Svmuu reported that due to the U.S. blockade on Iranian ports, Iran is unable to ship oil to customers, and empty oil tankers are also unable to dock for loading, resulting in a continuous buildup of oil inventories. To prevent some oil fields from shutting down, Iran has begun storing oil on floating tankers. However, according to current and former Iranian officials, the country, which heavily relies on oil exports for most of its revenue, is now adopting methods it has not used before to save storage space. These officials stated that Iranian authorities are using containers and "makeshift storage facilities"—specifically, poorly maintained abandoned storage tanks in the southern oil hubs of Ahvaz and Asaluyeh—to store oil.
