In April 2009 at Sivas compressor station (Turkey) commissioning and 72-hour tests of gas turbines designed by Aviadvigatel OJSC and mass produced by Perm Engine Company were completed. It is the first project of gas compressor equipment sales to a foreign customer completed by the Perm engine companies.
Sivas compressor station (Turkey)In 2006 Perm Engine Company received an order for supply of three GTU-16PE gas turbines for Sivas compressor station. The gas turbines are part of GPA-16P/76-1,6M1 gas compressor packages produced by Sumskoe NPO OJSC named after M.V. Frunze. For foreign customers convenience the entire operational documentation is executed in the English language.
GTU-16PE features a set of process equipment including PS-90GP-2 gas turbine on underbase frame that is the core element of the pakage and furnished by transmission, inlet section, units, piping and electric system communications, control cabinets mounted on the wall of the noise and heat isolation enclosure.
The heart of the gas turbine is PS-90GP-2 engine equipped with hydropneumatic compressor vanes and valves control system. The engine rated power is 16 MW, turbine inlet temperature is 1416 K, compressor pressure ratio is 19.61; efficiency is 37%. The engine is started by StV-5G-01 pneumatic detander starter.
The gas turbine is equipped with MSKU-5000 automatic control system for gas compressor packages. GTU-16PE design features are explosion-proof design of electrical equipment and wiring, application of Woodward fuel metering and Honeywell pressure sensors. It is worth mentioning that for the first time in PS-90GP-2 engine design they used a combustor case with hatches, through which it is possible to replace combustor cans on the installed engine.
In May 2007 Perm specialists completed installation of gas turbines and prepared them for commissioning. This year during the commissioning of GPA-TS-16P/76-1,6M1 gas compressor packages equipped with GTU-16PE gas turbines, Perm equipment again confirmed its declared high performance. It is especially important because for the first time gas compressor equipment designed by Aviadvigatel OJSC will operate in highlands conditions as the station is located at about 1500 meters above the sea level.
Sivas compressor station belongs to the Botash pipeline which is a Turkish pipeline monopolist company. Through the 1491 km long pipeline gas is transported from Dogubayazit town on the Iranian border to Ankara and then to the countries of Western Europe.
Participation of Perm engine companies in the Turkish project is very important for further expansion of the geographic area of gas compressor equipment designed by Aviadvgatel OJSC and produced by Perm Engine Company operation outside of Russia.
Moreover, the diversification of sales and operating companies is indicative of Perm gas turbine equipment importance both in the domestic and world market of gas turbine products.
At the crossing of the world civilizations
Sivas compressor station got its name from the town situated in the central part of Anatolia and founded in the 1st century B.C.
The town name Sivas goes back to the Hittite word Sibasyp which meant the urban settlement on Topraktepe hill nearly 2 thousand years B.C. Later on the same place appeared a town, which belonged under different names (Kabiri, Diospasis, Sebastea) to the lands of Phrygians, Assyrians, Romans and Byzantians, the Seljuks, the Mongols and Turks. In the Middle Ages Sivas was a famous centre of trade, situated on the crossroads of caravan tracks to Persia and Bagdad, a well-known Silk way.
As a modern tourist centre Sivas is famous for its ancient madrasahs (there are 5 of them) and a mosque. Historical memorials keep traces of the past magnificence, ornate stone and brick decorations, black and blue glazed tiles used for finishing.
Sivas has become known all over the world thanks to thermal mineral springs located near the town. The unique method of treating serious skin diseases with the help of sacred fish is used in Sivas Kangal health-centre. And, of course, modern Sivas means famous Turkish hospitality, sun and pure mountain air.
