水下软刚臂单点系泊研究

针对渤海浅水边际油田开采工程,提出一种可调节系泊臂铰接点高度的水下软刚臂(YOKE)单点系泊方案,无水上系泊塔,将军柱在水下,可根据作业水深调节系泊臂与船艏系泊支架的铰接点,能反复利用。水动力分析、数值计算和模型试验结果显示:数值计算和模型试验数据接近,系泊力和纵荡的误差在合理范围内,表明系泊方案计算合理。

Research on Single Point Mooring of Underwater Soft YOKE

With regard to the exploitation of shallow water marginal oil fields in Bohai , a underwater soft YOKE single point mooring （ SPM） mode was proposed , whose universal joint （ u-joint ） on mooring arm is adjustable .The design with kingpost moved underwater and abovewater mooring tower removed , is capable of adjusting the mooring arm u-joint connected to bow sup-port structure according to the working depth and can be reused .This design undergone hydrodynamic analysis , numerical calcu-lation and model test .The result illustrates that numerical calculation data is very close to test data , the errors of mooring force and surge motion is in a reasonable range , showing that the calculation method is valid .
