On October 23, 2026, a Liberian flagged oil tanker was struck by a projectile during outbound transit through the Strait of Hormuz. The projectile hit near the engine room, disabling the main engine. A fire has been reported in the engine room where CO2 and boundary cooling is on-going. The Omani navy/coast guard has sent a boat to disembark the crew. The vessel’s management is arranging for the vessel to be towed to a safe port. All crew members are reported to be safe and in good health.
No pollution has been reported.

Liberian flagged vessels transiting the Arabian Gulf, Straits of Hormuz, Gulf of Oman and North Arabian Sea (affected area) are to operate at security level 3 and implement all protective measures in their Ship Security Plan. Vessels in the ports of the affected area are required to act upon the security level set by the Designated Authority at those ports.

Recommendations
Mariners are strongly advised to refer to the Joint Maritime Information Centre (JMIC) advisories: https://www.ukmto.org/partner-products/jmic-products for authoritative detail, including geographic limits, conditions of transit, and inspection and authorization requirements, including additional guidance to the threats, mitigations and considerations to transiting this area. Vessels operating in the Strait of Hormuz approaches, Gulf of Oman, and adjacent waters are advised to maintain heightened awareness, ensure maximum bridge readiness, and exercise appropriate caution with bridge-to-bridge VHF communications.
All owners, operators, and crews should remain cognizant of the elevated threat in the affected area and perform detailed, vessel-specific, voyage- specific and activity specific risk assessments for any operations or transit through the affected area.

All vesselsshould report to the UKMTO and register with the Maritime Security Centre for the Indian Ocean (MSCIO) in accordance with industry BMP (Best Management Practices) and take advice from the coalition forces operating in the area. Best Management Practices for Maritime Security (BMPMS) will continue to provide the necessary guidance for shipping to ensure threat and risk assessments are developed for every voyage to mitigate the risks presented by remaining security threats in the region. The shipping industry will continue to monitor and advise on maritime security threats to assist the safe transit of vessels and the seafarers.

UKMTO acts as the primary point of contact for merchant vessels and liaison with military forces in the region. Vessels are encouraged to register with UKMTO and report their positions (By email daily at 08.00 UTC) whilst operating in the area.
The MSCIO is the planning and coordination centre for the EU Naval Forces (EU NAVFOR). MSCIO encourages companies to register their ships’ movements before entering the Voluntary Reporting Area (VRA).

All vessels transiting the Arabian Gulf, Strait of Hormuz, Gulf of Oman and North Araiian Sea are also encouraged to report to the Information Fusion Centre – Indian Ocean Region (IFCIOR), this is a voluntary reporting measure that promotes cooperation, stability and communication with partner stakeholders in the region as well as aligns with the most recent measures published in BMP MS. Vessels with voyages through this area can use the Vessel’s Reporting Form at IFCIOR’s website.
