黄骅港煤炭港区超限船舶对航道通航效率的影响

Influence of over-limit ships on navigation efficiency of channel in Huanghua coal port area

针对黄骅港煤炭港区人工长航道通过能力有限的现状,研究LNG船舶等超限船舶严格的通航规则对煤炭船舶通航效率产生的影响。基于通航管理现状,采用多智能体仿真建模方法,构建煤炭港区船舶-航道-泊位作业仿真模型,通过6组工况分析定量评价超限船舶进出港产生的通航效率影响。结果表明,年到港超限船舶达到70艘次时,单船造成的延误船舶超过2.4艘次,延误时间超过1.1h,且超限船舶管制规则越严格,产生的影响越大。建议煤炭港区严格控制超限船舶数量,保证煤炭船舶通过能力。

In view of the limited through capacity of the artificial long channel in Huanghua coal port area,we study the influence of strict navigation rules for over-limit ships such as LNG ships on navigation efficiency of coal ships.According to the current situation of navigation management,we adopt the multi-agent simulation modeling method to establish a simulation model of ship-channel-berth operation in coal port area,and quantitatively evaluate the influence of the navigation efficiency caused by the over-limit ships entering and leaving the port through the analysis of six working conditions.The results show that when the number of over-limit ships reaches 70 per year,coal ships delay caused by the single over-limit ship will be more than 2.4,and the average delay time is more than 1.1 h.Moreover,the stricter the regulation rules of over-limit ships are,the greater the impact is.It is suggested that the coal port area should strictly regulate the number of over-limit ships to ensure the passing capacity of coal ships.
