Inuktun Sighting #167: Confined Space Culvert Inspection with Inuktun Versatrax™ Robotic Crawlers

This week’s #InuktunInTheWild sighting is courtesy of Greenman-Pedersen Inc. (GPI) who needed to inspect culverts too small for personnel to safely access. There are a lot of risk factors associated with culvert inspection including locations below fill embankments, confined spaces, situations where rapid or unexpected increases in flow may occur, and uncertain structural integrity. Eddyfi Technologies’ Inuktun robots have been designed specifically to see far in advance to reduce risk and eliminate the need for Confined Space Entry (CSE), operating in even the most extremely hazardous environments – just check out this example!

GPI’s Underwater Inspection Team deployed the Inuktun Versatrax 150™ Analog pipe inspection vehicle for the successful underwater remote visual inspection (RVI) of a number of small culverts. End treatment, slope protection, undermining, clogging, traffic surface treatment and condition, fill embankment fitness, and durability of culvert material and coating are all considered during culvert inspections. Operators paired with a robust inspection robot like the Inuktun Versatrax 150™ system can easily assess abrasion, coating loss, corrosion, cracks, joints, seams, shape changes and deflection, perforations, and undermining.

According to GPI’s Michael Nitchman and David Cornish, “Greenman-Pedersen Inc. has been commissioned by numerous clients to provide underwater structural inspections of bridges, canal structures, waterfront structures and water handling structures including culverts. In order to most effectively perform inspections of these structures, GPI has employed a variety of methods and techniques including the use of inspection divers, sonar and acoustic imaging, and remotely operated vehicles of various types. On numerous occasions GPI has utilized the Inuktun Versatrax crawler system to inspect interior surfaces of low clearance and/or smaller sized culverts which lack sufficient headroom for a diver-inspector to safely enter and perform inspection duties. In some cases, vertical clearance was limited to less than one foot. The Versatrax system works well for this type of application. It provides clear inspection video, has good mobility in the confined space over uneven terrain, and is very durable and stable in high flow environments.”
