摘要： Remote-controlled joining system for subsea pipelines for joining two smooth pipeline ends (pipe ends) that are arranged facing in line a distance apart, with means arranged to move at least one of the pipeline ends sideways and in the longitudinal direction. The joining system is distinguished by comprising: a pipe sleeve having internal seals against each pipeline surface, for insertion of pipe ends to facing position within the seals, and a welding clamp with integrated welding tool for remotely welding of a first end of the pipe sleeve to the first pipeline and a second end of the pipe sleeve to the second pipeline, the welding clamp can be remotely fastened sealingly around the pipe ends and the sleeve and is equipped with means for establishing and maintaining a welding atmosphere in a volume delimited by the seals of the clamp and the seals of the sleeve.
