Ships Reject US Military-Guided Strait Of Hormuz Transits After Iranian Attacks Raise Security Concerns

Some shipping companies are avoiding a U.S. military-guided transit scheme through the Strait of Hormuz after a series of attacks on commercial vessels raised concerns over crew safety, according to seven maritime security and shipping industry sources.

The move comes despite U.S. efforts to keep ships moving through one of the world’s busiest shipping routes. Although the United States says the Strait of Hormuz remains open and commercial traffic is continuing, the recent attacks have made some shipowners reluctant to use the U.S.-guided route.

Since July 7, five vessels have been attacked in Omani waters, including three crude oil supertankers, one LNG tanker and one container ship, based on Reuters’ analysis of incident data from the U.N.’s shipping agency. It was not immediately clear whether all of the vessels were sailing under the U.S.-guided transit programme.

“The U.S. doesn’t seem to have any control over the situation,” one shipping source said, adding that the company had decided not to send its ships through the strait because of growing security risks and concerns for its crews.

For decades, commercial vessels used the Traffic Separation Scheme (TSS), an internationally recognised shipping lane established by the U.N.’s shipping agency in 1968, to pass through the middle of the Strait of Hormuz.

However, since the conflict with Iran began on February 28, Iranian forces have mined that area, forcing ships to use temporary routes closer to either the Iranian or Omani coast.

In June, Reuters reported that the U.S. military began helping commercial vessels transit the strait using aerial drones, water drones and helicopters.

The operation was aimed at keeping Gulf energy exports moving and helped facilitate the export of tens of millions of barrels of oil, reducing the impact of disruptions to global oil and gas supplies.

However, recent attacks have raised fresh concerns about the safety of the alternative route near Oman.

Iran’s Revolutionary Guards said on Tuesday they were responsible for attacks on two Emirati oil supertankers.

Torbjorn Solvedt, principal Middle East analyst at risk intelligence company Verisk Maplecroft, said Iran’s continued ability to target ships using the Omani route suggested the U.S.-backed transit plan may not provide enough confidence for commercial operators.

The White House said shipping through the Strait of Hormuz continues.

“The Strait of Hormuz is open, and oil is flowing. Iran is committing acts of international terrorism by shooting at peaceful commercial vessels, targeting and murdering innocent civilians, and the United States is responding forcefully,” White House spokeswoman Olivia Wales said.

A U.S. defence official, speaking on condition of anonymity, said more than 100 vessels had coordinated directly with the U.S. military to pass through the Strait of Hormuz during the past seven days.

More than 300 vessels also passed through the wider region during the same period, showing the operation was continuing even though traffic remained below pre-war levels.

Iran warned on Wednesday that it could disrupt more regional energy exports after the United States reimposed a naval blockade on Iranian ports. Both countries also carried out further strikes as tensions over the Strait of Hormuz continued.

Tehran has also signalled it could use its Houthi allies in Yemen to target the Bab el-Mandeb Strait, raising concerns over another major shipping route linking the Red Sea to global trade.

According to another shipping source, around nine Greek-operated LNG tankers that entered the Gulf through the Strait of Hormuz over the past week to load cargoes remain inside the Gulf because of the security situation.

Two more tankers have also been attacked in open waters outside the Strait of Hormuz since July 7.

U.S. President Donald Trump wrote on Truth Social on Tuesday that the Strait of Hormuz “is open to ALL Ship traffic except for Iran.” The United States also reimposed its blockade on Iran-linked shipping the same day.

Last week, the U.S. Navy-led Joint Maritime Information Center raised its threat level for shipping in the Strait of Hormuz to “severe” from “substantial” after attacks on three tankers.

In guidance issued after the U.S.-coordinated transit programme was launched, the U.S. Navy said it would try to warn vessels about threats but might not be able to provide real-time updates.

Five maritime security and shipping sources told Reuters that ship operators still lacked enough information about the risks of using the Omani route.

“They have stated that the Strait of Hormuz is ‘not closed’ and remains available to use,” one maritime security source said. “This is making operators nervous and uncertain. Whilst they all have to make their own risk assessments, this is clearly not safe, so why say it is open?”

Greek maritime security company Diaplous advised shipping companies on Tuesday to pause voyages through the area until Saturday because of the high threat level.

Another Greek maritime security company, MARISKS, also said there was currently “no assurance that transits through the Strait of Hormuz can be conducted with an acceptable level of safety.”
