Internal Inspection of the Pipelines
The intelligent Pipeline Inspection Gauge (PIG) makes it way from the PIG trap at the start of the pipelines in Portovaya, Russia, through the pipeline, and is recovered in Lubmin, Germany at the end of the pipelines. The internal inspection tool is designed to detect any sign of corrosion, the internal dimensions of the pipeline, its precise position, size and coordinates, and the exact run of the pipelines curves. This video tells the story of its journey through the Nord Stream Pipelines.
