Shipping companies are avoiding U.S.-military-guided Hormuz transits after attacks in Omani waters exposed the limits of escort confidence.
1. Hormuz Transit Refusal Becomes the Lead Operational Signal
• Shipping companies are avoiding the U.S.-military-guided transit scheme through the Strait of Hormuz after a wave of Iranian attacks on vessels raised crew-safety concerns.
• Seven maritime security and shipping industry sources said the attacks have created doubts over whether the U.S.-assisted passage scheme can safeguard commercial vessels.
• Five ships have been attacked in Omani waters since July 7, including three crude supertankers, one LNG tanker and one container ship.
• The traditional Traffic Separation Scheme through the middle of the Strait has been disrupted by mine risk, forcing vessels toward makeshift routes close to the Iranian or Omani coast.
• More than 100 vessels coordinated directly with the U.S. military over the past seven days, according to a U.S. defence official cited by Reuters, but transit volumes remain below pre-war levels.
2. Blockade-Eve Traffic Shows Dark-Transit and Route-Control Pressure
• Windward recorded 41 Hormuz transits on July 14 before the reimposed U.S. blockade on Iranian shipping took effect at 2000 UTC.
• The traffic split was 23 inbound and 18 outbound transits, with all inbound vessels using the Northern Corridor.
• Nine inbound vessels and one outbound vessel went fully dark, while the remainder stayed AIS-visible.
• 37 Iran-flagged tankers and cargo vessels over 100 metres as high-probability blockade-breaker risks before enforcement began.
• Imagery showed nine dark tankers converging on Bandar Abbas roughly 12 hours before enforcement, consistent with a rush to complete Iran-linked transits before the blockade deadline.

3. Sanctions, Insurance and Charterparty Exposure Widens
• OFAC expanded sanctions against Mohammad Hossein Shamkhani’s shipping and sanctions-evasion network on July 14.
• Treasury said the action covered more than 50 individuals, entities and vessels, bringing the total under Shamkhani patronage to more than 200 sanctioned persons, entities and vessels.
• The network is described by Treasury as a major force behind Iran’s oil exports, with activity extending into containerized shipping and commodities trading.
• Sea Lead Shipping entities, We Freight Shipping, Volta Shipping Services and multiple vessel-owning companies were included in the sanctions action.
• Voyage desks should now treat Iran-linked cargo, ownership, management, charterer, STS history, AIS behavior and port-call history as linked clearance, insurance and sanctions-screening triggers.
4. Luni Casualty Adds Bandar Abbas Safety and Salvage Layer
• Safety4Sea reported that the bulk carrier Luni split in two and partially sank off Bandar Abbas on July 14.
• All 23 crew members were rescued safely.
• The 32-year-old vessel was anchored in the northern section of the Strait of Hormuz when it reportedly suffered water ingress before breaking apart and partially submerging.
• Local reporting cited by Safety4Sea said Luni had allegedly sustained hull damage in a collision several days earlier, but the cause has not been officially confirmed.
• The casualty is not currently linked to military operations, but it adds anchorage, salvage, pollution-watch and port-approach risk near one of the most stressed maritime zones in the Gulf.
Strategic Summary & Actions Required
• Masters approaching Hormuz should not treat “open Strait” statements as voyage clearance. Confirm company authority, route option, naval-contact protocol, UKMTO/JMIC reporting and abort criteria before entering the approach.
• Ship managers should issue written transit authority covering crew-risk acceptance, communications discipline, AIS/GNSS logging, evidence preservation, emergency steering, damage control and post-incident reporting.
• Charterers and operators should review war-risk clauses, deviation authority, off-hire exposure, unsafe-port arguments, sanctions warranties, force majeure language and laycan consequences for Gulf-linked fixtures.
• Compliance teams should rescreen Iran-linked cargoes, ship managers, beneficial owners, charterers, STS histories, AIS gaps and port-call records against the expanded Shamkhani sanctions network.
• Vessels near Bandar Abbas should verify anchorage status, casualty position, salvage activity, pollution warnings and local port instructions after Luni partially sank in the northern Strait area.
