The crew change checklist for fleet managers and agencies

The crew change checklist for fleet managers and agencies

A crew change looks simple on paper — one person leaves, another joins — but it touches flights, visas, port agents, immigration, medicals and the ship’s schedule. The IMO has estimated that around 150,000 seafarers need to be changed over every month. This checklist covers the steps that most often go wrong.

Key takeaways

  • ✓Start with the documents: passport, visa, seafarer’s book, medical and certificates must all be valid for the whole contract.
  • ✓Book travel only after the port agent has confirmed the vessel’s arrival and the local entry rules.
  • ✓Send the joining crew a single travel plan: flights, hotel, agent contact and boarding instructions.
  • ✓Close the loop: handover notes, sign-off date, sea service record and wages for the leaving crew.

The checklist

A practical crew change checklist. Local rules for immigration and health differ by port — always confirm with the port agent.

The most common reasons a crew change fails

  • •A visa or passport that runs out during the contract
  • •Flights booked before the vessel’s arrival was confirmed
  • •The joining crew member does not know who to call on arrival
  • •A certificate or medical that expires a few weeks after joining
  • •No reliever planned, so the leaving crew member’s contract is extended

Plan the next relief at the same time

The cheapest crew change is the one you planned months ahead. When a crew member signs on, set the planned sign-off date and start looking for the reliever early — especially for ranks that are hard to fill.

Maritime Delivery’s Crew Manager does this for agencies and fleets: crew changes with flights, hotel, agent and a 7-point checklist, a travel plan you can send to linked crew, relief-due alerts and certificate expiry reminders.

Rules change and differ between flag states. Use this guide as a starting point and always confirm current requirements with the issuing body or flag administration before you book a course or accept a job.

Frequently asked questions

What documents does a seafarer need to join a ship?+

Typically a valid passport, a visa for the country of joining if required, a seafarer’s book or discharge book, a valid medical certificate, the STCW certificates for the rank and a signed Seafarer Employment Agreement. Requirements vary by flag state and port.

Who pays for a seafarer’s travel to join the ship?+

Under the Maritime Labour Convention, recruitment must be free for seafarers and repatriation at the end of the contract is the shipowner’s responsibility. In practice the shipowner or manager arranges and pays the travel; check the employment agreement.

How far in advance should a crew change be planned?+

As early as possible — ideally when the crew member signs on, by setting the planned sign-off date. Travel should only be booked once the port agent has confirmed the vessel’s arrival and the local rules.
