Their goal was to improve availability and reliability for uninterrupted gas delivery to consumers.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">In addition, they wanted to eliminate process oil in the bearings to reduce required maintenance and potential fire hazards throughout the 900 kilometres of pipeline and 55 billion cubic meters of gas.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">Gazprom began operation of compressors with active magnetic bearing (AMB) systems in the early 2000s. Since then, they had worked with one local supplier and had little success.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">With low reliability and the low quality of the local supplier’s equipment, customers weren’t receiving the gas in appropriate volumes, and with cold temperatures, repairs often took longer.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">In late 2008, Gazprom partnered with Mitsubishi Heavy Industries (MHI) and Waukesha Magnetic Bearings (WMB) to develop a more reliable system. MHI provided a 16MW gas compressor and WMB supplied the AMB system for the compressor.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">In total, four gas compressor units with WMB systems were installed at the Elizavetinskaya-1 site and were successfully commissioned in early 2012. All components were certified according to Russian standards (GOST).</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">Gazprom results showed immediate improvement over the other system in operation. After 10,000 hours of operation, the availability exceeded 95%. This increased reliability means continuous gas delivery and energy security to consumers in a sustained manner.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">The AMB system from WMB increased the mean time between repair from three months to more than five years, reducing maintenance costs and total cost of ownership. It also provided simpler integration with the compressor station due to the digital output/input from the digital control cabinet, versus previous experience with analogue cabinets.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">Additional benefits included time savings with an easier commissioning and tuning process, remote monitoring and adjustment capabilities, higher processing performance that allows for more complex algorithms that provide higher dynamic efficiency, improved usability and ergonomics, and noise immunity.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">The success of the first installation of four sets led Gazprom to approve the Waukesha Magnetic Bearings AMB system application for future projects.</span> </p> <p style="margin:0px 0px 10px;padding:0px;border:0px currentColor;border-image:none;color:#111111;line-height:20.8px;font-family:inherit;font-size:16px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"> <span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;line-height:1.6em;font-family:inherit;font-size:inherit;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;"><span style="color:#000000;font-family:Arial;font-size:12px;">Mikhail Ponomarev is with</span><span style="color:#000000;font-family:Arial;font-size:12px;">&nbsp;</span></span><a style="margin:0px;padding:0px;outline:0px;border:0px currentColor;border-image:none;color:#1D4B7B;line-height:1.6em;font-family:inherit;font-size:inherit;font-style:inherit;font-variant:inherit;font-weight:inherit;text-decoration:none;vertical-align:baseline;font-stretch:inherit;" href="http://www.waukbearing.com/en/magnetic-bearing-systems/system-details" target="_blank"><strong style="margin:0px;padding:0px;border:0px currentColor;border-image:none;line-height:inherit;font-family:inherit;font-size:inherit;font-style:inherit;font-variant:inherit;font-weight:bold;vertical-align:baseline;font-stretch:inherit;"><span style="color:#000000;font-family:Arial;font-size:12px;">Waukesha Magnetic Bearings</span></strong></a><span style="margin:0px;padding:0px;border:0px currentColor;border-image:none;color:#000000;line-height:1.6em;font-family:Arial;font-size:12px;font-style:inherit;font-variant:inherit;font-weight:inherit;vertical-align:baseline;font-stretch:inherit;">.</span> </p> </div> </div> </div> <br class="Apple-interchange-newline" />
