小型耙吸挖泥船在黄骅港泊位清淤施工中的应用

Use of Smaller Trailing Suction Hopper Dredger in Berths′ Dredging for Huanghua Port

黄骅港处于淤泥粉砂质海岸,年回淤量大,采用非自航式挖泥船进行泊位清淤,施工船舶落实困难,费用高。采用小型耙吸挖泥船进行泊位清淤,有效解决了黄骅港泊位清淤的困难,而且比采用绞吸挖泥船节省费用约50%以上,同时实现了和生产船舶零干扰。探索出了淤泥粉砂质海岸泊位清淤最经济、便捷、无干扰的施工方法。

Huanghua Port lies in the silt-sandy coast and has large siltation. Using tabor hopper dredger to carry out dredging in the berths is difficult and the dredging cost is high. Using smaller trailing suction hopper dredger to carry out dredging in the berths has effectively solved the difficulties in Huanghua berths＇ dredging and the cost was cut by about more than 50% when comparing with the using of cutter suction dredgers, resulting in zero-disturbance to the normal navigation operation of other vessels. It explores the most economical, convenient and no interferential construction technology for berths＇ dredging in siltsandy coasts.
