Vessel Turnaround Time

In ocean shipping, the time that is taken between the arrival of a vessel and its departure is referred to as the turnaround time. 


The calculation of average turnaround time (ATT) is easy to understand; it corresponds to the average difference between the date of departure and date of arrival of the vessel among all container vessels calling at a port (or country), usually within one month of navigation.


The vessel turnaround time is used to measure the efficiency of port operations.
