Safety
Eliminates confined space entry and the requirement for Emergency Response Team or Tank Sentry
-
Project efficiencies
x1 UAV team (Pilot), X2 days inspection vs X2 inspections / RA team, x1 Tank Sentry, ERT Team, 6-8 days inspection.
Scope of Work
General Visual Inspection (GVI) and Close Visual Inspection (CVI) of internal crude oil storage tank within onshore oil and gas terminal. The purpose of the inspection is to ascertain the condition of the internal structure of the tank to aide decommissioning planning and enactment.
Solution
Air Control Entech deployed an ACE-A-E2 internal inspection UAV to conduct the inspection without the need for man entry. By flying from outside the tank, the team were able to eliminate man entry whilst producing valuable inspection data of the tank internals.
Full high-definition videography and photography data was captured and compiled into a report for the operator.
Results & Benefits
- Tanks emptied and isolations in place for minimal time.
- No confined space entry eliminating the need for x2 man entry team, Tank Sentry and Emergency Response Team.
- Greater visibility and enhanced maintenance planning potential for the client through provision of robust evidence on the physical state of internal tank structure and supports, i.e inner supports.
- Eliminated the requirement for multi-skilled teams reducing the risk and human factors, creating a safer and more efficient inspection.
- Project delivered on time with no disruption to ongoing plant activities.
