Significance

The Dzhubga – Lazarevskoye – Sochi gas pipeline has been included into the Russian Government endorsed Program for the Construction of Olympic Venues and the Development of Sochi as a Mountain Climatic Resort.

Dzhubga – Lazarevskoye – Sochi gas pipeline

Dzhubga – Lazarevskoye – Sochi gas pipeline

The gas pipeline construction will help achieve the following objectives:

  • ensure reliable power supply to the Winter Olympic Games host city and deliver natural gas to Olympic venues;
  • promote gasification of the city of Sochi and the Tuapse District, as well as give a powerful impetus to improving the living standards of the population and to developing the resort industry in these regions;
  • considerably cut the energy deficit in the resort area on the Caucasian coast of the Black Sea;
  • improve the environmental situation in the region by replacing environmentally destructive fuels (coal and fuel oil) by the environmentally sound one – natural gas.

Environmental protection

The Dzhubga – Lazarevskoye – Sochi gas pipeline lays the foundation for preserving a healthy environment in a most climatically attractive and, therefore, the most cherished region of the country. The use of natural gas for heat and power generation will contribute to environmental stabilization of the region.

Gazprom paid close attention to environmental protection measures taken during the gas pipeline construction, which complied with all globally accepted standards and rules and involved application of cutting-edge techniques and technologies.

The gas pipeline construction schedule was elaborated with due regard to the most vital biocycles of the local fauna species. This is of great importance for preserving the animal ecosystem.

The offshore option of the gas pipeline route considerably minimized the condemnation of industrial, agricultural and forest lands, as well as lands in specially protected natural reservations.

The impact on the Black Sea ecosystem was minimized through optimum engineering and construction solutions for the offshore section. In particular, the specific features of the sea bottom were taken into account during the pipeline route selection. Prior to the construction start-up, foreign polluting objects were removed from the selected route of the pipeline.

The most suitable coastal line crossing procedure – directional drilling – considerably mitigated the environmental impact on the most vulnerable coastal ecosystems. As a result, it was possible to avoid interference with the habitats of coastal flora and fauna.

The project obtained positive conclusions from the State Environmental Expertise and the State Environmental Expertise Department (Glavgosekspertiza).

Technical features

The gas pipeline stretches for 171.6 kilometers with 90 per cent placed on the Black Sea bottom along the coastal line at the water depth reaching 80 meters.

The gas pipeline landfalls are located near Dzhubga, Novomikhailovskoye, Tuapse and Kudepsta.

The onshore section of the gas pipeline starts near the Dzhubga settlement. Between the Dzhubga and Lermontovo settlements the pipeline onshore and offshore sections are connected.

The 530-millimeter gas pipeline has the annual throughput capacity of some 3.8 billion cubic meters.
