As the ongoing conflict in the Middle East tightens pressure on global energy supply routes, oil giants from the United Arab Emirates (UAE) and Qatar are turning to unconventional shipping tactics to move their oil and gas out of the Persian Gulf to nations in need of energy. The Abu Dhabi National Oil Company (Adnoc) is navigating one of the world's most sensitive maritime corridors, the Strait of Hormuz, where Iranian forces and US naval patrols operate in close proximity amid escalating regional tensions.
What Are Dark Transits?
According to ship-tracking data and people familiar with the matter cited by Bloomberg, the UAE state energy firm has relied on so-called 'dark transits.' These are journeys in which vessels switch off transponders while passing through the Strait of Hormuz, allowing tankers to avoid real-time detection. The tactic has so far helped maintain export flows during periods of geopolitical risk.
Adnoc's Fleet Strategy
Unlike many regional producers and commodity traders that depend on chartered vessels, Adnoc has leaned on its own controlled fleet, including ships operated through Navig8, majority-owned by its shipping and logistics arm, and its joint venture with Wanhua Chemical Group. The fleet includes crude carriers, refined product tankers, and gas transport vessels, giving the company greater operational flexibility. Industry sources say this structure has allowed Adnoc to sustain relatively efficient cargo movements even as others face constraints linked to shipowners' risk appetite.
Qatar's Exports and LNG Movements
Qatar has also continued exports through the Strait of Hormuz, highlighting a broader pattern of Gulf producers adapting to volatile conditions in one of the world's most critical energy corridors. One LNG tanker, Al Rayyan, was recently tracked north of Muscat after passing through the strait, en route to China, though it had briefly stopped transmitting near Qatar's Ras Laffan facility earlier in the month, according to vessel data. Such intermittent signal loss has become more common as ships adopt stealth navigation practices.
Shuttle Runs and Ship-to-Ship Transfers
Adnoc's strategy also includes short-cycle 'shuttle runs,' where vessels quickly return after deliveries to reload cargoes, helping maximize throughput from terminals such as Zirku Island and the Ruwais refinery complex. Ship-to-ship transfers are also reportedly conducted in safer waters near Fujairah or Sohar, or onward toward India's west coast.
LNG Inflows and Discreet Movements
For LNG operations, similar discreet movements have been observed. Tankers are said to approach the Strait near Fujairah before disabling tracking systems en route to Das Island, Adnoc's key export hub inside the Gulf. Satellite imagery suggests continued activity at the facility, despite limited broadcast data from vessels.
Analyst Insights and Implications
Analysts cited by Bloomberg said that the approach reflects both strategic urgency and logistical necessity, as storage constraints and geopolitical uncertainty push producers to keep exports moving. However, the scale of such shipments remains below pre-conflict levels, particularly in LNG trade, where only a handful of crossings have been confirmed in recent months compared with normal daily flows.
The reliance on low-visibility navigation also complicates verification of cargo routes, with vessels potentially choosing alternative corridors or passing through Iran-influenced waters where informal arrangements may apply. Despite this opacity, the pattern highlights how producers are adapting to keep critical energy supplies flowing through the Strait of Hormuz, even as diplomatic negotiations continue to shape the broader security outlook in the region.
