Oil & Gas Thermal Imaging Applications

Thermal imaging is widely used in the oil and gas industry to identify potential problems that the human eye simply cannot detect. The non-invasive, non-destructive inspection method has proven to significantly increase asset safety, saving onshore and offshore oil and gas companies millions of dollars in rig and installation production downtime. Thermal imaging technology is used throughout the oil and gas industry in a diverse range of applications for both predictive maintenance and condition monitoring (CM) including:

- Sand level evaluation in tanks and vessels
- Gas leak detection
- Pipe integrity
- Corrosion Under Insulation (CUI) inspections
- Flare header line inspections
- Insulation inspections on LPG/LNG holding tanks
- Cathode protection assessments
- Optical gas imaging
- Electrical thermography
- Moisture ingress in pipe lagging

Why Use Us For Your Thermal Imaging Needs?

- Save time by using an inspection method that covers a lot of ground in a short amount of time
- Save significant time in plant or production downtime
- Save resources
- We are ITC professionally trained Thermographers with many years experience in the oil and gas industry

- We do not compromise safety!

Sand Level Vessel & Tank Inspections

Certain tanks and vessels suffer from the build-up of sand deposits which sometimes makes it challenging, not knowing when to shut the system down and open up the vessel for cleaning. Using infrared technology, our experienced thermographers can evaluate the sand deposit level quickly and easily with higher accuracy than any other non-invasive method. Trending reports from periodic inspections are then generated and tracked over time. Each of the thermographic reports supplied will include 4 of the previously imaged inspection points, allowing your process engineers to quickly understand the problem and organise sand and sediment removal in the next planned shut down window.

Benefits of Sand Level Inspections

- High thermal resolution 640x480 pixel images (1280x960px using Ultramax)
- 45 degree germanium lens used to capture a large footprint in one image
- ITC certified thermographers with real oil and gas experience
- Laser range-finder measurements used to aid in consistent and accurate thermal images
- Comprehensive reporting and trending of sand/sludge levels between inspections
- Quantitative and qualitative analysis with 48hr report turn-arounds

Oil & Gas Thermographic Surveys

As a rule of thumb, electrical and mechanical thermographic surveys are best undertaken while plant or equipment is operational at a 40% minimum load. Examples of historical thermographic surveys include:


- Live inspection detecting loose bus-bar fittings
- Identifying load imbalances, failing fuses and loose terminal block connections
- Evaluate equipment experiencing misaligned drive shaft issues
- Identification of passing valves in high pressure process pipework
- Identification of poorly fitted bolts on pipe flanges
- Monitor bearing temperature on mud pump shafts during high pressure pumping

Thermal Imaging for Corrosion Under Insulation

Corrosion Under Insulation Inspections

Corrosion Under Insulation (CUI) can be extremely hazardous in the oil and gas industry. Tanks, vessels and pipework contain highly volatile gases and liquids which if leaked could trigger a catastrophic event.

 

Utilising thermal imaging to locate potential areas of corrosion under insulation, we can bring to attention areas where CUI is likely to form. Highpoint Solutions provides world-class thermographic solutions for pipeline condition monitoring, along with detailed testing and inspections to evaluate the integrity of insulated pipelines, vessels and storage tanks.

Pipeline Applications for CUI Inspections

 Internal corrosion

 Weld-line identification
 External corrosion
 Heat affected (HAZ) corrosion
 Changes in pipe schedule
 Pipe blockages
 Wet insulation
 Determination of product level in piping
