TesTex provide a very comprehensive range of techniques & services for the inspection of above ground or below ground storage tanks. We have numerous technicians qualified to EEMUA 159 and have a wealth of experience gained from thousands of tank inspections in Europe and around the world.
The inspections can be conducted either in-service or out of service and can be from a simple ultrasonic thickness survey to a thorough inspection of the tank floor.
The results are presented in a detailed inspection report, and our inspections can include:
- Floor scans using Low Frequency Electromagnetic Technique (LFET) scanners and hand scanners to detect possible underside corrosion. Ability to scan through coatings and tightly bonded scale. The system is lightweight, battery operated, and portable.
- Shell visual and or ultrasonic thickness inspections via remote crawler or rope access techniques.
- Foundation settlement assessments to detect various forms of tank foundation movement.
- Weld inspection via magnetic particle, electromagnetic techniques, liquid penetrant, UT weld inspection and vacuum testing techniques.
- Visual inspection of the tank bund wall and bund area.
- Tank inspection & repair methodology in accordance with the requirements of EEMUA 159 or API 653.
- RBI (Risk Based Inspection) & site audits for determining inspection intervals & inspection workscopes.
- Inspection Management Software.
