ClampOn AS is a Bergen-based company specializing in non-invasive ultrasonic intelligent subsea sensors, and is the largest supplier of ultrasonic sensors forthe oil and gas industry. 85% of the company´s products are exported out of Norway, to markets including the UK, the US, Brazil and Australia. ClampOn´s sensors provide additional information to help manage the flow of oil and gas ? for example, sand/particle monitoring, pig detec- tion, and leak monitoring. As the company´s name sug-gests, ClampOn´s sensor products are non intrusive ? they clamp on? to existing subsea systems. They can also be moved around without the risk of leakage. They are particularly effective subsea where they can be used to monitor for leaks or problems in the flow line on an ongo- ing basis. Most recently, the company has introduced a non-invasive solution to the problem of corrosion and erosion in subsea pipelines ? a key challenge to prolong- ing the life of mature fields. ClampOn´s Corrosion- Erosion Monitoring System uses acoustic transducers to monitor wall thickness and send information to the sur-face about the condition of a section of pipe. Between two and eight transducers are mounted on the pipe surface, and connected to a ClampOn control unit. Ultrasonic sig- nals are sent continuously through the pipe material, received by a sensor and analyzed to give a picture of the condition and thickness of the pipe.
