Rear Admiral Parach Rattanachaiyapan, spokesman for the Royal Thai Navy, said on March 14 that the Navy, through the Maritime Traffic Control Centre under the Naval Operations Centre, had issued a further maritime security alert dated March 13, 2026.
The notice was intended to warn Thai shipping operators and merchant vessels to increase vigilance while sailing in the Persian Gulf, the Gulf of Oman and the Strait of Hormuz, as tensions in the region show signs of intensifying.
According to the Navy’s maritime security assessment, there is a possibility that sea mines could be deployed in those waters, posing danger to commercial shipping and to one of the world’s most important sea lanes.

The Maritime Traffic and Vessel Control Centre has therefore issued additional guidance for Thai vessels and shipping operators.
Shipowners should assess risks and strengthen security measures in line with the ISPS Code and Best Management Practices;
closely monitor the situation and follow the advice of maritime safety authorities;
vessels should maintain radio communication on Maritime Band Channel 16 and be ready to respond to calls from maritime security agencies in the area;
and if any suspicious object or unusual incident is detected, it should be reported immediately to the centre, UKMTO and the relevant authorities.
The Navy has also issued guidance on how crews should respond if they encounter threats from sea mines, in order to reduce risks and improve safety while transiting the area.
The Royal Thai Navy urged shipping operators and Thai merchant vessels to follow maritime safety alerts and updates closely, and to comply strictly with the recommendations of relevant agencies in order to protect both crews and vessels. It added that it would continue to monitor and assess the situation and stand ready to issue further warnings as needed.
