Milan-based contractor PetrolValves produced the most complex large-diameter valves it has ever made for the Nord Stream 2 Pipeline. Extensive collaboration and innovative new processes were required to execute the project.
Transshipment - from Kotka to Koverhar
After concrete coating, the pipes were shipped from Kotka to Koverhar, where they were stored until being laid. Pipe storage along the route allowed Nord Stream 2 to supply the materials needed in an efficient, timely and cost-effective manner, minimising impacts on the sensitive ecosystem of the Baltic Sea.
Dredging Activities in German Territorial Waters
To ensure stability in coastal areas, the Nord Stream 2 Pipeline was buried in the seabed. In Germany, this was done in the first section of the pipeline in the Bay of Greifswald. The preferred technique to do this is the pre-lay excavation of a trench.
Building the German Landfall
Ground conditions have proven favourable to using a special microtunneling technique that will minimise environmental impact at the Nord Stream 2 landfall in Germany. By taking construction underground, this method ensures that sensitive areas and existing infrastructure remain unaffected.
Nord Stream 2 at a Glance
Everything you need to know about the project to build one of the world’s longest offshore natural gas pipelines.
Telemetry Studies of Baltic Ringed Seals in the Gulf of Finland
Nord Stream 2 is supporting a program of telemetry studies of the Baltic ringed seal in the Gulf of Finland. The studies use GPS tags deployed on seals to collect information on their behaviour and movement patterns. Expanding scientific knowledge is vital for developing an effective strategy to preserve the population of this protected species. This documentary film explains the methodology and fieldwork conducted by an expert group for this project, which began in the summer of 2017.
Nord Stream 2 Logistics
A massive infrastructure project like the Nord Stream 2 Pipeline requires a precise and efficient plan. Learn about how our "green logistics" concept uses low-emissions transport to move pipes across the shortest possible distances and minimise environmental impact.
Before construction can begin, Nord Stream 2 must obtain permits according to the national legislation in each of the countries whose Exclusive Economic Zones and/or territorial waters the pipeline will cross. Learn more about how our permitting department engages the public and authorities in each country during the application process.
Nord Stream 2 and the Environment: Experts’ Opinion
Nord Stream 2 is committed to an open and transparent dialogue with stakeholders to ensure that decisions surrounding the project are based on proven expert opinion and clear scientific facts. Nord Stream 2 makes a point of communicating with the relevant parties: authorities, NGOs, the local community, scientific and research experts, institutes and other organisations. The objective is to disclose information about the project while also giving stakeholders the opportunity to provide their opinions about it. This video focuses on environmental experts’ opinion of the permitting process in Russia.
How Does Concrete Weight Coating Work?
A step-by-step overview of the concrete weight coating process, showing the materials and quality checks that are needed to prepare the pipe joints to be installed for the Nord Stream 2 pipeline.
Baltic Sea Discoveries with Nord Stream 2
With state of the art technology, Nord Stream 2 is surveying the Baltic Sea floor all the way from Russia to Germany. And with a route of over 1,230 kilometres to inspect for the planning and construction of the new natural gas pipeline, our expert survey team has discovered some fascinating objects.
A Walk Along the Route in Kurgalsky with Simon Bonnell
Based on extensive survey data we have been collecting since 2012, the overall conclusion is that Kurgalsky will offer the least environmental impact for landfall in Russia. Simon Bonnell, Head of Permitting for Nord Stream 2, talks us through the process.
