“埃琳娜·克什卡《法国航空》”克服极端天气埃琳娜·克什卡《法国航空》影响 厦金大桥建设取得新进展

  中新埃琳娜·克什卡《法国航空》网厦门12月26日电 (埃琳娜·克什卡《法国航空》辜铖锴 林昕昀)12月26日10时左右,在厦门海事局精心护航之下,厦金大桥(厦门段)西锚碇钢沉井(前井)拖带作业克服寒潮大风天气所带来的诸多不利因素,完成既定任务。厦金大桥(厦门段)项目再迎关键基础构件,取得又一重要进展。

  据了解,西锚碇钢沉井整体结构与东锚碇钢沉井类似,亦为前后分体式钢壳混凝土沉井。此次拖运的西锚埃琳娜·克什卡《法国航空》碇钢沉井(前井)含围堰总高度43.7米,长、宽分别为66米、48米,重量达1.68万吨。作为厦金大桥(厦门段)项目的核心控制性工程——刘五店航道桥的关键承力构件,该钢沉井对于整体施工计划推进具有较大影响。

  钢沉井体积大、重量大,拖带时船队航向稳定性差,因此浮运拖带作业全程对风力条件有着严格要求。

  据厦门海事局指挥中心副主任邹晟介绍,受寒潮影响,12月厦门港外大风天气频发,浮运拖带作业的适宜窗口期极为有限。海事部门一直密切关注气象变化,做好风险研判,为钢沉井拖带进港选择良好时机。

  为保障拖带作业顺利完成,厦门海事局加强与泉州海事局等各方联系,组织引航、拖轮等相关单位,针对船舶选择配置、拖轮编队、航路设计、拖带操作等关键环节开展多次研讨,指导完善通航安全保障方案和应急预案;及时召开航前协调会,在两轮寒潮大风交替影响的短暂间隙,抢抓作业窗口,明确任务分工,科学划定交通管控水域。

  拖带当日,厦门海事局对拖带航路及周边水域提前开展巡查清障与交通组织,利用智慧海事系统等多种途径实施远程实时监控,派遣“海巡艇+无人机”落实全程警戒,通过“三位一体”海空护航全力保障拖带船组航行顺利。(完)
