Management of Geo-ecological Risks of Oil and Gas Facilities by Means of the Database of Dangerous Geological Processes (Using the Trans-Sakhalin Pipeline System as an Example)

The most common hazardous geological processes affecting the right-of-way of the trans-Sakhalin pipeline system (within the Sakhalin-2 Project), primarily in the Makarovsky District, are considered, and the prerequisites for their development are listed. A database of these processes was created and the results of visual inspection of the pipeline route for oil spills were described. The adequacy of monitoring and reclamation activities along the study area was analyzed. It is found that sections of the trans-Sakhalin pipeline system exposed to hazardous geologic processes were considered during design and construction of the facility and are subject to monitoring and regular maintenance. A conclusion is made about the exposure of the pipeline system to geo-ecological risks, and a forecast of the technical condition of the study object with necessary recommendations is given.
