A Greek-owned supertanker, the Kiku, docked at a terminal in Qatar on July 25. It was loaded with crude oil and later crossed the Strait of Hormuz. The tanker maintained a constant speed of 13 knots as it traveled through the Gulf.

On July 31, the Kiku disappeared from tracking after its AIS transponder was turned off. This device normally transmits the ship's identity and position.

Further details about the tanker's journey and disappearance are available from the source, including its last known location and the circumstances surrounding its disappearance.
