Ships Evade Hormuz 'Dark Voyages' Amidst Tensions

Amid escalating tensions between the United States and Iran, some commercial vessels are undertaking perilous 'dark voyages' through the Strait of Hormuz, a critical chokepoint for global oil and gas transport. These ships are disabling their Automatic Identification System (AIS) to reduce the risk of attack from Iranian forces.

The practice of turning off AIS makes vessels virtually invisible to standard radar tracking, necessitating highly experienced navigators to guide them through the waters. Reports suggest that the U.S. military is actively involved, providing guidance to these ships on the optimal times to go dark and strategies for responding to potential threats. This covert navigation is a stark indicator of the heightened security concerns in the region.

Compared to the pre-war era, when over 100 vessels transited the strait daily, current 통항 (transit) volumes remain significantly diminished. The elevated risk has also led to a dramatic increase in insurance premiums. War risk insurance now costs between 2.5% and 4% of a vessel's value, a tenfold to sixteenfold increase from the usual 0.25%.

Beyond insurance, shipping companies face additional costs, including crew wages and war risk bonuses, as they seek to expedite passage through the contested waters. The ongoing issue of passage through the Strait of Hormuz remains a central point of contention in potential U.S.-Iran peace negotiations. While the U.S. advocates for freedom of navigation under international law, Iran insists on its 'sovereign right' to collect tolls. In response to Iran's actions, the U.S. Treasury Department has placed sanctions on the Persian Gulf Security Administration (PGSA), an entity established by Iran to manage passage through the strait.
