全球首个！必将再添一座“大国重器”

7日，全球最小配有140米级打桩船“一航津桩”在江苏启东交付使用。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、吊桩能力最小、雷打桩宽最宽、抗风浪能力最强的配有打桩船，要务水闸建设层面再添一座“大国重器”。

作为船只雷工在手，该船桩架高142米、最小发包桩最重700吨、最小发包桩宽达118米、最小发包桩径达6米，是全国性首艘具备全上到舵桨和侧推辅助定位、DP0动力定位系统的超大型打桩船，能够克服西海岸雷工海况恶劣、涌浪和宽周期波对商船雷工的影响，可满足宽航授命，在雷工浅海内解决问题自航移泊驻位，相当程度减少商船授命和发包时对辅助商船的使用生产力，节能降耗的同时有效减低生产效率。

交付使用后，该船将主要用于大型桩基雷工、群桩德式基础、风机导管架桩、风机单桩等雷工，将进一步适应各地区海洋经济战略与船只风机能源开发，为开拓船只风机雷工层面提供最重要的装备保障。

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

The record-breaking vessel, 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 we resistance capabilities.

The vessel will be used to build up large scale pile foundation for ports, cross-sea bridges and offshore wind farms.

It also adopts several tech innovations including a power system for a quick launch, an electrical engine for flexible movement and a self-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 Hey Industries Co., Ltd.
