Crew logistics
For offshore supply vessels and every other vessel calling Port-Gentil, the crew change is a movement Maingate Shipping plans end to end: immigration, airport, transfer, launch, hotel and the prompt report. Partner agent on the ground, Mombasa desk in charge.

Seafarers join and leave at Port-Gentil through Port-Gentil Airport, with connections through Libreville, and the movement is routine when the file is right. Maingate Shipping handles the immigration formalities, the airport, the transfer to the gangway and the hotel if the timings do not meet, and reports every movement to the owner with times and costs.
Port-Gentil is Mandji island on the Gabonese coast, the country's oil capital, and the island has no road link to the mainland, so crew, spares and provisions arrive by air or by sea and the plan allows for it; the crew plan is built with that in mind, so that a launch is not booked into a swell or a flight into a berth window that will not hold.
Crewing agencies, technical managers and owners under charter all place crew movements here; the desk acts for whoever instructs it and keeps that party's account separate.
Port-Gentil Airport is the door for crew at Port-Gentil. The desk's driver waits at arrivals with the vessel's name, walks the joiners through immigration on the pre-notification already filed, and brings them to the port gate or the launch. For leavers, the same driver collects them at the gangway and sees them through immigration and check-in.
Nobody buys a ticket until the vessel's schedule is firm; the desk holds options and rebooks when the ETA moves, which it usually does.

Immigration at Port-Gentil expects the crew list showing joiners and leavers, passports with adequate validity, seaman's books or seafarer identity documents, and the agent's letter of guarantee. Nationalities that need a visa are pre-notified or obtain it in advance where the rules require; the desk confirms the current position for each crew list rather than relying on a matrix that may be out of date.
Shore passes for crew going ashore during the call and gate passes for the agent's vehicle are issued through the port.

The last mile at Port-Gentil is the gangway or the launch. Alongside, the boarding officer walks the crew through the gate. At anchor, the launch goes out in daylight with the joiners and comes back with the leavers, and the desk confirms the ladder, the lee side and the timing with the master before it sails.
Off-port-limits crew changes for vessels in transit are done outside the port, with the vessel slowing to take the launch alongside and resuming passage within a couple of hours. Hotels near the port are used when flights land after the last launch.

Sick or injured crew are taken to hospital with an agent's representative, the owner and the P&I club are informed promptly, and repatriation with a medical escort is arranged when the doctor allows travel. Replacement seafarers are arranged in parallel from Kenya through our crewing desk so that the vessel does not sail short.
Every movement is reported to the owner with the times, the names and the costs, and the receipts follow in the DA.

The vessels that change crew at Port-Gentil are offshore supply vessels, crude tankers, general cargo ships and timber carriers, calling for crude oil outbound and the port's other trades, or passing on the routes that make Port-Gentil a convenient stop. Each type has its own rotation: cargo ships change a few officers and ratings per call, fishing and offshore vessels rotate crews in numbers, cruise ships rotate hotel staff on every call.
The island and the offshore fields, with Libreville reached by air and sea, which shapes how far the port is from the airport in practice and how much road time the plan must allow.
