Innovative Robotic Solution to Inspect Gas Storage Laterals
Bi-directional, MFL-based crawler solution to tackle challenges in storage laterals
Operators have to contend with many obstacles in order to obtain high-resolution data for their pipelines. The inspection of gas storage laterals is no exception. Though they vary in complexity, with each lateral containing its own unique characteristics, the following obstacles were consistent in each gas lateral presented in this challenge:
- No launchers and no receivers
- Single access point
- 10" lines connect to a 20" trunk line
- Limited flow conditions available
