Case Description

The Blue Stream Project

Eni, as part of its commitment to conducting business in a responsible manner, adopts a proactive approach to environmental challenges and undertakes initiatives to mitigate the impact of its activities.

With respect to the climate change issue, natural gas (NG), because of its comparatively lower CO2 emission factor, is, among fossil fuels, the bridging source towards a less carbon-intensive energy system, as envisaged by the UN Kyoto Protocol.

Eni has always been strongly committed to expand the long-distance transportation of NG. In this connection, the Blue Stream project stands out for its record-breaking technological achievements: the 1,250 km Russia-Turkey gas pipeline includes two 380 km, undersea lines reaching the record depth of 2,150 meters in the Black Sea. Both sub-sea lines have already been laid down and at the end of this year the gas will start flowing in, with an initial capacity of 8 Bm3, which is expected to double by 2010.

The key for the realization of this project is the unique technology utilized for laying offshore pipelines and for related maintenance operations. Meanwhile, Eni is engaged in developing new technologies for high-pressure, long-distance pipelines to reduce transportation costs and bring the breakeven distance to about 5,000 km.The Blue Stream will help Turkey to meet its growing energy demand and to reduce the carbon intensity of the energy mix by replacing crude oil and coal: the initial reduction in CO2 emissions of about 8 Mt/year is expected to double by 2010, in proportion with increased gas imports.
