Nord and South Stream offshore pipeline project

The purpose of the gas pipelines Nord Stream and South Stream is to satisfy 15% of Europe’s future energy demand.

Since 2007, Witteveen+Bos has been collaborating on the construction of the Nord Stream gas pipelines connecting Russia to Germany via the Baltic Sea. The second of the two parallel pipelines recently went into operation. In addition, we are a party to Nord Stream AG’s feasibility study into a further one or two pipelines from Russia to Germany.

Witteveen+Bos and Artelia are also collaborating on the offshore section of the South Stream project, a new gas pipeline linking Russia to Bulgaria. This highly complex project on the bottom of the Black Sea includes pipelines of some 900 kilometres long, with a maximum water depth of 2,000 metres.

Witteveen+Bos and Artelia have been awarded a sub-contract from INTECSEA, being the FEED (Front End Engineering & Design) for the impressive offshore section of the South Stream project. The main responsibility of the partners is providing support to the permit application and the Environmental Impact Assessment Processes. The South Stream project is aimed at strengthening the European energy security. It is a key project to ensure a direct connection between gas suppliers in Russia and consumers on the European continent. Running across the Black Sea, the South Stream offshore section will connect Russia to Bulgaria or Romania.
