Iran Shipping Update – October 14, 2026

The maritime security environment across the region remains highly volatile. Iranian attacks on commercial shipping in the Strait of Hormuz continue to disrupt maritime traffic, while Iran-backed Houthi threats and attacks around the Bab el-Mandeb pose a renewed risk to shipping through the Red Sea. Meanwhile, the U.S. maritime blockade on Iranian ports continues to severely constrain the regime’s oil exports.

UANI Field Mission to the Malaysian Eastern Outer Port Limits (EOPL) Anchorage

On September 16, the UANI team chartered a typical supply vessel and travelled 100 nautical miles into the South China Sea to witness and expose the illicit activities of the Ghost Fleet in the Malaysian EOPL anchorage.

U.S. Blockade 

On July 14, 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 October 11, U.S. forces have redirected 135 commercial vessels trying to run the blockade, disabled four that didn’t comply, and boarded two to ensure total compliance. Additionally, U.S. forces have destroyed 10 tankers linked to the Islamic Revolutionary Guard Corps (IRGC).

Houthi Blockade

On July 20, Yemen’s Iran-backed Houthis declared a naval blockade against Saudi Arabian ports. Media reports also indicate that the Houthis have seized islands in the Bab el-Mandeb and the port of Mokha.

While Houthi threats and attacks against Saudi-linked shipping initially prompted some tankers to reroute, transits have been slowly rising—likely reflecting a decrease in maritime strikes—according to data published by Joint Maritime Information Center (JMIC). However, the conflict between Saudi Arabia and the Houthis has escalated following a recent series of deadly Houthi strikes targeting Saudi’s King Khalid International Airport as well as threats to critical energy infrastructure. 

Status of the Strait of Hormuz

Since the start of the Iran War, 110 maritime incidents involving commercial vessels have been reported across the Persian Gulf, Strait of Hormuz, and Gulf of Oman. According to the International Maritime Organization (IMO), these incidents have resulted in 24 seafarer deaths.

On October 13, three container ships—the Marshall Island-flagged AL SAADIYAT (IMO 9760598) and the Singapore-flagged vessels GFS GISELLE (IMO 9704661) and GFS PRIDE (IMO 9349045—plus the Barbados-flagged tanker ALFONSO (IMO 9256298) were struck by unknown projectiles while transiting the Strait of Hormuz. The strike on GFS PRIDE resulted in damage and fire on board, with the vessel ultimately sinking. All 21 crew members were safely evacuated, and no injuries have been reported. On October 14, satellite imagery of the location of GFS PRIDE’s strike shows numerous containers floating in the Strait of Hormuz.

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. After the signing of the MoU, JMIC 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 October 10, JMIC has reported a total of 1,047 vessels transiting the Strait of Hormuz since June 18, for a total of 1,660 since the beginning of the war.

In the past months, an increasing number of vessels have been transiting the southern corridor of the Strait of Hormuz bidirectionally without broadcasting AIS location data, with many of these movements facilitated by U.S. forces. U.S.-facilitated transits through the Strait of Hormuz averaged 28.7 vessels per day, with 86 transits recorded during the 72-hour period of October 8–10. This figure brings the month-to-date October total to 414 transits and raises the cumulative campaign total to 2,434 transits. 

Iranian Oil-Laden Tankers Departing the Gulf of Oman

Tankers laden with Iranian oil and petrochemicals are currently clustering in anchorages along the Iranian coastline due to the reinstatement of the U.S. blockade on Iranian ports. Since the blockade resumed, only around nine small tankers carrying Iranian LPG and naphtha have successfully passed the blockade line. However, UANI has not tracked any tanker laden with Iranian crude oil that has successfully 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 54 tankers laden with Iranian oil—primarily crude, but also other petroleum products and LPG—currently operating along the Iranian coastline.

Number of Iranian Loadings

Since the U.S. reinstated the maritime blockade on July 14, UANI has tracked at least 43 Iranian oil and petrochemical loadings, only eight of which originated from Kharg Island, Iran.

Iran-Linked Tankers Globally

UANI has also monitored Iran-flagged tankers operating beyond the Persian Gulf, particularly in the waters near Malaysia. In the days leading up to the UANI team’s trip to the Malaysian EOPL in the South China Sea, it was purported that Malaysian authorities had conducted enforcement actions in the anchorage. Prior to purported recent enforcement actions, seven Iran-flagged tankers had been loitering in the anchorage, namely: HUMANITY (IMO 9180281),STARLA (IMO 9569621), HILDA I (IMO 9357389), DAN (IMO 9357729), HAPPINESS I (IMO 9212905), HEDY (IMO 9212888), and DORENA (IMO 9569669).

DORENA, HEDY, HUMANITY, and STARLA remained in the EOPL and were last observed clustered together in the anchorage in satellite imagery on October 8. These tankers are most likely empty after already conducting STS transfers of Iranian crude.

However, most likely due to recent enforcement actions by Malaysian authorities, the other Iran-flagged tankers had departed the EOPL and transited the South China Sea northbound to anchorages south of Hong Kong and Zhuhai, China. HILDA 1 conducted an STS transfer of Iranian crude oil south of Zhuhai on September 17, while HAPPINESS I conducted an STS of Iranian crude oil south of Hong Kong on September 22. It is not known exactly where DAN relocated to; however, the tanker briefly broadcasted its location on AIS on September 25 transiting the South China Sea southbound towards the EOPL.

In addition, at least 24 tankers listed on UANI's Ghost Armada were anchored or loitering north of the EOPL anchorage with their AIS signals active. These tankers most likely departed the anchorage due to the purported recent enforcement actions of the Malaysian maritime authorities. Meanwhile, about 18 tankers listed on UANI’s Ghost Armadaremain loitering in the EOPL anchorage, demonstrating that Ghost Fleet tankers continue to operate with impunity across Southeast Asia's sea lanes.

Iran-flagged tankers, empty after conducting STS transfers, are now loitering at anchorages across the Indo-Pacific rather than transiting back to Iranian ports because of the U.S. blockade. DIONA (IMO 9569695) is loitering offshore Duqm, Oman, while 20 empty Iran-flagged tankers are currently loitering off Sri Lanka. These tankers are DREAM II (IMO 9356593), STREAM (IMO 9569633), HALTI (IMO 9212890), SEA CLIFF (IMO 9569657), HERO II (IMO 9362073), SILVIA I (IMO 9172052), SNOW (IMO 9569619), HELM (IMO 9357391), DUNE (IMO 9569712), DEEP SEA (IMO 9218492), DIAMOND II (IMO 9218478), DINO 1 (IMO 9569671), SONIA I (IMO 9357365), DORE (IMO 9357717), HERBY (IMO 9362059), SEVIN (IMO 9357353), FELICITY (IMO 9183934), HENNA (IMO 9212929), AMBER (IMO 9357406), and HUGE (IMO 9357183). From August 23, most of these Iran-flagged tankers departed the Galle anchorage and started loitering within the vicinity of Sri Lanka, possibly driven by heightened regulatory or enforcement pressure following press coverage of UANI’s monitoring of Iran-flagged tankers in Sri Lanka’s Exclusive Economic Zone (EEZ). By October 13, all of these tankers had relocated to other Sri Lankan anchorages further north up the coast and are intermittently broadcasting their locations via AIS.

Iran-Flagged Cargo Ships Globally

Despite ongoing pressure of 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 Indian Ocean, the Mediterranean, and the Atlantic.

Along the Iranian coastline in the Gulf of Oman, the falsely flagged container ship ZYRA (IMO 9237084) returned to its previous location near Jask after turning around, despite listing Colombo, Sri Lanka, as its destination. This cargo ship may have been redirected by U.S. naval forces.

Near Karachi, Pakistan, the falsely flagged Iranian-linked container ship BATIS (IMO 9465760) and ARTMAN (IMO 9405930) remained anchored in the Karachi OPL anchorage.

At the Gulf of Kutch in India, SHAMIM (IMO 9270658), VELON 1 (IMO 9122473), and DAISY (IMO 9270684) remained anchored near Kandla Port.

At Mumbai, India, the OFAC-sanctioned and falsely flagged container ship ENZO 2 (IMO 9236652) remained anchored at the Mumbai OPL.

At Port Klang, Malaysia, the container ships VIRA 1 (IMO 9088524) and FLORA (IMO 9349576) remained in port at Berth 10 and 22 for possible transshipment operations. Since both ships are Iran-flagged and OFAC-sanctioned, they expose the commercial port operator, Wesports Holdings, and the ship agent, Q-Express Line, to possible secondary sanctions. Meanwhile, the falsely flagged TAVA 4 (IMO 9292151) is en route from Mumbai to Port Klang with an estimated arrival of October 17.

At the Malaysian EOPL, 17 Iranian-flagged cargo ships were in or near the anchorage: BEHDOKHT (IMO 9405978), DARYABAR (IMO 9369710), PARISAN (IMO 9465851), GOLAFRUZ (IMO 9323833), ANDIA (IMO 9193197), BAHJAT (IMO 9405954), ARDAVAN (IMO 9465863), KASHAN (IMO 9270696), ARZIN (IMO 9284142), PARNIA (IMO 9167265), AMINA (IMO 9305192), ARIES (IMO 9369722), ARTIN (IMO 9305221), GANJ (IMO 9305219), RAYEN (IMO 9820245), ARTABAZ (IMO 9283007), and BARZIN (IMO 9820269). Most of these vessels will likely remain in the EOPL while the U.S. blockade is still in force, receiving regular logistics support from Malaysian service providers, despite the risk of secondary sanctions from OFAC.

In Thailand, the bulk carrier PARSHAD (IMO 9387786) pulled into Siam Commercial Sea Port at Sriracha near Laem Chabang for cargo operations. Meanwhile, the bulk carrier DELNAVAZ (IMO 9387803) remained anchored just south of Phuket Island in the Andaman Sea. 

The container ship SHIBA (IMO 9270646) continued sailing south into Indonesian waters near Natuna Island on its way to Jakarta, Indonesia, with an estimated arrival of October 17.

Meanwhile, AREZOO (IMO 9165786) entered the Gulf of Tonkin on its way to Haiphong, Vietnam, and will likely arrive on October 15.

In the South China Sea, the container ship ALOR 2 (IMO 9228538), which previously departed Zhuhai, continued drifting in international waters.

At Zhuhai, China, the container ships ARTENOS (IMO 9820245) and RADIN (IMO 9820257) remained in the anchorage. Zhuhai Port at Gaolan Island has previously been identified in media reports as a source of precursor chemicals for rocket fuel. 

Near Shanghai, the container ships ASYAN (IMO 9165803) and ABYAN (IMO 9349667) remained anchored at CJK anchorage, while SHABDIS (IMO 9349588) arrived and joined them in the anchorage.

In the Red Sea, the Iranian flagged container ship NYRA 2 (IMO 9241487) continued sailing toward the southern entrance to the Suez Canal.

The general cargo ship ALVAN (IMO 9165798) continued sailing from Misrata, Libya, toward Port Said and the Suez Canal. 

Meanwhile, in the Mediterranean Sea, the Iranian-flagged container ship FLEXI 2 (IMO 9246322) continued past the Gibraltar Strait toward Port Said anchorage with an estimated arrival of October 21.
