DUBAI, July 5 (Reuters) - The U.S. Navy said it had intervened to prevent Iran from seizing two commercial tankers in the Gulf of Oman on Wednesday, in the latest in a series of attacks on ships in the area since 2019.

In a statement, the U.S. Navy said that at 0100 local time (2100 GMT), an Iranian naval vessel had approached the Marshall Islands-flagged oil tanker TRF Moss in international waters in the Gulf of Oman.

"The Iranian vessel departed the scene when U.S. Navy guided-missile destroyer USS McFaul arrived on station," the statement said, adding that the Navy had deployed surveillance assets including maritime patrol aircraft.

The Navy said that around three hours later it received a distress call from Bahamas-flagged oil tanker Richmond Voyager while the ship was more than 20 miles (32 km) off the coast of Muscat, Oman, and transiting international waters.

"Another Iranian naval vessel had closed within one mile of Richmond Voyager while hailing the commercial tanker to stop," the Navy statement said, adding that the McFaul directed course towards the merchant ship at maximum speed.

"Prior to McFaul’s arrival on scene, Iranian personnel fired multiple, long bursts from both small arms and crew-served weapons," the Navy said.

"Richmond Voyager sustained no casualties or significant damage. However, several rounds hit the ship’s hull near crew living spaces. The Iranian navy vessel departed when McFaul arrived."

U.S. oil major Chevron (CVX.N) confirmed that it managed the Richmond Voyager, that crew onboard were safe and the vessel was operating normally.

The TRF Moss' manager is listed in public database Equasis as Singapore-based Navig8 Chemicals Asia, but Navig8 told Reuters it was not connected with the tanker. The vessel's manager could not be immediately located.
