2 October 2017

Amsterdam, 2 October 2017

The Turkish Ministry of Environment and Urbanization announced the final approval of the Environmental Impact Assessment (EIA) for the offshore section of the TurkStream Offshore Gas Pipeline.

The EIA process

A thorough consultation process resulted in the final EIA. After publishing the draft EIA on 21 June, the Turkish government established a Review and Evaluation Commission (REC), consisting of 23 relevant institutions and authorities. On 4 July, the Ministry of Environment and Urbanization organized a meeting with the REC members in order to ask questions and provide feedback on the draft EIA. Subsequently, the REC members submitted their opinions on the draft EIA in writing. The EIA has been amended in line with these opinions. All REC members have now provided a positive opinion on the EIA to the Turkish Ministry of Environment and Urbanization. The approved EIA is available online.

The EIA consists of information on the potential environmental and social impacts of the offshore section of the TurkStream project. It also includes recommendations for the mitigation of the potential adverse impacts and enhancement of the beneficial ones.

In preparation of the EIA, field surveys were conducted to identify, assess and document potential environmental and social impacts of project activities. As part of the assessment, various Turkish stakeholders, including government experts, local community representatives and fishing groups, were consulted.

The EIA was prepared and submitted by ELC Group Inc. on behalf of South Stream Transport B.V., the project owner of the offshore section of the TurkStream Project.


TurkStream is the project for a transit-free export gas pipeline stretching across the Black Sea from Russia to Turkey and further to Turkey’s border with neighboring countries. The first string of the gas pipeline is intended for Turkish consumers, while the second string will deliver gas to southern and southeastern Europe. Each line will have the throughput capacity of 15.75 billion cubic meters of gas per year. On 10 October 2016, Russia and Turkey signed an Intergovernmental Agreement on the TurkStream project. South Stream Transport B.V., a wholly-owned subsidiary of Gazprom, is responsible for the construction of the gas pipeline’s offshore section. On 7 May, the Audacia vessel commenced construction of the TurkStream gas pipeline in the Russian nearshore.

Allseas Group is the world’s leading company in offshore pipe-laying and subsea construction. The company is focused on comprehensive project implementation, including design, material and equipment procurement, construction, and commissioning.

Pioneering Spirit is the largest construction vessel in the world, 477 m long and 124 m wide, designed for deep-water pipe-laying, installation and removal of large oil and gas offshore platforms.
