Iran Shipping Update – July 28, 2026

The United States reinstated its naval blockade of Iranian ports on July 14 following Iran's attacks on commercial vessels transiting the Strait of Hormuz starting July 7. This reignited tensions across the Persian Gulf, ultimately resulting in the apparent collapse of the U.S.-Iran Memorandum of Understanding signed June 17. The United States has since conducted a series of strikes against Iranian military and IRGC maritime assets, while Iran has continued to attack commercial shipping and Gulf States.

U.S. Blockade 

On July 14 at 4 p.m. ET, U.S. forces reimposed the blockade against vessels transiting to or from Iranian ports and coastal areas while supporting compliant traffic in regional waters. As of July 28, U.S. forces have redirected 18 commercial vessels trying to run the blockade, disabled 2 that didn't comply, and boarded 2 to ensure total compliance.  

Houthi Blockade

On July 20, Yemen’s Iran-backed Houthis declared a naval blockade against Saudi Arabian ports. On July 22, the Houthis claimed they attacked two tankers laden with Saudi crude oil in the Red Sea. JMIC also reported that a tanker was hit by projectiles and was fighting a fire near the mouth of the Bab el Mandeb strait approximately 70nm off the coast of Saudi Arabia. Houthi threats and attacks against Saudi-linked shipping are already prompting some, but not all, tankers to reroute in the Red Sea. According to Windward, transits of the Bab el Mandeb have fallen by 22% since the Houthi blockade.

Status of the Strait of Hormuz

Since the start of the Iran War, the International Maritime organization (IMO) has reported 62 maritime incidents involving commercial vessels have been reported across the Persian Gulf, Strait of Hormuz, and Gulf of Oman.

Prior to the outbreak of the Iran War, about 138 vessels transited the Strait of Hormuz daily. Throughout the conflict, marine traffic data showed large clusters of loitering vessels on both sides of the Strait of Hormuz, with many ships refraining from transiting due to safety concerns. Since the signing of the MoU, the Joint Maritime Information Center (JMIC) has reported an increase in open transits through the Strait of Hormuz. On June 24, JMIC recorded 54 transits, the highest daily total since the outbreak of the conflict. As of July 27, JMIC has reported a total of 723 vessels transiting the Strait of Hormuz since the date of the signing of the MoU.

Open transits of commercial vessels through the southern corridor of the Strait of Hormuz declined following the IRGC strikes on commercial shipping starting July 7 but have not ceased entirely. Since the strikes, the traffic has been dominated by Iranian- and Chinese-linked vessels transiting via the northern corridor.

Iranian Oil-Laden Tankers Departing the Gulf of Oman

Since the announcement of the MoU on June 14, UANI has tracked 66 tankers departing the Gulf of Oman laden with Iranian oil and petrochemicals. These exports represent approximately 80 million barrels of Iranian oil, generating an estimated revenue of over $6 billion for the IRGC, which continues to fund Iran’s missile and drone programs. These figures are estimates. The pricing and volumes associated with Chinese purchases of Iranian crude are not publicly disclosed, though such cargoes are widely assessed to be sold at a discount of around 10 to 12 dollars per barrel.

Tankers laden with Iranian oil and petrochemicals are currently clustering in anchorages along the Iranian coastline due to the U.S. blockade on Iranian ports. UANI has not tracked any tanker laden with Iranian crude oil that has departed the Gulf of Oman and avoided enforcement actions by U.S. forces since July 12, before the blockade was reinstated. 

Iranian Oil-Laden Tankers

UANI has identified at least 45 tankers laden with Iranian oil — primarily crude, but also other petroleum products and LPG — currently operating along the Iranian coastline.

Four laden tankers were observed loitering just south of Jask Port, Iran in satellite imagery on July 28. Together, they are carrying approximately 7 million barrels of Iranian oil. The vessel on the far left of the image below is LAN JING (IMO 9288095) which was previously boarded by U.S. forces as part of their blockade enforcement measures on July 16 and then diverted back to Iranian waters.

Number of Iranian Loadings

Since the signing of the U.S.-Iran MoU on June 17, UANI has tracked at least 31 Iranian oil and petrochemical loadings, 12 of which originated from Kharg Island, Iran. 

Iran-flagged Tankers Globally

UANI has also monitored Iran-flagged tankers operating beyond the Persian Gulf. Since the signing of the MoU, 26 Iran-flagged tankers have reached the Singapore Strait bound for the EOPL anchorage off Johor, Malaysia.

There are 19 Iran-flagged tankers currently in the EOPL: HUMANITY (IMO 9180281), DREAM II (IMO 9356593), DUNE (IMO 9569712), STARLA (IMO 9569621), HILDA I (IMO 9357389), DAN (9357729), HELM (IMO 9357391), HALTI (IMO 9212890), HAPPINESS I (IMO 9212905), STREAM (IMO 9569633), DIAMOND II (IMO 9218478), DINO 1 (IMO 9569671), HEDY (IMO 9212888), DORE (IMO 9357717), SILVIA I (IMO 9172052), DORENA (IMO 9569669), SNOW (IMO 9569619) HERO II (IMO 9362073) and SONIA I (IMO 9357365). They have all previously passed the Singapore Strait and have since stopped broadcasting their location on AIS. All these Iranian tankers are expected to conduct STS transfers in the EOPL. Nine of these STS transfers have been observed in satellite imagery. Two Iran-flagged tankers and another Ghost Armada tanker all conducted STS transfers of Iranian crude on July 28 in the anchorage.

HERBY (IMO 9362059), SEVIN (IMO 9357353), FELICITY (IMO 9183934), HENNA (IMO 9212929), AMBER (IMO 9357406) and DIONA (IMO 9569695) have all departed from the EOPL in ballast after completing STS transfers. These departing Iran-flagged tankers are now most likely heading to anchorages across the Indo-Pacific rather than back to Iranian ports because of the U.S. blockade.

DIONA was last observed loitering offshore Duqm, Oman in satellite imagery on July 23, while SEVIN, AMBER, HENNA and FELICITY are currently anchored off Galle, Sri Lanka according to AIS. STARLA also left the EOPL empty, conducted another STS in the Malacca Strait, and has since returned to the EOPL laden with Iranian crude, bringing the total to seven Iran-flagged tankers that have departed the EOPL empty since the signing of the MoU, which has since collapsed.

Iran-flagged HUGE (IMO 9357183) has also departed the EOPL anchorage and is currently transiting the Malacca Strait. This tanker has been loitering unladen in the EOPL anchorage for over two weeks after conducting an STS transfer of Iranian crude south of Hong Kong in the South China Sea on July 9. 

On July 28, at least 55 tankers listed on UANI's Ghost Armada were anchored or loitering near the EOPL area with their AIS signals active, demonstrating that ghost fleet tankers continue to operate with impunity across Southeast Asia's sea lanes. 

Iran-Flagged Cargo Ships Globally

Despite ongoing pressure of U.S. OFAC sanctions, and new constraints of the U.S. Blockade on Iranian ports, approximately 50 Iranian flagged cargo ships continue to operate openly across sea lanes, ports, and anchorages throughout the Indo-Pacific region, the Red Sea, the eastern Mediterranean and the Baltic Sea.

No Iranian-flagged cargo ships have openly crossed the U.S. blockade line since it was formally declared on June 14. 

In the Mediterranean Sea, the Iran-flagged general cargo ship ALVAN (IMO 9165798) remains anchored outside Benghazi, Libya, while AYSAN (IMO 9165803) got underway and departed Misrata for the Suez Canal.  Libya is under certain UN sanctions, and an arms embargo, in accordance with United Nations Security Council Resolution 2819 (2026).

The general cargo ship NYRA 2 (IMO 9241487) is transiting the Suez Canal today toward the Red Sea. It previously departed a Russian port on the Black Sea without broadcasting on AIS and then passed the Bosphorus on July 25. Its destination after passing the Suez Canal is unknown, but it is possible that it will visit Port Klang, Malaysia, as similar vessels have done previously.

The bulk carrier BATIS (IMO 9465760) arrived near the Karachi OPL anchorage, despite listing Bandar Abbas as its destination. BATIS stopped and loitered for about twelve hours before turning and beginning to sail west in the Gulf of Oman. It remains to be seen if it will sail to the boundary line of the U.S. blockade or stay in the vicinity of Karachi, Pakistan.

Both bulk carrier ARTMAN (IMO 9405930) and container ship ARTAM (IMO 9284154) are anchored outside the Gulf of Kutch. The container ships VELON 1 (IMO 9122473) and ENZO 2 (IMO 9236652) are anchored outside Mumbai, after turning around in the Gulf of Oman, likely in response to the U.S. blockade and to avoid interdiction by U.S. naval forces.

FLEXI 2 (IMO 9246322) is sailing west in the Gulf of Aden toward the Bab al-Mandab strait, on its way to the Suez Canal, from Kandla, India.

The container ship ZYRA (IMO 9237084) passed the Laccadive Sea, sailing northward along the west coast of India returning to the Persian Gulf. On AIS, ZYRA lists its destination as Jebel Ali, UAE but ZYRA is most likely not heading there and will instead wait in the vicinity of Karachi due to the U.S. Blockade.

Meanwhile, the container ship VIRA 1 (IMO 9088524) continued crossing the Arabian Sea, en route to Port Klang, Malaysia, after previously visiting the Russian Baltic.

The container ship SHAMIM (IMO 9270658) transited the Six-Degree Channel and entered the Bay of Bengal, sailing west.  Its destination in unknown.

The container ships DAISY (IMO 9270684), SHIBA (IMO 9270646) and ARTABAZ (IMO 9283007) remained at the Port Klang anchorage.

The container ships BASHT (IMO 9346536) and ALOR 2 (IMO 9228538) and the general cargo ship PARNIA (IMO 9167265) remained anchored in the Malaysian EOPL area. The container ship ARTENOS (IMO 9283021) departed the EOPL today and began to sail north into the South Chian Sea to Zhuhai, with an estimated arrival of August 2.

The bulk carrier BEHDOKHT (IMO 9405978) was moored in port at Sri Racha port, near Laem Chabang, Thailand. Meanwhile, the general cargo ship AREZOO (IMO 9165786) appeared again on AIS today in port at Tanjong Priok in Jakarta after previously visiting Surabaya, Indonesia.

At the Zhuhai container terminal, the container ship HAMOUNA (IMO 9820271) was joined by RAMA 3 (IMO 9303754) today. It is possible that these two ships are conducting transhipment operations. HAMOUNA arrived from Bandar Abbas and conducted some unusual loitering manoeuvrers in the Yellow Sea before visiting Shanghai at the same time as RAMA 3. Meanwhile, RAMA 3 visited Port Klang, Zhuhai and Shanghai, after departing from the Russian Baltic in late May 2026. In addition, RADIN (IMO 9820257) remains anchored near Zhuhai, from Bandar Abbas, where it departed on July 8, prior to the reinstatement of the blockade.

Five container ships are currently anchored at CJK anchorage off Shanghai, China. The bulk cargo ship AMINA (IMO 9305192) has appeared again on AIS and joined the five ships in CJK anchorage. Another container ship previously anchored here is likely still in port at Shanghai terminals, but due to Chinese regulations, the AIS signal is not visible. China implemented data security laws that significantly restricted the export of certain geographic and transport data. Many domestic AIS shore stations stopped providing their data to foreign commercial AIS aggregators. The container ship KASHAN (IMO 9270696) is approaching Shanghai after previously departing Zhuhai and will likely arrive at CFJ anchorage by July 29.

Three bulk cargo ships are currently at Dafeng, while two other bulk cargo ships are in port at Zhoushan, China. ANDIA (IMO 9193197) arrived at Zhoushan after being towed all the way form the Malaysian EOPL and berthed next to BAHJAT (IMO 9405954). Both are likely in port for lengthy shipyard repairs.

The container ship BEHTA (IMO 9349590) is passing south through the Baltic Sea, with its destination is listed as Port Said, Egypt. BEHTA will likely transit the Dover Strait on July 31. According to the Equasis and TokyoMoU Port State Control databases, BEHTA is a “High Risk Ship, Priority I” ship for poor Flag State performance and compliance with safety regulations, as well as records of deficiencies on previous inspections. EU Directive 2025/811 required Mandatory Ship Reporting of key safety information, including insurance certificates due to substandard ships that pose substantial risks to maritime safety and marine ecosystems.
