In response to the high density,various types and varying sizes of ships within Zhanjiang harbour bay,as well as the shortage of anchoring points,to scientifically plan the anchorage,on-site research is conducted on the anchorage demand and operation status of the Zhanjiang Port.Based on the classification of anchoring points,a calculation model is established to calculate the optimal number of anchoring points within Zhanjiang harbour bay using queuing theory,and based on the calculated anchorage demand,the short-term and long-term anchorage planning plans are proposed.Compared with the method of calculating the number of anchoring points without classificating the anchoring points,the anchoring requirements in Zhanjiang Harbor obtained in this paper are more in line with reality.The layout of the anchorage location is more reasonable,the functional division is more complete,and the anchoring safety is more guaranteed,which can reduce the waste of funds caused by excessive construction of the anchorage,and has significant social and economic benefits.
