Permasense Limited has been exhibiting at the world’s foremost event for the development of offshore resources in the fields of drilling, exploration, production and environmental protection - the Offshore Technology Conference (OTC) in Houston, Texas
The drivers of corrosion and erosion - process conditions, crude constituents and abrasive solids - and the inhibitors to hold corrosion rates in check are familiar, but understanding the levels and rates at which damage may be occurring is an ongoing challenge. Permasense have been providing insight into the benefits of continuous monitoring for upstream applications, and demonstrating how its corrosion monitoring system works.
The permanently installed solution that Permasense provides can operate in extreme temperature environments and inaccessible locations. The system combines ultrasonic sensor technology with wireless communication to deliver data of the highest integrity to the end user.
The company showcased its new long-range corrosion monitoring system which allows retrieval of data from monitoring locations up to 40km from the gateway location. Building on the proven technology of the Permasense short-range system, the long-range system has been developed to allow for easy deployment on pipeline and feeder lines upstream and midstream. Again, the system offers an efficient and safe way to monitor the integrity of pipework enabling better informed decision making and improving operator flexibility.
Dr Peter Collins, CEO of Permasense, commented, “Continuous measurement presents a step change in the levels of corrosion rates that can be determined and the accuracy of that determination. We are pleased by the rapid acceptance of our breakthrough technologies by the industry, with more than 3,000 sensors already in operation in over 40 facilities in 11 countries.”
The system has been deployed in refineries and upstream facilities, including offshore platforms, worldwide. To date, 12 super-major and privately held oil operators have adopted the system. Proven in continuous operation for over four years in demanding environments at a number of facilities, the Permasense continuous corrosion monitoring systems can be found in the US, Canada, Germany, Australia, China and a number of other countries.
