohai Bay, and comprehensive monitoring information has been obtained from 2011. The calculation of the restoration force of the mooring system by the present dynamic method shows high agreements with that of the FBG. The vessel motions in the frequency domain calculated by the measured wave spectrum multiplied by the designed RAO (Response Amplitude Operator) are compared with the in-site monitoring motions. The results of comparisons show the feasibility of the present monitoring system in safety assessments of FPSO and SYMs. (C) 2015 Elsevier Ltd. All rights reserved.
