Kharg Stalls as Iran Expands Maritime Control Across Hormuz

Between May 11 and May 13, the Strait of Hormuz faced significant operational constraints as Iranian export infrastructure, including the Kharg Island terminal, operated well below standard capacity. Reports indicate a surge in dark tanker staging within protected Iranian waters, accompanied by intensified maritime activity linked to the IRGC. These developments have complicated navigation through this critical chokepoint, forcing commercial vessels to reassess transit security protocols while navigating the heightened geopolitical tensions impacting regional maritime trade routes and energy exports.

The ongoing instability in the Strait of Hormuz necessitates strict adherence to the ISPS Code, specifically Part A, Section 4, regarding maritime security levels. Compliance departments must ensure that vessel security plans are updated to reflect current regional risks, aligning with SOLAS Chapter XI-2 requirements. Furthermore, masters must remain vigilant regarding MARPOL Annex I regulations during potential emergency maneuvers or forced deviations. Failure to maintain rigorous documentation and security drills during these high-risk transits could lead to severe regulatory scrutiny and insurance complications for shipowners.

Masters and navigating officers must exercise extreme caution when transiting the Strait of Hormuz, prioritizing bridge team management and maintaining a heightened lookout for unidentified vessels. It is essential to verify AIS data integrity and report any suspicious activity to the United Kingdom Maritime Trade Operations (UKMTO) immediately. Navigating officers should review contingency plans for potential vessel detentions or restricted maneuvering scenarios to ensure the safety of the crew and the integrity of the vessel during these volatile operations.
