Baku - Supsa Pipeline Project covers the construction of 20” x 444 km FBE (Fusion Bonded Epoxy) coated new crude oil pipeline between Caspian Sea and Azerbaijan - Georgia border to be used to export the Azerbaijan crude oil to the Black Sea Coast, to Supsa.

The system, with a capacity of 115.000 bpd, is the main route of Azerbaijan, exporting Chiraq field crude oil through Georgia.

The project, first planned as a rehabilitation scheme, was later turned into a completely new lay system.

The project scope covered 335 canal, 40 stream, 51 minor water, 15 river, 6 railway, 32 bored road and 87 open-cut road crossings. Open-cut method was applied to cross a 487 m wide river with 2,5 m depth.

31 manual, 3 check valves, 607 test posts, 16 ground-beds, 16 transformer rectifier units were installed along the Azerbaijan portion of the pipeline.

During the construction, work force peaked at 805. Though, at its peak, the welding production rate reached 3 km level, relevant repair rate never exceeded 3%.

The project also achieved considerable success on HSE aspects, by being awarded for “3 million man-hours without a lost time incident / LTI”.

The project was implemented according to an “Alliance” agreement signed between Tekfen and its sister company Azfen (a J.V. between Tekfen and State Oil Company of Azerbaijan SOCAR); responsibility was equally shared in accordance with an organization plan.

The works from the Georgian border to the city of Gence was overtaken by Tekfen while Gence-Sangachal (tie-in) section was successfully accomplished by Azfen.
