摘要：

本文提出了单点系泊防碰圈的计算模型。利用曲梁理论分析两辐条间外缘圈的变形与内力,进而由边界条件与连续条件获得了防碰圈的理论解。文末以南海涠10—3油田单点系泊防碰圈为例,详细地分析了防碰圈系统的內力与变形随辐条预紧力的变化关系?峁砻麂?0—3油田单点系泊防碰圈多次发生的辐条破断事故可能是由于辐条预紧力不够合理造成的。

Abstract:

This paper puts forward the calculating model of Single point Mooring (SPM) anticollision ring, analyzes the deformation and internal forces of the outer edge between two spokes by means of curved beam theory, therefore gets the theoretical solution of the anticollision ring by boundary and continuous conditions. Finally, the paper takes the SPM anticollision ring of wei 10—3 field in South China Sea as an example, analyzes in detail the changing relations of the internal forces and deformation of anticollision ring with pre一tighting forces of the spokes.The results show that spoke fracturing accidents of the SPM anticollision ring of wei 10一3 field results from the unreasonable pre一tighting force of the spokes.

Key words: Single point mooring, Anticoilision ring, Curved beam theory
