UKMTO, the UK Maritime Trade Operations, is a Royal Navy division that collects and shares security reports from commercial ships, mainly in the Gulf, the Strait of Hormuz and the wider Indian Ocean. Its reporting is voluntary: vessels and operators choose whether to tell UKMTO what happened, which means the picture it publishes can be incomplete.

That gap matters to ship chandlers, bunker suppliers, port agents and repair yards because the security picture shapes how owners and managers plan port calls in the Gulf. If attacks go unreported, suppliers quoting those calls are working from a thinner risk picture than they think.

## What UKMTO actually does

UKMTO is a division of the Royal Navy that acts as a reporting and information hub for merchant shipping. It issues advisories and incident reports, and it is one of the first bodies a master or operator contacts after a security incident in the Gulf or the Indian Ocean.

Its output is widely followed by owners, managers, charterers and insurers, and it feeds into voyage planning and war-risk decisions. For a supplier, UKMTO advisories are a public signal of where security risk is being reported in the waters around a port.

## How voluntary reporting works

Voluntary reporting means a vessel is not obliged to tell UKMTO that it was attacked, approached or harassed. In practice, a master or operator decides whether to report, and many incidents are handled privately with insurers, flag states or navies instead.

That design has a direct consequence: UKMTO's weekly assessments reflect what has been reported to it, not necessarily everything that happened. When reporting falls away, the published record thins out even as the underlying risk stays high.

## Why under-reporting is now a Gulf problem

In October 2026, UKMTO said most vessels attacked around the Strait of Hormuz were no longer reporting incidents directly. According to [Splash247](https://splash247.com/hormuz-attacks-overwhelm-ukmto/) (19 October 2026), the volume of attacks has left the centre struggling to keep track, and UKMTO admitted in its weekly assessment that it is struggling to report accurately.

The same week, [Seatrade Maritime News](https://www.seatrade-maritime.com/security/ukmto-struggling-to-accurately-report-hormuz-attacks) (18 October 2026) reported four attacks over a weekend and noted that a majority of attacked vessels refused to report to UKMTO. [gCaptain](https://gcaptain.com/fog-of-war-deepens-in-hormuz-as-ukmto-says-most-ship-attacks-go-unreported/) (16 October 2026) described conflicting traffic figures and competing claims of control making it harder to establish what is happening in Hormuz.

The volume is not small. [Seatrade Maritime News](https://www.seatrade-maritime.com/security/ukmto-issues-four-hormuz-attack-reports-iran-claims-adnoc-tanker-strike) (13 October 2026) reported at least 18 attacks on ships in the Strait of Hormuz since the start of October. [The Maritime Executive](https://maritime-executive.com/article/ukmto-reports-third-strike-in-a-day-on-a-tanker-in-the-mideast) (12 October 2026) recorded previously unreported attacks on tankers in the Strait of Hormuz, and [gCaptain](https://gcaptain.com/new-reports-reveal-five-more-ships-hit-near-hormuz/) (12 October 2026) reported five more commercial vessels struck, including a containership and four tankers.

## What under-reporting means for suppliers quoting Gulf port calls

A port call in the Gulf is a commercial opportunity and a risk decision at the same time. Owners and managers weigh security advisories, war-risk cover and crew safety before confirming a call, and the supplier's quote sits inside that decision.

- **Thinner risk picture.** If most incidents go unreported, published advisories understate the risk around a port, and a supplier may quote a call as routine when the operator sees it as elevated.
- **Faster changes in demand.** When owners reroute or delay calls, stores, bunkers and repair work move with them. Suppliers who read only the published record can be late to that shift.
- **More questions from buyers.** Procurement and technical superintendents increasingly ask suppliers about security arrangements, delivery windows and contingency plans for Gulf ports.
- **War-risk costs in the quote.** Risk pricing affects the whole port call, and suppliers who understand the reporting gap can price and plan more realistically. Our post on Hormuz attacks and vessel reporting covers the supplier response in more detail.

## How a supplier should use UKMTO reporting

Treat UKMTO output as one input, not the whole picture. Use it to sense where risk is being reported, then combine it with your own operational intelligence on vessel movements and customer behaviour.

1. Check UKMTO advisories for the waters around the ports you serve before quoting a Gulf call.
2. Cross-check with what owners and managers are actually doing: rerouted vessels, delayed arrivals and changed ETAs.
3. Ask the technical or purchasing superintendent directly about security expectations for the call.
4. Record what you learn so the next quote for the same port starts from a better base.

Port agents carry much of this coordination, which is why the reporting gap lands first on their desk. Our port agents solution page sets out how that work fits together.

## How VesselReach helps

VesselReach, built by CatalystIQ, turns vessel movements around your target ports into conversations with the people who decide on stores, bunkers and repairs. For Gulf suppliers working through a patchy security picture, that means acting on vessel signals rather than waiting for published reports.

- **Vessel intelligence: VesselReach shows vessels near your selected ports and expected arrivals, which means you can reach decision-makers before the vessel arrives rather than after.
Decision-maker discovery:** VesselReach identifies operations, technical, procurement and chartering contacts behind each vessel, which means your security questions reach the person who owns the port call.
- **Multichannel outreach and follow-ups:** VesselReach runs staged email, WhatsApp and phone outreach with automated follow-ups, which means a Gulf quote stays in front of the buyer while the call is still being planned.

Book a VesselReach demo to see how vessel arrivals at your ports become qualified sales conversations.

## Frequently asked questions

### What does UKMTO stand for and what does it do?

UKMTO stands for UK Maritime Trade Operations, a Royal Navy division that collects and shares security reports from commercial shipping, mainly in the Gulf, the Strait of Hormuz and the Indian Ocean. It issues advisories and incident reports that owners, managers and insurers follow. ([Splash247](https://splash247.com/hormuz-attacks-overwhelm-ukmto/))

### Is reporting to UKMTO mandatory for ships?

No. Reporting to UKMTO is voluntary, so a master or operator decides whether to report an attack, approach or harassment. In practice many incidents are handled privately with insurers, flag states or navies, which is why UKMTO's published picture can be incomplete. ([Seatrade Maritime News](https://www.seatrade-maritime.com/security/ukmto-struggling-to-accurately-report-hormuz-attacks))

### Why are so many Hormuz attacks going unreported in 2026?

According to Splash247 (October 2026), the volume of attacks around the Strait of Hormuz has left UKMTO struggling to keep track, with most targeted vessels no longer reporting incidents directly. Seatrade Maritime News reported that a majority of attacked vessels refused to report. ([Splash247](https://splash247.com/hormuz-attacks-overwhelm-ukmto/))

### How should a ship chandler or bunker supplier use UKMTO reports?

Treat UKMTO advisories as one input for Gulf port calls, then cross-check with actual vessel behaviour such as rerouted ships and changed ETAs. Ask the technical or purchasing superintendent directly about security expectations, and record what you learn for the next quote.

### Can a maritime supplier act on the reporting gap without waiting for published reports?

Yes. VesselReach tracks vessels near your selected ports and expected arrivals, identifies the decision-makers behind each vessel, and runs staged email, WhatsApp and phone outreach with follow-ups, so you can reach the buyer while the port call is still being planned.

## More on this topic

UKMTO is the UK Maritime Trade Operations, a Royal Navy division that collects voluntary security reports from commercial ships, mainly around the Gulf and the Strait of Hormuz. Because reporting is voluntary, its picture can be incomplete, and in October 2026 UKMTO said most attacked vessels around Hormuz were no longer reporting directly. For Gulf port suppliers, that gap matters when quoting port calls: published advisories may understate risk, and owners may reroute or delay calls without it showing up quickly. Suppliers should use UKMTO advisories alongside vessel movement data and direct conversations with superintendents. VesselReach helps suppliers see vessels near their ports and reach the decision-makers behind each call.
