The US blockade has forced Iran to take extreme measures to continue extracting oil.

Due to the US blockade of Iranian ports, Iran is unable to ship oil to its customers, and empty tankers cannot dock to load cargo, leading to a continuous accumulation of its oil reserves. To avoid the shutdown of some oil fields, 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 not previously used to save storage space. These officials stated that Iranian authorities are using containers and "makeshift storage facilities," namely, using dilapidated and abandoned storage tanks in the southern oil hubs of Ahvaz and Asaluyeh to store oil.
