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 and 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 repairing and inspecting above-ground storage tanks, we know that every storage tank is different and has unique factors to consider.

Tank Testing By Vertech Group

Many different variables 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 used, etc. That’s why we prepare our repair documents and procedures according to API-650 and API-653 requirements.

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

MEC FLOOR TANK SCANNING

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.

An operator in blue coveralls and a white safety helmet uses a sophisticated digital display inspection device for ultrasonic testing known as a MEC Scanner. The technician is focused on the device screen while the scanner is operating. The setting is an industrial environment with visible metal beams and structures. The scene is illuminated by artificial light sources that glow on the floor, emphasising the inspection task in a dimly lit area.
MEC™ TECHNIQUE: TANK FLOOR INSPECTION CAPABILITIES INCLUDE:
  • 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.

BENEFITS

A technician in red coveralls with reflective strips and a white hard hat operates a portable, wheeled ultrasonic testing device connected to a laptop known as an MEC Scanner. They are inspecting a large metallic surface, likely the wall of a tank or vessel, which has handwritten numbers indicating inspection areas. The environment is dimly lit, with shadows cast by the equipment and the worker, who appears focused on the inspection process, showcasing an industrial non-destructive testing (NDT) operation in progress.
  • 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.
