The Egyptian navy is said to have discharged the Iranian crude cargo on a UAE-owned suezmax detained there since December.
AIS data shows the 163,000-dwt Sea Shark (built 1991) at anchorage south of Suez on 25 May.
It had been moved to the Ain Sukhna terminal last week, a source close to the crew told TradeWinds.
The source said the cargo was unloaded and "many items" stolen from the vessel.
