论船舶主动避让

很多船舶不会或不愿主动避让,延误了避让时机,从而迫使其他船舶被动避让,容易引发船舶事故。船舶在避让行动中应提高主动性,采取主动避让行动,才能有效地防止和减少船舶事故。     

探析船舶操纵要素在避让中的应用实践

船舶航行过程中可能会出现碰撞风险,为了确保航行的安全性,需要及时开展避让操纵,保证船舶的安全。通过应用船舶操纵要素,可以让船舶在遭遇风险时完成合理的避让动作,并且快速完成避让。本文分析了船舶航行的原则,分析船舶避让的主要措施,最后针对如何使用操纵要素进行避让展开研究和分析,探讨不同情况下对操纵要素的应用。帮助船舶操纵人员更有效地进行船舶操纵,实现船舶航行过程中的避让,保证航行安全。     

基于改进人工势场法的船舶自动避碰研究

为解决传统人工势场法在船舶自动避碰中无法判断避让责任和紧迫局面的问题,创新性地将船舶会遇态势及危险度评价指标引人人工势场中,通过船舶之间相对方位来判断船舶的避让责任并限定避让措施,通过实时计算船舶碰撞危险度,设定相应阈值来界定是否产生紧迫局面,指导船舶采取进一步避让措施.通过对船舶对遇、交叉相遇和追越3种典型局面的仿真实验表明,本文所设计的势场能够较为清晰地判断避让责任和紧迫局面,所规划的船舶避让措施更加符合国际海上避碰规则的要求.     

长江口及长江口航道的船舶操纵与避碰

长江口及长江口航道是船舶航行的危险及复杂区域,影响船舶操纵与避让的因素有航道自然环境和人为环境因素、人员对船舶操纵性能的掌握因素、航道管理因素等。船舶在此航行时的避碰措施包括真正做到正规瞭望、严格按照航道规则航行、良好船艺、做好应急准备等,船舶在避碰中要保持安全会遇距离,及早采取避让行动,正确掌握转向避让和变速避让方法,并查核避让效果。     

喀麦隆杜阿拉航道浅区航行和施工时船舶的操纵与避让

针对疏浚作业船舶在喀麦隆杜阿拉航道浅区航行和施工过程中避让进出港船舶、渔船、渔具等较为困难的现状,依据国际海上避碰规则相关条款,分析疏浚船与进出港船舶、捕鱼船在不同情况下的避让关系,总结疏浚船舶在该航道浅区航行和施工时所需采取的特殊避让和操纵措施,为在该航道进行疏浚作业的船舶以及进出杜阿拉港的船舶提供切实可行的避让和操纵参考。     

考虑惯性延迟的船舶避让时机决策

在避让过程中，船舶的运动惯性延迟对避让效果有着重要的、不可忽略的影响。此文对已有船舶操纵避让时机决策模型进行改进，实现了考虑惯性延迟的船舶避让时机决策模型，提出了计算惯性延迟的方法。     

限制水域的船舶避让责任与避碰分析

限制水域是船舶会遇率较高的水域,也是事故多发水域。在对限制水域船舶避让的法律条款适用问题和碰撞事故原因分析的基础上,提出限制水域船舶会遇构成追越、对遇和交叉等态势下的避让责任的划分,特别讨论了限制水域端部的会遇船舶的避让责任问题。最后,对限制水域船舶避让行动提出了戒备、航行与避让、声号信号与通信、航行值班、操纵与应急操作等方面的要求。     

水上飞机避让责任相关规则修订与完善

分析水上飞机在水上航行时在航空器飞行规则和船舶水上避碰规则中的避让责任,指出在部分会遇态势中,水上飞机与船舶在不同规则中的避让责任存在差异,提出统一按船舶避让责任的划分原则,修订与完善不同规则中水上飞机在水面时避让责任相关条款的建议。     

船舶避让行动浅析

从建立船舶智能避碰系统所需要的角度出发，对船舶避碰过程中的会遇态势、避让责任、避让时机和避让行动等问题进行了分析和归类。     

能见度变化与船舶适用的行动规则

能见度变化与船舶所适用的行动规则及避让责任紧密相关,正确认识和理解能见度变化时的规则直接影响船舶驾驶员避让行动。结合自身工作实践和对《1972年国际海上避碰规则》相关条款的理解,探讨能见度变化时船舶应该如何理解适用的规则从而采取合适的避让行动,提出气象条件从互见变为能见度不良时和从能见度不良变为互见中时船舶应采取的避让行动,希望引起大家对相关问题的关注,进一步保障船舶航行安全。
