Dowletabad 15–GPCP, Gas infrastructure Project for Turkmengas, Turkmenistan. A US$200 million LSTK contract.

In order to transport gas from the rich natural gas field of Dovletabad, south Turkmenistan, and then sell it to external markets, Turkmenistan needed proper infrastructure and compression systems.

The  natural gas infrastructure project, known as Turkmengas Dowletabad 15–GPCP, was design by Bateman Litwin to answer the need.
The project included Gas Preparation and Compression Plant (GPCP) - Sovetabad 15 with a capacity 20 billion Nm3/y and dew point control.

Site facilities control the gas flow from 95 wells. The gas is cleaned from H2S and dried in four 500m3/hr primary processing plants, a utilities center and a sulfur recovery plant. The gas is then sent some 2000 kilometers to Russia and to Western Europe through transnational pipeline system.

The contract model for the project was Lump-Sum Turnkey. Moreover, Bateman Litwin has facilitated a financing package of US$ 200 million.

The project also includes advanced telemecanique and telemetering System (SCADA) along the SAZ-4 pipeline (750 km). This system gives Turkmengas the ability to monitor the 750Km pipeline and ensure a continuous and safe operation of the line. A part of this monitoring system is the metering Station at Derialik.

The system covers the full 750 km length of the pipeline with a central command center located in the city of Dashovuz in the north and five regional command centers at various locations along the pipe. Site facilities control the gas flow from 95 wells. The gas is cleaned from H2S and dried in four 500m3/hr primary processing plants, a utilities center and a sulfur recovery plant. The gas is then sent some 2000 kilometers to Russia and to Western Europe through transnational pipeline system.
