Safety and mitigating environmental impact have always come first in Nord Stream 2's meticulous construction plan. Each step of building one of the world's longest offshore pipelines has been tailored to local conditions after extensive research and planning.
The twin pipeline stretches approximately 1,230 kilometres through the Baltic Sea from Russia to Germany, a route that largely runs parallel to the existing Nord Stream system. On both ends, landfall facilities have been constructed to suit local conditions, with the pipeline laid along the seabed in between.
Nord Stream 2 passes through the waters of five Baltic Sea nations: Russia, Finland, Sweden, Denmark and Germany. Because each country has its own unique set of conditions, thorough preparation was key. Extensive seabed surveys defined the optimum route, while detailed engineering and logistics plans enabled an around-the-clock construction schedule.
Pipeline construction began in 2018. By the end of 2019, it was complete in Russian, Finnish and Swedish waters, with much of the work finished in German and Danish waters as well. Because Denmark was the last country to grant a permit for construction in its waters, most of the remaining work had to be done in that area.
However, pipelay was suspended in December 2019 due to the threat of US sanctions that targeted the project’s contractors and financial investors. The European Commission described these sanctions as a breach of international law, and we created solutions to ensure that pipelay eventually continued. In early September 2021, the last pipes were welded into the pipeline string and lowered onto the Baltic seabed in German waters.
Next, the required pre-commissioning activities will be carried out with the goal of putting the pipeline into operation before the end of 2021.
Each step of the way Nord Stream 2 has worked with the world’s leading suppliers, applying rigorous environmental, health, safety, and social standards to protect the sensitive Baltic Sea environment and the communities affected by the project. All works have been carried out in compliance with national permit conditions and monitored for potential environmental impacts.
