Source: www.gulfoilandgas.com 12/10/2012, Location: Asia

Gazprom Transgaz Surgut has completed a comprehensive upgrade of compressor workshops at the Yarkovo and Samsonovsky Line Pipe Operation Centers.

The upgrade included the replacement of outdated 11.9 MW gas compressor units (GCU) by the 16 MW CGUs. The company also provided compressor stations with new service lines including power, water, heat and gas supply lines, oil lines, systems for removal and purification of sewage, oil containing and domestic wastewaters, auxiliary equipment, GCU piping, junction points. It also established a cutting-edge electronic system for equipment control and management.

Construction and assembling operations were performed in seven stages, with one or two units decommissioned at a time, which made it possible to deliver the planned gas volumes avoiding compressor workshops shutdowns at stations and gas transmission reduction.

The implemented engineering solutions improve the gas transmission system reliability and security.

Gazprom Transgaz Surgut is a wholly-owned subsidiary of Gazprom and one of the largest gas transmission companies of Western Siberia. The company’s major facilities include 14 line pipe operation centers, 18 compressor stations and 37 compressor workshops containing 266 gas compressor units.

CS-6 of the Samsonovsky Line Pipe Operation Center maintains the Urengoy – Chelyabinsk gas trunkline from 876th to 979th kilometers, gas laterals stretching to the Khanty-Mansiysk city and the Salym settlement as well as 8 gas distribution stations. Compressor workshop No.1 of CS-6 was commissioned in 1978.

CS-10 of the Yarkovo Line Pipe Operation Center secures gas transmission from 1,262nd to 1,373rd kilometers of the Urengoy – Surgut – Chelyabinsk section. The CS was established in 1978.

By the beginning of upgrade, the Koberra-182 GCU was highly overaged, the efficiency of the supercharger and the power turbine decreased, while the operating costs and capital overhaul expenses increased. Meanwhile, some changes were made in the comprehensive industrial safety regulation and Gazprom’s requirements concerning the necessity to improve operational properties as well as reliability and security parameters.
