The Baku-Tbilisi-Ceyhan (BTC) Consortium is responsible for the design, installation and operation of the pipeline to carry crude oil from Azerbaijan via Georgia to the Mediterranean port of Ceyhan in Turkey. The Consortium has subdivided the works into separate contracts for each country, with the Turkish sector awarded to Botas Petroleum Pipeline Company.
Botas contracted Wärtsilä to provide the pumps, drivers, site erection advisory and commissioning, for the four pump stations in Turkey. The pipeline in Turkey represents approximately 1076 km of the total 1820 km long pipeline. The pipe, with a diameter of 42 inches (1067 mm), has a maximum flow of approximately 1 million barrels per day (approximately 6700 m3/h).
The four pumping stations are at elevations of 1600 m to 2140 m. The Wärtsilä 34SG engines, fuelled by natural gas, are used as pump drivers via a step-up gearbox. There are fourteen pump sets with Wärtsilä 18V34SG engines and four pump sets with Wärtsilä 12V34SG engines. The pumps are connected in two stations in parallel and in two stations in series. The pump capacities are 1675 m3/h and 6700 m3/h with a maximum differential pressure of 86 bar.
