视觉信号是船舶必须配备的求救信号,但是对于特种船,使用方法不当,会引发船舶灾难。此文通过对特种船溢货(气)环境的分析,讨论了特种船上视觉信号的使用方法。 The visual signal is a distress signal that the ship must be equipped with, but for a special type of vessel it is improperly used and can cause a ship disaster. Through the analysis of the special vessel overflow (gas) environment, this paper discusses the method of using visual signals on special vessels.
