软刚臂结构形式对应FPSO吨位的适用范围

Application of Soft Yoke Structure Corresponding to FPSO

根据示范工程平台服役海域环境条件以及平台对系泊可靠性的要求,通过建立软刚臂单点系泊系统数学模型以及采用MATLAB软件进行数值计算,推导出系泊力、平台水平位移与软刚臂结构形式之间的关系;通过系泊力、平台水平位移的数值解,确定不同吨位的FPSO适用的最佳软刚臂结构形式,当FPSO吨位较大时,选取横舱式能较好地满足系泊要求;当FPSO吨位较小时,选取双瓶式结构较能满足系泊要求。

According to the environmental conditions in service area of the demonstration project platform and the requirements of the platform for the mooring reliability,the mathematical model of the single arm mooring system with soft Yoke and the software of MATLAB were used to study the relationship between mooring force,horizontal displacement of platform with the arm structural form of Yoke. According to the numerical results of the mooring force and horizontal displacement of the platform,the optimal soft Yoke structure for the different tonnage of FPSO was determined. When the tonnage of FPSO is large,the selection of transverse cabin can better meet the requirements of mooring; while the tonnage of FPSO is small,the selection of double-deck structure can satisfy the requirement of mooring.
