ST PETERSBURG, Russia – Gazprom Neft has commissioned a 58.4-km (36.3-mi) subsea pipeline that crosses the Gulf of Ob in the Kara Sea, offshore northern Russia.
The new system connects onshore gas production facilities on the Yamal peninsula to the overland Yamburg-Tula trunkline, which will deliver gas from the Novoportovskoye field to Russia’s Unified Gas Supply System (UGSS).
Commissioning of the new subsea line also opens the potential for further nearby cluster field developments, Gazprom Neft said.
A new onshore complex for processing natural gas and condensate is under construction as part of the project.
The trunkline’s subsea section is installed 5 m (16.4 ft) below the seabed, safeguarding the local environment against disruption from noise, vibrations and electromagnetic pulses, the company added.
And the system has been engineered to avoid any risk of thawing the permafrost. The nearby Novy Port population center will be connected to the gas network.
Novoportovskoye is one of the largest oil and gas condensate fields under development on the Yamal peninsula, with estimated recoverable reserves of 248MM metric tons (273MM tons) of oil and condensate, and 266 bcm of gas.
