The Natural Studies at the Bovanenkovo - Baydaratskaya Bay Route for the Provision of Investigations on the Reliable Operation of Gas Pipelines in Yamal.

摘要

A system of main gas pipelines is designed from the Bovanenkovo gas and condensate field. It will consist of three lines with 1420 mm in diameter and 11.8 MPa pressure, laid on the peninsula with transition across Baydaratskaya Bay. The five-line transition across the bay is assumed to consist of pipes with 1220 mm in diameter. The route is laid on permafrost with the temperature of -6...-7°C across the whole length. The water content of grounds reaches 80%. The ice content is 15-30%. Ice massifs reach the thickness of several tens of meters; cryopegs are found. The route crosses multiple rivers and creeks falling into the Kara Sea. The natural conditions at the site of crossing of Baydaratskaya Bay are very complex as well.
