Lubmin – 50Hertz grid connection project Ostwind 1 remains on target. Work continues on the 90-kilometre long offshore section as well as on the 3-kilometre long land route.
So far, the first offshore cable has been installed over a distance of some 50 kilometres. In late November, the cable was successfully pulled into the offshore substation in the Wikinger wind farm (see photo). The necessary connecting works have been ongoing since then.
The laying activities for the remaining 40 kilometres will commence shortly. For instance, the immediate preparations at the landing point for the first submarine cable began today. In the next step, at the beginning of next week, the cable laybarge BODO CONSTRUCTOR will be positioned at approximately 400 metres off the shoreline at the bay side end of the landing point conduit. If the weather conditions remain stable, the offshore cable will be pulled through the installed conduit to its end position in the following days by means of a high-speed winch. Afterwards, the first cable will be laid up to cable kilometre 18.
Along the onshore route, all six conduit systems have now been completed. For this part of the project, a total of 48 horizontal tunnels were bored between the Bay of Greifswald and the Lubmin substation, the conduits or conduit bundles were pulled in, scraped, calibrated, gauged, pressure tested and connected to each other at 4 positions. The onshore pull in of the cable for the 3 cable systems will still start this year.
Even before the holidays, the laying works for the first section of the second offshore cable should start in front of Rügen island.
