考虑客货船“双峰”会遇的内河受限水域船舶横越方法

    Ship crossing operation methods in restricted inland waters considering "double peaks" encounter of passenger and cargo ships

    • 摘要: 旅游业复苏使兼具旅游与航运功能的受限水域航道客货船舶交叉混行局面愈发频繁,传统客运船舶逐排连续横越航道造成水域通航风险激增,已无法适应复杂通航环境。考虑客运船发船高峰期和货运船乘潮期“双峰”叠加的复杂局面,在传统横越方法的基础上提出逐排跟船横越方法。基于交通冲突技术和动态船舶领域理论,分别构建大角度和小角度转向逐排跟船横越模型。利用黄浦江繁忙水域掉头区的船舶自动识别系统(AIS)数据,对客运船横越方法进行仿真验证。研究结果表明:当船舶间保持最紧迫距离时,客运船采用大角度和小角度转向逐排跟船横越方法可改善采用传统方法无法安全开航的情况;在不同船舶交通流密度下,相比大角度转向逐排跟船横越方法,采取小角度转向逐排跟船横越方法最大可提升客运船50%的横越效率。所提出的逐排跟船横越方法在保证通航安全的前提下可大幅提升客货船交叉通航效率,为海事管理部门协同提升内河受限水域航道通行效率和安全提供方法参考。

       

      Abstract: The continuous increase in crisscross navigation between passenger and cargo ships poses a significant threat to navigation safety in restricted inland waters. Traditional row-by-row crossing operation methods are inadequate for ships navigating such complex environments,leading to a surge in navigational risks. This study proposes an enhanced row-byrow following ship crossing operation method,building upon traditional approaches to address the dual peak periods of passenger ship departures and tidal effects. Based on traffic conflict technology and dynamic ship domain theory,largeangle and small-angle row-by-row following ship crossing models were developed. The advantages of the proposed methods are validated using actual Automatic Identification System( AIS) data collected from the turnaround area of the busy Huangpu River. Results indicate that both the large-angle and small-angle row-by-row crossing methods effectively mitigate the safety limitations of traditional methods. Furthermore,the small-angle row-by-row crossing method improves passenger ship crossing efficiency by up to 50% compared to the large-angle method. The proposed row-by-row following vessel crossing operation method demonstrates significant potential for enhancing navigation efficiency and safety in restricted inland waterways,particularly in congested turnaround areas.
