Aerial Robotic Systems

A Novel Approach to Safe Coating Inspection at Heights

From JPCL, July 2018

By Jamie Branch, Apellix

Aerial robotic technology offers a novel approach to obtaining coating inspection data more efficiently, while reducing an inspector’s occupational exposure to dangerous heights. This article addresses the benefits and limitations of utilizing aerial robotic systems as a viable means of coating inspection....

Neat, but the usefulness of a drone for DFT readings is limited - mostly I owuld see using this for a condition survey performed not during an active project. Typically in an active project the inspector doesn't "wait for scaffolding to be built" - because the blasters and painters were already working from the scaffolding. If there is access to blast and paint, there should be access to inspect.

Agreed with Tom, the most challenge job is blasting and paint application job. Anyhow, it's a small step moving forward of big data.

There are pros and cons to the idea of using drones for inspection. Anyhow any current technology that can give added value to the industry is welcome.

Great idea for ships and tanks, but not so much for your typical multigirder bridge with the limited space between girders. And yes, if there's blasting, there's access to an inspector as well. Where I can see this being useful is where you have large truss or cable stay bridge or similar and you need an impromptu inspection for a sudden emergency condition that comes up, and the heights are large yet flight space/access is large. Or if the owner agency wants to do a survey of paint condition when contemplating paint maintenance work or total blast job. Designers rarely get access to a bridge prior to planning such work since traffic lane closures and/or scaffolding is impossible.

The above technology is fantastic for existing assets where a condition survey is required for maintenance repair works. It is cost effective and a safer approach.

Would be useful for a final inspection after a painting project is over - aid in spotting any rigging mount points or damage which didn't get proper touchup/repair during derigging.
