Cargo ship Arne observed dropping/towing anchor near critical subsea cables off Ireland.
Irish security personnel observed the cargo vessel Arne towing or dropping its anchor near critical subsea infrastructure off Ireland’s west coast after it had loaded alumina at Aughinish in County Limerick and departed for Russia. The ship was reportedly under surveillance by the Irish Defence Forces and Coast Guard, and an Air Corps C295 maritime patrol aircraft was used to monitor its movements. According to the reporting, the incident occurred close to the AEC-1 cable, which carries important transatlantic data traffic between Ireland and the United States. That geographic proximity gives the episode clear relevance for a hybrid-threat tracker focused on risks to critical infrastructure. A month later, on 22 February 2025, German federal police and a Danish military ship intercepted the vessel near the Kiel Canal and escorted it to the Bay of Kiel for inspection. European security sources told the newspaper that the vessel was missing its port-side anchor and much of its anchor cable when inspected. The same report says the ship had also been moving unusually slowly near the C-Lion subsea cable linking Germany and Finland before that cable suffered minor damage, although German authorities were unable to link Arne directly to that damage. That is why the case is strongest as a maritime intrusion involving a suspicious commercial vessel, while any sabotage label should remain cautious and qualified. The ship’s operator and Rusal denied wrongdoing and said severe weather had caused the anchor loss, and the article states that German authorities did not establish intent. Even so, the vessel remained under ongoing surveillance by EU security services while in European waters, which shows that European authorities treated its behaviour as significant from a security perspective.
