HOUSTON -- Baker Hughes Pipeline Management Group (PMG) has introduced a new method to assess the effectiveness of a pipeline's cathodic protection system from inside the pipe. It is called the CPCM In-line Inspection (ILI) Service.
"Conventional technology requires teams of technicians to walk the actual pipeline route to acquire measurements at pre-defined intervals," says Steve Schroder, Baker Hughes PMG GM. "The CPCM In-line Inspection Service utilizes a smart pig traveling through the line, performing high-resolution cathodic protection measurements of the entire pipeline, minimizing valuable time and resource requirements.
There are no gaps in the data stream due to rough terrain, lakes or streams, city streets and other inaccessible areas. The quality of the data is maintained regardless of right-of-way conditions. Obviously, the system is also ideal for assessing offshore pipelines."
