Ultrasonic testing
Use sound to investigate material thickness and internal indications.
Storage tanks
A structured view of the whole tank.
Inspection areas to consider
- Shell courses and accessible plate surfaces
- Nozzle connections and external welds
- Roof details and external condition
This example covers external inspection of a metallic tank. Internal entry and floor inspection require a separately agreed plan.
Define the question.
Then the examination.
A storage tank assessment begins with a defined scope and access plan. Organise observations by component so that the record remains useful long after the site visit.
Useful information to prepare
- Tank drawings, material and operating history
- Components included and excluded from the scope
- Cleaning, access and isolation arrangements
Methods to explore
Explore the purpose and limits of each method. Material and site conditions determine the final inspection approach.

Magnetic particle testing
Reveal surface and near-surface indications in ferromagnetic components.
Visual inspection
Build a clear record of the condition visible at accessible surfaces.
