# Hormuz Attacks: What Bunkering Companies Face Now > Hormuz attacks are changing who orders Gulf bunkers. See what bunkering companies must check on buyer, credit and ETA before the next stem. URL: https://vesselreach.si/blog/hormuz-attacks-what-bunkering-companies-face-now | Published: 2026-11-08 | Industry news | Topic: Segment playbooks (bunkering) ## In short Bunkering companies in the Gulf now face a changed buyer. Gulf producers are assembling nearly 230 tankers while independent owners step back, and some sanctioned, Iran-linked tankers went dark over the Gulf of Oman. Before accepting a stem, confirm the DOC holder, screen the counterparty, price war risk into credit terms and watch expected arrivals, not just ships alongside. ## Key takeaways - Gulf oil producers are assembling a fleet of nearly 230 tankers as independent owners avoid the Strait of Hormuz, MarineLink reported on 29 October. - The IMO said at least 25 seafarers have been killed in the Strait of Hormuz since the US-Iran war began on 28 February 2026. - Confirm the DOC holder and technical manager before quoting, because the company ordering fuel is often not the registered owner. - Sanctioned, Iran-linked tankers went dark over the Gulf of Oman, so a clean AIS arrival at Fujairah may not be the hull it appears to be. - Hold barge slots loosely, because an ETA can slip by days when a convoy or clearance is withdrawn. ## At a glance - **What: What happened in the Strait of Hormuz in early November 2026?** Iran and the United States traded strikes on commercial vessels in and around the Strait of Hormuz over the weekend of 7-8 November 2026, and crews abandoned at least one tanker. ([Seatrade Maritime News](https://www.seatrade-maritime.com/security/crew-abandon-tanker-in-hormuz-us-strikes-bulker-in-gulf-of-oman)) - **Who: Who is affected by the attacks?** 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, with thousands still stuck in the Gulf.

([gCaptain](https://gcaptain.com/tanker-disabled-in-strait-of-hormuz-attack-another-vessel-reported-on-fire-in-persian-gulf/)) - **Why: Why are Gulf oil producers building their own tanker fleet?** Gulf oil producers are assembling a fleet of nearly 230 tankers to keep crude exports moving through Hormuz, because independent shipowners are reluctant to operate in the region. ([MarineLink](https://www.marinelink.com/news/gulf-oil-producers-build-tanker-fleet-544013)) - **How: How are sanctioned tankers avoiding detection?** Sanctioned, Iran-linked tankers went dark over the Gulf of Oman cable corridors as the IRGC threatened them, meaning they do not appear on a clean AIS track. ([Hellenic Shipping News](https://www.hellenicshippingnews.com/sanctioned-iran-linked-tankers-went-dark-over-gulf-of-oman-cables-as-the-irgc-threatened-them/)) Bunkering companies in the Gulf now face a different buyer mix after the November 2026 Hormuz attacks. Iran and the United States traded strikes on commercial vessels over the weekend of 7-8 November 2026, [Seatrade Maritime News reported](https://www.seatrade-maritime.com/security/crew-abandon-tanker-in-hormuz-us-strikes-bulker-in-gulf-of-oman). The commercial question is who is still ordering fuel, on whose hull and on what credit. ## What happened in the first week of November The IMO said at least 25 seafarers have been killed in the Strait of Hormuz since the US-Iran war began on 28 February 2026, [according to Marine Insight](https://www.marineinsight.com/imo-25-seafarers-killed-strait-of-hormuz-since-war-began/?utm_source=rss&utm_medium=rss&utm_campaign=imo-25-seafarers-killed-strait-of-hormuz-since-war-began). Crews abandoned at least one tanker in the strait during the weekend strikes. The pattern has been building since late October. A tanker was disabled by a projectile in the Strait of Hormuz and another vessel was reported on fire in the Persian Gulf, [gCaptain reported on 26 October](https://gcaptain.com/tanker-disabled-in-strait-of-hormuz-attack-another-vessel-reported-on-fire-in-persian-gulf/). Oman evacuated a tanker crew as Iran claimed a spate of new attacks, [The Maritime Executive reported on 30 October](https://maritime-executive.com/article/oman-evacuates-tanker-crew-as-iran-claims-spate-of-new-attacks). A Qatari LNG carrier with 25 crew was targeted near the strait on 30 October, hours after Iran had cleared its passage, [Marine Insight reported](https://www.marineinsight.com/pakistan-bound-lng-tanker-with-25-crew-attacked-near-hormuz-hours-after-iran-cleared-its-passage/?utm_source=rss&utm_medium=rss&utm_campaign=pakistan-bound-lng-tanker-with-25-crew-attacked-near-hormuz-hours-after-iran-cleared-its-passage). On 6 November a seafarer went missing after a missile-suspected attack on a Greek-operated product tanker deep inside the Arabian Gulf, [Splash247 reported](https://splash247.com/seafarer-missing-in-gulf-tanker-strike-as-iran-redraws-hormuz-blacklist/). A VLCC engine room was struck in Omani waters on 4 November, the fifth confirmed attack in three days, [Seatrade Maritime News reported](https://www.seatrade-maritime.com/security/vlcc-engine-room-struck-in-latest-hormuz-attack). ## The fleet is changing hands, not leaving Gulf oil producers are assembling a fleet of nearly 230 tankers to keep crude exports moving through Hormuz, because independent shipowners are reluctant to operate in the region, [MarineLink reported on 29 October](https://www.marinelink.com/news/gulf-oil-producers-build-tanker-fleet-544013). That is the commercial core for a bunker supplier. The volume of Gulf lifting has not disappeared. The ownership of the tonnage carrying it has moved towards producers, national fleets and operators willing to accept the risk. For a bunkering company, that changes the counterparty on the stem, not the number of stems. A second source of demand sits alongside it. Sanctioned, Iran-linked tankers went dark over the Gulf of Oman cable corridors as the IRGC threatened them, [Hellenic Shipping News reported](https://www.hellenicshippingnews.com/sanctioned-iran-linked-tankers-went-dark-over-gulf-of-oman-cables-as-the-irgc-threatened-them/). Dark tonnage still burns fuel, but it does not appear on a clean AIS track and often refuses to name its owner. ## Why position data stops being enough AIS (the Automatic Identification System, which broadcasts a ship's position and identity) is the basis of most bunker sales targeting. When vessels switch off or spoof their signals, the picture weakens. A 2026 paper in IEEE Security & Privacy examined location spoofing, identification manipulation and electronic interference around the Strait of Hormuz, [as its abstract states](https://doi.org/10.1109/msec.2026.3704691). A 2025 study in IJHESS described the strait as 55 to 95 kilometres wide and central to global energy trade, with recurring security disturbances compounding regional complexity, [according to its abstract](https://doi.org/10.55227/ijhess.v4i6.1351). For a bunker supplier, that means a vessel showing a clean arrival at Fujairah or Khor Fakkan may not be the hull or the company it appears to be. Verification has to happen before the nomination is accepted, not after the barge has sailed. ## What changes for suppliers Bunkering companies should treat every Gulf enquiry as a due-diligence event during this period, because the buyer behind the stem is now more likely to be a producer-owned fleet or a dark-fleet operator than an independent owner. A short checklist covers most of the exposure: - **Identify the buyer, not just the vessel.** Confirm the DOC holder (the company holding the Document of Compliance under the ISM Code) and the technical manager before quoting. The company that orders fuel is often not the registered owner. - **Screen the counterparty.** Check the vessel and company against sanctions lists and the blacklists Iran has been redrawing around Hormuz. Our guide to [sanctions lists to check before a port call](https://vesselreach.si/blog/which-sanctions-lists-to-check-before-a-port-call) sets out the order of checks. - **Price the war risk into the terms.** Bunker deliveries in a strike zone carry barge and crew exposure. Credit terms should reflect that, as we set out in [bunker fuel credit terms for chandlers and agents](https://vesselreach.si/blog/bunker-fuel-credit-terms-for-chandlers-and-agents). - **Expect the ETA to move.** An ETA (estimated time of arrival, the vessel's declared arrival time at the port) can slip by days when a convoy or clearance is withdrawn. Hold barge slots loosely. - **Log the enquiry, not just the order.** A refused or deferred stem today is a qualified contact for the next call at the same port. Before re-quoting a stem that has already slipped, run a fresh credit check as described in [bunker supplier credit check before re-quoting a stem](https://vesselreach.si/blog/bunker-supplier-credit-check-before-re-quoting-a-stem). ## Where the work moves next Three commercial shifts follow from the sources. First, Gulf producers running their own fleets will bunker on contracts rather than spot. That favours suppliers who can offer volume, consistent quality and documentation across several ports, not the cheapest single stem. Second, the LNG and product tanker trades around Qatar and the UAE remain active despite the attacks, which keeps gas carrier and product tanker stems in play at Gulf ports. Our post on [LNG supply deals and the port call work they create](https://vesselreach.si/blog/lng-supply-deals-port-call-work-they-create) covers how those enquiries arrive. Third, the human cost is now a commercial factor. With 25 seafarers killed since February, crew welfare, medical support and repatriation sit on the same purchase order as fuel for many managers. Suppliers who can answer those requests alongside a bunker quote win the relationship. ## How VesselReach helps Bunkering companies in the Gulf need to know which vessels are heading for their ports, which company is behind each one, and who to call before the ETA moves. VesselReach, built by CatalystIQ, does that in one workflow. - **Vessel intelligence:** VesselReach shows vessels near your selected ports plus scheduled and expected arrivals, which means you can approach the buyer before the ship is alongside. - **AI company targeting and decision-maker discovery:** the platform identifies the relevant company behind each vessel and finds roles such as procurement, operations and chartering, which means fewer manual searches before a stem is quoted. - **Multichannel outreach with follow-ups:** email, WhatsApp and phone outreach is staged and personalised, with automated follow-ups and human handoff on the Android and iOS apps, which means enquiries do not stall while your team is on the barge. Book a VesselReach demo and test it on the ports you actually supply.

Gulf producers are building a fleet of nearly 230 tankers to keep crude exports moving, because independent owners are reluctant to operate there. Sanctioned Iran-linked tankers also continue to burn fuel, often without a clean AIS track. ([MarineLink](https://www.marinelink.com/news/gulf-oil-producers-build-tanker-fleet-544013)) ### How many seafarers have been killed in the Strait of Hormuz since the war began? The IMO said at least 25 seafarers have been killed in the Strait of Hormuz since the US-Iran war began on 28 February 2026, with thousands still stuck in the Gulf. ([Marine Insight](https://www.marineinsight.com/imo-25-seafarers-killed-strait-of-hormuz-since-war-began/?utm_source=rss&utm_medium=rss&utm_campaign=imo-25-seafarers-killed-strait-of-hormuz-since-war-began)) ### Why is AIS data less reliable for bunker sales targeting in the Gulf now? A 2026 paper in IEEE Security & Privacy examined location spoofing, identification manipulation and electronic interference around the Strait of Hormuz. That means a vessel showing a clean arrival may not be the hull or company it appears to be. ([IEEE Security & Privacy](https://doi.org/10.1109/msec.2026.3704691)) ### What checks should a bunker supplier run before accepting a Gulf stem? Confirm the DOC holder and technical manager, screen the vessel and company against sanctions lists, price war risk into credit terms, treat the ETA as movable, and log refused or deferred enquiries as future contacts. ### How can maritime businesses act on the changed buyer mix? VesselReach identifies the company behind each vessel and finds decision-makers by role, so bunker suppliers can reach producer fleets and other buyers before the vessel arrives. ## Sources 1.

The answer has changed. Gulf producers are building their own tanker fleets to keep crude moving, so the stems increasingly come from producer-owned tonnage rather than independent owners who have stepped back. At the same time, some sanctioned tankers are going dark, which makes AIS position data less reliable than usual. For bunkering companies, that means checking the DOC holder, screening the counterparty and pricing war risk into credit terms before accepting a nomination. Watch expected arrivals at your ports, not just ships already alongside, and log every enquiry as a contact for the next call. What is bunkering on a ship? It is fuel delivered to a vessel by barge, and in the Gulf the buyer behind that stem is changing. Who is ordering fuel near Hormuz now? Increasingly producer-owned fleets, because Gulf oil producers are assembling nearly 230 tankers while independent owners hold back. Is AIS still enough to identify a buyer? Not on its own: some sanctioned, Iran-linked tankers went dark over the Gulf of Oman, so confirm the DOC holder and screen the counterparty before quoting. Watch expected arrivals at your ports, not only ships already alongside. The most useful shift for a bunker supplier is the counterparty, not the volume. Gulf oil producers are assembling a fleet of nearly 230 tankers to keep crude exports moving through Hormuz while independent owners hold back, so stems increasingly come from producer-owned tonnage. Because some sanctioned, Iran-linked tankers went dark over the Gulf of Oman, a clean AIS arrival no longer proves who is buying. Confirm the DOC holder and screen the counterparty before the nomination is accepted. Gulf bunker enquiries now arrive from producer-owned fleets rather than independent owners, so the counterparty on the stem matters more than the number of stems. Before quoting, confirm the Document of Compliance holder under the ISM Code and screen the company against sanctions lists, because some Iran-linked tankers went dark over the Gulf of Oman and Automatic Identification System (AIS) tracks no longer prove who is buying. Treat every enquiry at Fujairah, Khor Fakkan or other Gulf ports as a due-diligence event, price war risk into credit terms, and hold barge slots loosely when an estimated time of arrival slips. --- VesselReach, built by CatalystIQ.
