Summary

The Norwegian Maritime Authority has upgraded its Strait of Hormuz advisory from a strong recommendation to a binding prohibition, effective immediately and until further notice. All Norwegian-flagged vessels are now prohibited from entering the Persian Gulf via the Strait of Hormuz due to a critical threat assessment indicating attacks are likely, ongoing military operations, and reports of civilian vessels coming under fire while attempting to exit the area. Companies with vessels already operating in the region retain responsibility for continuously assessing whether remaining or departing poses lower risk.

“This change means that, until further notice, no Norwegian-flagged vessel may enter the Persian Gulf via the Strait of Hormuz.”

Why this matters

Shipping companies operating Norwegian-flagged vessels should verify current vessel positions against the Strait of Hormuz exclusion zone and implement the prohibition immediately. Companies with vessels already in the Persian Gulf, Strait of Hormuz, or Gulf of Oman should conduct heightened security assessments, particularly given documented GPS/AIS spoofing and radar disruptions that may impair navigational safety. Any planned voyages into the affected area should be cancelled or rerouted.

What changed

The Norwegian Maritime Authority has enacted a binding prohibition replacing its prior advisory recommendation, formally barring all Norwegian-flagged vessels from entering the Strait of Hormuz. The directive cites a critical threat environment with likely attacks, GPS/AIS spoofing across the Arabian Gulf and Gulf of Oman, and communication/radar disruptions. Civilian vessels attempting to leave the area have been attacked. Companies operating vessels already in the region must independently assess whether staying or departing presents lower security risk.

What to do next

  1. No Norwegian-flagged vessel may enter the Persian Gulf via the Strait of Hormuz until further notice.

We do not believe any companies are planning voyages into this area in the near future. However, given the way the situation has developed, it is important to underline that we are now moving from a strong recommendation regarding traffic in the area to a prohibition on entering the Strait of Hormuz. For ships already inside the area, level 3 still applies,” says Director General of Shipping and Navigation Alf‑Tore Sørheim.

This change means that, until further notice, no Norwegian-flagged vessel may enter the Persian Gulf via the Strait of Hormuz. For vessels already operating in the area, companies will remain responsible for assessing the security situation should circumstances arise where leaving the area is considered safer than remaining. Military operations are ongoing in the region, and the threat level is assessed as critical, indicating that attacks are likely and that conditions remain highly hazardous for commercial shipping (ref. JMIC#00126).

There are continuing reports of extensive GPS/AIS spoofing in the Arabian Gulf, the Strait of Hormuz, and the Gulf of Oman. Sporadic disruptions affecting communications and radar systems have also been observed.

“In recent days, civilian vessels attempting to leave the area have come under attack. This is an unacceptable and serious assault on civilian shipping. We are in close dialogue with companies operating under the Norwegian flag that have vessels in the area. We understand that the situation has deteriorated further and that they are now likely facing increased insecurity,” Sørheim says.
