Drone Inspectors Take On Live Flare Stacks

19 March 2017

A pilot program underway by GE Oil & Gas is exploring the deployment of ground- and air-based robots or drones equipped with sensors to check oil refinery flare stacks while they are still active.

Data returned by drones enables operators to create a 3D model and track changes over time.

Traditionally, these types of assets are inspected only after the asset and related systems must be shut down, allowed to cool, and prepared for inspection during a downtime period often measured in weeks.

These robots can take readings and video footage of a variety of industrial assets. The data is then processed through a series of inspection algorithms and also made available to an inspector, who can choose to be on-site or seated in a monitoring room.

The data can be used to create a 3D model of the asset and track changes over time through subsequent inspections. For example, operators can determine if a piece of metal is starting to expand or buckle or if a miniscule crack is growing.

Robotic inspections can be performed more frequently since they don’t require a complete plant shutdown entirely. GE estimates drones and other robots can cut the amount of time needed to provide inspection by as much as 50%, depending on the assets being inspected.
