Twelve days of tracking data across all 56 Jones Act tankers. Every chart below points to the same conclusion: this fleet is fully employed, every day, with no idle capacity.
May 22 – June 19, 2026 | 29 daily snapshots | 56 ships tracked
Ships underway, in port, and in drydock for each daily snapshot since tracking began. The fleet consistently cycles between active transit and port operations with no idle days observed.
The 56-ship fleet spans four vessel types, each serving distinct segments of the U.S. energy supply chain.
The fleet spans three size classes and four vessel types. Large crude carriers (Suezmax and Aframax) primarily move Alaska North Slope crude to West Coast refineries — with the exception of the Alaskan Explorer, which trades Gulf Coast crude to East Coast refineries. MR product tankers distribute refined products along all U.S. coasts, Alaska, Hawaii, and Puerto Rico.
Number of ships actively underway (speed >2 kts) per day. The range of 28–40 reflects the natural rhythm of a fully employed fleet cycling through port calls — not idleness.
