Prevention of spills at sea

Oil field development offshore is technologically more complicated than onshore, and, therefore, requires special attention and efforts to ensure the reliability of equipment and the safety of operations.

For over 15 years, LUKOIL has been operating offshore facilities (terminals, oil and gas production platforms, subsea pipelines) accident-free. This is the result of the Company’s highly responsible approach to safety and preservation of marine resources.

Our actions

LUKOIL’s system of in-house regulations and internal standards and procedures accords with the Safety Rules for Offshore Oil and Gas Facilities of the Federal Service for Environmental, Technological and Nuclear Supervision (Rostekhnadzor) and the Rules of the Register for classification and construction of offshore fixed platforms and Pipelines of the Russian Maritime Register of Shipping This organization is a full member of the International Association of Classification Societies and oversees compliance with the maritime law and the requirements of international conventions for offshore facilities. . Construction and operation of offshore facilities is permitted upon availability of statements of compliance with these requirements and based on permits issued by state authorities.

PJSC LUKOIL has developed Methodological Guidelines for ensuring reliability of offshore pipelines and corporate standards, which contain even more stringent safety requirements as compared to the Russian legislation. There is also a standard operating procedure in effect, which provides for the classification of well defects and the rules for their repair. Starting from 2018, all work has been performed in accordance with these documents.

Design and construction

Design, construction, maintenance, diver inspection, and repair of offshore facilities are carried out by specialized service organizations that are selected through tender procedures and technical audits. At the design and construction stage, LUKOIL assesses compliance of design and working documentation with reliability and safety requirements by engaging independent expert organizations. All well construction work at the fields is performed by contractors under the supervision of LUKOIL Group entities through drilling supervisors (working directly on drilling platforms) and production engineers (working from the office).

In accordance with the Oil and Oil Product Spill Prevention and Response Plans, special vessels with full equipment for emergency management (under a contract with professional emergency rescue teams) are on 24-hour duty around all LUKOIL’s offshore facilities.

Well condition monitoring

Wells are assessed and monitored during downhole operations using instruments that assess the condition of downhole equipment and the string operation (pressure and temperature sensors and devices for measuring other parameters). The operation and condition of the equipment are monitored 24 hours a day; the measurement results are sent to the remote-control system, which is constantly monitored in the presence of service personnel.

Offshore pipeline monitoring

Every year, diver inspections of subsea pipeline routes and work to maintain their proper technical condition are carried out. In-line and visual diagnostic methods are used: pipeline wall thickness is measured, metal loss/stratification and equipment spatial positioning are assessed, and corrosion monitoring systems are installed. The results of inspections are entered into databases for GIS applications. The frequency of inspections is strictly regulated by industry legislationRussian Maritime Register of Shipping "The Guidelines on Technical Supervision during Construction and Operation of Subsea Pipelines. Regulatory Document No. 2-030301-002" and corporate standards.

There was no need to replace pipelines during the entire life of the projects at the Northern Caspian and Baltic fields. LUKOIL adopted the new Russian technology “Beluga”, which can be used to perform repairs without stopping the pumping of the product.

In order to avoid environmental risks, a safety system is in place to ensure a high degree of protection of the marine environment from the possible negative impact of production operations.

Zero Discharge

The main principle of offshore work is Zero Discharge, which prohibits disposal of any type of waste generated as a result of production activities into the marine environment. All waste is collected in hermetically sealed containers, which are then transported to the shore for decontamination and disposal.

Environmental and Satellite Monitoring of Offshore Zones and Shorelines

In Russia, LUKOIL-Kaliningradmorneft and LUKOIL-Nizhnevolzhskneft entered into contracts with specialized organizations for continuous environmental monitoring of the waters of the Baltic and Caspian seas within the boundaries of the licensed subsoil areas.

Platforms in the Caspian Sea

The duty rescue vessels Langepas and Kogalym are on duty around the LUKOIL platforms in the Caspian Sea. In 2020, new equipment to localize and eliminate emergency oil spills was purchased for them. The Speed Sweep allows cleaning the oil film from the water surface at a higher speed. This technology goes down from the vessel and does not require the use of a loader crane and auxiliary equipment, all of which all of which increase the response speed.
