小型海船锚系布置快速性设计方法研究

由于《海船艏锚泊设计导则》(CB/Z 280-2011)只适用于载重2 000 t以上的钢质海船,未对小型海船的锚泊设计提出指导,故小型海船的锚泊设计需另寻方法。在总结小型海船锚系布置设计特点的基础上,针对小型海船锚链筒的布置即使反复调整其空间位置也难以满足对其长度的要求等问题,通过对锚链筒位置的几何模型进行分析,采用解析几何法解决了锚链筒的定位;基于CAD二次开发,实现了锚链筒最优位置确定。经验证,该方法速度快,能满足小型海船锚系布置的要求。

Anchoring Arrangement Design for Small Seagoing Ships Based on Fast Method

As Chinese ship design guideline for seagoing vessel’s bow anchoring CB/Z 280-2011 only applies to steel seagoing ship with 2 000 DWT and above,thus it’s necessary to find new design rules for those volumes less than 2 000 DWT.This paper summarized the characteristics of anchor equipment arrangement on small seagoing ships and found that even the spatial location were adjusted many times,it was still hard to meet the length demand of hawse pipe.Thus the paper proposed a method to determine the location by analytic geometry,after analyzing the geometric model of hawse pipe.Based on the secondary development of CAD,the optimum arrangement of hawse pipe was carried out.It is validated that the proposed method can effectively meet requirements of the anchoring arrangement in practice.
