Aug 4 (Reuters) - Here are some key facts on major oil or gas pipelines in central and southeastern Europe:
* NABUCCO - On July 13, European Union countries and Turkey signed a key transit deal for the 7.9 billion euro ($11.05 billion) Nabucco gas pipeline aimed at cutting Europe's energy dependence on Russia.
The United States-backed project aims to transport gas from the Caspian and Middle East via Turkey, Bulgaria, Romania, and Hungary to central Europe.
Construction of the 3,300-km (2,050 mile) pipeline is scheduled to start in 2011 and first deliveries are expected in 2014 with an initial annual capacity of 8-10 bcm.
Austrian oil and gas group OMV heads the consortium which includes Hungary's MOL, Turkey's Botas, Bulgaria's Bulgargaz, Romania's Transgaz, and German utility RWE.
It could transport up to 31 bcm of gas a year from Central Asia and the Middle East to Europe by 2020, reducing dependency on Russian gas, and may be used to bring Iranian gas to Europe.
* SOUTH STREAM - Gazprom and Italian oil firm Eni plan to build a 10 billion euro ($13.53 billion) pipeline, seen as a rival to Nabucco, to take Russian gas under the Black Sea to south-eastern Europe, avoiding Ukraine with which Russia has had pricing disputes.
* PAN-EUROPEAN OIL PIPELINE (PEOP) - Due to start operating in 2012, will connect the Romanian port of Constanta with Trieste in Italy, via Serbia, Croatia and Slovenia. The 1,400 km long pipeline, worth between $2 billion and $3.5 billion, will supply refineries in northern Italy and central Europe with crude from the Caspian. It will have an annual capacity of 1.2-1.8 million barrels per day (bpd).
* BAKU-TBILISI-CEYHAN - The $4 billion BP-led pipeline was opened in June 2006. Its capacity is one million bpd of Azeri crude. It ran 1,770 km to Turkey's Ceyhan port in 2008. It is the first pipeline to carry large volumes of crude from the Caspian without going through Russia.
* CASPIAN PIPELINE CONSORTIUM (CPC) - Connects Kazakhstan's Caspian Sea oil deposits with Russia's Black Sea port of Novorossiisk. Although the 1,510-km CPC pipeline transverses Russia and was developed in conjunction with the Russian government, it was the first to give the Caspian Sea region and Kazakhstan a viable alternative to the Russian dominated northern export routes. Its shareholders plan to double CPC's annual capacity from 33 million tonnes by 2013.
* DRUZHBA - Russia's Druzhba (Friendship) oil pipeline starts in Russia's Samara and ends in the northern Adriatic port of Omisalj in Croatia, connecting Germany, Poland, Hungary, Slovakia and the Czech Republic. It has a planned capacity of over 2 million bpd, of which 1.4-1.6 million bpd go directly to consumers in the European Union and the rest stays in Belarus.
The Druzhba splits into two legs with the bigger northern leg going to Poland and Germany and the southern leg supplying Slovakia, Hungary and the Czech Republic. One fifth of German supplies arrive via the Druzhba pipeline.
* BALTIC SEA PIPELINE - The 7.4 billion euro gas pipeline would run 1,200 km from Vyborg in Russia to Greifswald in Germany under the Baltic sea.
The Nord Stream, majority owned by Russian gas monopoly Gazprom, is building the pipeline with Germany's BASF and E.ON and Dutch company Gasunie and has plans to build two parallel gas pipeline legs of 750 miles (1,200 km) each, the first by 2011 and the second by 2012. Total annual capacity will be 55 bcm.
* CENTRAL ASIA GAS PIPELINE SYSTEM - Russia, Turkmenistan and Kazakhstan have agreed plans for a new natural gas pipeline around the Caspian Sea to deliver up to 20 bcm of gas per year by 2009-2010. Critics say the deal tightens Russia's grip on gas exports from the region, while Moscow says it will create additional routes to the European Union.
