Turnaround time
Also called: Ship turnaround time, Vessel turnaround time · Topic: International Trade: Patterns, Ports and the WTO · NCERT: Beyond NCERT
Meaning
Turnaround time is the total time a ship spends at a port, from the moment it arrives to the moment it leaves. It covers waiting for a berth (a parking place for the ship at the dock), loading and unloading cargo, and the paperwork and checks done before the ship can sail. A shorter turnaround time means the port works faster. Ships spend less time sitting idle, shipping costs fall and the port can serve more ships each year. That is why it is one of the main measures of how efficient a port is.
Example
The average ship turnaround time at Indian ports fell from 96 hours in 2014 to 49.5 hours in 2025. This happened under Sagarmala, India's programme for port-led development. Better cranes, more digital paperwork and deeper berths helped ships get in and out faster.
Don't confuse with
- Dwell time: this measures how long cargo, such as a container, stays in the port before it leaves. Turnaround time measures how long the ship stays.
- Transit time: this is the time a ship takes to sail between two ports. Turnaround time counts only the time the ship spends inside one port.
