  • Comparison of core sampling and visual inspection for assessment of concrete sewer pipe condition

    Sewer systems are costly to construct and even more costly to replace, requiring proper asset management. Sewer asset management relies to a large extent on available information. In sewer systems where pipe corrosion is the dominant failure mechanism, visual inspection by closed circuit television (CCTV) and core sampling are among the methods mostly applied to assess sewer pipe condition. This ...

  • Down Hole Motor Inspection

    There is an old familiar proverb about how “for want of a nail, a kingdom was lost”. The moral of this story is that the failure or lack of even a small item can, in certain circumstances, have a very big impact. A drilling operation uses lots of very expensive equipment and supplies, and requires the expertise of several very qualified workers. Ask anyone in the industry, and they ...

  • Underwater Bridge Inspections – Drones Conducting Remote Evaluations

    Deep Trekker Remotely Operated Vehicles (ROV), or underwater drones, are establishing themselves as the ideal tool for underwater bridge inspections. It goes without saying that the structural integrity of a bridge is extremely important; after all, you’re only either walking, driving, or riding a train across it. With the public safety in mind and to continue the flow of traffic, these ...

  • A Monster Pipe Demands Monster-Size Inspection Approach

    From a purely visual perspective, some pipeline inspections are more awe-inspiring than others. This is especially true when everyone involved describes the pipe diameter as “monster-size,” clocking in at 210 inches in diameter. A challenge of this magnitude requires fresh thinking from an inspection approach, especially when the subject pipe is so critical to the lifeblood of the ...

  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • What`s in the numbers? a review and analysis of more than 400 miles of force main inspection and condition assessment data

    Abstract Comprehensive condition assessment of wastewater force mains provides significant challenges to owners/operators of collection systems as the ability to shut down or expose the pipeline for a thorough inspection is often impractical due to operational and/or financial considerations. Traditional gravity sewer inspection techniques (i.e. visual-based technologies) do not always ...
