Stroygazmontazh will lay 84 km of pipeline – the first 58 km of the second string, as well as a 26 km section from the gas treatment plant to the Baydaratskaya Bay crossing on the Yamal Peninsula.

The company said that construction will be highly complex as the pipe will be laid in ground subject to permafrost, and because the site is a considerable distance from the procurement and support bases.

Gazprom’s approximately 1,200 km Bovanenkovo – Ukhta gas pipeline has a design capacity of 140 Bcm/a, and is part of a the Yamal megaproject, a multi-line gas transmission system that aims to deliver gas from the Yamal Peninsula – including from the Bovanenkovo field – to central Russia.

The installation of insulation will increase the pipeline’s 56 inch diameter to 64 inches in some sections.

Stroygazmontazh will begin construction in the first quarter of 2012 and expects the project to reach completion in the second quarter of 2013.
