The DRUŽBA international oil pipeline is one of the world's longest oil pipelines (5,000 km), starting in central Russia's Almatyevsk (Samara region – the city of Samara), where oil is harvested from Kazakhstan, the Caucasus and western Siberia. The pipeline then heads towards Russia's western border, where it is divided in the city of Uneča. It is divided into a branch continuing along the territory of Belarus through Polovo and the Baltics to the ports of Lithuania and Latvia and a branch of the SATELLITE further to Mozyr, Belarus. Here, THE DRUŽBA is divided into a northern branch pointing to Poland and a southern branch, which continues through Brody to the Ukrainian village of Grand Geyevce, where it is divided into a branch pointing to Slovakia and the Czech Republic and a branch to Hungary.
The route of the pipeline starts in the Slovak Republic on the Ukrainian-Slovak border in the municipality of Ruská, continues through the pumping stations PS1 Budkovce, PS2 Moldava nad Bodvou, PS3 Rimavská Sobota and PS4 Tupá, where the Adria pipeline also operates. The Adria pipeline starts in the Croatian port of Omišalj, continues through Croatia and Hungary and enters Slovakia in the municipality of Tešmak. The main branch of the pipeline route in the Slovak Republic continues from PS4 Tupá to PS5 Bučany, where it is divided into two branches. One is heading to Slovnaft in Bratislava, where it is completed by the Oil Transfer Station in slovnaft, a. s., the other is heading northwest to the Czechoslovak border, where the route on the Slovak side ends in the cadastre of the village of Kátov near the Morava River.
The length of the territory in Slovakia through which the oil pipelines pass is about 510 km. The pipeline is duplicated in most of the territory, except for the section of the Adria pipeline, the section between PS5 Bučany and Slovnaft Bratislava and the section from the terminal in the cadastre of radošovce.
At the Slovak-Ukrainian border at the pumping station PS1 Budkovce is located the Oil Measuring Station (MSR), which measures the amount of oil taken over from the Russian transport company PAO TRANSNEFT with the participation of the Ukrainian transport company AT UKRTRANSNAFTA.
MSR for oil supplied to the Czech Republic is located on PC 26 Klobouky u Brno (belonging to spol. MERO ČR) and control measurements are carried out on MSR at the pumping station PS5 Bučany.
MSR for oil supplied by a. s. Slovnaft is located in the Oil Transfer Station in the area of spol. Slovnaft.
Since pipelines owned by TRANSPETROL, a. s., are among the strategic elements of the Slovak economy, continuous protection and security of the oil pipeline system is ensured by security systems and elements.
