近浅海单点浮筒式系泊系统的部分参数设计

A Parameter Design of a Single Point Buoy Type Mooring System near Shallow Sea

研究了系泊系统参数的设计问题。首先对系泊系统中锚链、钢桶和重物球、钢管、浮标这四个部分单独进行受力分析与力矩分析,建立受力平衡方程与力矩平衡方程;然后得出浮标深度和锚链左端点切线的水平夹角相关的两个表达式;最后利用matlab软件编程求出:海面风速为36 m/s时,钢桶的倾斜角为7.8566?,四段钢管的倾斜角度分别为:7.6962?, 7.6557?, 7.6156?, 7.5759?,浮标吃水深度为0.7810米,游动区域的面积为951.246 m2。此外,还讨论了如何对重物球质量进行调节可以使得钢桶的倾斜角小于5?。

This paper focuses on the studies of mooring system parameters’design.Firstly,the force analysis and torque analysis of the anchor chain,steel drum and heavy ball,steel pipe and buoy in the mooring system are carried out respectively.And the force balance equation and the moment balance equation are established.Then the buoy depth and the anchor chain are obtained,and the two expressions related to the horizontal angle of the left end tangent are finally obtained by MATLAB.The following results are obtained when the sea surface wind speed is 36.The inclination angle of the steel drum is 7.8566,the inclination angles of the four sections are 7.6962,7.6557,7.6156 and 7.5759,the draught-depth of the buoy is 0.7810 meters,and the area is 951.246.In ad-dition,it is also discussed how to adjust the weight of the heavy ball such that the tilt angle of the steel drum is less than 5.
