Marine Technology Reporter Blogs - leak-detection

As more and more equipment is placed on the seafloor, especially in deep waters but also in shallow waters, concerns grow over potential hydrocarbon leaks from trees, manifolds, pumps, pipelines, flowlines, risers and valves. It’s no small challenge to have a reliable subsea leak detection system that can monitor the large array of subsea systems used in modern deepwater fields and on top of that there is the need to monitor the working condition of all this equipment and others, such as ESP’s and other pumps, which are rotating equipment. Acoustic emissions are the stress waves produced by the sudden internal stress redistribution of materials caused by changes in the internal structure.

During the recent Rio O&G 2014 Expo and Conference a range of new products for the O&G industry were launched. The size of the event, with over 1,000 companies present and tens of thousands of daily visitors made it a great medium for showing new products to the market. GE had its large booth constantly full and was probably the company, which had the largest number of new products on display. Naxys joined GE in September 2012 as a world-class sensors developer for the subsea sector. With its headquarter in Bergen, Norway, Naxys develops and supplies leak detection and condition monitoring sensors based on proprietary, passive acoustic hydrophone technology.
