Plant profitability, fuel flexibility and low environmental impact are of key importance for LNG plant operators. This paper describes recent developments of Siemens stationary gas turbines to meet these criteria. Key contributors to plant profitability are gas turbine reliability and availability. Current Reliability Factors for Siemens medium-sized gas turbines are above 99%. Optimized reliability is achieved by a systematic approach during product development and product improvements through systematic feedback of fleet experience. Optimized availability is achieved through an efficient service organization in combination with fast core-engine exchange.

This paper describes the supply of four SGT-400 Gas Turbine generating packages rated at 12.9MWe each, to Uralkali JSC of Russia for installation at two potassium mines in Berezniki City. The SGT-400 engines are the key components for two cogeneration plants which are located in one of the main industrial centers of the Ural region. Each cogeneration plant will comprise two generating sets in order to provide efficient and reliable production of power and steam for use in the mines and for the manufacturing process. The paper describes the advantages of the technology and the details of the specific application.
