Black Sea: Winter storms cause increased threat from naval mines, through late February

Event

Winter storms are causing an increased threat from naval mines, through late February. Authorities in Ukraine have warned of the increased risk from naval mines to shipping and coastal communities. On Feb. 7, a mine exploded when it struck the coast at Agfa, Turkey, and on Feb. 13 another mine exploded near Batumi, Georgia. On Jan. 23, Bulgarian authorities neutralized two mines found off Tyulenovo and Cape Kochan. Further sightings of mines are likely in coming days.

Floating mines pose a direct hazard to shipping. Mines may also be washed up along the shore.

Context

Several hundred mines were deployed by Russian and Ukrainian forces at the start of the conflict in early 2022. These Soviet-era mines are typically moored to the sea bed, but can come loose as a result of storms and then drift with sea currents. This type of mine explodes on contact with a vessel or the coast. Authorities in Bulgaria, Georgia, Romania, Turkey, and Ukraine have neutralized around 40 mines since the start of the conflict.

Advice

Shipping operators and vessels must follow safety procedures. Sightings of mine-like objects should be reported to coastal authorities and shipping should remain well clear of the hazard. The forward area of ships should be kept clear of crew. Vessels should monitor local broadcasts for Navigational Warnings. Coastal communities should be aware of mines being washed ashore, and not approach any suspicious object.
