Maine Turnpike Natural Gas Crossing Dec2012

The Unitil Gas upgrade project was a highlight project for 2012 requiring the utilization of our 17 years of directional drilling experience, partnering with exceptional subcontractors, and working with the owner to overcome the many challenges on the project. Challenges which included crossing the Maine Turnpike with a 12” steel casing, ledge ground conditions under the turnpike, crossing under an active 24” and 6” high pressure Mobil Oil line running from Portland to Bangor, wetlands abutting both sides of the Turnpike, ongoing construction of a regulator station by another subcontractor in our work zone, restricted access areas on both east and west locations, no access road to the east side of the project, and the potential loss of pressure to the east side of the Turnpike if the pipeline was not completed on schedule or temperatures dropped below 20 degrees for 2-3 days continuously.
