Construction in Germany

The pipeline will make landfall on the northern German coast near Greifswald. Construction along the 84-kilometre German section of the pipeline is divided into onshore and offshore sections.

In the onshore section, the pipeline inspection gauge (PIG) receiving station is being built to the west of the port of Lubmin. Preparatory work for the installation of the pipelines began in late January 2018, immediately after receiving the permit for the construction and operation of Nord Stream 2 for German territorial waters and the landfall area.

The PIG receiving station connects Nord Stream 2 with Gascade’s neighbouring natural gas receiving facility, and thus with the European pipeline network. The approximately six-hectare site will contain all the necessary control and regulation equipment for the safe operation of the twin pipeline.

Two 700-metre microtunnels will make the transition from the onshore to the underwater construction sections. The tunnels, which were built in the second quarter of 2018, start in front of the PIG receiving station, pass under the infrastructure to the north (railway track, road and supply lines) as well as coastal forest, dune and beach to end in the shallow water area approximately 350 metres beyond the beach.

In the summer of 2018 both pipelines will be drawn in via the tunnels to the PIG receiving station.Before this work can start, the trench area where both pipelines will be laid must be prepared. These preparations began in mid-May 2018. In total, an approximately 28-kilometre trench will be dug in German coastal waters for the two pipelines, as well as two parallel trenches approximately 21-kilometres long for each pipeline.

After the pipe has been laid, the trenches will be refilled and the top layer restored with the material previously removed. This accelerates regeneration and ensures that the effects of the intervention remains local and limited in time, with the lowest impact possible.

All work is overseen with extensive environmental monitoring to ensure that the predicted effects of construction outlined in the approved permit application documents are not exceeded. These effects include factors like water turbidity and noise, for example.

Rohrtransport

Nord Stream 2 setzt auf emissionsarme Transportmittel: Die zwölf Meter langen und zwölf Tonnen schweren Stahlrohre werden per Bahn vom Produktionswerk in Mülheim an der Ruhr zum Hafen von Mukran gebracht. Dort werden sie mit Beton ummantelt, dies verbessert die Stabilität auf dem Meeresgrund. Um rechtzeitige Lieferungen zu gewährleisten, nehmen seit Oktober 2016 jeden Tag zwei Züge der DB Cargo AG Fahrt auf. Jeweils elf Stunden benötigen die erfahrenen Zugführer, bis ihre Rohrladung Mukran in einwandfreiem Zustand erreicht.
