Using Crawler Technology For Detecting Pipeline Defects

Confined space inspection is being revolutionised through the use of robotics, with equipment such as VT100MK11 Crawler offering advantages such rapid deployment, user-friendly operation and multiple configuration options.

The ability to locate and monitor pipeline defects in what are often hostile environments is crucial for both planned and emergency maintenance. Historically, such investigations have been hampered by lengthy preparation necessities and access challenges. But with the evolution of technology, such miniature pipe inspection systems are being embraced by industries such as the oil and gas, energy, nuclear, municipal and more.

Key applications of the VT10MK11 Crawler

As pipelines age it’s inevitable that defects will occur. Being able to accurately determine the integrity of such structures on a regular basis not only lessens the chance of unexpected repairs, it actively extends their longevity. This is thanks to areas of concern being proactively monitored and planned repair or replacement carried out in a timely manner.

The VT 100MK11 Crawler provides an effective method of NDT testing in the smallest of pipelines, offering a multitude of configurations that can tackle virtually any confined space application. The system can easily be primed for inspections such as:

  • Inline or small diameters
  • Parallel configuration for larger diameter pipes and ductwork
  • With magnetic attachment for inverted and vertical travel
  • Within hulls and tanks
  • Low profile requirements
  • Pre start-up inspections
  • Subsea (to 60m/200ft)

Benefits and advantages

The advanced crawler can operate in pipes as small as 100 mm/4 inches and its modular system allows for the camera to be connected directly to the tether or operated as a standalone drop camera. Other benefits include:

  • Completely portable and quick setup makes for rapid deployment – vital in any emergency situation
  • Front and rear facing cameras
  • Intuitive functions
  • User-friendly making it a quick system for operators to learn and effectively use

In addition to the high-definition remote visual inspection operation of the crawler, users also benefit from the ability to carry out ultrasonic testing with a further configuration option. These dual methods simplify the process of easily collating repeatable and meaningful data, providing essential information in the ongoing task of asset inspection.

The rugged construction of the VT100 MK11 Crawler makes it the ideal workhorse for the early discovery and monitoring of defects such as dents, pitting, weld fatigue, stress corrosion and microbial induced corrosion.
