News & live signals
The real numbers behind the maritime news — port congestion, chokepoint transits and ETA accuracy, pulled live from AIS across 51 ports and 12 chokepoints. Observed, dated, sourced. We state the figure; we don't infer intent.
Briefs
At Singapore, half the ships we track are sitting at anchor: 69 of 142
A live snapshot of Port Flow's Singapore port view: 69 of the 142 vessels we're currently tracking there are at anchor — 49%. At the world's busiest transshipment and bunkering hub, that's a lot of steel waiting rather than working.
Read →We checked our ETA against the ship's own: 2.8 h vs 32.8 h
Across 371 closed voyages to Rotterdam over the last 30 days, Port Flow's predicted ETA was off by 2.8 hours on average. The crew-broadcast ETA those same ships transmit was off by 32.8.

Methodology: figures are from public AIS across 51 ports and 12 chokepoints. We also run AIS-gap (dark) and loitering detection, but raw counts conflate intentional gaps with coverage holes — so we treat those as leads to investigate, not headline numbers. Where coverage is thin (parts of the Med and the Gulf) we say so rather than overstate. See the methodology and accuracy benchmark.
