OREANDA-NEWS. August 13, 2008. Gazprom has launched the construction of the most difficult section along the Bovanenkovo – Ukhta gas trunkline system – a submerged crossing via the Baidarata Bay.

1,219 mm steel pipes being used for the submerged crossing construction have 27 mm wall thickness and are designed for 120 atm pressure. The pipes were made and encased in concrete by domestic companies. All the marine operations are also being effected by a Russian company.

Laying gas pipes with such technical parameters in the Baidarata Bay remarkable by its specific environment will be the first project of this kind not only in Russia but also in the world practice.
