Work out port turnaround time instantly with clear inputs, formula shown and shareable results.
Turnaround time is everything from arrival at the pilot station to departure: waiting for a berth, berthing manoeuvres, cargo operations and clearance. Splitting out the cargo-working share shows how much of the port stay is genuinely productive, which is the standard port efficiency indicator.
Turnaround
Total = waiting + berthing + cargo operations + documentation
Marine results are planning estimates only. Verify against the vessel's approved stability booklet, loading manual, class society rules and applicable maritime regulations before loading or sailing.
At a congested port it can exceed cargo time, and it is usually the largest single lever on turnaround because it depends on berth planning rather than crane productivity.
Every extra hour in port must be recovered by steaming faster later, which costs fuel at roughly the cube of the speed increase.
