Oman's Salalah port was engulfed in flames on March 12 after reported drone strikes on the oil storage facilities.
British maritime security firm Ambrey confirmed that the strikes targeted port infrastructure, but no merchant vessels were damaged.
Salalah has suspended operations at its container and general cargo terminals, while other Omani ports are working normally.
Oman moved all vessels out of its main oil export terminal at Mina Al Fahal, located outside the Strait of Hormuz, as a precautionary measure.
About a million barrels of Omani oil are exported daily from Mina Al Fahal.
The incident appears to be part of a broader pattern of Iranian strikes on Gulf energy facilities, carried out in retaliation for ongoing military action by the United States and Israel.
