Gas Leakage Find and Fix Utilizing Optical Gas Imaging & Leak Repair
TEAM deployed a work party consisting of optical gas imaging and leak repair technicians to deliver a safe and efficient solution to the user’s gas leakage risk. The project included:
- System walk-down
- Optical gas imaging (OGI) survey identifying leakage of invisible gasses
- Quantifying leakage severity using methane detector
- Production of survey results video & written report
- Leak repair to defective areas
- Follow-up methane detector survey to confirm zero leakage
The project was executed safely and successfully with all leaks being arrested. A follow-up survey physically verified the project’s cost savings and safety improvements.
What is Optical Gas Imaging?
Optical gas imaging (OGI) cameras can detect methane, sulfur hexafluoride, and hundreds of other industrial gases quickly, accurately, and safely - without shutting down systems. With OGI cameras, TEAM can scan broad sections of equipment rapidly and survey areas that are hard to reach with traditional contact measurement tools. OGI cameras can also detect leaks from a safe distance, displaying these invisible gases as clouds of smoke.
How are leaks quantified?
When leaks are identified using the OGI camera, a TEAM technician (where possible) takes a direct measurement of the leak concentration (in PPM) at the point of leakage. This provides a figure against which to prioritize and measure the effectiveness of repair efforts.
What is On-Stream Leak Repair? On-Stream leak repair technology allows leaks to be sealed while equipment is in-service. This eliminates asset downtime and restores pressure integrity. Leaks can be sealed on a wide range of pressurized system components such as flanges, valve stems, piping, vessels and tanks.
TEAM has long been recognized as a world leader in emission control services (ECS) and leak repair. Combining these technologies allows owners/operators to benefit from significant efficiency gains through:
- One contractor, two man crew – find & fix
- Arresting flammable & toxic releases – improving plant safety, reducing operating risk
- Detecting and arresting greenhouse gas releases
- Zero asset down-time – detection and repair carried on with equipment in-service
- Tangible cost savings – reducing the cost of gas emissions
