I have been very happy with the quality and response time that Master Locators has provided me on my projects. They’re very professional and have great customer service.
ArcelorMittal is one of the world’s largest steel and mining companies. The company called upon Master Locators to help with one of their projects along the Brandywine River. We provided our CCTV pipe inspection services to inspect a tunnel and show any issues in correlation with the horizontal location of pipe from above.
How We Did It
The tunnel was approximately 1,300 feet long and 8 feet wide with two access points. The walls were about three feet high, and we were concerned about the inspection of the arched brick, stone or cement roof. We needed access from both ends, but the river side proved more difficult to deploy our robotic crawler. However, our service technicians was able to equip the robotic crawler with a camera to visually inspect the pipe. We started from the inlet side and traversed the camera as far as it could go unobstructed. Then, we redeployed the crawler from the river side and sent it to the end point of the first deployment. From there, we were able to provide the client with a mark out and VPI report.
