摘要
目的紧密结合近浅海观测网传输节点中系泊系统的实际工作特点和相关数据信息,分析系泊系统各组成部分的物理结构和数据信息。方法运用常微分方程理论、力学动态平衡原理、动态规划模型以及理论分析与数值计算等研究方法,在不同的海况环境下,确定锚链的型号、长度和重物球的质量。结果当海面风速为12m·s-1时,钢桶的倾斜角度为1.15°;锚链中有15.28m悬挂于钢桶上,连接锚的剩余15.28m锚链平躺在海床上,浮标的吃水深度为0.748 8m,浮标的游动区域的半径为17.66m2。当海面风速为24m·s-1时,钢桶的倾斜角度为4.56°;锚链中有19.73m悬挂于钢桶上,连接锚的剩余3.32m锚链平躺在海床上,浮标的吃水深度为0.701 2m,浮标的游动区域的半径为17.85m2。当海域的水深介于16~20m之间、海水速度介于0~1.5m·s-1、风速度介于0~36m·s-1时,钢桶的倾斜角度介于0°~7.88°,由上向下的四节钢管的倾斜角度范围依次为:0°~3.49°、0°~4.66°、0°~5.72°和0°~6.07°;浮标的吃水深度介于0.116 3~1.557m,浮标的游动区域面积介于0~684.53m2。结论对于海域水深、海水速度和风速度的其他情况下,运用相同的分析方法可以在不同海况下去确定系泊系统,使得浮标的吃水深度和游动区域及钢桶的倾斜角度尽可能小,起到抵御外界环境的作用,保证正常钻井作业的安全。
Objective The actual work characteristics and relevant data information of the mooring system in the transmission nodes of the shallow sea observation network are closely combined to analyze the physical structure and data information of each component of the mooring system.Methods Using the methods of ordinary differential equations,dynamic equilibrium of mechanics,dynamic programming model,and theoretical analysis and numerical calculations,the type,length,and weight of heavy chain cables are determined in different sea conditions.Results When the sea surface wind speed is 12 m/s,the inclination angle of the steel drum is 1.15 degrees;15.28 mof the anchor chain is hung on the steel drum,and the remaining 15.28 manchor chain of the anchor is lying on the seabed;the draft of the buoy is0.7488 m,the radius of the floating area of the buoy is 17.66 m^2;when the sea surface wind speed is 24 m/s,the inclination angle of the steel drum is 4.56 degrees;19.73 min the chain chain is hung on the steel drum,and the remaining 3.32 manchor of the connection anchor The chain lies flat on the sea floor;the draft of the buoy is 0.7012 m,the radius of the buoy＇s swimming area is 17.85 m^2;when the water depth of the sea is between 16 m-20 m,the seawater speed is between 0-1.5 m/s,the wind When the speed is between 0-36 m/s,the tilt angle of the steel drum is between 0-7.88 degrees;the tilt angle range of the up and down four steel pipes is 0-3.49 degrees,0-4.66 degrees,0-5.72.Degree and 0-6.07 degrees;the depth of draught of the buoy is between 0.1163 m-1.557 m,and the area of the buoy＇s swimming area is between 0-684.53 m^2.Conclusion For other conditions such as sea water depth,seawater speed and wind speed,the same analysis method can be used to determine the mooring system in different sea conditions,so that the draft depth of the buoy and the tilt angle of the swimming area and the steel drum are as small as possible.To resist the external environment and ensure the safety of normal drilling operations.
