Maritime Transport

UNCTAD Maritime Transport data contains port call and performance statistics that provide an overview of ships’ characteristics and the time they spent in a country’s ports during a certain period. Together, the tables include statistics for up to 8 commercial markets, covering the number of port calls during the period, the median time the ships spend in the ports, as well as information about the average age and size, and the size of the largest ships that have called during the period.The aggregated figures are derived from the fusion of automatic identification system (AIS) information with port mapping intelligence by MarineTraffic (http://marinetraffic.com), covering ships of 1000 GT. Only arrivals have been considered to measure the total number of port calls. To produce any measurement, there must be at least 10 arrivals on a country level per commercial market made by at least 5 distinct vessels as segmented. Missing data could therefore hide small numbers of arrivals that are then also excluded from aggregates. Passenger ships and RO/RO ships are excluded from time at port calculations.

This collection includes only a subset of indicators from the source dataset.
