Somewhere between twenty and thirty thousand seafarers are currently aboard roughly two to three thousand merchant vessels in and around the Persian Gulf, unable to complete voyages, unable to disembark at most regional ports, and in many cases unable to refuse orders to sail in a waterway where ships are now being fired on. That is not a historical statistic. It is today, 18 April 2026.
The International Maritime Organization has called for urgent measures to ensure continuous resupply of water, food, fuel, and medical support to stranded ships. UN News quotes one UN official stating that there is no precedent for civilian seafarers caught in a war zone of this kind since the Second World War. At least one treatable onboard death has been attributed to medical evacuation failure. According to reporting by NPR and The National, roughly a third of the appeals reaching UN coordination channels are from crew members asking to be repatriated, irrespective of contract or compensation.
The majority of trapped seafarers are Indian nationals, reflecting India’s position as one of the world’s largest suppliers of merchant crew. Filipinos, Syrians, Indonesians, and Ukrainians follow in descending order. Today, 18 April, the Islamic Revolutionary Guard Corps opened fire on commercial vessels in the strait, and two of the affected ships are flagged in India. That means the seafarers already caught in the strait’s institutional vacuum are now also in the line of fire, and a disproportionate share of those being fired on share nationality with the thousands of crew already stuck at anchor.
It is worth sitting with that for a moment. Roughly eleven thousand Indian nationals are aboard vessels currently stuck in a waterway where Iranian forces fired on two Indian flagged ships today. These are not separate stories. They are the same story viewed from different sides of the same hull.
What conditions on board actually look like
Drinking water is now the single most urgent operational issue. Merchant vessels carry fresh water inventory sized for a planned voyage, not for an indefinite period at anchor. Shuttle resupply from regional ports is intermittent at best. Port operations across the Gulf have been repeatedly suspended during the crisis. Iranian ports are under United States blockade. Some vessels, based on flag or cargo, are unwelcome at ports nominally open. The result is that ships with a week of water buffer in their original plan have now been riding at anchor for weeks.
Medical evacuation is the second issue. A sick crew member aboard a vessel transiting a functioning waterway can usually be transferred to a coast guard or medical craft within hours. In the current state, every evacuation depends on which coastal authority is willing to receive a given flag on a given day, and on whether helicopters or fast boats can safely approach an anchorage. Bloomberg has documented that the GPS jamming now endemic across the strait has further complicated medevac operations, because rescue vessels cannot reliably navigate to the anchored ship’s declared position.
The third issue has a longer time horizon but is already arriving. Crew contracts carry maximum duration limits under the Maritime Labour Convention, enforced by responsible flag states. Crew members are now overrunning those limits because there is no way to conduct a standard crew change at sea in the current environment. Legally, thousands of seafarers are now in a state that should not occur under international maritime labour law.
Why this happens structurally
The proximate cause of each failure is a specific operational gap. Water resupply fails because there is no coordinated mechanism for neutral vessels to bunker anchored ships across contested political boundaries. Medevac fails because there is no central traffic coordinator running helicopter lanes across disputed airspace. Crew change fails because there is no shoreside facility that all sides of the conflict accept as neutral.
What unites the three gaps is the absence of a neutral maritime authority. The Suez Canal Authority has standing protocols for water resupply, medical evacuation, and crew change during periods of regional tension. The Panama Canal Authority does the same. Both maintain pre negotiated agreements with multiple shoreside facilities and medical operators, precisely so that commercial vessels caught in adverse conditions have an institutional pathway to safety. Hormuz has no equivalent structure, and therefore no institutional pathway exists.
Every seafarer aboard a ship in the Gulf right now is living the difference between a chokepoint with a functioning authority and a chokepoint without one—and the difference is not abstract. It is measured in litres of drinking water per person, in hours to evacuation, in months past contract expiry.
What a functioning authority would do automatically
In an institutional framework modelled on Suez or Panama, the following would happen without any special intervention during a regional conflict.
Water and provision resupply. The authority would maintain an active registry of vessels in its jurisdiction and the current status of each. A ship reporting low water would receive scheduled resupply within forty eight hours from a standing resupply operator under contract. This is normal port state control, augmented by chokepoint authority coordination.
Medical evacuation. The authority would operate a medevac coordination cell, with helicopter and fast boat capacity staged in advance and rules of engagement established with regional air traffic control before any conflict began. A crew member needing evacuation would typically be off the vessel within six hours and into a hospital within twelve. This is how Suez and Panama routinely handle crew medical emergencies.
Crew change. The authority would maintain crew change facilities at multiple shoreside locations, with diplomatic immunity frameworks that survive periods of elevated tension. Crew contracts could continue to rotate under the standard MLC regime. No seafarer would be held beyond their contractual period, because no operational reason would prevent the rotation.
All of this is standard practice at the two existing chokepoint authorities. The reason it is not happening in Hormuz right now is not operational complexity. It is institutional absence.
What the Paris initiative should add
The Paris initiative convened by Emmanuel Macron and Keir Starmer on 17 April is focused on defensive escort mission planning. That is a reasonable operational priority for a first meeting. But if the Paris process matures into an actual operating authority, its charter should include crew welfare provisions as a first tier commitment, not as an afterthought several years into operations.
Specifically, a Paris derived mission charter should include:
- Standing water and provision resupply agreements with Omani and Emirati port authorities, drafted before the mission stands up rather than negotiated in response to individual incidents.
- A multinational medical evacuation coordination cell, with helicopter and fast boat assets based at Muscat and Fujairah and clear rules of engagement that survive political tension.
- Crew change facilities with diplomatic immunity protections at three or more shoreside locations across the southern coast, so that a single port disruption does not cascade into a regional crew welfare crisis.
- A daily public reporting mechanism on seafarer welfare, with the current number of stranded crew published as an accountable metric that a specific institution is responsible for reducing.
These are not luxurious provisions. They are standard in every functioning chokepoint authority that has ever existed. Adding them to a Paris derived mission charter is one of the faster and cheaper institutional moves available right now, and it would materially change the working lives of tens of thousands of seafarers.
The human face of the vacuum
The 20,000 seafarers in the Gulf today are not abstract. They have names, families waiting for a phone call at home in Kerala and in Cebu and in Odesa and in Jakarta, contracts that should have expired weeks ago, and in at least one recorded case, a colleague who died aboard ship because no one could reach him with the medical help he needed.
The institutional vacuum at Hormuz is not only a commercial inefficiency and an oil market stressor. It is also, very directly, a failure to protect working people who are where they are because an industry whose revenue depends on them asked them to be there. Any serious effort to build a Hormuz maritime authority has to treat their welfare as part of the core mandate, not as a humanitarian footnote on an otherwise commercial charter.
The Paris initiative will be judged, in the end, not by the tonnage of escort vessels it assembles but by whether, within twelve months, no seafarer in the Gulf has to wait weeks for drinking water because no institution was responsible for bringing it.
