Bosphorus and Dardanelles Transit: What Shipowners Should Prepare
Transit through the Bosphorus and the Dardanelles is a timed operation in a narrow waterway, not a line drawn on a voyage plan. Gurmar Shipping coordinates the local side of that transit for owners and operators whose vessels are already trading to or from Turkish ports.
Why the straits are planned separately from the port call
A berth in İskenderun, Mersin or the Marmara ports and a straits passage are related, but they are not the same appointment. Traffic organisation, daylight, vessel dimensions and the documents the master carries all affect when a southbound or northbound transit can be requested. Treating the passage as an automatic consequence of the port ETA is how ships lose a day at the anchorage.
The agent’s job is to keep the owner informed of the local timing and of the information the transit formalities still need. Gurmar does that from İskenderun, alongside the port-agency work, so the same operational record covers both.
Particulars that change the transit window
Length, draft, air draft, cargo type and any deficiency already noted by the master should be in the first message. A vessel that is light and a vessel that is deep do not wait in the same way. If the ship is calling at a Turkish port before or after the passage, the port ETA and the transit request have to be read together, because a delayed cargo completion moves the ship in the traffic picture.
Owners should also name the person who can answer a document question outside office hours. A missing paper discovered in the evening is only useful if someone on the owner’s side can still respond.
What the agent coordinates locally
Local coordination covers the formalities, the communication with the parties involved in the passage, and the updates back to the operator. It does not replace the master’s responsibility for the navigation, and it does not create a transit slot that the traffic organisation has not given. The agent’s reports should say what has been requested, what has been confirmed, and what is still open.
When the vessel is also taking stores, crew or bunkers in a Turkish port, those jobs are sequenced around the transit rather than booked as if the ship had an unlimited stay. A launch that arrives after the vessel has been called for the passage helps nobody.
Reporting during the passage
Operators usually want fewer messages, not more. A useful update states the vessel’s position in the plan, any change to the expected transit, and whether a document or a service is still outstanding. Gurmar sends that kind of note so the chartering and technical desks can act without reconstructing the day from a chain of short emails.
If the ETA into the straits changes, the revision should reach the agent as soon as the master knows it. Local arrangements and the information given to the authorities are only as current as the last ETA they received.
After the vessel is clear
Once the passage is complete, the agent confirms the time used and any local cost that belongs in the disbursement account. If the same vessel has a port call before or after the transit, those costs stay on one file so the final account is not split across two unexplained invoices.
Documents that were collected for the passage are kept with the port-call record. Owners who need a copy for their own file can ask for it with the voyage reference rather than searching an old inbox.
How to request straits support
Email gurmar@gurmarshipping.com with the vessel name, IMO, dimensions, cargo, the direction of transit and the ETA you currently hold. Add the Turkish port call if there is one. Gurmar reviews the particulars and replies with the local information needed to plan the passage and, where a port call is included, with a PDA.
The straits reward early, complete information. They do not reward a request that arrives when the vessel is already at the anchorage and the documents are still being searched for on board.
Reading the port call and the passage together
Many vessels transiting the Turkish Straits are also loading, discharging or taking supplies in a Turkish port on the same voyage. The mistake is to brief one agent on the port and another, later, on the passage, with two ETAs that no longer match. Gurmar prefers a single instruction that states the port, the direction of transit and the order in which the ship will do them. If the cargo operation overruns, the transit request is updated from the same file, and the owner sees one explanation rather than two conflicting ones. Protective interests, such as an owner who wants the commercial operator’s arrangements checked, can be noted in that instruction. The agent then knows who must be copied and which decisions must be referred back before a cost is accepted. Weather, traffic density and the vessel’s own deficiency list remain outside anyone’s ability to promise. What can be promised is a clear account of what was requested locally and what was confirmed. Send that request early, with dimensions and documents identified, to gurmar@gurmarshipping.com. A complete brief is the difference between a passage that is waited for knowingly and a passage that is discovered to be unprepared when the ship is already in sight of the anchorage.
