The Shvabe Holding of the Rostec State Corporation has started serial production of a fiber-optic transmission and conversion system for optical signals (FOCS) to control the subsea complex of offshore oil and gas production. The technological solution significantly surpasses all existing equipment in information transfer speed, including foreign ones.
The system provides the transmission of commands and data from the control sensors of the subsea oil production complex at a distance of up to 85 km and a depth of up to 500 meters. The developed algorithms for signal processing and conversion allow connecting up to 48 end devices to the FPIC.
“Rostec's development opens up new opportunities in the management of offshore oil and gas production. Unlike the existing samples, which transmit signals over an electric cable, the operation of the FPIC is based on the use of a fiber-optic system. Thanks to this, the speed of information transfer is several times higher, and in the future we will be able to increase this indicator tenfold. Our specialists took into account all the features of the equipment functioning at great depths - the guaranteed service life of the system is at least 30 years, ”said Oleg Evtushenko, executive director of Rostec.
Engineers have developed a system of highly reliable digital fiber-optic modules that transmit an optical signal at a wavelength of 1.55 microns at a speed of up to 1 Mbps. The project as part of the Shvabe holding is being implemented by the Polyus Research Institute named after M.F. Stelmakh.
“Within the framework of the project, prototypes of an underwater optical splitter were also developed and manufactured. It divides the optical line into four channels and allows you to connect a larger number of devices, ”said Sergei Popov, Deputy General Director for R&D at Shvabe, Head of the Priority Technology Direction for Optoelectronic and Photonics Technologies.
Rostec optoelectronic enterprises are implementing a number of projects for the oil industry. Among the core developments of the Research Institute "Polyus" is a system for increasing the accuracy of inspection of main oil, gas and other pipelines. The development allows you to determine the location of damage and reduce the percentage of oil and gas leaks, thereby minimizing harm to the environment.
