What kind of roads were you driving on back in the day, urbanotter? Send me the directions!
That type of transfer is usually reserved for refueling military vessels traveling within a fleet.
Whenever ship-to-ship transfers occur, they happen under strictly controlled conditions—certainly not out in the middle of the ocean.
Any Captain who can't accurately calculate a ship's weight and draft isn't going to stay a Captain for long. You know as well as I do that Captains face heavy fines from their shipping companies if it's discovered they could have loaded an extra 100+ tons and still cleared the Suez Canal normally. If they mess that up a couple of times, their career is over.
Everything entering the Mississippi has to be discharged at the northernmost points near Baton Rouge; from there, only low-draft barges head further north. What do you mean "ocean-going vessels" in the Mississippi? Why do you think the largest oil storage facilities in the world are located there? Everything is unloaded there first, and then moved upstream via river barges.
Come on, stop being so critical.
I mean, which river is Baton Rouge on, the Danube or the Sava?
There are three or four oil terminals in Baton Rouge, and it takes about 8 to 12 hours to sail from the mouth of the Mississippi up to Baton Rouge, with a maximum allowable draft of about 12 meters.
For comparison, a vessel of about 200,000 tons usually has a draft of around 16 meters.
And yes, they do perform transfers in open water, sometimes 200 NM away from the coast. These types of transfers are quite frequent in the Gulf of Guinea and Nigeria, where a ship might load about 70% of its cargo and then top off while anchored out on the open ocean.
Loading cargo is standard procedure handled under the supervision of the First Officer, rather than the Captain, who is busy with other responsibilities.
I'm certain the Captain knows how to calculate the draft, too; after all, he had to grind through several years as a First Officer just to earn that rank.
Of course, this isn't done regularly—it’s reserved for special cases out in the Pacific, thousands of miles from shore. There’s simply no reason for it otherwise, as a commercial vessel is meant to transport cargo from point A to point B without playing games.
You don't need to keep lecturing me; my son has actually been a First Officer on a tanker with a capacity just under 200,000 tons and a 16m draft for several years now.
Just two or three months ago, they were performing a ship-to-ship transfer in the open Pacific off the coast of San Francisco because their draft was too deep for the specific terminal they were assigned to.
Besides, you can use AIS to track all vessel positions and see where the concentrations are. In Mali, you'll often see ships anchored full of cargo, just waiting to hear where their destination is once a broker manages to sell the oil they've loaded.
Most of the time, when they load up, they don't even know their exact discharge destination; they're just sent in one direction and given the final coordinates later.
Anyway, so you don't have to struggle with it, here is a link where you can see where the ships are located and what they're up to.

Now you can sleep soundly, knowing that somewhere out there, oil is being transferred from ship to ship in the middle of the open ocean.😁😁
