Dark Tankers Over Oman's Cables: What the Tracking Data Shows

On 29 October 2026, the maritime intelligence company Windward published tracking data on sanctioned, Iran-linked vessels near the subsea internet cables off Oman's Batinah coast. It says some of them switched off their location transponders inside the cable corridors off Sohar and Muscat. The report came days after senior Iranian officials publicly threatened Gulf undersea cables. Nothing has been cut, and the data does not prove sabotage. Even so, it puts Oman's internet links to the rest of the world at the centre of a regional security story.

📌 Key Takeaways

• According to Windward's 29 October analysis, a sanctioned Iran-flagged tanker stopped broadcasting its position for 86 hours inside the 2Africa and Bay of Bengal Gateway cable corridors off Sohar, starting 15 October.
• A second sanctioned vessel, a gas carrier, slowed inside the 2Africa corridor, turned back off Muscat and stopped broadcasting about 2 nautical miles from the AAE-1 cable. As of 28 October it had been dark for five days.
• Windward counts seven cable systems in the corridors where these ships operated off the Batinah coast, including 2Africa, AAE-1 and the Oman Australia Cable.
• The activity overlapped with Iranian threats against Gulf cables on 12, 19, 21 and 23 October, including a Reuters report that Tehran has "detailed plans" to hit them if war resumes.
• Windward says it has not established whether any cable mapping took place. We found no public statement from Omani authorities or operators on the activity.

🛰️ What the New Tracking Data Shows

Windward covered vessel activity from 5 to 28 October 2026. Its report was published on 29 October and draws on Windward's own AIS (Automatic Identification System) records and Vortexa cargo data. Three movements happened close to the Omani coast:

• CELESTIAL SEA, off Sohar and Shinas: Windward says this sanctioned, Iran-flagged products tanker was travelling empty. On 14 and 15 October it drifted in a loop for 4.3 hours about 0.65 nautical miles from the 2Africa corridor. On 15 October it went dark inside the 2Africa and BBG corridors off Sohar for 86 hours. It reappeared about 9 nautical miles away, made a U-turn above BBG on 19 October and then anchored off Shinas.
• A sanctioned gas carrier, off Muscat: On 23 October it left Shinas for Malaysia carrying about 494,500 barrels of LPG. Ten hours later, Windward says, it slowed below 3 knots for 42 minutes inside the 2Africa corridor, turned about 180 degrees back toward Oman and went dark about 2 nautical miles from AAE-1.
• Seven systems in the corridor: According to the same report, the corridors where the tankers operated carry 2Africa, Bay of Bengal Gateway, Asia Africa Europe-1, the Oman Australia Cable, Europe India Gateway, Transworld and SeaMeWe-4.

The report also describes two other vessels operating on the Iranian side, between Jask and Chabahar. Those movements were not near the Omani coast.

🔁 An earlier drift off Muscat

The 29 October report follows an earlier Windward analysis dated 26 October. That analysis describes a tanker that was sanctioned by the US in September 2024. On 30 September it slowed below one knot over the cable corridors off Muscat and drifted for 73 hours. Its track crossed the edges of the AAE-1, BBG and 2Africa corridors and came within half a nautical mile of FALCON, GBI and MENA. Windward says the ship changed its MMSI, call sign and flag code four days before the drift, and that satellite imagery confirmed its position on 1 October. SAFETY4SEA reported the same findings and noted Windward's caveat: none of the activity could be confirmed as "a surveying operation or preparation for sabotage."

⚠️ The Threats Behind the Timing

The vessel activity coincided with a series of Iranian statements about Gulf cables:

• 12 October: Windward says Iran's security chief Mohsen Rezaei warned that cables and data centres across the region could be attacked if the war resumes.
• 19 October: IRGC spokesman Hossein Mohebbi referred to "seven major internet cables" under the Strait of Hormuz, according to Windward.
• 21 October: Iran International reported that IRGC official Yadollah Javani warned the Hormuz cables could be targeted if Iranian infrastructure came under attack.
• 23 to 24 October: In a Reuters report republished by The Daily Star, two senior Iranian security officials said Tehran had detailed plans to target Gulf undersea cables if the US and Israel attacked again. One said Gulf states "should hold Washington, not Tehran, responsible for any damage."

Some propaganda has added to the noise. CircleID noted on 28 October that a widely shared video of simulated cable attacks has not been independently traced to an official source. It also said the video is not evidence of any actual attack.

🇴🇲 Why Oman Is at the Centre of the Map

Geography explains why Oman keeps appearing in this story. Iran International, citing TeleGeography, reported that the submarine cables crossing the Strait of Hormuz run through Omani waters, partly because of long-standing political tensions with Iran. Windward's 26 October count found these Omani landings:

Those southern landings give the Sultanate an advantage that some of its neighbours lack. Windward says Iraq, Kuwait, Bahrain and Qatar are the most exposed because every cable they use lands inside the Gulf. SAFETY4SEA likewise noted that Oman has alternative subsea connections outside the Strait. Oman also has a direct cable link to Iran: according to CircleID, the OMRAN/EPEG system connects the two countries, so damaging it would also hurt Iran's own connectivity.

🔍 What the Data Does Not Prove

It is important to be clear about the limits of this evidence:

• Movement is not intent. Windward's own 26 October analysis says tracking shows where a ship goes, not what it does on the seabed. It also says that whether any mapping took place "is not established."
• Single-source data. The analysis comes from a commercial maritime intelligence vendor using its own platform. Other outlets have repeated it, but we found no independent verification.
• Limited global impact. TeleGeography's Alan Mauldin told Reuters that less than 1% of international bandwidth passes through the Strait of Hormuz. For Gulf countries themselves, however, the regional impact could be much larger.

Saremifar also told Iran International that earlier IRGC cable threats were largely rhetorical. He said evidence of actual naval movements toward the cables would justify a different assessment. That is exactly the kind of evidence Windward now claims to show, which is why the 29 October report deserves attention even though its findings are not confirmed.

🏗️ The Practical Stakes for Oman's Networks

Oman's international connectivity has been growing quickly. Mobile, fibre and international bandwidth figures in our look at Oman's latest telecom numbers show how much daily life and business now depend on that capacity. The Sultanate is also promoting itself as a home for large AI data centres, which need fast, resilient international links. If a stretch of cables off the Batinah coast became a security concern, it would affect:

• Operators and cable consortia, who may need to review spare capacity and rerouting plans through Salalah and the overland links.
• Data centre investors, for whom route diversity and repair times are basic due-diligence questions.
• Government and banking services, which depend on international connectivity for cloud services, payments and content delivery.

As of publication, we found no public statement from the Telecommunications Regulatory Authority, the Maritime Security Centre or Oman's operators about the reported vessel activity.

🇴🇲 Why this matters for Oman

Under Vision 2040, Oman is presenting itself as a safe, neutral and well-connected digital hub, and the cables along its coast are a large part of that case. The Windward data does not show that any cable was touched. It does show that sanctioned ships have been spending unusual amounts of time over Oman's cable corridors while Iranian officials talk openly about targeting them. Oman's southern landings at Salalah and Qalhat give it more route diversity than most of its Gulf neighbours. Using that advantage well, and being open about how resilient the country's connectivity is, will matter for the investors and AI campuses Oman is trying to attract. It will matter just as much for the residents and businesses who depend on those cables every day.
