7日，全球最大專用140米級打樁船“一航津樁”在江蘇啟東交付。該船由中交一航局投資研發，上海振華重工建造，是全球樁架最高、吊樁能力最大、施打樁長最長、抗風浪能力最強的專用打樁船，我國水工建設領域再添一座“大國重器”。

作為海上施工利器，該船樁架高142米、最大作業樁重達700噸、最大作業樁長達118米、最大作業樁徑達6米，是國內首艘具備全回轉舵槳和側推輔助定位、DP0動力定位系統的超大型打樁船，能夠克服外海施工海況惡劣、涌浪和長周期波對船舶施工的影響，可滿足長航調遣，在施工水域內實現自航移泊駐位，極大降低船舶調遣和作業時對輔助船舶的使用需求，節能降耗的同時有效提高生產效率。

交付后，該船將主要用于大型樁基施工、群樁式基礎、風電導管架樁、風電單樁等施工，將進一步適應國家海洋經濟戰略與海上風電能源開發，為開拓海上風電施工領域提供重要的裝備保障。

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.
