The first intrarussian offshore gas pipeline Dzhubga–Lazarevskoye–Sochi was put into operation in Sochi on June 6. The ceremony dedicated to this event was attended by Russian Prime Minister Vladimir Putin, Chairman of the Gazprom Committee Aleksey Miller, and representatives of construction companies, contractors, and public members.
The gas pipeline’s length is 171.6 km, with its offshore section accounting for 90%. The pipeline traverses the Black Sea, running parallel, approximately 4.5 km from the Russian coast.
All the pipes for the gas pipeline were made by Vyksa Steel Works (VSW, Nizhni Novgorod Region), part of United Metallurgical Company (OMK). They can withstand pressures up to 9.8 MPa. All in all, 49,951 tonnes of pipes were supplied for the construction of the Dzhubga–Lazarevskoye–Sochi gas pipeline.
“ At present, owing to the investment in the renovation of pipe facilities, our Company can produce pipes at any complexity level, including pipes for such subsea gas pipelines as Dzhubga–Lazarevskoye–Sochi. All the pipes underwent obligatory certification and have unique characteristics. This is not our first experience in the production of pipes designed for subsea gas pipelines. OMK supplied its pipes for the Baydaratskaya Bay and Nevelski Strait gas pipelines, and in May the Company finished its pipe shipments for Phase 2 of the Nord Stream gas pipeline. We supplied a total of 360 thousand tonnes of pipes for Europe’s largest subsea gas pipeline, ” said OMK President Vladimir Markin.
