BP Uses RFID Sensors to Track Pipe Corrosion
The system, provided by Permasense, enables the oil company to monitor pipe thickness at its refineries worldwide.
Based on the results of those trials, BP is now in the process of installing the system at all 11 of its refineries worldwide (located in Australia, Europe and North America), with six installed and operating to date. In the meantime, the researchers launched Permasense in 2009 to continue developing and marketing the product for use with other oil firms.
According to Collins, BP intends to install thousands of sensors over the next few years. (BP did not respond to requests for comments.) Thus far, one refinery is installing more than 1,000 sensors, while the others are starting with fewer units. Each sensor sends ultrasonic waves into a pipe wall, and measures the waves reflected back. The walls of uncorroded pipes range from 3 millimeters to 25 millimeters (0.1 inch to 1 inch) in thickness, and the system can sense a loss of as small as 0.1 millimeter (0.004 inch). Each sensor's radio chip transmits its unique ID number and the measurement data at preset intervals.
To modify the sensor unit so that it can sustain the high pipe temperatures—which can exceed 1,000 degrees Fahrenheit (538 degrees Celsius)—the sensor and RFID hardware is housed in a plastic casing and attached to the pipe wall via a set of legs, about 12 inches in length, through which the ultrasound waves are transmitted and received. The outer tips of those legs are attached to a mounting welded directly to the pipe.
In the future, Collins says, each of BP's refineries could use tens of thousands of sensors. Permasense has been marketing the system to other oil companies since the fall of 2010, and is currently in conversations with those interested in employing the technology.
