Natural Gas Giant Gazprom Starts Challenging Subsea Pipeline Construction

Gazprom said that it has started the construction work of the challenging section along the Bovanenkovo – Ukhta gas trunkline system – a subsea pipeline crossing via the Baidarata Bay. The Baidarata Bay is a gulf in the southern Kara Sea, situated between the continental coast and the Yamal Peninsula.

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.
