When it comes to pipeline safety and structural integrity assessments over great lengths, there are many constraints that must be overcome to collect the essential data required to make confident decisions in effective risk management programs.
Whether it is the extensive pipework that cities rely on for its municipal water, the vehicle for transporting oil and gas over long distances, or the hydroelectric penstock responsible for keeping the lights on at night, the sound operation of this infrastructure is simply not optional.
Advances in technology continue to offer an increasingly clearer picture of real-time conditions for a more proactive approach to fitness-for-service assessments.
Moreover, a symbiotic approach to multi-technologies now enables asset owners with operating and cost-efficiencies like never seen before.
The challenge for Eddyfi Technologies – gain a better understanding of internal pipeline conditions referencing tangible data results collected over long distances.
The immediate challenge that an internal pipeline inspection overcomes is the ability to bypass flanges, supports, insulation, and coatings that prevent a long-distance external survey.
In addition, many pipes are often buried which means that the asset owner would need to undergo costly excavation. On the contrary, elevated pipelines introduce the additional expense of erecting scaffolding or requiring rope access which further invites safety risks.
The ability to obtain more than just visual data for pipelines under inspection is becoming more and more crucial.
Collecting additional ultrasonics or current testing data has become a common request for these inspections using robotic crawlers.
Unfortunately, the majority of solutions available cannot incorporate these technologies or can only integrate over short distances. As such, solutions have historically been limited to custom solutions with low volume, long turnaround times, high maintenance costs, and even higher prices.
The solution – commercially available pipe inspection robot enables integration of complementary technologies for comprehensive dataset.
The VersaTrax™ represents a family of pipe inspection robotic crawlers that can endure hazardous environments and traverse long distances, the standard VersaTrax 320 able to penetrate up to one km (3,300 ft) from a single access point. Custom solutions help clients like Interactive Pipe Inspection truly go the distance.
When their Lake St. Louis project required locating and inspecting 11,280 m (37,000 ft) of sewer lines under the lake with only one onshore manhole access, they turned to Eddyfi Technologies Center of Excellence for Robotics (formerly Inuktun).
With a requirement to deliver a solution for pulling 1,200 m (4,000 ft) of cable to inspect 200 mm (8 inch) pipes, the client confirmed that the long-distance robot was successful. Another case study featuring inspection of a fully submerged water intake tunnel is available.
