摘要
针对南海深水油气田开发的需要,以"海洋石油201"为依托,研究了海底管线铺设焊接工艺与设备。海管铺设焊接主作业线由5个焊接工作站和1个AUT/返修站组成,每个焊接工作站配备2套相同的轨道式自动焊接系统,采用GMAW自动焊接工艺,通过双车双炬、窄间隙坡口和背部铜衬垫内对口器等有效的技术手段,保证了海管优质高效焊接。自动焊接系统的焊接小车外形尺寸小、重量轻,特别适合于海管铺设工程应用,控制系统采用CANOpen现场总线和网络技术,不仅增加了系统柔性和可靠性,而且实现了现场焊接设备的远程监督。
In order to explore deep water oil and gas fields in south China sea area, a welding procedure and equipment was developed applied in sub-sea pipeline laying. The major pipeline laying line contains 5 welding stations and 1 AUT and repair station, and each welding station has 2 same orbital automatic welding system, which has several features such as GMAW process, two welding carriages with dual torch, narrow gap and internal line up clamp fitted with copper backing rings. The welding carriage is specially designed for offshore application, so it is compact and lightweight. The control system of the automatic welding station is constructed on the CANOpen bus and Ethernet technologies, so the flexibility and reliability of the system are greatly improved, and the pipeline welding process also can be monitored remotely.
