Oil Tankers Turning Off Transponders – 10% of Regular Volume in Dark Fleet Made Hormuz Passage

TankerTrackers.com is one of the highest-quality public sources available right now. Kpler & Vortexa now note the trickle of dark or escorted transits. 14-16 Tankers passed through Hormuz Today.

Traffic is way down with normal ~150+ vessels per day has collapsed to low single digits or low teens (80-90% drop).
Tactics being used are turning off AIS during transit.

  1. I heard that the navigable channel for large tankers is only two miles wide?

    Should be relatively easy for Iran to mine?

    I am deeply impressed as to how far “intelligent” sea mines have become.

  2. I used to work with shipping. The strait of Hormuz is the nastiest bit of water. Its narrow, shallow and has poor visibility. Its possibly the origin of the idiom ‘Round the bend’.

    Its not just bombs and missiles that will close the straits. Each lumbering tanker needs to know exactly where it is, and where its neighbours are. If Iran are saturating the area with GPS and communication jammers, they can do that entirely passively. There are beacons all along the coast, like lighthouses. They will have been switched off too.

    One or two tankers might make it through at a time, but thats more to do with the straits being empty than sneaking passed Iranian speedboats.
