European trader Tintrade is the charterer behind the release of a Palmali Shipping tanker that had been under arrest in Denmark.
Turkey's Palmali said the Estonian-based group had fixed the 19,800-dwt Natig Aliyev (built 2002) for two years.
"A relevant contract on the occasion was signed between Palmali and Tintrade," it said in a statement.
The vessel will be crewed by seafarers from Azerbaijan.
