Twenty oil tankers wait to cross Istanbul’s Bosphorus Strait

One more tanker took to 20 on Friday the number of vessels waiting in the Black Sea to pass through Istanbul’s Bosphorus Strait on the way to the Mediterranean, the Tribeca shipping agency said, amid talks to disperse the build-up.

On Thursday, dismissing pressure from abroad over the lengthening queue, Turkey’s maritime authority said it would continue to keep out of its waters oil tankers that lacked the appropriate insurance letters, and it needed time for checks.

Eight tankers were also waiting for passage through the Dardanelles strait into the Mediterranean, down from nine a day earlier, Tribeca said, making a total of 28 tankers waiting for southbound passage.

It requires vessels to provide proof of insurance covering the duration of their transit through the Bosphorus strait, or when calling at Turkish ports.

Ankara’s directorate general for maritime affairs said it was unacceptable to pressure Turkey over what it said were ”routine” insurance checks.

It said it could remove tankers without proper documentation from its waters or require them to furnish new P&I insurance letters covering their journeys through its territory.
