基于锚链状态监测的锚泊安全评估

Assessment of anchoring safety based on the watching condition of anchor chain

针对锚泊船在强风中容易走锚的情况,提出了根据锚泊船锚链受力状况,对锚泊状态做出分析的一种安全评估方法.对锚链的监测主要是观测锚链在锚链筒处与铅垂线的夹角,据此可以估算出锚泊船所受到的外力大小.然后将外力与锚泊力进行比较,从而可以判断出锚泊船是否处于安全状态.

Considering the fact that an anchoring ship is very easy to drag its anchor under strong wind, an assessment method of anchoring safety based on the condition of anchor cable at hawse pipe is presented in order to prevent the vessel from dragging its anchor. The condition of anchor cable at hawse pipe means the angle that the chain stretch from the perpendicular, from which the forces acted by wind or wave or current can be calculated. Then the anchoring ship may be judged whether safe or not by comparing the anchoring force with that acted on the hull.
