摘　　要：宁波舟山港核心港区进港航道已出现阶段性饱和。在核心港区进行超大型船舶码头建设,须细致分析航道通过能力承载力和泊位本质安全水平。以在金塘港区新建3个30万吨级原油码头为例,运用潮汐窗口理论分析了宁波舟山港核心港区超大型船舶的航道通过能力,运用船舶模拟操纵技术分析了超大型码头的船舶净间距要求。研究结果表明:1)宁波舟山港核心港区航道通过能力可以承载新增3个30万吨级原油码头带来的通航压力。2)建议相邻大型码头船舶净间距不小于1倍船长。The approach channel in the core area of Ningbo-Zhoushan Port has been saturated in stages. For the construction of terminals for very large vessels in the core port area, it is necessary to carefully analyze the carrying capacity of the channel and the inherent safety level of the berths. Taking the construction of three new terminals for the 300,000 DWT very large crude carrier(VLCC)in the Jintang port area as an example, this paper analyzes the carrying capacity of the channel for VLCCs in the core area of Ningbo-Zhoushan Port using the theory of tidal windows. Moreover, it explores the requirements for the net spacing between VLCC berths using ship maneuvering simulation. The study draws the following conclusions: 1)The channel carrying capacity of Ningbo-Zhoushan Port could bear the traffic pressure brought by the addition of three 300,000 DWT VLCC terminals. 2)It is recommended that the net spacing between adjacent large berths should not be less than a ship’s length.
