A crude oil supertanker has been observed moored at Iran's main export terminal for the first time in nearly a month, signaling a potential resumption of loading activity despite a US-led maritime blockade aimed at restricting Tehran's oil exports, according to a Bloomberg analysis on Wednesday.
It said an image captured by the European Union's Sentinel-1 satellite on Tuesday morning showed a vessel matching the dimensions of a very large crude carrier alongside a jetty west of Kharg Island, Iran's principal crude-export facility in the northern Persian Gulf.
No similarly sized tanker had been observed at the island since May 6.
The sharp decline in loading activity in recent weeks suggests Tehran may have exhausted the supply of tankers available to transport its crude under the blockade, which began in mid-April.
Alternatively, Bloomberg said, Iranian authorities may have opted against loading vessels without assurances that cargoes could reach international buyers.
Before the restrictions were imposed, VLCC loadings at Kharg Island occurred almost daily.
Whether the newly arrived tanker will be able to leave the Persian Gulf remains uncertain as the US maintains a blockade of all ships originating from or destined for Iranian ports.
US Central Command said Tuesday that the US Navy had enforced blockade measures against a tanker as it sailed toward Kharg Island through international waters.
According to a social media post, US forces fired a missile into the vessel's engine room.
The US Navy imposed a blockade on maritime traffic entering and leaving Iranian ports on April 13.
Since then, six commercial vessels have been disabled and 122 others redirected, according to CENTCOM.
