Hennigan Engineering performs video inspection services through our “Tunnel Vision Inspection Services” division, providing comprehensive infrastructure video investigation and low to high pressure hydrojet cleaning services. Our equipment includes the industry’s latest high tech equipment. Each Tunnel Vision vehicle is outfitted with every type of camera required for video inspection of pipes from 1 1/2-inch up to 120-inches in diameter.
In addition to this, we have been called upon by our clients to design, build and operate specialized, one-of-a-kind pieces of video equipment to inspect infrastructure situations that are unusually complicated and require custom equipment. Tunnel Vision has designed equipment that performs video inspection of tunnels up to 20 feet in diameter and over 2 miles long.Tunnel Vision also performs Foreign Material Removal (FME or FME Removal) from piping and equipment where ready access to the material is not available.Through the use of cameras and robotic retrieval equipment, Tunnel Vision is able to retrieve the smallest of items from your system, preventing these items from reaching components that can damage a small system or in some cases shut an entire plant down for extended periods.
