The Russian naval authorities had asked for a 100-ton capacity floating crane in Kerch Strait to rescue the commercial ships sunk in the storm, said Adrian Alexe, director of Constanta Maritime Rescue Center.
"We responded promptly, as usual in such a situation, and offered the Gigant crane of the Administration of Maritime Port Constanta," he said.
Several ships from Russia, Turkey, Ukraine, Georgia and Greece sank or ran aground in the severe storm that hit the Azov Sea basin on Sunday. At least three seamen were killed and five remained missing.
It was reported that a Russian tanker spilled about 2,000 tons of oil. Experts say that the pollution caused by the spills could linger for years.
