Yemen's maritime blockade on Saudi shipping has pushed the kingdom’s crude exports off the radar in the Red Sea, with tankers forced to turn off their tracking signals to avoid attack and every recent cargo loaded at Yanbu sailing "dark," Reuters reported on Wednesday.
Saudi export volumes can no longer be independently verified as a result of the increased invisibility, with ship-tracking firms issuing conflicting estimates of the same shipments, figures the International Energy Agency (IEA), OPEC, and traders use to gauge world supply and forecast the market.
via AFPThree firms tracking the same week beginning August 3 reached three different conclusions.
Vortexa measured a modest decline at Yanbu, to 2.38 million barrels per day (bpd) from 2.71 million, while Kpler reported a collapse to 1.78 million bpd from 4.04 million, and AXSMarine recorded a rise, to 850,000 bpd from about 420,000.
Vortexa analyst George Morris said no Yanbu cargo lifted last week had its Automatic Identification System (AIS) switched on.
"Last week Yanbu liftings were all conducted dark. We're not seeing any loadings with Automatic Identification System (AIS) on at the moment," he said.
Kpler analyst Nhway Khin Soe said about 70 percent of loadings along the Saudi west coast were dark in recent weeks, and that every Yanbu cargo loaded since 23 July involved a vessel without continuous AIS coverage.&nbs
