TEHRAN, — May 19, 2026 : Iran’s main crude oil export facility at Kharg Island has recorded no major tanker loading activity for at least ten days, according to recent satellite imagery and maritime tracking data, highlighting the growing operational impact of the ongoing U.S. naval blockade on Iranian oil exports.
Satellite images reviewed in mid-May showed that no large ocean-going crude tankers had been positioned at Kharg Island’s export berths since May 8. The island, located in the northern Persian Gulf, is Iran’s primary crude export hub and historically handles the majority of the country’s seaborne oil shipments through its network of loading jetties designed for very large crude carriers (VLCCs) and other large tankers.
The extended absence of loading operations marks one of the longest interruptions recorded at the facility since the current regional tensions escalated. Maritime monitoring data also showed a buildup of more than 20 empty or waiting vessels anchored near Kharg Island, indicating increasing congestion and delays linked to restrictions on tanker movements in the region.
The disruption follows the U.S. decision on April 13 to impose a naval blockade targeting Iranian ports and oil export routes after escalating regional conflicts and Iran’s efforts to strengthen control over the Strait of Hormuz. U.S. naval assets and Central Command forces have since increased patrols and interdiction operations around the strategic waterway, affecting commercial vessel traffic associated with Iranian crude exports.
With operations at Kharg Island heavily constrained, Iran has shifted part of its export activity to the Jask oil terminal on the Gulf of Oman. The terminal, located east of the Strait of Hormuz, was developed as an alternative export route that allows crude shipments to bypass the narrow strait and reduce dependence on the Persian Gulf export corridor.
Recent satellite imagery identified the sanctioned Aframax tanker Vernon loading crude at the Jask terminal. The vessel was observed moored at one of the terminal’s single buoy mooring systems connected to onshore storage infrastructure and pipeline networks. The use of Jask reflects Iran’s attempt to maintain limited export capability despite increasing restrictions around Kharg Island and the Strait of Hormuz.
Commercial shipping intelligence firms reported that tanker routing patterns linked to Iranian crude exports have changed significantly in recent weeks, with some vessels remaining anchored offshore for extended periods as floating storage. While a limited number of empty tankers have continued operating in the region, the sustained absence of regular crude loadings at Kharg Island suggests mounting pressure on Iran’s export logistics and storage infrastructure.
U.S. Treasury Secretary Scott Bessent recently stated that Washington believes Iran’s oil storage capacity is approaching its limits, arguing that restrictions on tanker access have reduced Iran’s ability to move or store crude exports at sea. Analysts monitoring the situation noted that prolonged disruption at Kharg Island could eventually affect Iran’s crude production levels if export bottlenecks continue.
Kharg Island remains connected to Iran’s broader oil production system through extensive pipeline and storage networks, making it central to the country’s energy export operations. Any sustained interruption at the facility has the potential to reduce overall export volumes and force greater reliance on secondary terminals such as Jask.
No official statement from Iranian authorities regarding the current status of loading operations at Kharg Island had been issued in the latest publicly available reports. Commercial satellite providers and maritime tracking firms continue monitoring tanker positions, anchorage activity, and export movements across the Persian Gulf and Gulf of Oman as additional imagery becomes available.
