SPE “Mashproekt” Gas Turbine Engines for Gas Pumping Sets

Abstract

The paper describes the experience gained in designing, developing and operation of gas turbine engines for gas pumping units on the marine gas turbine engine’s base. More than 800 Mashproekt gas turbines of various power output have been in service in gas pumping application since 1980. This paper shows the SPE Mashproekt designing and developing approach for gas turbines to be installed in gas pumping units along with their full-scale testing in the test bed of close gas loop type equipped with gas compressor and gas coolers to simulate operation of the gas pumping unit in the real gas pipeline conditions. The gas turbines for gas pumping application on the 2.5 MW, 6 MW, 10 MW, 16 MW and 25 MW engines base were developed in the period of 1990–1995 for replacement of the existing old gas turbine line-up and installation in the new gas pumping units at the compressor stations in Russia and Ukraine. We are replacing engines with Mashproekt gas turbines at the following gas pumping units: Russian GTN-25, Ukrainian GPA-6.3, GPA-16 and “Coberra-182” (Great Britain) gas pumping units. The comparison of the technical characteristics of these replacements is given in the paper. Technical data on 2.5–25 MW Mashproekt gas turbines for gas pumping units is also presented in this paper.
