Iranian Retaliation Reaches Damietta: A New Front Opens Beyond the Gulf and the Red Sea

At a Glance

• A drone struck ENERGOS WINTER, a U.S.-managed LNG floating storage unit at Damietta, Egypt, on July 29, with fire spreading to a second LNG tanker alongside.
• Iranian state television had named Damietta as a retaliation target two days earlier, citing Ukraine’s strike on an Iranian vessel in the Caspian Sea, pointing to an Iranian-directed operation separate from the Houthi campaign.
• OFAC sanctioned two firms running an IRGC-backed Hormuz extortion scheme, the Persian Gulf Marine Insurance Company and HormuzSafe Marine Services Authority, alongside eight shadow fleet vessels.
• A Chinese-flagged bulk carrier completed a full transit from China to Jeddah through Bab el-Mandeb during the active Houthi blockade, confirming the China-Houthi safe passage arrangement is operational in practice.
• Hormuz recorded 20 transits on July 29, with 55 IRGC high-speed craft documented across multiple swarms.
• The dark tanker cluster above Larak Island grew from 14 to 18 vessels, with 17 of 18 now dark.
• Kharg Island’s three export terminals were all empty on July 29, with the western terminal without a berthed vessel for 11 days.
• Yanbu King Fahd Industrial Port has sustained fully dark high-tempo loading for a fourth consecutive day.

Operational Overview

The conflict’s geographic footprint has expanded beyond the Gulf and Red Sea into the broader eastern Mediterranean energy corridor. A drone struck ENERGOS WINTER, a U.S.-managed LNG floating storage unit moored at Damietta, Egypt, on the evening of July 29, with fire spreading to GASLOG SALEM alongside. Iranian state television had named Damietta as a retaliation target two days earlier, citing Ukraine’s strike on an Iranian vessel in the Caspian Sea, pointing to an Iranian-directed operation rather than a Houthi one.

OFAC simultaneously moved against the financial architecture underpinning Iran’s Hormuz operations, designating two firms running an IRGC-backed extortion scheme that forces commercial vessels to purchase mandatory insurance to transit the Strait, alongside eight shadow fleet vessels for transporting Iranian crude and petrochemical products.

The China-Houthi safe passage arrangement is now confirmed operational at the vessel level. A Chinese-flagged bulk carrier completed a full China-to-Jeddah transit through Bab el-Mandeb during the active Houthi blockade of Saudi-linked shipping, using nationality-signaling AIS declarations throughout with no incident. Saudi-linked vessels face active targeting in the same corridor.

Hormuz continues to operate under IRGC pressure. 20 transits were recorded on July 29 with 55 IRGC high-speed craft documented across multiple swarms, an abnormally elevated small-boat presence. The dark tanker cluster above Larak Island grew from 14 to 18 vessels. Kharg Island’s three export terminals were all empty. Yanbu King Fahd port has sustained fully dark high-tempo loading for a fourth consecutive day, confirming Saudi crude exports continue despite the Houthi blockade and Lloyd’s war risk insurance withdrawal.

Windward assesses the operational risk environment across the Strait of Hormuz, Red Sea, Gulf of Aden, northern Arabian Gulf, and now the eastern Mediterranean as critical, with Iranian retaliation reaching Egyptian energy infrastructure, active corridor enforcement across the Gulf, and differential access rules now visibly operating across both major waterways.

A Drone Strike on LNG Tankers at Damietta, Egypt

A drone struck ENERGOS WINTER (IMO 9256614), a U.S.-managed Marshall Islands-flagged LNG floating storage unit of 277 meters moored at Damietta, Egypt, during cargo discharge on the evening of July 29, with fire spreading to GASLOG SALEM (IMO 9638915), a Bermuda-flagged LNG tanker of 285 meters. Both crews were evacuated, fires were brought under control, no casualties were reported, and both vessels had departed the port area by the morning of July 29. No group has claimed responsibility.

The strike is assessed as separate from the Houthi Saudi-blockade campaign. Iranian state television had named Damietta as a retaliation target two days earlier, citing Ukraine’s strike on an Iranian vessel in the Caspian Sea, pointing toward an Iranian-directed operation rather than a Houthi one. Egypt’s Petroleum Ministry confirmed the incident without publicly identifying the cause.

Both vessels were confirmed departing the port area northbound following the incident per Windward tracking, consistent with open-source reporting of relocation outside the port following the fire.

OFAC Sanctions the Iranian Hormuz Extortion Network and Eight Shadow Fleet Vessels

On July 29, 2026, OFAC designated two firms integral to an IRGC-backed extortion scheme that forces commercial vessels to purchase mandatory maritime insurance to transit the Strait of Hormuz, the Persian Gulf Marine Insurance Company and HormuzSafe Marine Services Authority. The insurance covers risks overwhelmingly created by Iran itself, such as vessel seizures, and is designed to extract revenue under the guise of maritime services, including payments in digital assets to evade sanctions.

OFAC also sanctioned eight shadow fleet vessels for transporting Iranian crude oil and petrochemical products, designating the following:

• WELL SAIL (IMO 9321938), a Marshall Islands-flagged chemical and products tanker owned, operated, and managed by China-based Qi Hang Ship Management.
• LILY (IMO 9294331), a Mozambique-flagged crude tanker owned and operated by Hong Kong-based Confident Apex Limited.
• AL SALMI (IMO 9298296), an unknown-flagged crude tanker owned and operated by Hong Kong-based Billion Nexus International.
• BREEZE V (IMO 9259355), a Barbados-flagged crude tanker owned and operated by Hong Kong-based Nevada Spirit Company Limited.
• NATSUMI (IMO 9331244), a Barbados-flagged crude tanker owned, operated, and managed by Hong Kong-based Marinova Freight Limited. 
• CRYSTAL (IMO 9223887), a Vanuatu-flagged crude tanker owned, operated, and managed by Hong Kong and Marshall Islands-based Vast Mighty Limited.
• NIRETA (IMO 9237785), a Vanuatu-flagged crude tanker owned, operated, and managed by Marshall Islands-based Ocean Tranquility Limited. 
• YEHOPE (IMO 9243320), a Barbados-flagged crude tanker owned by Marshall Islands-based Branch Saying International Trading Company Limited.

Since the beginning of the year, OFAC has sanctioned over 100 vessels linked to Iran’s shadow fleet.

The China-Houthi Safe Passage Arrangement Is Operational

A Chinese-flagged bulk carrier completed a full transit from China to Jeddah through Bab el-Mandeb during the active Houthi blockade of Saudi-linked shipping, using defensive AIS destination declarations throughout, signaling Chinese nationality and crew through the chokepoint.

The vessel switched its AIS destination to Chinese ownership and armed guard declarations before entering high-risk waters, then to a Chinese ship and crew declaration through the Bab el-Mandeb, before reverting to a standard Saudi destination declaration in the northern Red Sea past the threat zone. No dark activity, no GPS manipulation, and no course deviations were recorded throughout the transit.

The case directly confirms that the China-Houthi safe passage arrangement, which moved from talks to a reported fee-exemption structure this week, is operational in practice. Open-source reporting indicates that China held direct talks with the Houthis to secure vessel-specific safe passage for Chinese tankers, with both parties briefing Iran on the arrangement. Separately, the Houthis are reported to be weighing fees on most Bab el-Mandeb traffic while exempting Chinese vessels.

Three vessels of interest were identified transiting Bab el-Mandeb on July 29 at 08:02 UTC. A Bahamas-flagged bulk carrier of 196 meters was inbound transmitting AIS with a Chinese crew declaration, the same signaling pattern as the Chinese-flagged Jeddah transit, and carries a high-risk compliance flag linked to Russia, making it the primary concern among the three. A Marshall Islands-flagged bulk carrier of 225 meters was outbound following a Russia-origin voyage heading toward India, with no Saudi connection identified, but the Russia-origin routing warrants continued monitoring. A dark container vessel of approximately 163 meters was transiting inbound with identity unconfirmed.

Hormuz Transits and IRGC Presence

July 29 recorded 20 transits, made up of 10 inbound and 10 outbound. The inbound group comprised 6 AIS-transmitting and 4 dark vessels. By vessel type, 5 were tankers under Bahamas, Malawi, Marshall Islands, and Liberia flags, 3 cargo vessels under Iran and Bolivia flags, 1 bulk carrier under Malta flag, and 1 unclassified vessel under Malawi flag. Seven transited via the northern corridor, 2 via the southern corridor, and 1 via unknown routing.

The outbound group comprised 9 AIS-transmitting and 1 dark vessel. By vessel type, 4 were bulk carriers under Liberia, Iran, Panama, and Sierra Leone flags, 3 tankers under Marshall Islands, Barbados, and Bahamas flags, 2 cargo vessels under Iran flag, and 1 other vessel under Iran flag. Eight transited via the northern corridor, 1 via the southern corridor, and 1 via unknown routing.

EO imagery collected over the Strait on July 29 at 07:00 UTC identified 6 inbound and 1 outbound vessel, alongside 55 IRGC high-speed craft across multiple swarms, comprising groups of 3, 4, 5, 6, 15, and at least 18 craft, representing an abnormally elevated small-boat presence and a heightened risk environment for transiting vessels. The inbound group comprised two AIS-transmitting vessels, an Iran-flagged cargo vessel of approximately 50 meters and a Bahamas-flagged tanker of approximately 120 meters, alongside two dark tankers of approximately 120 and 183 meters and one additional small cargo vessel. The sole outbound contact was a dark container vessel of approximately 170 meters transiting via the northern corridor.

The stationary dark tanker cluster above Larak Island grew from 14 to 18 vessels between the prior and current collections, with 17 of 18 now dark against 11 dark in the prior pass. Six new stationary arrivals were identified west of Larak Island, including an OFAC-sanctioned Guyana-flagged tanker under the Iran program, two large dark container vessels of approximately 292 and 286 meters, and three additional dark tankers and cargo vessels. An LPG tanker of approximately 235 meters has remained stationary west of Sirik since July 26.

Kharg Island Terminals All Empty

EO imagery collected over Kharg Island on July 29 at 03:16 UTC showed all three export terminals empty, extending a recent period of decreased loading activity. The western terminal has been without a berthed vessel for 11 days, the eastern terminal since July 25, and the LPG terminal since the vessel observed on July 27 departed. Coverage on this pass was narrower than usual, limiting the total waiting area count. Three dark tankers were confirmed in the waiting area, made up of a VLCC of approximately 333 meters in ballast assessed as holding since at least July 12, a Suezmax of approximately 257 meters in ballast assessed as holding since at least July 18, and a VLCC of approximately 333 meters laden assessed as holding since at least May 14.

Yanbu Sustains Fully Dark High-Tempo Loading for a Fourth Day

EO imagery collected over King Fahd Industrial Port at Yanbu on July 29 at 07:32 UTC confirmed a sustained dark loading operation across the terminal and offshore waiting area. Twelve dark vessels were alongside berths, comprising bulk carriers and tankers with 5 new arrivals, plus two active ship-to-ship transfer pairs in the offshore waiting area, one of approximately 145 meters and one of approximately 102 meters, alongside 4 additional dark holding tankers. A dark laden tanker of approximately 333 meters was confirmed departing the terminal assisted by 3 support craft, continuing the active vessel cycling documented since July 27.

The July 30 collection at 07:16 UTC showed 17 vessels in total, all dark. Five dark bulk and general cargo vessels were at the northern berth line, ranging from approximately 143 to 204 meters. Six dark tankers were at berth, with 4 continuing from the prior pass and 2 new arrivals. Six dark tankers were holding stationary in the offshore waiting area with one additional vessel transiting inbound. No ship-to-ship transfer activity was observed in this pass, versus two active ship-to-ship pairs in the prior collection, noted as a pass-to-pass observation rather than a confirmed cessation given coverage and timing differences.

The transition from AIS-active to entirely dark operations has now been sustained continuously since July 27, with all vessels at berth and in the waiting area suppressing AIS to shield themselves from the Houthi targeting list.

Hodeidah Port: Pre and Post-Strike Comparison

EO imagery collected over the Port of Hodeidah on July 21 and July 28, bracketing the July 24 to 25 Saudi-led coalition strike on Houthi military sites in Hodeidah governorate, shows port activity increasing rather than decreasing across the strike window. The July 21 pre-strike collection showed 3 vessels with no dark contacts. The July 28 post-strike collection showed 5 vessels with 1 dark contact, including 2 new arrivals not present in the prior pass.

The Saudi-led coalition stated explicitly that Hodeidah Port was not targeted and that all Yemeni ports remain open to maritime navigation. Houthi officials disputed this, claiming the port was struck. The imagery directly corroborates the coalition’s account, as a port that had been struck and damaged would not show increased vessel activity three days later.

Voyage histories of the vessels present raise sanctions and smuggling concerns. One bulk carrier arrived from Russia via Djibouti. A container vessel and a bulk carrier both arrived from Djibouti after stationary periods there exceeding six months. A fourth vessel completed a Malaysia-Somalia-Djibouti-Hodeidah route over the prior six months, consistent with established smuggling corridor patterns.

Horn of Africa Seized Tankers Update

Four tankers previously seized by Somali forces and held in waters off the Horn of Africa are being tracked by Windward across multiple collection windows. EO imagery collected over the Horn of Africa on July 29 at 07:07 UTC confirmed HONOUR 25 (IMO 1099735) AIS-active at its previously documented position. SWARD (IMO 9174244) was newly present in the collection area, dark and stationary at a position approximately 0.02 degrees east of HONOUR 25. ASANA was not present in today’s collection, with its latest confirmed position from July 24. EURIKA’s last confirmed position dates to July 21 and was not included in today’s collection footprint.

Outlook

The conflict’s operating map has expanded again. Iranian retaliation has now reached the eastern Mediterranean, with the Damietta LNG strike introducing a new front separate from both the Gulf and Red Sea theaters and directly linked to the Ukraine-Caspian strike. Egypt is now on the active threat picture, and the vessel-relocation pattern following the strike matches the operational response seen at Yanbu and other targeted ports.

The financial and access architecture underpinning both fronts is also visibly shifting. OFAC has moved against the Hormuz extortion scheme’s core entities and eight additional shadow fleet vessels. The China-Houthi safe passage arrangement is operational in practice, confirmed at the single-vessel level with a Chinese-flagged bulk carrier completing a China-to-Jeddah transit through the active Houthi blockade using nationality-signaling AIS declarations. Saudi-linked vessels face active targeting in the same corridor.

Operationally, both waterways continue to run under altered conditions. Hormuz sees IRGC high-speed craft presence at abnormally elevated levels, the Larak dark cluster grew from 14 to 18 vessels, and Kharg’s three terminals were all empty on July 29. Yanbu is on a fourth consecutive day of fully dark high-tempo loading, confirming Saudi crude exports continue despite the Houthi blockade and Lloyd’s war risk insurance withdrawal.

Windward assesses the operational risk environment across the Strait of Hormuz, Red Sea, Gulf of Aden, northern Arabian Gulf, and now the eastern Mediterranean as critical, with Iranian retaliation reaching Egyptian energy infrastructure, active corridor enforcement across the Gulf, and differential access rules now visibly operating across both major waterways.
