Demining Black Sea: Challenging the legacy of war for safer trade

Demining the most important water areas in the Black Sea—anchorages, approaches, and waterways—will take five to seven months. Currently, the crews of the ships that are to carry out this task are training with NATO in the North Sea, while ships carrying Ukrainian goods weave between mines.

Communication routes leading from Black Sea ports are crucial for Ukrainian trade. Before the outbreak of full-scale war, this route was responsible for almost 70 percent of all Ukrainian exports. It was even more important for the export of grains and oilseeds—up to 98 percent was exported by sea.

The war triggered by Russia caused a temporary transport collapse through this channel. This dealt a blow to the Ukrainian economy and was an attempt to eliminate Ukraine from the global food market. According to data from the World Food Programme, the lives of around 400 million people, mainly in Africa and the Middle East, were dependent on grain supplies from Ukraine. By excluding Kyiv from this trade, Moscow hoped to take over its markets.

On July 22, 2022, despite the ongoing war, Ukraine and Russia signed an agreement known as the "Black Sea Initiative," which allowed the export of Ukrainian grain. The agreement was extended, although the Kremlin threatened to break it several times, most recently in the summer of 2023.

The grain corridor allowed a limited resumption of ship traffic. However, this does not mean that navigation from Ukrainian ports is safe. That's because since the beginning of the war, the Russians have placed around 2,000 mines in the Black Sea. Most of them were seized in 2014 in Sevastopol. These are old, Soviet-era charges. Since they have Ukrainian markings, Russia had no scruples in accusing Ukraine of planting them.

In October 2023, a Turkish freighter hit a mine off the Romanian coast. A month later, a Liberian-flagged bulk carrier transporting wheat hit a mine. In December, a Panamanian ship was damaged, injuring four sailors.

Due to such incidents, voyages in the Black Sea are high-risk, and some insurers are raising rates for ship owners or even refusing to insure vessels.

The Ukrainians are already preparing for a future operation to clear the sea routes. They know that free navigation in territorial waters will still be difficult for many years.

"The so-called urgent demining stage should last several months. These are anchorages, approaches, and waterways. It will take 5-7 months," said Commander Dmytro Pleteńczuk, press officer of the Ukrainian Navy. "The main stage of searching and destroying mines, however, will take several years. Unfortunately, our grandchildren will probably find similar devices. For example, this month, three mines from World War II landed on the coast."

Ukraine will carry out the demining operation with at least five mine countermeasure vessels but wants to cooperate with other countries in the Black Sea basin. In January 2024, Bulgaria, Romania, and Turkey signed the MCM Black Sea memorandum, which established a group tasked with demining international waters in the western part of the Black Sea.

Mines are not just a Ukrainian problem. This year, the Turkish navy has already raised an alarm due to the discovery of mines even in the Bosphorus Strait. These were probably anchored mines held underwater by steel cables, but apparently, some of them broke free. Romanian fishermen also raised alarms about mines.

Ukraine began modernizing its fleet in 2018. As part of this effort, in 2021, Kyiv purchased Sandown-class minehunters from the British, and last year Alkmaar-class minehunters from the Belgians and Dutch. These ships are to replace the 266M project units, which the Russians seized during the annexation of Crimea. The first of the new ships hoisted the Ukrainian flag in 2023, and more are expected to do so next year.

The ships didn't arrive in Ukrainian ports before the outbreak of the war—perhaps it was a stroke of luck. Currently, Turkey is blocking warships from warring parties from passing through the Bosphorus per the provisions of the 1936 Montreux Convention.

For demining the Black Sea, Ukrainians currently have to rely on improvised solutions. They use CV90 boats donated by the West, as well as rigid-hulled inflatable boats equipped with sonars and underwater unmanned vehicles used for seeking and destroying sea mines.

In early July 2024, the mine countermeasure ships "Chernihiv" and "Cherkasy" participated in the "SeaBreeze" exercises held off the coast of Glasgow. These exercises marked the culmination of two years of training for Ukrainian personnel and ship crews, which, as Commander Pleteńczuk wrote, "enabled them to effectively plan, monitor, and carry out mine countermeasure activities in various scenarios."

The Ukrainians joined NATO's Standing Mine Countermeasures Group 1 (SNMCMG1), which currently consists of the German supply ship and command ship "Donau," and French and Estonian minehunters. The Estonian "Ugandi" is also a Sandown-class ship, which allowed the Ukrainians to compare procedures and skills acquired during the training.

"The crews of Ukrainian mine countermeasure ships and the staff demonstrated exemplary enthusiasm, performing all training tasks and exceeding all expectations. International maritime cooperation among Alliance members is crucial to these efforts, and I am confident that it will continue to develop in the future," said Rear Admiral Steve Banfield, co-chairman of the coalition for the development of Ukrainian naval forces, after the exercises concluded.

Currently, Ukrainians can use only a few ports. Ports like Mykolaiv and Kherson are still blocked. The Russians almost daily shell them, and the waterways remain mined. Therefore, clearing the routes leading to Odesa or Pivdennyi is crucial.

Until the Ukrainians can pass their minehunters through the Bosphorus, civilian ship captains must rely on luck, as drifting Russian mines are now floating across the central and western parts of the Black Sea.
