Due to the increase of vessel numbers and the trend of large vessels,the dense in port anchorage is increasing rapidly. The increased incidents caused by anchor dragging result in great lose to many countries. Through the investigation and analysis into anchor dragging vessel) we find that they have a common problem, insufficient precaution during the course. There is no quantity management, no efficient monitor towards the state of anchored vessel. To solve the problem effectively, based on the adequate analysis of the force characteristics of anchor vessel, through the classification and analysis of the latest research both in China and abroad, and by learning lessons from some vessel tests, we work out several operating principles concerning related processing units, and finally finish the primary study in vessel anchor dragging early warning system.
