UAE’s ADNOC Sends Another LNG Carrier To India Through Hormuz In ‘Dark Mode’

ADNOC Logistics and Services has reportedly deployed an LNG carrier through the Strait of Hormuz in 'dark mode,' raising concerns regarding maritime security and vessel tracking protocols. The vessel ceased transmitting its Automatic Identification System (AIS) signal on May 2 while positioned near the entrance to the Strait. This tactical maneuver, often associated with bypassing geopolitical scrutiny or sanctions monitoring, highlights the complex operational environment for merchant navy officers navigating high-risk zones while transporting critical energy supplies to Indian ports.

Operating a vessel with a deactivated AIS signal directly contravenes Regulation 19 of SOLAS Chapter V, which mandates the continuous transmission of identification data for safety and security purposes. Compliance departments must recognize that disabling transponders risks severe regulatory penalties, potential loss of P&I insurance coverage, and increased scrutiny from port state control authorities. Furthermore, this practice complicates the duties of maritime security teams and classification societies, as it undermines the transparent monitoring required under international maritime law to ensure safe passage through congested international chokepoints.

For navigating officers and masters, these operational directives present significant professional challenges. Navigating officers must maintain heightened situational awareness and bridge watchkeeping standards when AIS data is unavailable to avoid collision risks. Masters are advised to document all instructions regarding signal deactivation within the official logbook to ensure legal protection. It is critical for these seafarers to prioritize bridge resource management and radar-assisted navigation to maintain safety standards while adhering to sensitive corporate directives in volatile regions.
