Crossings in the last 30 days
| Date and time | Direction | Lane | Est. cargo (M bbl) | Gap (h) |
|---|---|---|---|---|
| 13 Oct 2026, 00:39 UTC | Outbound out of the Gulf | Unidentified | 0.35 | 44.0 |
Outbound means from the Persian Gulf to the Gulf of Oman. The lane is the side of the strait the ship kept to: the Oman lane along Musandam or the Iran lane near the Iranian islands (see the map). Estimated cargo is deadweight × 95% × 7.33 barrels per tonne, for outbound oil tankers only. The gap is the hours between the last position on one side and the first on the other; a long gap means the ship was dark or out of coverage while it crossed.

Crossings are detected from AIS positions collected every 30 minutes; a ship with its transponder off can cross unseen, so treat the list as a lower bound (methodology). More: all tankers that crossed in the last 30 days · this month's statistics · ZEFYROS on MarineTraffic
