摘　　要：近年来,国内海上风电场的开发建设选址逐渐向离岸更远、水深更大的方向发展,其基础中的钢管桩设计参数也在向着超长、超大、超重及多样化的方向发展。为适应在近海超水深条件下打设超长超重钢管桩的要求,从节约成本方面考虑,在不改变现有装备水平条件下,公司对自有的108 m超大型打桩船“铁建桩01”等进行了局部二次创新设计与改造,包括双抱桩器系统设计与改造、替打与桩帽套筒设计与改造、起锤机构多用途改造等,使“铁建桩01”打桩船的施工工艺得到了相应优化,能适应更多种复杂作业环境的应用范围,提升了设备性能,更安全高效地完成施工任务,曾创造了同类型打桩船安全施打φ2.0 m-125 m-177 t超长超重钢管桩的沉桩纪录。In recent years,the development and construction site selection of domestic offshore wind farms has gradually developed towards the direction of farther offshore and deeper water depth,and the design parameters of steel pipe piles in their foundation are also developing towards the direction of over length,over size,overweight,and diversification.In order to meet the requirements of driving ultra long and overweight steel pipe piles under offshore ultra deep water conditions,considering cost savings,and without changing the existing equipment level,the company has carried out local secondary innovative design and transformation of its own 108 m ultra large pile driving vessel“Tiejian Pile 01”,including the design and transformation of the double pile holding device system,the design and transformation of the replacement driving and pile cap sleeve,and the multi-purpose transformation of the hammer lifting mechanism.The construction process of the“Tiejian Pile 01”pile driving vessel has been optimized accordingly,which can adapt to a wider range of complex operating environments,improve equipment performance,and complete construction tasks more safely and efficiently.It has created the same type of pile driving vessel for safe driving record of pile sinking forφ2.0 m-125 m-177 t ultra long and overweight steel pipe piles.
