Duratec was engaged by Yara Pilbara to undertake an inspection of the carbon dioxide vent silencer at their ammonia processing plant by utilising a remotely piloted aircraft system (Drone).
The client had found that pieces of perforated metal plate were found in various locations of the of the plant (ISBL) area. The purpose of the inspection was to determine the extent of damage sustained to the silencer.
Given the greatly elevated position of the vent silencer, a drone inspection was deemed to be the best option to provide invaluable information on the damage without the requirement to take the plant off line or to perform high risk inspection works.
As a result of the inspection, the client was able to use the footage to formulate a temporary method for containing the damage prior to fabrication and installation of a replacement silencer.
Following this Duratec returned to site to confirm the adequacy and function of the damage containment solution.
- High powered zoom lens of onboard payload was able to keep a safe distance from the online plant whilst gaining required footage of the sustained damage.
- High definition imagery and video of the deterioration and a summary of the findings were presented in a report to the client.
- Drone inspections are advantageous in that photographic evidence of the damage can obtained whilst maintaining plant production and mitigating high risk work such as scaffold installation, working from elevated work platforms and inspections via rope access.
