船舶深水抛锚方法分析

Analysis of Anchor-Dropping Method in Deep Water

由于抛锚方案选择不当、抛锚方法应用不当等原因,极易出现抛锚安全问题,深水抛锚时容易出现出链速度太快刹不住而丢失锚链,深水起锚时由于出链太长容易出现锚机力量不够绞不起锚链而丢失锚链等事故。本文针对一起具体的深水抛锚丢锚事故,运用数理分析方法对船舶深水抛锚的动力学原理进行了分析,给出了2个极限水深的计算公式,对船舶深水安全抛锚提供了数理支持。

Safety problems emerge when dropping anchor in deep water due to improper dropping plan or method. Anchor may be lost because of uncontrolled fast dropping speed and insufficient power for the long chains when weighing anchor. Take an anchor loss accident as an example, using the mathematical and physical method to analyze its dynamic causes, the paper presents two formula calculations for calculating the limit of water depth as a reference for the safety of dropping anchor in deep water.
