Background
Iran's Ports and Maritime Organisation (PMO) came to renewed international attention in April 2026 when the IRGC Navy's 24-hour reopening of the Strait of Hormuz allowed only one vessel, the cruise ship Celestyal Discovery, to complete a transit. The PMO nominally administers Iran's commercial ports and coast guard functions, but operational control of the Strait has in practice rested with the IRGC Navy throughout the 2026 conflict.
Founded in 1964 and subordinate to Iran's Ministry of Roads and Urban Development, the PMO manages nine Major ports including Bandar Abbas, Shahid Rajaee, and Imam Khomeini. It issues vessel transit permissions and coordinates with the Islamic Republic of Iran Shipping Lines. During peacetime, around 21 million barrels of oil pass through Hormuz daily, with PMO oversight of the Iranian-side traffic.
The PMO's civil authority has been effectively bypassed since February 2026, when the IRGC imposed military control over Hormuz transits. The 17 April announcement of a 'complete opening' was attributed to Iran's joint military command, not the PMO, and the reimposition of restrictions within 24 hours confirmed where operational authority lies.
