摘要：

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.
