Iran Strikes More Ship Engine Rooms in Ramp-Up of Hormuz Attacks

The main change is escalation. Attacks near the Strait of Hormuz have become more frequent and are causing more severe damage than earlier in the conflict. Shipping officials also report that Iran has recently used more missiles instead of drones. That matters because damaged ships remain unavailable for longer and create greater risks for crews and energy deliveries.

At least 23 incidents were logged in or near Hormuz during the first two weeks of October. At least five involved impacts to engine rooms. Engine-room strikes can start fires, destroy power systems, and stop propulsion. Officials said it remains unclear whether Iran is deliberately targeting engines. Infrared-guided missiles can seek hotter parts of a ship and often carry larger explosive payloads than drones.

Oil is still moving through the strait, but the threat is changing shipping economics. Ships may need months of repairs after serious damage, reducing the tanker fleet available to carry oil. That could push transport prices higher and discourage owners from entering the region.

A ship's engine room contains the main machinery that produces power and drives the vessel's propulsion system. It also supports essential systems needed for navigation, pumping, and onboard operations. Because so many functions depend on this space, damage there can disable a ship even when its hull remains afloat. That makes engine-room attacks especially disruptive.

The article says direct hits can cause fires and leave ships without power or propulsion. A missile or other weapon can damage engines, generators, fuel lines, control equipment, and electrical systems. Heat and fire may spread through the machinery space. Repairs can then require a vessel to leave service for months, rather than simply continuing with minor damage.

This is why recent engine-room impacts threaten energy transport. Every disabled tanker removes carrying capacity from an already constrained market. Owners may also become less willing to send ships through dangerous waters. The result can be fewer available vessels, longer delays, and higher costs for moving oil.

Naval groups and security consultants logged at least 23 incidents involving ships attacked in or near the Strait of Hormuz during the first two weeks of October. At least five of those incidents involved reported impacts to engine rooms. The figures measure reported incidents and damage, not necessarily every attack that occurred.

The engine-room number is especially important because those spaces are central to power and propulsion. A direct hit can trigger fire, destroy machinery, and leave a vessel unable to move. The article contrasts October with September, when the data recorded no attacks leading to engine damage. It also identified at least seven such attacks on non-Iranian vessels in previous months.

The early-October figures point to a more damaging phase of the conflict. Two recently hit vessels sank in one week, including a container ship struck in Hormuz. Continued attacks could keep ships under repair longer, reduce available tankers, and increase the cost of transporting energy.

More engine-room damage reduces tanker availability by taking vessels out of service. A ship with damaged engines, generators, or machinery may need to leave the trading route and undergo extensive repairs. During that period, it cannot load crude, deliver cargo, or earn freight revenue. The effective fleet becomes smaller even though the damaged ship still physically exists.

The article says direct hits can cause fires and eliminate power or propulsion. Such damage can keep ships unavailable for months and require costly repairs. If attacks continue, owners may also avoid Hormuz or demand higher prices to accept the risk. Both effects reduce the number of ships willing or able to carry oil from the region.

That tighter supply can raise freight rates. The article reports that hiring a supertanker was, for a few days, more expensive in some areas than sending a rocket into space. Analysts said every hit on a very large crude carrier is material where few owners are willing to enter.

The 1980s Tanker War was a period when Iraq and Iran attacked oil tankers in the Gulf. According to the article, both sides targeted engine rooms to disable vessels. Some attacks caused fires and explosions that sank ships. Damaged and sunken vessels remained in the northern Gulf for years, showing how attacks could leave a lasting physical and commercial burden.

The current pattern is similar because engine rooms are again being hit or damaged. Recent attacks have caused disabling fires, and at least two vessels sank in one week. A container ship struck in Hormuz was among them. The article also notes that the United States has targeted engine rooms when enforcing its blockade on Iranian ships.

The comparison does not establish that Iran is deliberately choosing engines today. Officials said it was difficult to know whether that was the intent. Still, the effect is similar: ships lose power or propulsion, crews face danger, and vessels may remain unavailable for long repairs.

If ships avoid Hormuz, producers can look for routes that bypass the strait. Established alternatives include pipelines to ports outside the danger area, overland rail or truck shipments, and other seaborne routes reached through different ports. Producers may also use storage and blend supplies from locations that do not depend on the strait. The article itself does not name specific alternative routes or methods.

The basic trade-off is capacity and cost. Pipelines and land transport can move oil without exposing tankers to attacks, but they may not handle the same volumes. Longer sea routes require more ships, fuel, and time. Rerouting can therefore increase freight costs, especially when engine-room damage is already removing tankers from service.

For now, flows continue through Hormuz. The United States estimated shipments at about 80% of normal levels, while Iraq said its exports were approaching prewar levels. If avoidance grows, alternative capacity may not fully replace the strait quickly, tightening energy supplies and transport markets.

The Strait of Hormuz matters because it is the maritime passage through which major Middle Eastern oil flows reach world markets. The article describes attacks there as a risk to regional energy flows and reports that oil shipments are still moving through the strait. Any disruption affects not only producers and buyers, but also the ships and crews needed to connect them.

Tankers generally load crude at export terminals near producing regions, enter the strait, sail toward destination ports, and unload for refiners or other buyers. Their engines and propulsion systems keep them moving between those points. A strike on an engine room can stop the vessel, while damage to the bridge or accommodation area can endanger navigation and crew.

Flows have continued, though estimates differ. Chris Wright put shipments at about 80% of normal levels, while Iraq said its exports were nearing prewar levels. More attacks could keep tankers out of service, raise freight prices, and make the global oil system less reliable.
