Abstract

The invention relates to a method for introducing a pig-like tool into an operating pipeline, such as a fluid pipe. According to the invention the pipeline is drilled during operation and the tool is injected into the pipeline through the drilled hole. During a corresponding tool removal from the pipeline a method is provided for prereconnaissance for the determination of a degree of contamination, cleaning, surveying, inspecting, repairing, etc. of pipelines by means of a corresponding, pig-like tool. The invention also relates to a device and a tool permitting the performance of the inventive method. Thus, otherwise unpiggable pipelines can be worked in a cost-efficient manner.
