All measured impacts were minor, locally confined and short-term only, according to the Nord Stream report

The findings show that the construction of the two 1,224 kilometre offshore pipelines through the Baltic Sea had only minor and short-term impacts on the environment, says Nord Stream.

From planning to completion of the project, Nord Stream invested over 100 million euros into environmental studies, planning and route design.

More than 40 million euros of the overall investment were devoted exclusively to the environmental monitoring system.

During construction, 22 companies were contracted to analyse 16 scientific subjects at about 1,000 sampling locations along the route from 2010 to 2012. The geophysical surveys covered roughly 40,000 line kilometres. After construction, data associated with the reinstatement and recovery of the Baltic Sea were also recorded and analysed.

According to Nord Stream, the results prove that its environmental objectives to minimize the pipeline length, to avoid environmentally sensitive areas, and to keep restrictions on marine users to a minimum were successfully met. The findings of the analyses of the data show no unexpected environmental effects. All measured impacts were minor, locally confined and short-term only.

In order to continue this path and foster further scientific exploration, Nord Stream has made the data from its environmental monitoring and surveys available for researchers and others working on preserving and improving the Baltic Sea.

One year ago, all collected data was published on Nord Stream’s website in form of the Data and Information Fund – Nord Stream’s contribution to the HELCOM Baltic Sea Action Plan. The searchable data catalogue offers scientists access to comprehensive information on marine live and cultural heritage.
