宁波-舟山港蛇移门40万t航道工程设计

Design of Sheyimen 400,000 DWT Channel of Ningbo-Zhoushan Port

蛇移门航道位于宁波-舟山港北部海域,采用世界最大的矿石船作为设计船型,是我国第一条设计建成并投入运营的40万t航道。受周边岛礁和港口布局等限制,航道水流条件复杂,船舶航行及靠泊条件差,所在海域为舟山通航条件最为复杂的水域之一,航道设计难度大。经综合分析航道特点及难点,提出合理的船舶交通流组织和通航方式,结合船模试验进一步优化航道设计方案,经理论计算和实船通航分析确定船舶通航窗口期,并给出试运行期实时潮流监测方案。

Sheyimen Channel is located in the northern sea area of Ningbo-Zhoushan Port.The channel uses the world's largest ore ship as the design ship type,and it is the first400,000DWT channel designed and put into operation in China.Restricted by the islands,reefs and port layout,the channel flow condition is complicated,and navigation and berthing conditions are bad.Because the waterway condition is one of the most complicated navigable waters in Zhoushan,the design of the channel is very difficult.In this paper,we make a comprehensive analysis of the characteristics and difficulties of the channel,reasonable ship traffic organization and navigation mode are put forward,we optimize the channel design scheme by ship simulation tests,determine the window period of navigation by theoretical calculation and real ship testing,and obtain a real-time flow observation scheme during the test run.
