Iran Shipping Update – November 2, 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.

For UANI’s recommendations for U.S. sanctions on Iran following “Economic D-Day,” read here.

Status of the Strait of Hormuz

Since the start of the Iran War, the International Maritime Organisation (IMO) has confirmed 123 maritime incidents involving commercial vessels across the Persian Gulf, Strait of Hormuz, and Gulf of Oman. According to the IMO, these incidents have resulted in 24 seafarer deaths.

In the past months, an increasing number of vessels have transited 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 surged to 39.7 vessels per day, with 119 transits recorded during the closing 72-hour period of October (October 29–31). The full monthly total for October is 956 transits across 31 days at 30.8 per day, pushing the cumulative campaign total to 3,089 transits at an overall average of 23.1 per day across 134 monitored days.

Today, multiple vessels were spotted in satellite imagery transiting the southern corridor of the Strait of Hormuz.

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. As of October 31, U.S. forces have redirected 144 commercial vessels trying to run the blockade, disabled four that didn’t comply, and boarded two to ensure total compliance.

Since the blockade resumed, approximately 11 small tankers carrying Iranian LPG 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 56 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 53 Iranian oil and petrochemical loadings, only eight of which originated from Kharg Island, Iran. On November 1, numerous tankers were observed moored at Assaluyeh Port, Iran, and two were loading Iranian LPG.

Iran-Linked Tankers Globally

UANI has also monitored Iran-flagged tankers operating beyond the Persian Gulf, particularly in the waters near Malaysia. At least 21 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 21 tankers listed on UANI’s Ghost Armada remain loitering in the EOPL anchorage, demonstrating that Ghost Fleet tankers continue to operate with impunity across Southeast Asia's sea lanes.

Today, one STS transfer was observed in satellite imagery taking place in the EOPL anchorage near four empty Iran-flagged tankers.

Iran-flagged tankers, empty after conducting STS transfers in the EOPL, 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). Between October 23 and 26, at least six of these tankers transited back towards the Galle anchorage and then returned to the anchorages further north up the Sri Lankan coastline.

On October 24, Sri Lanka coordinated the evacuation of 40 Iranian seafarers from 19 commercial vessels operating in international waters off its coast following reported medical emergencies, according to the country’s foreign ministry. The seafarers were brought ashore at Galle Harbour, where they received medical treatment before being repatriated to Iran.

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, Indian Ocean, Mediterranean, Atlantic Ocean, and Baltic Sea.

The container ship NYRA 2 (IMO 9241487) entered the English Channel and is headed to St Petersburg, Russia, from Mumbai, with an estimated arrival of November 9. The Dover Strait is a mandatory reporting area, and ships passing through the UK section may be required to provide proof of valid insurance when requested by UK authorities, even if they are not calling at a UK port.

The container ship BASHT (IMO 9346536) pulled into port at Benghazi, Libya. Its previous port visits were to Zhuhai and then Port Klang, continuing a pattern of Iranian cargo ships connecting these ports.

In Turkish waters, the general cargo ship ALVAN (IMO 9165798) has been loitering near Tenedos Island, near the entrance to the Turkish Straits, since 23 October. The vessel remains likely to transit the Turkish Straits toward a Russian port, though its departure is likely delayed awaiting more favorable security conditions amid ongoing drone strike risks in the Black Sea.

In the Malacca Strait, the Iranian-flagged container ship VELON 1 (9122473) transited south toward the Singapore Strait, bound for the Malaysian EOPL. ALOR 2 (IMO 9228538) departed the EOPL, transited the Singapore Strait, and anchored in the vicinity of Port Dickson, Malaysia. Meanwhile, NADIA (IMO 9122461) pulled into Port Klang for cargo operations.

At Zhuhai, China, the container ship FLORA (IMO 9349576) departed and sailed for Shanghai via the Taiwan Strait. Meanwhile, ARTENOS (IMO 9283021) departed the anchorage, where it has been loitering since September 10, and headed for the Malaysian EOPL. ABYAN (IMO 9349667) arrived from Shanghai and anchored at the Zhuhai anchorage.

At Shanghai, the container ship SHABDIS (IMO 9349588) departed and sailed via the Taiwan Strait for the Suez Canal, although it may stop at the Malaysian EOPL. TAVA 4 (IMO 9292151) entered the Shanghai terminal for cargo ops. FLORA (IMO 9349576) is enroute from Zhuhai to Shanghai via the Taiwan Strait, with an estimated arrival of November 4.

Meanwhile, AYSAN (IMO 9165803) transited Tsushima Strait into the Sea of Japan (or East Sea) on its way to Vladivostok, Russia, with an estimated arrival of November 3. However, its AIS was no longer received once it passed Ulleuengdo Island.
