Part of Global Connect’s investment in building a new digital highway, Aurora. Baltic Offshore installed the submarine telecom cables between Sassnitz-Bornholm-Simrishamn and Bornholm-Öland-Gotland, as well as increased the capacity with a new subsea cable between Copenhagen and Malmö. Total length of installed submarine cables is over 460km where the majority of the route has been buried into the seabed by a jet trencher.
The Malmö-Copenhagen route is about 42 km where the cable has been buried into the seabed by a newly developed jet trencher in DK waters.
