Legitimate oil shipments through the Bosphorus could be trickling to a halt after protection and indemnity clubs’ failure to comply with new requirements imposed by Turkish authorities on tankers crossing.

Since 1 December, ships carrying crude oil through the waterway must produce a letter by P&I providers stating explicitly that they are covered by valid insurance during their voyage.

The letter needs to include ships’ details, cargo and voyage details. Agents must submit it together with the Sailing Plan 1 report when the vessel arrives at the Turkish Straits.
