Safe Operation of the Oil and Petroleum Products Trunk Pipeline Transportation System
1Safety of pipelines and facilities, as well as safety during transportation of oil and petroleum products
3Quality of construction of the facilities belonging to the oil and petroleum products trunk pipeline transportation system
WHY THESE TOPICS MATTER
Transneft is a key element of the fuel and energy system of the Russian Federation; the Company has a significant impact on the state of industrial safety and energy security of the industry.
In order to prevent accidents and emergencies, Transneft Group is building a system for ensuring safety and security of operational facilities. When operating its facilities, the Group strictly complies with the applicable Russian laws and international standards.
When building and revamping its facilities, the Group focuses on continuous development of the oil and petroleum products trunk pipeline transportation system with a high level of quality and safety.
Transneft’s Industrial Safety Goals:
- creating the conditions for protecting the life and health of the Company’s employees;
- creating the conditions for protecting the life and health of the population against incidents and emergency events at hazardous operational facilities;
- reducing the risk of accidents and associated environmental effects.
- The ISO 9001:2011, international standard for Quality Management Systems;
- The GOST-R ISO 9001-2008, national standard for Quality Management Systems;
- Transneft’s Policy in Occupational Safety, Energy Efficiency, Industrial and Environmental Safety;
- Transneft’s Strategy up to 2020;
- Transneft’s Long-Term Development Programme;
- The Construction Quality Policy;
- The Development, Technical Upgrading and Revamping Programme for Transneft’s Trunk Pipeline Facilities (an integral part of the LDP);
- Transneft’s Security Policy.
Industrial safety is understood as security of key individual and public interests against accidents that may occur at hazardous operational facilities, as well as their after effects. Industrial safety includes measures aimed at preventing (minimising) the after effects of accidents at operational facilities.
Transneft’s Expert Council for Security Issues is a platform for discussing and finding solutions concerning safe operation of pipeline transport.
Meetings of the Expert Council
In 2018, two meetings of the Expert Council were held, addressing such issues as import substitution and promotion of the Company’s technologies and services to foreign markets in the context of ensuring the economic security of pipeline transportation facilities. In addition to that, the state and prospects of Transneft’s interaction with government authorities and law enforcement agencies were discussed in view of the tasks needing to be handled in the field of security of oil and petroleum products trunk pipeline transportation facilities.
ASSESSING THE MANAGEMENT EFFICIENCY
The degree of reliability of Transneft Group’s operating facilities is monitored through comprehensive inspections of pipelines and pumping stations in order to timely detect all unreliable elements and potential defects, as well as to calculate the safe operation period for each facility. Inspection of the Company’s industrial facilities is performed by a specialised company, Transneft Diascan.
Airborne Laser Scanning at Transneft East
Transneft Group utilises the airborne laser scanning method to monitor pipeline performance. The method consists of aerial surveys using laser equipment and land surveying. During airborne laser scanning, special high-precision photo, video and laser equipment records and reads the data of the terrain, the inclines and slope exposure. As a result, data are collected on the shape and location of pipeline sections, which allows for monitoring of the stability of its positioning.
The purpose of the procedure is to ensure efficient and safe oil pipeline operation. The pipelines’ operating conditions are adjusted on the basis of the information thus collected, as necessary.
In 2017–2018, more than 900 devices were installed on Transneft East’s oil pipelines to determine the pipelines’ horizontal location and elevation using this technology. Specialists from Transneft East examined about 2,700 kilometres of line of the Eastern Siberia – Pacific Ocean (ESPO) oil pipeline and nearly 700 kilometres of the Kuyumba – Tayshet oil pipeline in 2018.
Deep Submergence Pressure Chamber (GK-25)
Transneft is utilising a deep submergence pressure chamber (GK-25) for inspecting oil trunk pipelines at up to 25 m deep underwater crossings. The GK-25 pressure chamber is a multi-purpose specialty repair and maintenance unit.
In 2018, this equipment was used at the underwater crossing of the Kholmogory – Klin pipeline across the Ob River, which transports about 70 million tonnes of oil per year. During a scheduled inspection, a defect (a dent) was discovered at the 328th kilometre of the pipeline, and it was resolved that GK-25 would be used to eliminate the defect
Robotic Device for Inspection of Pipelines
The concept of a robotic unit for inline inspection of process pipelines has been developed at Transneft. Nowadays, external inspection methods are used to examine process pipelines, which requires plenty of earthwork, as well as removal and subsequent restoration of the protective coating of the process pipelines.
On 19 March 2019, an agreement on the development of an innovative inspection tool for performing diagnostic inspection of process pipelines was signed between Transneft, Transneft Diascan, the Fund for Infrastructure and Educational Programmes of RUSNANO, and Tubot.
The robotic unit will automate the process of diagnostic inspection on process pipelines at Transneft Group’s oil pumping stations and help timely detect pipeline defects. An inline robot will be able to independently pass T-couplings and offshoots, as well as to do pre-inspection cleaning of pipelines.
EMERGENCY CONTROL AUTOMATION SYSTEM
A centralised emergency control automation system (hereinafter referred to as CECAS) has been introduced at Transneft Group. This technology improves the pipeline system’s operational safety and minimises risks during transportation of oil and petroleum products. The Group intends to put all the existing pipelines under CECAS control within the scope of the programme for pipeline transportation facilities’ development and revamping.
In 2018, Transneft North commissioned a new CECAS installed on the Usa – Ukhta oil trunk pipeline (OTP), while the existing CECAS running on the Ukhta – Yaroslavl OTP was modified to comply with the requirements of the unified supervisory control system. Today, all process sections of Transneft North’s trunk pipelines are equipped with CECAS.
In 2018, Transneft Baltic put CECAS into operation on the following oil trunk pipelines: the Yaroslavl – Kirishi-1 OTP, the Palkino – Primorsk OTP the Kstovo – Yaroslavl – Kirishi – Primorsk petroleum products trunk pipeline (PPTP) and the Yaroslavl – Primorsk-2 PPTP.
Specific accident rate is the key indicator characterising the reliability of the trunk pipeline system.
REVAMPING AND MODERNISATION
Transneft Group is upgrading its operational facilities and developing innovative engineering solutions. The Company’s standards in this area match the best international practices. The Company’s capital investments in the construction and revamping of pipelines from 2006 to 2023 will amount to about RUB 5 trillion. Approximately 28,000 kilometres of pipeline and more than 1,500 tanks will be built and upgraded.
CONSTRUCTION OF OIL AND PETROLEUM PRODUCTS TRUNK PIPELINE TRANSPORTATION FACILITIES
The Construction Quality Policy is in place at Transneft. The document applies to all business units of Transneft and its subsidiaries and is also taken into account in the Company’s business relations with partners.

Eastern Siberia – Pacific Ocean Project Management Centre (PMC ESPO, a Transneft subsidiary) won the corporate contest in construction quality based on the 2018 performance.
This organisation implements Transneft’s major investment projects in Russian regions. In Irkutsk Region, three oil pumping stations are being built as part of the second stage of expanding the throughput capacity of the ESPO pipeline system up to 80 million tonnes of oil per year. In Khabarovsk Territory and Primorye Territory, Amur Region and Jewish Autonomous Region, a project is being implemented to expand ESPO-2 up to 50 million tonnes of oil per year.
