Russian ships are suspected of sabotage in the North Sea during the Ukraine conflict.

The Danish counter-intelligence officer and the head of Norwegian intelligence have revealed that sabotage plans are being prepared for a full conflict with the West. The broadcasters have analysed intercepted Russian communications which indicate ghost ships sailing in Nordic waters. The report focuses on a Russian vessel called the Admiral Vladimirsky, which is an Expeditionary Oceanographic Ship, but is actually a Russian spy ship. The documentary uses an anonymous former UK Royal Navy expert to track the movements of the vessel in the vicinity of seven wind farms off the coast of the UK and the Netherlands on one mission.
