Oman's Maritime Security Centre issued a navigation warning on Saturday after spotting a floating object suspected to be a naval mine inside Omani territorial waters near the Strait of Hormuz. The object was reported west of the Inshore Traffic Zone, and the agency urged seafarers, fishermen, and commercial vessels to keep a safe distance and report any further sightings. Authorities have not yet confirmed the object is a mine or attributed it to any actor.
The alert lands amid months of escalating warnings from shipping organizations that mine threats remain one of the biggest obstacles to restoring confidence in the strategic waterway. A joint industry advisory issued earlier in May cautioned shipowners about floating mines, unexploded ordnance, and possible errant mines left in the water after clearance operations. The advisory stressed that neither side of the Strait can be presumed free of hazards and described an operating environment combining mines, drones, missile risks, electronic warfare, AIS spoofing, and severe congestion.
U.S. officials have flagged the same concern. Department of War Secretary Pete Hegseth identified mines in April as a central challenge to restoring normal commercial traffic through Hormuz and confirmed that U.S. mine countermeasure operations were underway, while declining to dismiss reports that clearing the Strait could take months. President Donald Trump has repeatedly said American naval forces are running expanded clearing operations and has ordered the military to destroy any vessel observed laying mines.
BIMCO Chief Safety and Security Officer Jakob Larsen has argued that mine clearance, not simply a ceasefire, will determine whether tanker traffic returns in force. Larsen said in April that the mine threat was of particular concern and that shipowners would likely require credible proof the waterway is safe before resuming anything close to normal volumes. Commercial throughput at Hormuz remains well below historical norms despite periodic political claims of improving conditions.
For shipping, Saturday's warning is a reminder that the Hormuz debate is no longer only about whether the waterway is open. The more consequential question is whether owners, insurers, and charterers can be convinced it is safe enough to send hulls and cargo through at scale.
