“The project was an excellent example of working in concert through every aspect of the planning stage, with everyone invested in a successful outcome…”
The first time new parties come together to work on a pipeline inspection project, they face a lot of pressure to perform. The team must instill trust and understand each other to ensure the project goes off without a hitch. In this instance, that’s what happened when Pure Technologies (Pure) and its long-time partner WRc came together with Irish Water and Cork County Council (CCC) to assess and address the condition of a critical water main in the City of Cork, Ireland.
As this was the first collaborative project among the four groups, it was also a test of the planning expertise, engineering skills and technology advances for Pure Technologies and WRc to impress upon Irish Water and Cork County Council. In the end, the inspection was successful, lessons were learned, and a positive new relationship was forged.
Project Begins With Six Months of Planning
After six months of planning, in March 2017, Irish Water and its consultant WRc engaged Pure Technologies to conduct a non-destructive evaluation of approximately six (6) kms (3.7 miles) of 1500mm (60-inch) and 1200mm (48-inch) prestressed concrete cylinder pipe (PCCP) sections in the water main between Chetwynd reservoir and Carrs Hill, using the SmartBall® pipeline inspection platform.
SmartBall tool provides acoustic signature related to leaks and gas pockets
For the Inniscarra Water Main inspection, Pure Technologies deployed its proprietary SmartBall technology, a multi-sensor tool used to detect and locate the acoustic signature related to leaks and gas pockets in pressurized pipelines. The tool has the ability to inspect long distances in a single run, and while the SmartBall is deployed, the pipeline remains in service, limiting disruption to customers.
Unlike traditional listening tools like correlators, which have limited success on large diameter pipes, the free-flowing SmartBall technology provides a high degree of accuracy, because as the device travels along the pipeline, it continuously records the acoustic environment within the line. All data is stored onboard the device and later evaluated to determine the presence and location of any leaks or pockets of trapped gas.
