Sakhalin-1 & Sakhalin-2 facilities and pipeline systems

The project of development of oil and gas fields on the shelf of the Okhotsk sea is one of the world's largest integrated oil and gas projects. From 1998 to 2009 have been mastered Chayvo oil and gas field (Sakhalin 1), the Piltun- Astokhskoye and Lunskoye oil and gas field (Sakhalin-2).

Severe climatic conditions reigning in the Far East territory, unique flora and fauna, Red Book species habitat and salmon species fishery called for compulsory compliance with environmental restrains in the implementation of the project.

All these years Environmental Centre IFPA was the main contractor for the environmental aspects of the project - when carrying out exploration, environmental-engineering survey and design.

During the design process were assessed environmental impacts of the following objects oil and gas field:

- Stationary production platform, e.g. Molikpaq
(PA-A), PA-B, Lun-A;

- Routes of Offshore and Onshore Pipelines;
- Liquefied Natural Gas (LNG) Plant;

- Oil Export Terminal (OET);

- Tanker Loading Unit (TLU);

- LNG Jetty;

- Booster Stations;

- The totality of access motorways;

- Temporary Construction Camps.

The following was done to mitigate as much as possible potentially unfavorable environmental impacts on natural resources:

Ice-resistant production platforms used;
Horizontal directional drilling applied for crossing watercourses with fishery potential;
Works performed asynchronously with the periods of biological activity of the fauna’s species;
Post-construction reclamation performed.
