(一)随着南通、张家港和南京新生圩的对外开放,吃水10米以上的中外籍万吨级海轮进江艘数日益增多,由于白茆沙南水道的维护水深仅为理论深度基准面下7.1米,过往海轮必须候湖,有时还须过驳减载,损失了宝贵的运力。如要大幅度提高航道维护水深,在相当长一段时间内还难以实现。那末,可否通过开展咨询,优化调度,挖掘潜力来提高通航能力呢?回答应该是肯定的。 (1) With the opening up of Nantong, Zhangjiagang and Nanjing Xinshengwei, the number of 10,000-ton ships entering the country with more than 10 meters of draft is increasing. As the water depth of Baisha Shanan Channel is only under the theoretical depth reference 7.1 meters. In the past, the seagoing vessels had to wait for the lake. In some cases, they had to be overloaded and lost their load, losing valuable capacity. If it is to drastically improve waterway maintenance, it will be difficult to achieve for a long period of time. Then, can we improve the navigation capacity through consultation, optimization of scheduling and potential exploitation? The answer should be affirmative.
