High Pressure Gas Pipeline in Artic Conditions

More than 2000 km north of Moscow, in the Timan-Pechora Region, the Kharyaga Oil Field is located. Gas is transported through a 9.5 km long 6" pipeline with an operating pressure of up to 356 bar to a field injection well and is reinjected into the reservoir.

The installations are erected in artic conditions, with ambient temperatures of down to –56 °C. The pipeline is laid above ground on piled supports, heat insulated in permafrost conditions. Due to environmental conditions the construction of pipelines is carried out during winter season. A particular difficulty for the design was the fact that Russian as well as Western norms and standards for design and material selection had to be fulfilled. In October 2003 the pipeline has been successfully pressure tested with a pressure of 534 bar and put in operation.
