Bunkering at Istanbul
Black Sea gateway
Every vessel between the Mediterranean and the Black Sea passes the Turkish Straits, creating concentrated bunker demand in the Marmara anchorages off Istanbul.
Anchorage delivery
Bunkering is largely by barge at the Ambarli, Tuzla and Marmara anchorages, timed around Straits transit.
Frequently Asked Questions
Where does bunkering happen around Istanbul?
At the Marmara Sea anchorages (Ambarli, Tuzla and others) rather than mid-Bosphorus, coordinated with your Straits transit.
Is it a good Black Sea stop?
Yes — it is the natural fuel stop before or after a Black Sea voyage; we arrange barge timing to your schedule.
