Iran Loads East of Hormuz: A New Export Node, a Live Toll Regime, and U.S. Enforcement at Sea

Iran has strategically activated the Kuh Mubarak offshore loading buoy in the Gulf of Oman, transforming the region into a critical export node. Since December 2025, this terminal has facilitated the transit of approximately 6.9 million barrels of Iranian Heavy crude, marking a significant shift in regional trade dynamics. This surge in activity, occurring east of the Strait of Hormuz, has intensified U.S. maritime enforcement efforts, requiring merchant vessels to navigate heightened geopolitical risks while maintaining strict compliance with international sanctions regimes.

Operational compliance remains paramount under the International Ship and Port Facility Security (ISPS) Code, specifically Part A, Section 16, regarding the master’s overriding authority to maintain safety. Furthermore, vessels must adhere to SOLAS Chapter XI-2, ensuring rigorous security assessments and updated ship security plans when operating near volatile export nodes. Compliance departments must monitor the potential for illicit ship-to-ship transfers, as non-adherence to these international mandates could lead to severe detention, insurance policy invalidation, or blacklisting under the latest U.S. Treasury Department enforcement directives.

Masters and navigating officers must exercise extreme vigilance when operating in the Gulf of Oman. These ranks are tasked with maintaining precise AIS data integrity and conducting thorough risk assessments before approaching the Kuh Mubarak buoy. It is essential for bridge teams to monitor U.S. naval broadcasts and maintain a heightened lookout for unauthorized vessels, ensuring that all navigational decisions prioritize crew safety and regulatory compliance amidst the evolving enforcement landscape in these contested waters.
