ShipTracker ingests AIS across the South China Sea, the Strait of Malacca, the Java Sea, and the Gulf of Thailand — where a third of global trade transits daily. This is a guided tour through our Southeast Asian coverage.
Southeast Asia's ports each play a distinct role in the supply chain. Singapore is a container-dominant transshipment hub; Tanjung Priok handles bulk and general cargo for Indonesia's vast archipelago; Port Klang leans toward palm oil tankers and feeder containers. This Sankey traces the last thirty days of port calls across the busiest Southeast Asian ports, grouped by the type of ship that called.
Circle size is the raw volume of port calls over the trailing thirty days; colour encodes the dominant cargo type. Click any port to see its breakdown on the right — a doughnut of ship types and the recent call history.
Watch how Southeast Asia's busiest ports trade positions month by month across our portwatch coverage window (from December 2025 onward). Singapore anchors the top, but the race for the remaining spots is where the seasonal signals show up.
Three ports that define the busiest shipping lane on Earth. Singapore transships, Port Klang exports, and Saigon imports — each serving a different economy. Here are the last thirty days, side by side.
