The following pipeline inspection images and videos were captured using a variety of intrinsically safe and explosion proof video pipe crawlers. Maverick deploys these long range systems into pipelines to help integrity groups, engineers, consultants and other pipeline professionals make evaluations from recorded video documentation. Sampling of material, retrieving foreign objects, and laser profiling are optional accessories for pipeline applications.
Remote Video Inspection (RVI) is the use of camera systems to image the internals of structures, equipment, and components that are otherwise inaccessible due to physical configurations, safety concerns, or other limitations. Maverick has a proven video inspection service track record including rapid response emergency services, working with our clients to plan RVI requirements for turnarounds, assisting in the development of predictive maintenance execution plans, and sourcing out or developing unique inspection technology.
This video shows a newly laid flex gas line before commissioning. The video inspection was performed to determine whether any deformation existed before key the system went online. Fifteen feet in, the video showed the circumferential deformation of the pipe at the anchor support.
INJECTION LINE COATING DEFECTS
In this video, there is evidence of a failure of the cement lining of this water/oil injection line. The coating defect exposed the carbon steel walls to possible internal corrosion. An explosion-proof pan and tilt camera was used to capture this data to pinpoint the area for repairs.
PITTING IN A SOUR GAS PIPELINE
This video inspection observed a 4" sour gas pipeline with internal corrosion at the 6 o'clock position of the pipe. Cluster deep pitting was observe and this area of the line, which was later cut out and replaced. Maverick uses a variety video pipe cameras for inspecting smaller diameter pipelines.
NATURAL GAS PIPELINE - PIG BAR DAMAGES
This video shows a large natural gas pipeline with internal damages to the main pig bars. An intrinsically safety pan, tilt & zoom camera was lowered through the riser section and remotely operated to record the problem area. The main ball valve was noted in the closed position.
6" SOUR GAS PIPELINE
This short video clip shows corrosion channeling at the 6 o'clock position of the gas pipeline. Maverick used a video pipe crawler with a pan, tilt, and zoom camera to observe and record the internal conditions of the pipeline.
GAS PIPELINE LINER DAMAGES
In this video, there is an area inside the gas pipeline where the poly liner appears to have collapsed. The pipe contained both H2S and other explosive gases, so an explosion-proof robotic crawler was used.
