Restoring the right-of-way along the 800 km Transsakhalin pipeline, one of the world's largest oil and gas projects Begun in 1994, Sakhalin-2 is considered one of the world's largest integrated oil and gas projects. It was conceived to develop and produce oil and gas from two fields off the shores of Sakhalin Island for delivery to the rapidly growing Asia-Pacific market. The project includes three offshore drilling platforms, offshore pipelines onshore processing facilities, an oil export terminal, Russia's first liquefied natural gas (LNG) plant and the 800 km onshore TransSakhalin pipeline system. Completed in 2008, Sakhalin Energy is required to monitor site restoration and right-of-way reinstatement along the pipeline system. Program requirements were outlined in accordance with the Environmental Impact Assessment and Technical Analysis on disturbed lands and habitat reinstatement, defined before the project had commenced. Sakhalin-2: one of the world's largest oil & gas projects SAKHALIN-2 OIL & GAS RIGHT- OF-WAY RESTORATION PROJECT info@maxar.com maxar.com Challenging terrain The TransSakhalin pipeline was constructed in the area known for its severe natural and climatic conditions: rugged topography, complex geology and hydrography, increased seismic activity and a fragile ecosystem. The task of recovery and restoration is challenging, but a high priority for the company. "Access to a significant part the pipelines right-of-way is constrained by steep terrain, making ground based observations very difficult," says Egor Levkovsky, company Leading Environmental Specialist. "Therefore remote sensing data is very important for identification, development and assessment of reinstatement efforts. Moving forward, we also required a methodology to measure the effectiveness of these efforts to help design yearly scope of work and ongoing mitigation actions." company information Sakhalin Energy Investment Company Ltd.
