Hi-tech safety

Inspection Tools
Pipeline operators use hi-tech devices called "smart pigs" to scan their pipelines for potential issues. Smart pigs travel inside the pipe scanning the pipe walls using technology like an MRI or ultrasound at the doctor's office. Smart pigs use magnetic resonance to look for corrosion and ultrasound to look for signs of cracking. An operator can customize its inspection of a pipeline by selecting tools designed to identify or confirm the absence of specific issues.
Data Analysis
Digital data from a smart pig inspection is analyzed with the aid of sophisticated modeling and imagery software. Even though most pipelines are buried underground, inspection results can provide views of both the pipe wall exterior and peer inside the steel itself. Like a doctor's exam, data from an inspection can confirm a clean bill of health, diagnose a potential problem or help prescribe maintenance to correct the issue.
