Inspectahire offers atmospheric tank inspection, building on many years of experience of remote vehicle inspections in hazardous / EX environments, vessels and tanks.
The company aims to first understand the customer’s requirements, comply with established inspection standards (API 653 and EEMUA 159) and consider technology to further enhance inspections and exceed both inspection standards.
Key to these challenges is a substantial investment in personnel and equipment, including the application of new technology alongside extensive training and continuous review of complementary activities.
The two main types of atmospheric storage tanks encountered are floating roof tanks and fixed-roof tanks. Each type requires a range of inspection techniques.
Tank inspection techniques
- MPI – magnetic particle inspection, used for the inspection of the shell to bottom weld and seam welds
- Dye Penetrate – used for the inspection of the shell to bottom weld and seam welds
- Magnetic Flux Leakage – used to assess the condition of the tank floor and locate defects on underside of floor plates
- Pulsed Eddy Current – used to assess the condition of the annular ring
- Vacuum Box – used to test the integrity of the shell / bottom weld and majority of seam welds
- CCTV and Pneumatic Mast – used for the inspection of drains, pipes, and areas where access is most difficult negating the use of scaffolding where access is at height
- Ultrasonic and Remote Ultrasonic – used to measure the wall thickness of shell strakes and tank roof plates by following vertical scan lines on the tank shell from the ground.
- Visual – overall inspection of foundations, holding bolts
