Hormuz Oil Flows Recover While Four Tankers Are Hit in Two Days
🔔 Subscribe to ShipUniverse Weekly →
Oil exports through and around the Strait of Hormuz have recovered sharply even as the security environment deteriorates again. Three Liberian-flagged tankers, Al Ruwais, Mersin Prosperity and Sinbad, were struck by unknown projectiles while transiting Hormuz on September 29, according to maritime intelligence service Marisks. The attacks followed a September 28 strike on Kuwaiti VLCC Al Funtas, which caused an onboard fire that was later extinguished with its crew reported safe. All four vessels were operating with AIS switched off or were reported through delayed security channels, underscoring how much current Hormuz traffic now takes place outside normal public tracking. At the same time, Kpler says non-Iranian Middle East Gulf crude exports reached at least 16.5 million barrels per day in September, matching the pre-war average, even though only about 60% of those barrels physically crossed Hormuz.
The Oil Is Coming Back. Normal Shipping Is Not.
Gulf producers have rebuilt export volumes through dark transits, shuttle tankers, pipelines and terminals outside Hormuz just as a new series of projectile strikes demonstrates that the physical waterway remains a high-risk operating environment.

Export volumes are recovering across the region, but vessel safety, transparency, tanker productivity and normal commercial routing remain impaired.
| Signal | Latest Position | What Changed | Shipping Mechanism | Current Constraint | Next Confirmation Point |
|---|---|---|---|---|---|
| Strait Security | 4 RECENT STRIKES Sep. 28–29 | Al Funtas was struck September 28. Al Ruwais, Mersin Prosperity and Sinbad were hit the following day. | At least several of the vessels were conducting dark transits with AIS disabled. | Source, weapon type and responsibility for the latest attacks have not been publicly established. | Additional attacks on dark-transit or shuttle tankers would indicate that AIS suppression alone is providing limited protection. |
| Non-Iranian Crude Exports | VOLUME RECOVERED 16.5M b/d | Kpler says September matched the pre-war average excluding Iran. | The volume now leaves through three systems rather than relying overwhelmingly on Hormuz. | Iran's roughly 1.7M-b/d pre-war exports remain largely absent under the U.S. blockade. | Whether October can sustain the September rate without additional tanker or infrastructure disruption. |
| Dark / Shuttle Crossings | CORE SYSTEM 70%+ Changed Ships | In August, more than 70% of crude crossing Hormuz subsequently changed tankers offshore. | VLCC shuttles cross the strait, transfer cargo near Fujairah or Sohar, then return for another load. | Every transfer requires additional tanker time, tug support, crews and transfer slots. | A rising share of direct India or China deliveries would reduce pressure on the shuttle network. |
| Qatar LNG | VISIBLE MOVEMENT RETURNS Multiple Cargoes | GasLog Skagen, Al Shamal, Mesaimeer, Al Ghashamiya, Al Samriya and Al Daayen have recently appeared outside the Gulf with Qatar-linked cargoes. | Some vessels are again making visible passages after August produced no visible Qatar-linked LNG transits in Kpler data. | Qatar still has no comparable pipeline export bypass for its LNG system. | Consecutive loaded Ras Laffan departures would provide stronger evidence of sustained LNG normalization. |
| Saudi Yanbu | BACK ONLINE ~2M b/d Loading | Saudi Arabia resumed tanker loadings after restarting its East-West Pipeline. | Petroline sends Saudi crude west to the Red Sea, avoiding Hormuz. | Pipeline throughput remains below the estimated pre-attack rate and full repairs may take weeks. | Kpler expects pipeline throughput to climb toward 3–4M b/d in the near term. |
| Fujairah Bunkering | PARTIAL RECOVERY 4.5M bbl Stocks | September residual fuel inventories rose from 3.9M barrels in August. | Saudi, Russian and STS-linked cargoes have helped rebuild supply outside Hormuz. | Inventories remain about half the roughly 9M-barrel pre-war average and VLSFO prompt supply remains tight. | Additional October VLSFO cargoes are expected to improve availability. |
| U.S.-Iran Talks | ACTIVE · NO DEAL Sequencing Dispute | Iran received U.S. feedback through Qatari mediators on its seven-day trust-building proposal. | The proposal includes reopening Hormuz and restoring normal maritime passage if agreed conditions are met. | Reuters says disagreement currently centers on the sequencing of the steps. | A signed arrangement specifying passage guarantees would represent a much stronger normalization signal than continued indirect talks. |

Separate total regional crude exports from the barrels that actually cross Hormuz, then estimate how much of that traffic is being handled through shuttle and offshore transfer operations.
