What Is the Druzhba Pipeline and Why Does It Matter?
The Soviet-era Druzhba pipeline remains Europe's largest crude oil artery — and a flashpoint in the continent's struggle to break free from Russian energy dependence.
The Druzhba pipeline transports Russian crude oil across 4,000 kilometres from Tatarstan to Central Europe, making it one of the world’s longest oil networks and a critical — yet politically fraught — supply route for landlocked EU states.
Built during the Cold War to cement Soviet influence over Eastern Europe, the pipeline today stands at the centre of Europe’s most acute Energy security dilemma. According to Global Energy Monitor, the system spans approximately 8,900 kilometres including all branches, with a designed capacity of 1.2 to 1.4 million barrels per day. At its peak, it pumped over 1 million barrels daily — roughly 1% of global oil supply — though flows have dropped sharply since Russia’s 2022 invasion of Ukraine.
The pipeline’s name translates to “Friendship” in Russian, a reference to the collaborative construction project that united Communist states in the 1960s. Today, that symbolism rings hollow: the Infrastructure has become a lever of geopolitical pressure, a target for military strikes, and the subject of bitter disputes between Ukraine, Hungary, Slovakia, and Brussels.

How the System Works
The Druzhba network originates at Almetyevsk in Tatarstan, where it collects crude from Western Siberia, the Urals, and the Caspian Sea. From there, the pipeline runs 4,000 kilometres to Mazyr in southern Belarus, where it splits into two distinct branches serving different markets.
The northern branch crosses Belarus and Poland to Schwedt in Germany, supplying refineries at Płock and Schwedt. Following Germany’s decision to cease Russian oil imports in January 2023, according to Wikipedia, this route now carries only Kazakh crude — approximately 1.2 million tonnes per year under agreements reached in December 2023.
The southern branch runs through Ukraine, where it splits at Uzhhorod into two sub-lines: Druzhba-1 continues to Slovakia and the Czech Republic, while Druzhba-2 serves Hungary. This southern leg remains the primary source of contention, as Hungary and Slovakia continue to rely heavily on Russian crude delivered via Ukrainian territory.
The pipeline crosses 45 major rivers and uses a network of 46 pumping stations to maintain pressure throughout the system. Pipe diameter varies from 420 to 1,020 millimetres, and the system operates 24 hours daily at pressures exceeding 70 atmospheres, according to Beltps.
The Soviet Construction Project
On 18 December 1958, the Council for Mutual Economic Assistance (Comecon) convened in Prague and approved construction of a trunk oil pipeline from the USSR to Poland, Czechoslovakia, East Germany, and Hungary. Construction commenced in December 1960, with each participating country responsible for designing, building, and maintaining its own section.
The division of labour reflected Cold War industrial specialisation: the Soviet Union and Poland manufactured pipes, Czechoslovakia produced valves and fittings, East Germany supplied pumps, and Hungary provided automation and communications equipment. The initial 5,327-kilometre line cost nearly 400 million rubles and required 730,000 tonnes of steel pipe.
The first oil reached Czechoslovakia in 1962, Hungary in September 1963, Poland in November 1963, and East Germany in December 1963, as documented by Global Energy Monitor. The full system entered operation in October 1964. In the 1970s, the network was expanded with parallel lines — dubbed “Druzhba-2” — that more than doubled export capacity.
Who Depends on Druzhba Today
The pipeline’s strategic importance has diminished dramatically since 2022, but it remains critical for two landlocked EU member states: Hungary and Slovakia.
Hungary sources 86% of its crude oil from Russia via Druzhba, up from 61% in 2021, despite EU-wide efforts to reduce Russian energy dependence, according to analysis by The Moscow Times. Hungarian oil giant MOL operates refineries at Százhalombatta that process approximately 5.75 million tonnes of crude annually. Slovakia’s Slovnaft refinery, also owned by MOL, handles 4.66 million tonnes per year and is configured specifically for Russian crude grades.
The Czech Republic, by contrast, ceased Russian oil imports in April 2025 after expanding its western supply route via the Transalpine pipeline from Trieste, Italy. Poland stopped Druzhba imports in February 2023. Germany halted purchases in January 2023, though it now receives limited volumes of Kazakh crude via the northern branch.
Belarus continues to receive Russian oil for its Mozyr and Naftan refineries. Latvia and Lithuania’s branches — which once supplied the Ventspils terminal and Mažeikiai refinery — ceased operation in 2006 and are unlikely to restart.
| Country | Status | Russian Oil Share |
|---|---|---|
| Hungary | Active | 86% |
| Slovakia | Active (halted Jan 2026) | ~100% |
| Czech Republic | Ceased Apr 2025 | 0% |
| Germany | Kazakh only (Dec 2023) | 0% |
| Poland | Ceased Feb 2023 | 0% |
Sanctions, Exemptions, and Geopolitical Leverage
When the EU imposed an embargo on Russian seaborne crude in December 2022 following the full-scale invasion of Ukraine, landlocked Hungary, Slovakia, and the Czech Republic secured an exemption for pipeline deliveries. Brussels described the carve-out as temporary, urging the three countries to diversify “as soon as possible.”
The Czech Republic complied by 2025. Hungary and Slovakia have not. Both countries secured open-ended exemptions that remain in force, and both have resisted EU pressure to accelerate diversification. Budapest has blocked multiple sanctions packages and financial assistance measures in retaliation for perceived threats to its oil supply.
Alternative routes exist. Croatia’s Adria (JANAF) pipeline connects the Adriatic port of Omišalj to refineries in Hungary and Slovakia, with a stated capacity of 280,000 barrels per day — enough to replace the approximately 200,000 barrels per day that flowed through Druzhba’s southern branch in early 2026, according to DD News. Croatia has offered to facilitate non-Russian crude shipments but has refused to transit Russian oil through its infrastructure.
Hungary’s MOL disputes Adria’s capacity claims and argues that higher Croatian transit fees make the route economically unviable. Critics counter that Budapest’s reluctance is political rather than technical: MOL’s operating income rose 30% above pre-invasion levels as the company purchased discounted Russian crude but sold refined products at market prices, according to research by CNN citing the Center for the Study of Democracy.
In January 2026, the EU adopted legislation requiring all member states to phase out Russian fossil fuels by 2027. Hungary and Slovakia have filed legal challenges against the law, and both countries continue to block EU decisions on Ukraine aid and Russia sanctions until oil flows via Druzhba resume following damage to the pipeline in late January 2026.
Ownership and Operators
Under the original Comecon agreement, each country owns the section of pipeline within its borders. The Russian segment is operated by state-owned Transneft through its subsidiary Transneft Druzhba. In Belarus, Gomeltransneft Druzhba operates the network. Ukraine’s section is managed by UkrTransNafta.
Downstream, PERN Przyjazn SA operates the Polish segment, Transpetrol AS manages the Slovak section, Mero handles the Czech Republic’s infrastructure, and MOL oversees the Hungarian system. Each operator is responsible for maintenance, pumping stations, and compliance with national regulations.
A 2019 ten-year transit contract between UkrTransNafta and Transneft governs Russian oil shipments through Ukrainian territory. Under the deal, Ukraine earns approximately $150 million annually in transit fees, while Russia generates an estimated $6 billion per year from oil deliveries through Ukraine, according to Global Energy Monitor.
Why Europe Built Alternatives
Russia anticipated the geopolitical vulnerability of transiting oil through Ukraine and Belarus. In 2009, construction began on the Baltic Pipeline System-2 (BPS-2), a 50-million-tonne-per-year line running from the Unecha junction near the Russia-Belarus border to the Ust-Luga terminal on the Gulf of Finland. The system became operational in March 2012.
The BPS-2 allows Russia to bypass both Ukraine and Belarus entirely, exporting crude directly to tankers at Baltic ports. The pipeline reduces Moscow’s dependence on Druzhba for westward crude exports and limits the leverage that transit countries historically held over Russian energy shipments.
For Europe, diversification has proceeded unevenly. Poland now relies on seaborne deliveries via Gdańsk. Germany sources alternative crude through the MVL pipeline network. The Czech Republic expanded capacity on the Transalpine pipeline, which carries crude from Italy through Austria. Each of these routes required years of investment and infrastructure upgrades — investments that Hungary and Slovakia have declined to make.
Vulnerability and Attacks
The pipeline has experienced multiple disruptions. In April 2019, deliveries were halted after high concentrations of organic chloride contaminated the system, causing billions of dollars in economic damage. Russian authorities detained eight individuals suspected of stealing oil and pouring organochloride into the pipeline to cover up the theft.
Since Russia’s 2022 invasion, the pipeline has become a military target. In August 2025, Ukrainian drones struck the Unecha junction and Nikolskoye pumping station in Bryansk Oblast, causing fires and temporarily halting flows. Attacks continued through the autumn, with further strikes on Russian pumping infrastructure documented by NASA’s Fire Information for Resource Management System (FIRMS).
On 27 January 2026, a Russian drone strike damaged the Brody pumping station in Ukraine’s Lviv region, halting oil flows to Hungary and Slovakia. Ukrainian Foreign Minister Andrii Sybiha posted photographs of the burning facility and cited force majeure, explaining that destruction of high-pressure pumps and control systems made continued transit physically impossible.
Hungary and Slovakia accused Ukraine of deliberately delaying repairs for political reasons. On 23 February 2026, both countries blocked the EU’s 20th sanctions package against Russia. Budapest also vetoed a €90 billion EU loan to Ukraine, demanding restoration of oil flows as a precondition, according to Wikipedia.
