Nabucco pipeline was proposed to enter Bulgaria and after running in parallel to the existing gas system connect to the Bulgarian national gas network at the compressor station of village Lozenets in Yambol Province. After crossing the Balkan Range, the pipeline will head in a northwesterly direction. After reaching the national northern half-ring, it will run in parallel to the existing east–west gas line and continue to northwest before reaching the Danube at Oryahovo. In Bulgaria, Nabucco will have interconnections with the national gas network and will have two off-take systems, compressor stations and pig stations. In Romania, the pipeline would be crossing into the country under the Danube. The route on the Romanian territory would go from south-west to north-west, its south-western starting point being located at the Danube-crossing point upstream the Port of Bechet, and the north-western end point being located north of Nădlac. The pipe would follow the south western border of Romania and will travel through the counties of Dolj, Mehedinți, Caraș-Severin, Timiș, and Arad. The pipeline would cross 11 protected sites, two national parks, three natural reserves, and 57 watercourses, namely major rivers such as: Jiu, Coșuștea, Cerna, Belareca, Timiș, Bega, and Mureș, as well as their tributaries. The terrain is rockier in Romania and mainly composed of limestone. This section is long. Polish gas company PGNiG was studying the possibility of building a link from the Nabucco gas pipeline to Poland. Technical features The Nabucco-West was to be exempt from regulated third party access, including tariff regulation, for 25 years. Its proposal stated a capacity of per year. This capacity will be scaled up to to compensate for an anticipated increase in demand. Nabucco West would offer 50% of its transport capacity to third parties outside of the shareholders. Construction The Nabucco project was included in the EU Trans-European Energy Network programme and a feasibility study for the Nabucco pipeline had been performed under an EU project grant. The front end engineering and design (FEED) services of the pipeline, including the overall management of the local FEED contractors, the review of the technical feasibility study, route confirmation, preparation of the design basis, hydraulic studies, overall SCADA and telecommunications, GIS and preparation of tender packages for the next phase, was managed by UK-based consultancy Penspen. Starting from 14 December 2011, WorleyParsons was appointed as on owner's engineer. On 28 January 2013, it was announced that
