TechCorr in-service tank inspection

In-Service or Out-of-Service

TechCorr provides expert API 653- and EEMUA 159-compliant inspections of above ground storage tanks both:

Our team consists of highly trained technicians, analysts, and inspectors, along with a state-of-the-art robotic inspection system.

Detailed Analyses

Following API 653 and EEMUA 159 guidelines, our inspections include detailed analyses of all aspects of the tank’s:

  • foundation
  • internal floor
  • tank shell
  • nozzles and appurtenances
  • fixed roof.

Additionally, our analysts provide calculations for the:

  • safe-fill height
  • hydrostatic test height
  • time frame for subsequent inspections.

Our Techniques

To ensure accurate and thorough data collection, our teams use a variety of inspection techniques, including:

  • visual inspections
  • B-scan ultrasonic testing
  • pit gauging
  • vacuum box testing
  • magnetic flux leakage (MFL) scanning
  • wet fluorescent magnetic particle (WFMP) testing
  • diesel testing
  • automated corrosion mapping
  • 3D digital reconstruction inspection and integrity analysis.
TechCorr in-service tank inspection

The key to TechCorr’s in-service inspections is our robotic inspection system, a remotely controlled hydraulic robot specifically designed to inspect in-service tank floor bottoms. System features include:

  • an array of 8 ultrasonic transducers that collects thickness measurements every .1” (2.54 mm)
  • a sludge removal vacuum system that cleans the tank floor as the robot inspects
  • a video system mounted on the robot that allows for a visual inspection of the internal roof
  • a compact design so that the system needs only a 20” (508 mm) portal for deployment.
