CCTV Pipeline Inspection System

CCTV Pipeline Inspection Camera

We recently acquired a portable closed circuit television (CCTV) pipeline inspection system, which we can use to perform a thorough examination of your pipes, from 12” up to 72”. With this system, we can inspect lengths of pipe up to approximately 800’ in length.

CCTV inspection is one of the most effective methods to determine a pipe’s defects, the likelihood of failure, and its rehabilitation needs. CCTV takes the guesswork out of pipe inspections, enabling quick, accurate, and cost-effective examination of drains, sewers, and other pipelines, without causing any damage to the infrastructure.

Five Reasons to Use CCTV:

  • Efficient:  Cameras use real-time footage.
  • Accurate:  CCTV inspections give us the ability to accurately view, record, and analyze any problem with multiple perspectives.
  • Flexible and Versatile:  The camera can examine pipes of varying widths and lengths with its 360° panning and 135° tilting capabilities.
  • Cost Effective:  As a method of “non-destructive testing,” the operator can conduct an investigation fairly quickly while the pipes remain intact.
  • Safe:  By eliminating the need for human occupancy in a confined space, we are eliminating safety risks.

Drainage is one of the most important components to keep a railroad operational. It can also be one of the most overlooked and neglected parts of a railroad. The Federal Railroad Administration (FRA) mandates the inspection of all culverts in a railroad drainage system — however, these are often in hard-to-access locations, and at times they can be long and too small to access, preventing us from inspecting the structure just by observing the ends of the pipe.

Many times, the structures have been extended or modified over the years since their installation, and the pipe may change directions or grades, which prevents us from getting a clear visual. Many of these drainage structures date back to when the railroad itself was originally built, and their construction records have been lost. In these situations, it can be difficult to know for certain how they were built, or how many times they were modified.

The benefit of using a CCTV system mounted on a crawler unit is that it allows video documentation of the entire pipe length. In addition, you are provided with a formal report that meets utility industry standards, using the Pipeline Assessment and Certification Program (PACP) reporting and software. By using CCTV inspections and PACP standards in our inspections, we can compare different pipes and culverts to prioritize maintenance.

Because the inspection data is all created with the same benchmark, the decision-making process is made simpler and easier, making room to focus on the most urgent parts of your infrastructure when it comes to year-to-year project planning and budgeting. Using PACP standards and certified operators, we can also remove inspector subjectivity from the inspections. This yields data that is more uniform and shareable with others, to be analyzed on an equal footing.

PACP also allows comparison of a current inspection with a previous inspection. This allows us to see how changes in the pipe or culvert are occurring over time, and helps us plan when replacement or rehabilitation of the structure may be required for long-term budgeting purposes.

In time, personnel, equipment, technology, and procedures can all change. These changes have a profound effect on the inspection data, and on how one understands the condition of its assets. PACP can bring continuity to how information on your pipes and culverts is documented and interpreted.
