Transpetrol is a quite young oil pipeline company. The historic roots of its foundation are bound with the Druzhba transit pipeline, its southern branch, which enters from the former Soviet Union area, through Belarus and the Ukraine into former Czechoslovakia. Slovak part of the Druzhba pipeline, from the Ukrainian border through Šahy to Bratislava, was built in 1960 – 61. First crude oil was transported to the crude oil terminal Slovnaft in Bratislava by the Druzhba oil pipeline in February 1962. The next stage of the oil pipeline Druzhba building, finished in 1968, focused on intensifying of the pipeline system by doubling of the pipeline length, thereby transporting capacity, operation reliability and safety of the central transit corridor of the pipeline significantly increased.

In 1980 the Adria pipeline got going. It continues from the Croatian port Omišalj on the coast of the Adriatic Sea, through Hungary and finishes in Šahy in Slovakia, where it links to the Druzhba oil pipeline. Then it became a part of Czechoslovak crude oil pipeline system and its operation created important preconditions for diversification of crude oil supplying and other possibilities for entering new crude oil markets.

After the change of social – political and economic circumstances in former Czechoslovakia, the Czechoslovak joint stock company Transpetrol was established by property deposit of the original crude oil pipeline system on 1 July 1991 and it undertook the obligation to operate the whole oil pipeline network in the area of Czechoslovakia. After Czecho – Slovak separation and the establishment of two independent states also the joint stock company was divided into two independent companies. MERO ČR was set up in the Czech Republic and in Slovakia it was a joint stock company with the original name Transpetrol which was created on 1 January 1993.
