Part of the proceedings of
In April 2010, the state-owned Russian OJSC Transneft operating the world largest (50,000 kilometers) oil pipeline system announced the creation of the OMEGA Company to install the OMEGA developed System of Monitoring of Extended Objects (SMEO) based on Fiber Optic Distributed Sensor System (FODSS) on all newly build pipelines. In February 2011 the OMEGA SMEO was for the first time presented in the United States on the Pipeline Pigging and Integrity Management exhibition and conference in Houston, Texas. The SMEO based on temperature and acoustic field monitoring has been developed for nearly a decade by Russian scientists and technologists employed now by OMEGA. The System provides high-precision detection of location and nature of acoustic vibrations, spatial displacements and temperature characteristics of extended facilities such as pipelines, oil wells, railways, highways, bridges and power lines. The extended object is monitored through the whole length of optic fiber used for the System`s sensor and not requiring electric power along the line in real time mode. In comparison to similar systems the OMEGA SMEO shows high accuracy (± 5 m) both of event detection on extended object and sensor displacement (20 to 30 mm on 6 meter length in any direction). OMEGA SMEO options available now comprise: a) The Monitoring the vibro-acoustic field of the extended facilities. The OMEGA SMEO monitors already a series of Transneft pipelines. In August 2010 the installation of the OMEGA system on the East Siberian Pacific Ocean (ESPO) Pipeline System began. b) Monitoring of the temperature field of pipelines provides integrated control over the production and transportation of raw hydrocarbons from the well to the shipment terminal. The OMEGA system is efficiently employed by the OJSC Tatneft, Russia`s 5th rated oil Company, in heavy oil production and steam injection into the well. c) Extended object Strain Monitoring. At the trials in December 2010 the newly developed OMEGA Strains Monitoring Systems of Extended Objects (SMSEO) registered the 20-30 mm bending deformation of a 6 meter long 530 mm pipe. The test results offer the prospect of implementation of the OMEGA SMSEO for instant registration of soil and pipelines sections displacement. The presentation will present the long term experience utilizing distributed fiber optical sensing technology within the Russian pipeline market and how this technology is implemented within newly build pipeline projects.
