Our tank testing team conducting Magnetic Flux Leakage (MFL) and API 653 storage tank inspections in QLD

Tank Testing Services

Vertech understands that bulk storage tanks are assets of both strategic and operational importance for companies across a large range of industry sectors. Our specialised range of storage tank inspection services assists our customers in maintaining their tank inspection activities, maintenance and repair schedules to ensure maximum availability while complying with Australian Standards and EPA requirements.

Our clients benefit from our team of experienced API-653 tank inspectors and engineers who can evaluate the inspection data, perform remnant life calculations, design weld repairs and prepare weld procedures.

API 653 Aboveground Storage Tank Inspectors must have a broad knowledge base and receive periodic training for proper storage tank testing procedures.

From our years of experience in the repair and inspection of above-ground storage tanks, we know that every storage tank is different and have their own unique factors to consider.

Tank Testing By Vertech Group

There are many different variables that come into play when designing a repair procedure such as the specific gravity of the stored product, the age of the storage tank, the construction material that was used etc. and that’s why we prepare our repair documents and procedures according to API-650 & API-653 requirements.

We also tailor our repair procedures specifically to suit your needs based on your industry’s operational requirements.

Innospection’s storage tank inspection package with the next generation MEC™ technique and integrity management as per EEMUA 159/API 653 standards is a cost effective solution with the benefit of a reliable and thorough inspection for peace of mind.

MEC™ (Magnetic Eddy Current) is the next generation and further development of the industry-proven fast corrosion screening SLOFEC™ technique.

  • High sensitivity in detecting corrosion, pitting and local defects in tanks with plate thickness up to 30mm & coating thickness up to 10mm
  • Ability to inspect lined and unlined carbon steel and stainless steel tanks.
  • Direct sizing of defects during scanning without the need for Ultrasonic verification.
  • Ability to inspect the tank annular plates.
  • High inspection speed of approx. 25m/min.
  • Ability to inspect overlapped welds in lined tanks.
  • Minimal surface preparation prior to inspection.
  • Separate reporting for topside and underside defects.


  • High sensitivity and reliability in detecting topside and underside defects from including small and shallow pitting caused by bacterial corrosion (from Ø >3mm and 10% wall loss).
  • No coating removal or shot blasting of tank floor is required prior to inspection, resulting in a faster and more economical operation as well as a shorter time for the tank being out of service.
  • Analysis of defect severity in terms of volume and wall loss.
  • Low cleaning requirement prior to inspection
  • Direct sizing of defects during scanning without the need for Ultrasonic verification with accuracy of +/- 10% for onsite reporting and +/- 5% for special offline analysis.
  • Differentiation of defects from non-defects such as inclusions and laminations.
  • Enables fast and efficient scanning and C-scan mapping of large areas.
