Qatar and UAE LNG tankers go dark in Strait of Hormuz to evade security risks

Qatar and United Arab Emirates liquefied natural gas (LNG) tankers are turning off their transponders in the Strait of Hormuz, shifting their logistical strategies in response to ongoing military conflict in the Middle East and the closure of the strategic waterway.

According to a Bloomberg report citing industry sources and vessel-tracking data, as time and patience run thin for both nations, tankers have begun operating under radio silence to conceal their movements and secure their LNG shipments.

The report noted that neither Qatar nor Abu Dhabi, the federal emirate of the UAE, is subject to international sanctions. Despite this, state-owned QatarEnergy and Abu Dhabi National Oil Co. (ADNOC) are employing these “going dark” tactics to minimize security risks for their vessels and crews transiting the Strait of Hormuz.

Vessel-tracking data revealed that in May, at least four Qatari LNG vessels and four tankers linked to Abu Dhabi-based ADNOC transited the Strait of Hormuz without transmitting tracking signals. Sources speaking to Bloomberg stated that Qatari authorities requested captains of state-owned and chartered tankers to turn off their Automatic Identification System (AIS) transponders when navigating around the Ras Laffan port—the world’s largest LNG export terminal—as well as when transiting or exiting the Persian Gulf.

The implemented security measures extend beyond turning off transponders. Sources reported that vessels have been instructed to transit the gulf in pairs to enhance security, and tanker captains who refused to comply with the “shadow” navigation protocols have been replaced.

Industry sources speaking to Bloomberg warned that the increase in covert transits undermines the fundamental rules of international maritime trade and transforms these shipping routes into high-risk areas.

They emphasized that until recently, every cargo in the LNG sector could be tracked in real time, but these newly adopted tactics have eliminated that transparency.

Saul Kavonic, a senior energy analyst at energy consultancy MST Marquee, commented on the situation, saying: “It is entirely natural for Persian Gulf LNG producers to try to avoid Iranian attacks and consequently adopt shadow fleet methods. This could persist as long as Iran continues to control and threaten transits through the Strait of Hormuz. This practice may continue for a long time even after a peace agreement is signed.”

Following the start of US and Israeli attacks on Iran, the Tehran government closed the Strait of Hormuz, a choke point for approximately 20% of global oil shipments and 30% of global liquefied natural gas.

After negotiations in Islamabad failed, US President Donald Trump announced on April 13 that he would impose a blockade on Iranian ports. In late May, he announced that the blockade was lifted as part of the planned peace treaty process with Tehran.
