Strait of Hormuz carries more than oil, handling 20% of global data flows

The Strait of Hormuz, a critical maritime chokepoint, is facing renewed scrutiny as a vulnerability for global internet infrastructure. Recent reports from Yardeni Research highlight that 20% of global data flows rely on undersea fiber-optic cables traversing this narrow passage. With Iran suggesting potential fees on infrastructure, concerns are mounting regarding the security of these subsea assets. For merchant vessels transiting near the Port of Bandar Abbas or the UAE coastline, the risk of accidental cable damage remains a significant operational concern.

Under SOLAS Chapter V, Regulation 34, masters are mandated to ensure safe navigation and maintain a comprehensive passage plan that accounts for all navigational hazards, including subsea infrastructure. While MARPOL Annex I focuses on oil pollution, the protection of critical subsea cables falls under broader international maritime law and UNCLOS provisions regarding the laying and maintenance of submarine cables. Compliance departments must monitor these geopolitical tensions closely, as any disruption to these cables could trigger new regional security protocols or mandatory reporting requirements for commercial shipping.

Navigating officers and masters must exercise extreme caution when anchoring or conducting subsea operations in proximity to identified cable routes in the Strait of Hormuz. It is essential to strictly adhere to designated anchorage areas and avoid emergency anchoring unless absolutely necessary to prevent costly damage to fiber-optic infrastructure. Maintaining precise electronic chart displays and monitoring regional Notices to Mariners is vital for ensuring compliance and avoiding potential legal liabilities during transit through these sensitive waters.
