MARSEC Level 3 Advisory: GPS Spoofing Threats in Arabian Gulf and Gulf of Oman

The Norwegian Maritime Authority (NMA) has issued a MARSEC Level 3 security advisory for vessels operating in the Arabian Gulf, Persian Gulf, Strait of Hormuz, and Gulf of Oman. The advisory responds to increased military activity across the Middle East peninsula, documented cases of GPS spoofing targeting vessels in the Arabian Gulf, Red Sea, and widespread GNSS interference throughout the region. NMA recommends that vessel operators conduct comprehensive security assessments before entering Level 3 areas, update GNSS/GPS contingency procedures, and monitor threat intelligence from UKMTO and EUNAVFOR. MARSEC levels in the area may change on short notice.

Norway Prohibits Norwegian-Flagged Vessels from Strait of Hormuz

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.

20 Fall Incidents Recorded on Passenger Ships in Q1

The Norwegian Maritime Authority (NMA) recorded 20 fall incidents on passenger ships along the Norwegian coastline in January through March 2026, continuing an upward trend that began in 2020. Common causes identified by the NMA include breaches of procedures, inadequate anti-slip measures, unsuitable footwear, and work carried out under time pressure. The NMA emphasises the importance of systematic prevention, a strong safety culture, and compliance with procedures and routines to reverse this trend.
