MOSCOW, December 3. /TASS/. Turkey will lose up to $440 mln a year if the Black Sea straits are closed for transportation of Russian oil, head of Russian oil transportation company Transneft Nikolay Tokarev said on Thursday.

"What does the closure of the straits mean? That means that $110-115 mln tonnes of oil and oil products should go through some other outlets and won’t reach consumers via the straits. Turks also know how to count: in average transportation of one tonne of oil costs $3 not more than $4. Let’s multiply 110 million tonnes by $4 - that is what Turkey will lose," - he said.

Tokarev said that 60 million tonnes of 110 million tonnes are of Russian origin. This includes 25-27 million tonnes of oil and 35 million tonnes of oil products. The oil supplied by the Caspian Pipeline Consortium, Kazakh and Azeri oil account for the rest 40 million tonnes.

The head of Transneft stressed that Russia is able to redirect its oil flows.

"I come to the conclusion that there is no real threat for the transportation of Russian oil vi the straits," he said.
