7日，全球最大专用140米级打桩船“一航津桩”在江苏启东交付。该船由中交一航局投资研发，上海振华重工建造，是全球桩架最高、吊桩能力最大、施打桩长最长、抗风浪能力最强的专用打桩船，我国水工建设领域再添一座“大国重器”。

作为海上施工利器，该船桩架高142米、最大作业桩重达700吨、最大作业桩长达118米、最大作业桩径达6米，是国内首艘具备全回转舵桨和侧推辅助定位、DP0动力定位系统的超大型打桩船，能够克服外海施工海况恶劣、涌浪和长周期波对船舶施工的影响，可满足长航调遣，在施工水域内实现自航移泊驻位，极大降低船舶调遣和作业时对辅助船舶的使用需求，节能降耗的同时有效提高生产效率。

交付后，该船将主要用于大型桩基施工、群桩式基础、风电导管架桩、风电单桩等施工，将进一步适应国家海洋经济战略与海上风电能源开发，为开拓海上风电施工领域提供重要的装备保障。

The world's first 140-meter piling vesl was officially delivered in east China's Jiangsu Province on Friday, beefing up China's infrastructure construction.

The record-breaking vesl, called Yihangjinzhuang, is equipped with the world's highest pile frame of 142 meters, the largest hoisting capacity of 700 tonnes, the longest piling length of over 118 meters under water, as well as strong wind and wave resistance capabilities.

The vesl will be ud to build up large scale pile foundation for ports, cross-a bridges and offshore wind farms.

It also adopts veral tech innovations including a power system for a quick launch, an electrical engine for flexible movement and a lf-developed digital management system.

The ship was developed by the No. 1 Harbor Engineering Company Ltd. under the China Communications Construction Corp. and built by Shanghai Zhenhua Heavy Industries Co., Ltd.
