As several significant events over the past few years have shown, the cost of an undetected pipeline leak can be catastrophic. Shutting down a pipeline, even for a relatively short time span, has a significant impact on revenue, while the costs of clean-up and litigation are skyrocketing.
Many companies use smart pigs to determine potential leaks, but there is a much simpler and more reliable strategy available.
Smart pigging, like hydro-testing and all other pipeline maintenance tools, has many limitations. The accuracy and reliability of smart pigs are both greatly affected by operational conditions, and even when those conditions are perfect, smart pigs only detect areas of leak potential. They can easily miss points in the pipe that are actually leaking while recording false positives that require a company to make inaccurate or unnecessary digs.
External pipeline leak detection equipment typically detects one or two materials that might be leaking from a pipeline.
Pipeline leak detection equipment often needs to be transported making it more difficult to use in rugged, mountainous terrain.
Most of the smart pig companies are from Texas so you often have to pay to have the unit shipped to your site.
Pipeline leak detection equipment is very expensive.
The bottom line: DDSI can save you a tremendous amount of time and money compared to using leak-detection equipment.
