Capacity & Construction

After technical meetings and discussion with potential future partners, the Eastring’s route has been suggested to respect mainly the environmental and social sensitive areas whenever possible.

The design and selection process of pipeline components have one of the most significant effects on the project investment. The Eastring Feasibility Study consists of simulations and optimization of construction and capacities, with the initial design of a large diameter pipeline, compressor stations, metering stations and block valve stations.

The Eastring construction includes only an onshore section, which will be 1208 km long.

The Eastring project will be implemented in two phases. Phase I will consist of the construction of a new pipeline and three new compressor stations with the transmission capacity of 20 bcm/year. Phase II will consist of building other five compressor stations with the total transmission capacity of the Eastring project of 40 bcm/year.

The new pipeline will have a diameter of DN1400 (inner diameter approximately 1.378 meters) and maximum operating pressure will be 100 bars. One year after the construction of the pipeline, the presence of the pipeline will be difficult to detect. Only facilities such as the compressor stations, metering stations and block valve stations will be above ground and they will be designed and constructed so as to have minimum negative environmental and social impacts.

The above ground facilities will include three compressor stations for Phase I (20 bcm/year) with units, five metering stations in total, several intrastate delivery stations and block valve stations serving for maintenance purpose, which will be located every 20 - 40 km along the pipeline. These technologies will be used to ensure secure gas transmission in desired amounts and quality throughout the lifetime of the pipeline.
