Seafarer Deaths in Hormuz and the Black Sea: Supplier Work

Updated 8 November 2026

At least 25 seafarers have been killed in the Strait of Hormuz since the US-Iran war began on 28 February 2026, according to the IMO, as reported by Marine Insight (November 2026). The Black Sea is now deadlier still, with at least 40 seafarers killed across 570 attacked ships (Marine Insight, October 2026).

The two Hormuz figures differ by date and scope: the IMO's 25 is a cumulative toll from the war's start on 28 February, while Seatrade's 24 counts deaths eight months into the same conflict, as reported on 28 October (Seatrade Maritime News, October 2026). Neither is a final count.

For chandlers, bunker suppliers, port agents and repair yards, crew casualties are now part of the operating condition on Gulf and Black Sea port calls. This is what changed, and what to do before the next ETA (the estimated time a vessel is due to arrive).

What happened in the Gulf and the Black Sea

Attacks have intensified rather than settled. Seatrade reports 121 vessels attacked in the Iran war eight months in, with at least 34 confirmed attacks since 28 September alone.

The Black Sea has overtaken Hormuz as the deadliest waterway. Splash247 reports more than 570 vessels attacked there during 2026, with seafarer fatalities exceeding those recorded around the Strait of Hormuz (Splash247, October 2026).

Casualties are not confined to strike zones. The UAE National Guard rescued all 22 crew of a cargo ship that caught fire in the Gulf of Oman, all reported in stable condition (Marine Insight, November 2026).

Why this lands on the supplier's desk

A casualty or a near miss changes the port call itself, and the port call is where chandlers, agents, bunker suppliers and yards earn. Three effects repeat across the region.

• Short notice and re-routing. A vessel that diverts or waits at anchor needs stores, water and bunkers at a port it did not plan for. The PDA (the port disbursement account, the agent's statement of costs for a call) is rebuilt at short notice.
• Crew change pressure. Where crews are stuck or ships are held, repatriation and relief requests arrive with the agent, not the charterer.
• War-risk paperwork. Owners and DOC holders (the company holding a vessel's Document of Compliance under the ISM Code) want evidence of safe berths, medical support and local response before fixing a call.

Research on the chokepoint supports the operational reading. A 2026 paper in the International Journal of Research and Innovation in Social Science describes the Strait of Hormuz as the most strategically important maritime chokepoint in the global energy system and argues the 2026 crisis exposed new vulnerabilities, including environmental hazards and cyber dangers (IJRISS, 2026).

Network studies point the same way. A 2020 study in IEEE Access built a crude oil transport network from AIS data and found the network's topology significantly affects its resilience after a disturbance (IEEE Access, 2020). AIS (the Automatic Identification System, which broadcasts a ship's position and identity) is the same signal suppliers can read to see where calls are actually moving.

What each supplier type should do before the next call

SupplierConcrete action this month Port agentKeep a standing war-risk pack per Gulf and Black Sea port: berth status, nearest hospital, launch availability, and a pro-forma PDA for a diverted call. Ship chandlerQuote fresh provisions and bonded stores for vessels already at anchor, and confirm delivery windows against security holds rather than the original ETA. Bunker supplierCheck whether a stem is still fixed after a re-route; offer an alternative barge slot at the new load port before the buyer re-tenders. Repair yardPrepare for casualty and fire damage work, and confirm class and flag approval routes before quoting a docking slot.

Two of these follow from the same logic: the buyer is not shopping on price when a ship is held. The agent who can answer a safety question in one email wins the call. That is the same reasoning behind pricing Gulf port war risk before the ETA.

The due-diligence side nobody mentions in the casualty reports

Conflict zones also move ownership. The Russian owner of the tanker Bella 1, also known as Marinera, is challenging a US sale after the vessel reportedly reached Chattogram, Bangladesh, on 4 November under the name Era (The Maritime Executive, November 2026). A vessel that changes name and flag before a recycling call is a supplier's credit and sanctions question, not just a headline.

Treat every new enquiry from a held or reflagged vessel as unverified until you have checked the registered owner, the manager and the DOC holder. The checks to run before extending credit to a ship supply customer apply unchanged when the ship arrives under a new name.

Where the regional work is still growing

Security risk sits alongside steady infrastructure spend in the Gulf. CIMC and the Oman Investment Authority have established a cooperation covering port logistics, green energy and localised industrial development (Seatrade Maritime News, November 2026). Aker Solutions has won a multimillion-dollar assignment to extend the life of an oil field offshore Qatar that has produced since the mid-1960s (Offshore Energy, November 2026).

Both create repeat port calls for project cargo, offshore support vessels and supply runs, in ports where a supplier's safety credentials now form part of the pitch. The supplier checks that follow a rising maritime security risk are worth keeping current as those calls are fixed.

How VesselReach helps

VesselReach turns vessel movements at your target ports into named conversations, so a diverted or re-routed ship does not arrive as a surprise enquiry. VesselReach for port agents and other maritime service providers connects vessel intelligence, decision-maker discovery and outreach in one workflow.

• Vessel intelligence: see vessels near your ports and scheduled arrivals before the ETA, which means you can prepare a war-risk pack or stores quote while the call is still being planned.
• AI company targeting and decision-maker discovery: identify the owner, manager or DOC holder behind each vessel and the operations, fleet or procurement roles to approach, which means your safety and availability answers reach the person fixing the call.
• Email, WhatsApp and phone outreach with automated follow-ups: stage the approach and follow up when there is no reply, which means an agent or chandler covers more held vessels without more researchers.
