We are an Istanbul-based bunker trading company with over 30 years of experience.
We handle fuel oil, gas oil (MGO) and marine lubricant supply to vessels from our Istanbul office, covering offer, nomination, delivery coordination and post-delivery documents. The ports below are the ones we work at most often. Each port page explains how bunkering works there, which rules apply and what we need for a quote.
Bunker supply at Turkish ports
-
Istanbul
Our office is in this city. We supply vessels waiting at anchor on the Turkish Straits route between the Black Sea and the Mediterranean, and vessels calling at Marmara ports.
-
Izmit Bay
Türkiye's industrial coastline. Refinery, petrochemical, automotive and container terminals share one bay.
-
Aliağa
The Aegean's energy port. Two refineries and the jetties of Nemrut Bay in one area.
-
Mersin
Türkiye's gateway to the Eastern Mediterranean, where container, general cargo and bulk meet.
-
Iskenderun and Ceyhan
The bay where pipelines meet the sea. Crude tankers and steel cargoes share the same waters.
-
Çanakkale
The entrance from the Aegean to the Marmara, and the line where the Mediterranean ECA ends. This is where fuel plans change most.
-
Ambarlı
Türkiye's busiest container area, and close to our office.
-
Tekirdağ
The north shore of the Marmara, 125 km west of Istanbul. Deep water and heavy tonnage.
-
Gemlik
The bay where Bursa's industry meets the sea. Automotive, container and general cargo together.
-
Bandırma
A dry bulk and ro-ro port on the south coast of the Marmara.
-
Izmir
The Aegean's city port. Containers and cruise ships in one bay, separate from Aliağa's tankers.
-
Samsun
The Black Sea port with a rail link. Its operator lists fuel supply by road tanker on its own page.
Bunker supply at Mediterranean ports
-
Malta
In the middle of the Mediterranean, on the main route between Suez and Gibraltar. Its rules are written and detailed.
-
Piraeus
Greece's largest port, at the gate of the city from which a large share of the world fleet is managed.
-
Gibraltar
The Mediterranean's gate to the Atlantic. Fuel is usually delivered by barge to ships at anchor in the bay.
-
Port Said
The Mediterranean entrance of the Suez Canal. A stem has to fit the convoy clock.
-
Limassol
The ship management centre of the Eastern Mediterranean. A bunkering and crew change port close to the Suez route.
-
Genoa
One of Italy's largest commercial ports and the sea gateway of northern Italian industry.
-
Algeciras
More than a third of Spain's bunker volume, directly across from Gibraltar.
-
Barcelona
A cruise and LNG port, with its own rule on the fuel used at berth.
Bunker supply at global hubs
-
Singapore
One of the world's largest bunker ports. A meter sets the quantity, and the rules are written and strict.
-
Fujairah
Outside the Strait of Hormuz, on the Gulf of Oman. Bunkering mostly takes place at the offshore anchorage.
-
Rotterdam
Europe's largest bunker port. Mass flow meters on bunker vessels have been mandatory since 2026.
-
Antwerp
Next door to Rotterdam, and reported to have overtaken it in sales in the first quarter of 2026.
-
Constanța
The large EU port on the Black Sea. The first question here is insurance, not fuel.

How bunkering works at a port
The order is the same at every port. Details are on each port page.
Enquiry
Vessel name, IMO number, port, ETA, grades and quantities. State whether it is at berth or at anchor. Give the grade with category, sulphur and ISO 8217 edition.
Confirmation and nomination
Once price and date are agreed, the order is confirmed. Many contracts ask for notice before arrival, commonly at 72, 48 and 24 hours. The agent handles port permissions.
Delivery
By barge, truck or berth pipeline. Not every method exists at every port, and a ship at anchor is served by barge. The sample is drawn during delivery in front of ship and supplier representatives.
Delivery documents
The BDN stays on board for three years and the MARPOL sample for at least 12 months. Time limits for quantity and quality claims are set in the contract.
Which sulphur limit at which port
The Mediterranean ECA began on 1 May 2025 and ends at the southern mouth of the Dardanelles. A scrubber counts as an equivalent method, but washwater rules are local.

Bunker supply: common questions
What do I need to bunker at a port?
For a quote, the vessel name, IMO number, port, ETA, grades and quantities are enough. The agent handles port permissions, and details are on the port pages.
Is the Marmara inside the Mediterranean ECA?
No. The ECA ends at the southern mouth of the Dardanelles. 0.50% applies under way in the Marmara and the Straits, but Türkiye's own rule applies 0.10% at berth and at anchor over two hours.
Can a ship enter the Mediterranean on VLSFO?
Not without a scrubber. 0.50% VLSFO does not meet the 0.10% ECA limit.
Do you deliver physically?
We are a bunker trader. Offer, nomination, delivery coordination and paperwork come from us, the physical delivery from the supplier in port.
Your port is not listed? Write to us
We also quote for ports not listed here: we arrange bunkers at any port worldwide. For a quote we need the vessel name, IMO number, port, ETA, grades and quantities.
