Improving the reliability of pipelines

An integrated approach forms the basis for improving the operational reliability of pipelines in PJSC LUKOIL. Main measures include:

  • Pipeline maintenance and repairs
  • Overhauls of field and main pipelines
  • Appraisals of industrial safety and technical diagnostics
  • Renovation of field and main pipelines, including corrosion-resistant pipelines
  • Inhibitory and electrochemical protection to ensure the operation and extend the service life of pipelines

In 2018, almost half of pipeline renovation activities were carried out in West Siberia, as this region accounts for 44% of pipelines.

PrioritiesPriorities are determined in accordance with Federal Law No. 22 -FZ dated March 4, 2013 "On the Industrial Safety of Hazardous Production Facilities," which sets out the classifcation of pipelines into hazard classes. when it comes to implementing the concept of enhancing the operational reliability of pipelines include: inhibition, the use of non-metallic pipelines, and introducing corrosion-resistant pipes. The main focus is on pipelines of the first (highest) hazard class.

Options are considered to use alternative materials, including non-metallic pipes, in conditions of highly corrosive environments. These materials can be used to construct pipelines of the fourth hazard class (which include discharge lines), taking into account the bearing capacity of the soil. If optimal solutions are found, they can be also be applied in permafrost conditions.

Major efforts are made to prepare pipelines for the autumn-winter season and for floods, which includes maintaining hydraulic locks (oil separators) in working order so as to reduce the likelihood of spills. In order to reduce the number of spills, the frequency of bypasses is increased, especially with regard to potentially hazardous areas that may be exposed to melt water and rain.
