There are pipelines in the same sea going from Norway to Germany, but these pipes are nowhere near the location of the Nord Stream leaks and go through the straight between Copenhagen and Malmo. The Russian Navy has a port in the Baltic Sea and regularly sails through it. They know these waters as well as anybody. There is absolutely no way they can intend to blow up the Europipe between Norway and Germany, and accidentally blow up the Nord Stream near Bournholm Island.
