Working with a pipeline operator to inspect historically un-piggable pipelines. We have had some great success with the new launchers & receivers, which were only 4.5ft long, and allowed us access to some very tight dig sites. The Pioneer pigs were blown through the line in a controlled manner with an average speed of 2 m/s. The Pioneer pigs did a good job of cleaning the lines while inspecting for internal defects at the same time. A great start in making un-piggable pipelines piggable.
