NextFin News - Abu Dhabi National Oil Co. (Adnoc) is continuing to load liquefied natural gas onto tankers that have disabled their satellite tracking transponders in the Persian Gulf, a maneuver typically reserved for sanctioned regimes but now appearing in the mainstream energy trade. According to ship-tracking data and industry officials, at least three vessels have "gone dark" this week while loading at the Das Island terminal, effectively masking their movements as they navigate the increasingly volatile waters of the Middle East.
The practice of turning off Automatic Identification Systems (AIS) has historically been a hallmark of the "shadow fleet" used by Iran and Russia to bypass Western sanctions. However, Adnoc’s adoption of these tactics reflects a pragmatic, if controversial, response to the heightened security risks in the Strait of Hormuz. By obscuring the real-time location of high-value LNG cargoes, the state-owned producer aims to protect its assets from potential seizure or drone attacks, even as it risks drawing scrutiny from international maritime regulators.
Stephen Stapczynski, a veteran energy reporter at Bloomberg who has long tracked global gas flows, notes that this shift indicates a fundamental breakdown in the traditional safety protocols of the Persian Gulf. While Adnoc has not officially commented on the transponder outages, the pattern suggests a coordinated effort to maintain export volumes despite the geopolitical friction that has pushed Brent crude to $109.24 per barrel. The move ensures that the United Arab Emirates remains a reliable supplier to Asian and European markets, which are currently paying a premium for supply security.
The economic stakes are significant. Natural gas prices at the Henry Hub were quoted at $2.32 per MMBtu on May 15, but the landed price for LNG in North Asia remains significantly higher due to freight and insurance premiums. For Adnoc, the ability to move these cargoes without interruption is vital for its multi-billion dollar expansion plans. However, the use of "dark" tankers complicates the task for maritime insurers and the U.S. Navy’s 5th Fleet, which relies on AIS data to monitor traffic and provide security in the region.
Critics of the practice argue that it sets a dangerous precedent for transparency in the global energy trade. If a major, Western-aligned producer like Adnoc normalizes the use of AIS-masking, it becomes harder for authorities to distinguish between legitimate commercial activity and illicit trade. Furthermore, the lack of location data increases the risk of maritime collisions in one of the world’s most congested shipping lanes. For now, the priority in Abu Dhabi appears to be the physical security of the cargo over the transparency of the voyage.
The operational shift comes as U.S. President Trump’s administration maintains a policy of "maximum pressure" on regional adversaries, which has inadvertently increased the collateral risk for commercial shipping. While the UAE remains a key strategic ally of the United States, its energy arm is prioritizing the continuity of its export machine. The sight of massive LNG carriers vanishing from digital maps only to reappear days later in the Indian Ocean has become the new, uneasy reality of the Persian Gulf energy trade.
