| Résumé : |
Traditional coating inspection techniques require extensive manual testing by the inspector, often at vertical heights that must be accessed by equipment such as scaffolding, lifts and ladders. Aerial robotic technology offers a novel approach to obtaining big data more efficiently, while reducing an inspector's occupational exposure to dangerous heights. This article addresses the benefits, as well as limitations, of utilizing aerial robotic systems as a viable means of coating inspection.
Dry film thickness (DFT) is an integral component in determining the quality of a coating job. Strcutures with large surface areas will require enormous quantities of data to ensure that a coating is in compliance with the applicable standards and specifications. For example, if 300,000 m² of flat surface called for coating inspection by DFT, a minimum of 45,000 gauge readings would be required for compliance with SSPC-PA 2. To obtain these measurements, the inspector must manually touch the probe to the material being measured. Current handheld electronic Type 2 DFT equipment is conveniently designed to be lightweight and portable; however, it requires the inspector to physically access the testing sites, which are frequently located at dangerous heights. Scaffolding, scissor lifts, fall protection and other access equipment are utilized to reach test sites, which are expensive and present fall hazards to personnel accessing them. The Bureau of Labors Statistics reports that 849 workers lost their lives in 2016 from falling while on the job across all industries. The United States Occupational Safety and Health Administration (OSHA) established a hierarchy of hazard protection that specifies that engineering fall hazards out and away from the workplace is the most effective strategy for keeping workers safe. An alternative to performing measurements manually at the test site is to utilize an aerial robotic system to perform the measurements with the worker safely on the ground. This method satisfies OSHA's hierarchy of fall protection by engineering the fall hazard away by removing the necessity of the worker to access heights. |
