A surge in mysterious explosions and suspected limpet mine attacks on commercial tankers has raised alarm across the Mediterranean. These incidents are marked by stealth and ambiguity, hinting at growing geopolitical risks. Maritime insurers like Skuld are urging industry stakeholders to reassess risk strategies, citing a clear evolution in maritime threats that demands stronger vigilance and forward-looking security planning.
One of the most recent attacks targeted the Vilamoura, a suezmax oil tanker flagged in the Marshall Islands and owned by TMS Tankers. The explosion occurred around 90 nautical miles off Libya’s coast shortly after loading crude from Zueitina Terminal. Fortunately, no injuries or pollution were reported, though the ship sustained serious structural damage and had to be towed to Greece. Maritime analysts believe the damage pattern suggests the use of an externally attached explosive device—consistent with limpet mines.
Dryad Global has observed a troubling trend of underwater attacks against oil tankers in 2025, including vessels like the Seajewel and Grace Ferrum. A common thread among the targeted ships includes recent calls at Libyan or Russian ports. While suspicions point toward coordinated efforts possibly involving state actors, no concrete evidence has emerged. Skuld recommends increased crew training, underwater inspections after high-risk port calls, and enhanced surveillance to counter the mounting threat.
