As CENTCOM and the IRGC issue conflicting claims about the Strait of Hormuz, Windward's MSI analysis from 02:10 UTC today assessed three vessels transiting dark through the deep-water channel (two northwest, one north at high confidence). AIS tells a similar story: five total transits recorded across June 10–11 (four outbound coastal cargo vessels under 80m, one inbound general cargo). When the narratives diverge, vessel behavior is where the picture becomes clearer. okt.to/iCbhkr

Settebello (IMO 9162916), a dark fleet tanker used exclusively to ship Iranian fuel oil and heavy crude, tells a familiar story: 6 reflags in 6 years, a fraudulent ship registry, no known marine insurance, and 3 commercial controllers since 2020. Behavioral patterns don't lie. Windward tracked its repeated AIS spoofing to mask loadings from Bandar Mahshahr.

Live today at 9:00 AM BST / 4:00 PM SGT. We go live in a few hours to break down exactly how war risk is priced right now, who pays under BIMCO clauses, and what Hormuz volatility means for your exposure. Final chance to join @Michellewb_ (Windward), Mark Church (@NSMarineIns), and David Mckie (Preston Turnbull). Secure your spot: okt.to/LNTl8m

Customs enforcement built its screening model on clean paperwork. Adversaries built their operations around exploiting it. 290 tankers broadcasting fraudulent flags. 978K GPS jamming incidents in a single quarter. The ARCONIAN flagged as a smuggling risk 4 months before interception. Behavioral intelligence is the new screening model. okt.to/JavgXR

Talking Hormuz tomorrow with marine insurance executive briefing - sign up below

Five Iranian-trading LPG carriers have broken the U.S. blockade on Iranian ports. Four discharged in India, one in Pakistan. All five used the same playbook, spoofing and AIS blackouts to mask loading and destination. Yet all signaled their exit and/or entry through Hormuz via AIS. Three were already U.S.-sanctioned. A fourth sanctioned June 6. Two operated under false flags, making them legally stateless. The crude blockade is holding. No Iran-trading VLCC tracked in Asia via Malacca, Sunda, or Lombok since May 4. But LPG is still getting through to India and Pakistan. Via @Vortexa data and Windward analysis.

With the Gulf redesignated as a high-risk Listed Area, how are marine insurers calculating the true cost of war risk? Tomorrow at 9:00 AM BST, join our live Executive Briefing to analyze the real-world application of BIMCO clauses, facilitation fees, and dark fleet exposures in the Strait of Hormuz. Expert insights from @Michellewb_ (Windward), Mark Church (@NSMarineIns), and David Mckie (Preston Turnbull). Register: okt.to/9mwUy6

The Strait of Hormuz, June 8–9: 8 transits tracked (2 inbound, 6 outbound). Key signals from Windward's Maritime AI™ platform: • Inbound vessel near Seerik, Iran (June 8): AIS linked to an OFAC-sanctioned tanker. Fraudulent flag. Dark for 3 days after outbound crossing on June 5. • Second inbound (June 8): last port call Iran, no declared destination. Route consistent with Iran–Oman trade. • Outbound oil tanker: multiple dark periods, possible jamming. Last port call Siri Island, Iran. No declared next port. • Outbound tanker departed Iraq on June 6, crossed south of Larak Island night of June 8–9. Declared destination consistent with past behavioral pattern. Behavior surfaces what declarations conceal. Follow our daily Hormuz dashboard for the full picture. okt.to/eVZqno

Windward's MIOC dashboard now tracks Red Sea vessel activity daily, covering Bab-el-Mandeb and Suez crossings, fleet composition, and smuggling risk across hundreds of vessels. Alongside Hormuz transits, Gulf dark activity, and GPS jamming data. Updated every 24 hours. okt.to/wY0fEv

80 commercial ships have crossed the Strait of Hormuz in 5 weeks, most of them dark. Windward tracked each one. Some negotiated passage with Iran. Others moved with U.S. support. Negotiations are deadlocked, but vessels are moving anyway. okt.to/TDyVix

Hormuz. The Gulf. GPS jamming. And now: the Red Sea. Windward's daily intelligence dashboard tracks dark transits, vessel risk, and chokepoint flows across the maritime corridors that move global trade. Updated every day. okt.to/ETsURQ

9 AIS-recorded Hormuz transits | 07–08 Jun 5 outbound, 4 inbound. Multiple vessels flagged: OFAC/EU designations, fraudulent flag registration, extended dark activity, persistent AIS manipulation. Behavioral signals tell a different story than the AIS feed. Daily tracker: okt.to/RaUQST

Eleven days after an oil spill halted operations at Kharg Island's eastern terminal, the picture remains static. One tanker, ~181m, south berth of the eastern T-jetty. Day five alongside. Still in ballast. AIS dark. Six tugs drifting east. No loading visible.

An OFAC-sanctioned tanker has been static 15nm west of Khasab, at the mouth of the Strait of Hormuz, for 15 hours. Fraudulent flag. No ownership data. AIS frozen in place. @Vortexa registers 110.3k bbl of gasoline/blending components aboard. Last reported port of call: Kohr Al Zubair, Iraq (volume data is consistent with a completed loading cycle). Next port of call: Port Sultan Qaboos, Oman. Windward assesses this vessel as a potential blockade breaker. Daily Hormuz & Red Sea tracking: okt.to/7ECAUq

MT MARIVEX (IMO 9464156), a Palau-flagged oil products tanker sanctioned under the Iran program for a call at Shahid Rajai in April 2026, is now anchored off Oman following a reported onboard fire and full crew evacuation. The vessel is transmitting AIS but stationary, with no declared destination. The voyage pattern: Shahid Rajai in April, then New Mangalore, Karwar, and an STS meeting in UAE waters before going dark on destination. More to follow.

654 vessels in the Red Sea. 80 high risk. 19 inbound / 34 outbound through Bab-el-Mandeb. Now tracked daily alongside Hormuz transits, 714 jammed vessels in the Gulf, and live dark-activity data. okt.to/HtVy8b

Dual-use activity isn't invisible. It's just hard to see without the right behavioral models. Maritime AI™ changes that. windward.ai/industries/offsh…

Smuggling networks and deceptive fleets outpace conventional inspection capacity. The data to stop them exists, but it’s fragmented and arrives too late. On June 17, join Windward's @Michellewb_ for a hands-on workshop to analyze: - The 1.5% threshold narrowing thousands of regional vessel movements down to the actionable few. - The Russian shadow fleet, tracing complex tanker ownership and sanctions exposure.
