This follows full completion of construction and commissioning of the pump station. The first stage of linefill and operational testing is in anticipation of the celebration of first oil into the pipeline on 25 May. 10 million barrels of crude oil are required to fill the 1770-km long pipeline, running from the Sangachal terminal near Baku via Georgia to the Ceyhan terminal on the Mediterranean coast of Turkey. The oil comes from the Azeri-Chirag-Gunashli (ACG) field in the Azerbaijan sector of the Caspian Sea. The staged filling of the pipeline along its entire route could take over six months, and the loading of the first tanker at Ceyhan is expected in the fourth quarter of this year. The BTC pipeline will allow 1 million brl/d of oil to be exported safely and responsibly from the Caspian without increasing tanker traffic through the Bosporous Straits. The operators of the line, together with the operators of the South Caucasus pipeline (SCP), being built to carry Shah Deniz gas from the Caspian to Georgia and Turkey, have spent around $30 million on community and environmental investment in Azerbaijan, Georgia, and Turkey during the construction phase. A regional sustainable development programme is being developed which will build upon the best practice of existing community investment programmes, as well as addressing some of the regional and national challenges posed by the development of large-scale oil and gas businesses. The BTC shareholders are BP (30.1%), SOCAR (25.00%), Unocal (8.90%), Statoil (8.71%), TPAO (6.53%), Eni (5.00%), Total (5.00%), Itochu (3.40%), Inpex (2.50%), ConocoPhillips (2.50%), and Amerada Hess (2.36%).
