The Shah Deniz Gas Export Terminal Project involves development of Shah Deniz gas-condensate field in the Caspian Sea for a gas production of 5-7 billion m3/annum at the 1st stage.

It includes a drilling and production platform at sea, twin gas and condensate sub-sea pipelines, onshore gas and condensate pipelines, processing facility at onshore terminal adjacent to AIOC facilities at Sangachal. The project is linked with a main gas export pipeline to Turkey’s Natural Gas Pipeline system at Erzurum.

A sub-sea system will be added at a later stage to further exploit the potential of the eastern flank of the field.

The Onshore Terminal is located at Sangachal, where the Early Oil Production facilities were constructed by Tekfen- Azfen Alliance in 1996-97.

The works are executed under ‘Main Construction Works’ contract, which covers the following packages:
- Terminal Main Construction Works which includes all construction works required for gas and condensate processing:
  • Gas System - (reception, two process trains for treatment and conditioning of 900 mmscfd* gas, recompression and export metering).
  • Oil (condensate) System (reception, stabilization and treatment 62.000 bpd, metering and pumping).
- Onshore Pipelines between Shore and Terminal.
- Condensate, Rich MEG and Lean MEG (mono-ethyleneglycol) Storage Tanks.
- Power and utility systems.
- Buildings.

The storage and fabrication facilities, permanent buildings within terminal, tanks and pipelines were executed on EPC basis. Civil and structural steel, insulation and paint materials for main construction works were procured by Tekfen.
