ALS elevates Visual Inspection outcomes by combining our qualified experts with industry leading inspection aids.
Visual inspection is a seasoned and basic inspection method, yet it remains a critical step in inspecting the condition of any asset, from equipment to structures.
The visual inspection process involves the observation of an asset’s condition, with an inspector accessing for visual signs of corrosion, cracks, physical damage, significant flaws or the misalignment of parts. This inspection can combine the use of raw human senses, such as sight, touch and hearing, with rope access solutions, Remote Digital Visual Inspection (RDVI) equipment and other non-specialised inspection equipment. The visual inspection process frequently precedes other non-destructive testing.
Visual inspection can be carried out on an array of assets including equipment and structures, which include:
- Pressure vessels
Advantages of Visual Inspection
In the hands of appropriately skilled inspectors, effective visual inspection can reveal important information and a greater understanding of:
- The presence of significant flaws, including weld defects, cracking and corrosion.
- The compliance of welds and other components with specifications.
- Evidence indicating the reasons why unexpected events such as failures have occurred.
- The condition of the asset and an assessment, where appropriate, of its functionality and remaining life.
The ALS Approach
At ALS, visual inspection is performed by our qualified materials scientists, tank inspectors (API), welding inspectors, and pressure vessel and classified plant inspectors (AICIP and API) and engineers. Our scientists, inspectors and engineers are highly experienced and are equipped with effective visual inspection aids, tools and access solutions to ensure the value of all visual inspections are maximised.
ALS inspection teams utilise RDVI equipment which includes:
- High resolution borescopes.
- Telescopic access poles with high-resolution video cameras attached.
- Crawlers and rovers with the capacity to traverse most terrains.
- Remote Piloted Aircraft/ Drones/ UAV driven by CASA licensed, qualified inspection staff.
- Submersibles or marinized cameras and rovers.
