What is pipe and sewer inspections?

When it comes to pipes and sewer systems that are always underwater divers are often required as draining isn't an option. This results in a substantial amount of set up time and the need for extra safety equipment for the divers, not to mention placing the divers in a dangerous environment. Subsea ROVs are the perfect solution to this removing the need for extra equipment and improving the safety of inspection operations.

How do pipe and sewer inspections work?

  1. A subsea ROV is lowered into the pipe or sewer system. The operator then turns it on and views the camera from the display.
  2. The subsea ROV is then piloted, inspecting every centimetre of the pipe or sewer system, taking photos, and recording footage to be inspected afterwards.
  3. The subsea ROV is then taken out, washed off, and packed away for next time.

Benefits of using subsea ROVs

  • Divers are no longer required to enter dangerous areas and confined spaces.
  • Areas that aren't accessible to humans can now be inspected with ease, ensuring a more thorough inspection is done.
  • Multiple subsea ROVs can be deployed at the same time to increase efficiency.
  • As subsea ROVs are tethered they can operate for hours at a time thanks to the tether, compared to divers that rely on a source of air.
