UKMTO Reports of Three Tankers Hit in Hormuz Reveal High-Risk Passage

On September 30, the most important information in the Strait of Hormuz was not the number of ships that passed, but that three messages from UK Maritime Trade Operations appeared late regarding incidents said to have occurred on September 29. Messages 144-26, 145-26, and 146-26 describe three separate hits on tankers, stating that the source is "verified," but they do not provide the reader with what is truly needed: the time of the incident, the name of the ship, a precise location, the type of projectile, the extent of the damage, or the identity of the perpetrator. These are not secondary details; they are the difference between a navigable passage and an experience of crossing under fire.

What Has Been Confirmed and What Remains Unresolved

According to gCaptain, UKMTO classified the three cases as attacks. The first mentions a crude oil tanker hit on its port side by an unknown projectile, the second refers to a tanker entering the strait that was struck by an unknown projectile, while the third simply states that a tanker was hit. The times of the three incidents are recorded as "pending confirmation." UKMTO did not report any casualties, injuries, pollution, or the stoppage of any vessel, nor did it name the entity that fired the projectiles.

This distinction is crucial because coverage discussing four ships within 24 hours conflates three late notifications from September 29 with a separate incident reported on September 28. In the earlier incident, UKMTO stated that a ship was hit by a suspected projectile, and a fire broke out, but the crew was safe and the ship continued sailing. The classification of that initial report was "suspicious activity," not an attack. Therefore, there is currently no professional basis to claim that four ships were struck at the same time or in a unified wave.

Maritime sources are circulating the names Mersin Prosperity and Sinbad, both crude oil tankers flying the Liberian flag; the former is a VLCC of approximately 299,319 deadweight tons operated by ADNOC according to tracking published by Maritime Executive, while the latter is about 115,949 deadweight tons and was last seen near Fujairah. However, UKMTO has not confirmed these names. Additionally, the claim that one of the ships is an LNG tanker is unverified; it appears in an unnamed maritime report, not in official notifications. The same caution applies to the suggestion that a tanker with a Chinese connection was among the cases: there is no official identification of ownership, cargo, or commercial beneficiary in the three notifications.

Delayed Reporting Becomes Part of the Risk

Practically speaking, the projectile is not the only danger. Delayed reporting increases the decision-making cost for the captain, the operating company, and the insurer. UKMTO is a voluntary system that relies on what is sent by masters, operators, and authorities, and thus news of an incident may take hours or days to arrive. When three reports emerge after the day has passed, a ship's operations room at sea cannot base its assessment solely on a map of public incidents. This explains the continued sailing with AIS turned off on a large number of tankers, but it does not make it safe; disappearing from tracking reduces commercial visibility and does not mitigate the threat of projectiles.

Maritime Executive reported from Fars News Agency that warning shots were fired near Qeshm Island against ships that "violated" traffic rules, while a spokesperson for the Revolutionary Guard stated that ships crossing without permission could be targeted or hit mines. UKMTO notifications do not confirm this narrative nor attribute the attacks to Iran. It is erroneous to jump from political threat to attributing technical aspects of the incident without images of damage, analysis of remnants, or official testimony from the flag state or operator.

Crossing Resumes but Under War Conditions

The numbers appear contradictory only if read without context. Data from Windward, as reported by Maritime Executive, indicates 17 apparent crossings on AIS on September 29 and 16 the day before, and 55 apparent crossings between September 16 and 23, with the actual number likely being higher. Kpler states that September flows, excluding Iran, returned to at least 16.5 million barrels per day, and that more than 70 percent of the crude passing in August changed its vessel at sea. This is not a return to normal operations; it is an alternative transport network relying on ship-to-ship transfers, the southern route, and reduced electronic visibility.

Additionally, about 40 percent of crude, according to Kpler's estimate, is now leaving without passing through Hormuz, compared to about 17 percent before the war, with greater use of Saudi and Emirati pipelines. Limited loadings from Yanbu have resumed after the September 10 attack, but their pace remains below pre-attack levels. Therefore, the rise in barrels does not eliminate the pressure on fuel, products, and LNG tankers; this market does not always have the same flexibility as crude in changing vessels, routes, or ports.

Testing for Escort and Insurance, Not an Announcement of Reopening

The presence of U.S. air and naval support in the southern corridor under CENTCOM may deter a large-scale attack, but it does not guarantee that every commercial vessel will receive early warning or protection at the moment of crossing. Naval capability is not just a piece of equipment. It is a triangle of capability: immediate information, clear command, and joint action between warships and commercial vessels. Late notifications reveal the information side, which is the weakest here. Purchasing a more expensive war policy or arranging for an escort does not fix this flaw alone.

For insurers, the known facts so far mean pricing individual risk, not a judgment that the corridor is completely closed. However, every unassigned hit and every unconfirmed name gives an underwriter reason to raise risk premiums or demand stricter operating conditions. For oil markets, the resumption of flows limits the immediate supply shock, while a single hit on oil, fuel, or LNG keeps the potential for a price spike alive due to travel time, cargo diversion, and risk costs, not just due to a lack of barrels.

Negotiations Under Field Pressure

The revelation of the incidents coincided with maritime reports of stalled U.S.-Iranian ceasefire talks. There is no proven link between the three notifications and the negotiations, but their timing clarifies the logic of pressure: keeping the strait passable enough not to lose economic leverage, and dangerous enough not to make passage seem truly cost-free. In my view, talking about Iran having "lost" the Hormuz card is premature; the card has shifted from the ability to close it entirely to the ability to impose selective uncertainty. This is less efficient militarily, but it may be more disruptive to insurance and trade.

The outcome is neither a blockade nor an opening. It is a high-risk trial crossing, where each ship owner tests the limits of deterrence day by day. If UKMTO or the flag states do not publish additional temporal and technical details, the high traffic numbers will remain evidence of an acceptance of escalating risk, not evidence of restored maritime security.
