The Islamic Revolutionary Guard Corps (IRGC) Navy has issued a map showing alternative shipping routes in the Strait of Hormuz to help vessels safely avoid naval mines.
According to Iranian media reports on April 9, 2026, the map clearly marks a large circular “area of danger” in the traditional traffic separation scheme. The IRGC Navy stated that all ships intending to transit the strait must coordinate directly with its units to comply with maritime safety rules and avoid possible collisions with sea mines.
Change in Recommended Routes
Tankers that previously passed closer to the Omani coast in the southern part of the strait are now being directed to take a more northerly route, closer to the Iranian mainland near Larak Island. The map provides separate paths for entering and exiting the Gulf to reduce risks.
Ongoing Caution Despite Ceasefire
This guidance comes amid the fragile two-week ceasefire between the US and Iran, under which Iran agreed to allow safe reopening of the Strait of Hormuz for international shipping. However, many shipping companies and owners remain hesitant, saying the situation is still unpredictable and they need clearer assurances before resuming normal transits.
The release of the map reflects Iran’s efforts to manage maritime traffic while maintaining control over the critical waterway that carries around 20% of global oil and gas flows. International observers continue to monitor developments closely as shipping activity in the region remains limited.
