Seafarer missing after missile strike on Greek tanker as Hormuz blacklist hits 239 ships

A seafarer is missing after a missile-suspected strike on a Greek-operated product tanker 50 nautical miles north of Qatar's Madinat ash Shamal, deep inside the Arabian Gulf and well away from the Strait of Hormuz chokepoint itself.

The Marshall Islands-flagged Velos Sapphire, a 74,998 dwt product tanker built in 2007 and managed by Athens-based Velos Tankers, was hit at 23:20 UTC on November 4 according to UK Maritime Trade Operations, which initially reported two unidentified projectiles striking an unnamed tanker. The operator later reported an explosion on the aft port side, believed caused by an unidentified missile. A fire broke out and was extinguished.

The IMO has since identified the vessel and recorded damage, no pollution and one seafarer missing. Maritime security sources say the crew member was killed, though the IMO has not confirmed a fatality.

AIS data tells its own story. The tanker had departed Fujairah on November 3, bound for Sitra in Bahrain. Its speed fell to 2.4 knots shortly before the attack and to roughly 1.1 knots afterwards. It then regained speed and continued towards Bahrain — evidence, most likely, that propulsion survived the blast.

What does this change for Gulf operators?

The location matters. A strike 50nm north of Qatar pushes the threat envelope well beyond Hormuz, where most attacks have clustered. Ships transiting the southern Arabian Gulf, not just the strait's approach lanes, now sit inside the risk zone.

Curiously, the Velos Sapphire does not appear on Iran's blacklist of vessels accused of breaching its transit requirements. A sister ship in the same Greek-managed fleet, the Velos Amber, is listed — but no connection between the blacklist and this attack has been established.

Iran reshuffles the blacklist

Iran's Persian Gulf Strait Authority has meanwhile removed two LPG carriers sanctioned by Washington from its non-compliance list. The 2003-built Gas Marakua and the 2001-built SOGL — both designated by the US Treasury in October over links to Iranian petroleum shipping networks — disappeared from the list published on November 5.

The authority added the Mercan, a 2018-built, Panama-flagged chemical and products tanker owned and operated from Turkey.

The net effect: 239 vessels now sit on Tehran's blacklist, down from 240 earlier in the week but sharply higher than the 77 recorded in September. PGSA offered no explanation for the changes.

The stakes for owners are concrete. The authority has threatened blacklisted vessels with fines, detention or confiscation during future passages, and warned that ships cooperating with designated vessels through ship-to-ship transfers could themselves face restrictions.

Sanctions stacking

The overlapping regimes create a legal trap. Washington has sanctioned PGSA itself and warned that obtaining services or safe-passage guarantees from the Iranian authority can expose shipping companies to sanctions risk. An owner seeking Tehran's clearance to avoid detention may, in doing so, trigger US consequences. There is no clean lane through that gap.

Mines return to the picture

Mine threats have resurfaced. The US has called on Iran to identify mine locations in the Strait of Hormuz during discussions at the IMO. Iranian forces have separately claimed several tanker mine strikes without naming the vessels. Tehran claims incidents involving five tankers and a tugboat, including fires and mine damage; the reports remain independently unverified, and some claims may overlap with previously reported attacks.

A Joint Maritime Information Centre assessment issued Thursday recorded four attacks in the strait over its latest 96-hour reporting period, all concentrated within 52 hours off Oman's Musandam peninsula between November 1 and 3. Two further attacks were recorded inside the Arabian Gulf. JMIC still rates the threat around Hormuz as severe, warning of further deliberate strikes, drone overflights, targeted surveillance and radio harassment of merchant vessels.

Traffic near collapse

The numbers on transits are stark. AIS-based monitoring recorded just nine commercial crossings on Thursday. The seven-day average runs at about nine ships a day — barely a tenth of the pre-conflict level of roughly 85.

South Korea is preparing to respond. Seoul wants to expand its Cheonghae naval unit's operational area towards southern Oman and reinforce it with a P-8A maritime patrol aircraft and mine-countermeasure capabilities. The proposal needs parliamentary approval. It would not place the unit inside Hormuz, but it could support future mine-clearance operations.

Diplomacy is grinding along in parallel. The foreign ministers of Oman and Iran discussed practical and technical arrangements for restoring unhindered navigation through the strait on Thursday. No reopening agreement has been announced.

The IMO's latest tally puts confirmed maritime incidents across the region at 129, with 24 seafarer fatalities since the conflict began. Until either the blacklist stops growing or the talks in Muscat produce an agreement, Gulf operators face the same arithmetic: a tenth of normal traffic, a 239-ship blacklist, and now strikes reaching into the Arabian Gulf itself.
