Three oil tankers struck by projectiles in Strait of Hormuz; AIS disabled
What happened
Three Liberian-flagged oil tankers—Al Ruwais, Mersin Prosperity, and Sinbad—were reportedly struck by unknown projectiles while transiting the Strait of Hormuz on Tuesday, according to shipping intelligence firm Marisks. All three vessels had disabled their automatic identification system (AIS) transponders prior to the incident. Two of the tankers had conducted ship-to-ship transfers off Oman, while Sinbad had loaded refined petroleum products in Saudi Arabia before the transit.
Context and assessment
The Strait of Hormuz remains one of the world's most strategically critical maritime chokepoints, with approximately one-third of global seaborne oil passing through its narrow channel. Incidents involving tankers in the waterway carry significant implications for energy markets and regional stability. The deliberate disabling of AIS transponders by all three vessels suggests an attempt to avoid detection, indicating awareness of heightened maritime risks in the region. Ship-to-ship transfers, a common practice for sanctions evasion or cargo redistribution, have become increasingly routine in the Persian Gulf, particularly involving vessels engaged in Iranian crude exports. The targeting of multiple tankers simultaneously, if confirmed, would represent an escalation in maritime incidents affecting commercial shipping in one of Asia's most vital trade routes.
