Quarter of Big Oil Tankers Trapped by Iran War Have Escaped

Approximately one-quarter of non-Iranian large oil tankers, including VLCCs and Suezmax vessels trapped in the Persian Gulf since the onset of the Iran conflict, have successfully exited the region in a stealthy, calculated maneuver. Navigating through high-risk zones near the Strait of Hormuz, these ships have moved away from major terminals like Kharg Island and Ras Tanura. This slow trickle of tonnage highlights the ongoing volatility for merchant shipping operations as companies attempt to reposition fleets amidst escalating regional instability.

The operational movement of these tankers remains strictly governed by SOLAS Chapter XI-2, which mandates the International Ship and Port Facility Security (ISPS) Code for vessels operating in high-risk areas. Compliance departments must ensure that Ship Security Plans (SSPs) are rigorously updated to reflect current threat assessments. Furthermore, adherence to MARPOL Annex I regarding oil spill prevention remains critical during these high-stakes transits. Classification societies and flag states require documented evidence of security drills and bridge team management to maintain valid certification during these sensitive maritime maneuvers.

Masters and navigating officers bear the primary responsibility for executing these high-risk transits. These officers must prioritize continuous radar watch, AIS management protocols, and strict adherence to BMP5 guidelines to mitigate piracy and conflict-related threats. It is essential for bridge teams to maintain heightened situational awareness and ensure that all security communication equipment is fully operational. Understanding the legal implications of transit through contested waters is vital for protecting both the crew and the vessel’s insurance standing.
