A new breed of pipeline “pig” has arrived in the United States.
“Pigging” to clean pipelines is an accepted procedure used by utility pipeline owners.

A recent project to install more than 6,200 feet of electrical transmission lines in Orange Beach, AL, included multiple challenges, including two intersecting horizontal directional drilling (HDD) pilot holes beneath Wolf Bay inter-coastal waterway channel to complete a single crossing.
