Saudi Crude Tanker Goes Dark to Slip Through Bab el-Mandeb

At least one oil tanker carrying Saudi crude oil has transited the Bab al-Mandeb Strait with its transponder switched off as risks to vessels in the Red Sea spiked this week after the Houthis announced a blockade on Saudi shipments and targeted vessels offshore Yemen.

The Merbabu tanker, owned by a Greek company and laden with Saudi crude oil, transited the Bab al-Mandeb Strait in the so-called dark mode, which many shippers and tanker operators used for months to move undetected to hostile targeting in the Strait of Hormuz.
