Russia has a programme to sabotage wind farms and communication cables in the North Sea , according to new allegations.

The Details come from a joint investigation by public broadcasters in Denmark, Norway, Sweden and Finland.

It says Russia has a fleet of vessels disguised as fishing trawlers and research vessels in the North Sea .

They carry underwater surveillance equipment and are mapping key sites for possible sabotage.

The Bbc understands that UK officials are aware of Russian vessels moving around UK waters as part of the programme.

The First of by DR in Denmark, NRK in Norway, SVT in Sweden and Yle in Finland.

A Danish counter-intelligence officer says the sabotage plans are being prepared in case of a full conflict with The West while The Head of Norwegian intelligence told the broadcasters the programme was considered highly important for Russia and controlled directly from Moscow.

The broadcasters say they have analysed intercepted Russian communications which indicate so-called ghost ships sailing in Nordic waters which have turned off The Transmitters so as not to reveal their locations.

The Report focuses on a Russian vessel called The Admiral Vladimirsky. Officially, this is an Expeditionary Oceanographic Ship, or underwater Research Vessel . But The Report alleges that it is in fact 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.

It says the vessel slows down when it approaches areas where there are wind farms and loiters in the area. It says it sailed for a month with its transmitter turned off.

When a reporter approached The Ship on a small boat, he was confronted by a masked individual carrying what appeared to be a military assault rifle.

The same ship was reportedly sighted off the Scottish coast Last Year . on 10 November and seen about 30 nautical Miles East of Lossiemouth, home to the RAF's Maritime Patrol Aircraft fleet before heading slowly west.

The Bbc understands that UK officials are aware of Russian intent to conduct what is known as undersea mapping, including using boats that move around in UK waters.

If there are specific threats against the UK these would be investigated, but sources declined to say what activity might have been looked at So Far .

In February, about activity that could indicate preparation for disruption or sabotage of marine infrastructure. The Head of the country's Military Intelligence said a Russian ship had been detected near a wind farm in the North Sea and was mapping out sites.

" We saw in recent months Russian actors tried to uncover how the energy system works in the North Sea . It is the First Time we have seen this, " General Jan Swillens said.

Reconnaissance of sensitive sites is not unusual and Western countries will likely be carrying out similar activity against Russia. The intention is likely to have a series of options available should a conflict escalate.

One option might be to damage communications or Take Down countries' power systems to cause chaos.

So Far The Evidence of actual sabotage rather than just Intelligence Gathering for the possibility is more limited.

The Report raises the possibility such vessels were linked to an incident south of Svalbard Last Year when an underwater data cable was cut.

The cable served The World largest commercial ground station for satellite communications. but have not officially accused anyone.

On 13 April this year, Norway expelled 15 Russian officials, accusing them of spying. It was the latest in a wave of expulsions across Europe since the February 2022 invasion of Ukraine.

In October Last Year police declared a major incident in the Shetland Islands after.

The Incident severely hampered communications with The Mainland and was blamed at The Time as having been likely caused by " fishing vessels".

There had been one clear and significant act of sabotage and that was the destruction last September of parts of the Nord Stream pipeline designed to carry gas from Russia to Europe.

At The Time , many accused Russia of being responsible but since then other reports have suggested other possibilities, including pro-Ukrainian actors, and investigations are ongoing.

Russian Military Intelligence , the GRU, has also been linked to both sabotage and poisonings. A GRU team linked to the poisoning of Sergei Skripal in Salisbury in 2018 with Novichok nerve agent was also linked to.
