Estimates published by the International Monetary Fund's PortWatch, built from satellite and terrestrial AIS. They cover waters our own receivers do not reach yet. These are the IMF's figures, not Voydar's counts.

The IMF estimates 4 port calls in the 7 days and 18 in the 30 days to Sep 25, 2026. That is 157% more than the same 30 days a year earlier (7).

Container: 2
Tanker: 1
Dry bulk: 15
General cargo: 0
Ro-ro: 0

Estimated cargo loaded and discharged in those 30 days: 0.1 million tonnes.
