Inside Iran’s Expanding Hormuz Transit System: Checkpoints, Diplomatic Deals and Passage Fees

Navigating the Strait of Hormuz has become increasingly complex as Iranian authorities enforce a rigid transit system, compelling tanker crews to follow designated coastal routes and pass through mandatory island checkpoints. Recent reports indicate that vessels are being pressured to adhere to these specific corridors, often involving the payment of unofficial passage fees. For merchant navy officers, this evolving maritime landscape requires heightened vigilance, as the geopolitical tension surrounding these transit protocols directly impacts the safety and operational security of international shipping lanes.

These transit requirements intersect with critical international maritime regulations, specifically the IMO Convention on the International Regulations for Preventing Collisions at Sea (COLREGs) and SOLAS Chapter V regarding navigational safety. Compliance departments must ensure that bridge teams remain aware of how these local mandates interact with UNCLOS provisions on transit passage. Furthermore, adherence to ISM Code requirements for risk assessment is paramount, as deviation from established safety management systems to accommodate local checkpoint demands could jeopardize insurance coverage and violate MARPOL Annex I environmental protection standards during high-risk maneuvers.

Masters and navigating officers must prioritize bridge resource management when operating in these contested waters. It is essential to maintain detailed logs of all communication with Iranian authorities and document any demands for passage fees to support potential insurance claims. Navigating officers should conduct thorough pre-arrival briefings, ensuring the entire bridge team is prepared for sudden course alterations or unexpected checkpoint inspections. Maintaining strict adherence to company security protocols remains the primary defense against operational disruptions in the region.
