US to Convert Sanctioned Oil Tankers Into Legal Shipping Fleet, Energy Secretary Says

The US plan is to move selected tankers from the sanctioned “dark fleet” into legitimate commercial service. Investors would purchase idle vessels, refurbish them, and use them to carry oil that is not subject to sanctions. The goal is to increase global crude-shipping capacity during a supply and logistics squeeze.

Energy Secretary Chris Wright said the government is creating an approval process for the vessels. This is not, he said, a simple removal of sanctions. The ships would receive legitimate status only after being converted for lawful operations, and they would no longer carry sanctioned oil.

The proposal could add dozens or even hundreds of tankers to the legal market. That matters because the war in Iran and the effective closure of the Strait of Hormuz have raised shipping costs and risks. The plan is still an initiative, so its final scale and effect remain uncertain.

A “dark fleet” or “shadow fleet” is the article’s term for sanctioned oil tankers operating outside the legitimate commercial shipping pool. These vessels are linked to the movement of sanctioned oil, including Russian or Iranian oil, and are not treated as ordinary lawful carriers in the global market.

The article gives a striking estimate: the sanctioned fleet contains about 1,600 vessels. Some are idle, and the administration is discussing whether investors can buy and refurbish selected ships. Those vessels would then receive legitimate status through a government approval process.

The fleet matters because oil shipping capacity is already tight. More than 40% of the world’s roughly 850 very large crude carriers are in or near the Persian Gulf. Converting some shadow-fleet ships could therefore expand legal capacity, although the article does not specify exactly how many would qualify.

The potential addition is large but not precisely fixed. Energy Secretary Chris Wright said converting some of the roughly 1,600 sanctioned tankers could add dozens or even hundreds of vessels to the legitimate crude-shipping market. The article does not say how many ships would ultimately qualify.

The proposed mechanism is selective conversion. Investors would buy idle sanctioned tankers, refurbish them, and seek approval for legitimate status. The ships would then transport oil that is not subject to sanctions. Wright emphasized that this would not simply remove sanctions from the vessels.

The possible impact is significant because available shipping capacity is already under pressure. More than 40% of approximately 850 very large crude carriers are in the Persian Gulf or nearby. Adding even dozens of approved tankers could ease the shortage, while hundreds would represent a much larger expansion.

The war in Iran and the effective closure of the Strait of Hormuz have disrupted a critical route for global energy supplies. Tankers face greater uncertainty and risk when moving oil from the Persian Gulf, where much of the world’s crude shipping activity is concentrated.

The article gives a clear example of the impact. Shipping oil from the Persian Gulf to East Asia now costs more than six times as much as before the conflict, according to Bloomberg. Signal Ocean also reported that more than 40% of approximately 850 very large crude carriers were in the Persian Gulf or within a few days’ sailing distance.

That concentration leaves fewer vessels readily available elsewhere. The result is a tighter market, higher costs, and greater exposure to disruption. The article does not specify a single alternative route, but it shows that the conflict has made oil transport both more expensive and more difficult.

Adding approved tankers would enlarge the pool of vessels available to transport crude legally. More capacity could help balance a market strained by the conflict, the effective closure of the Strait of Hormuz, and the concentration of many ships near the Persian Gulf.

The key mechanism is competition for shipping space. If dozens or hundreds of converted tankers join the legitimate fleet, oil companies may have more vessel choices. That could reduce the premium for scarce tankers and lower transportation costs. The article reports that Persian Gulf-to-East Asia shipping already costs more than six times its previous level.

Lower shipping costs could reduce some pressure on gasoline and diesel prices, which rose after the Middle East conflict escalated. However, the article does not promise cheaper fuel. Oil prices, supply disruptions, and the security situation would still influence what consumers pay.

The article links the sanctions to vessels previously used to transport Russian or Iranian oil. These ships are described as part of the “bad-guy fleet,” or dark fleet, rather than the legitimate commercial fleet. The sanctions therefore restrict their accepted role in lawful oil shipping.

Under the proposed process, investors would buy idle vessels and refurbish them. The US government would then review them through an approval process and give qualifying ships legitimate status. Wright said this is a conversion, not the removal of sanctions from ships that remain in their former role.

The central operating condition is clear: converted vessels would not carry sanctioned oil anymore. The article does not list every technical or legal requirement for approval. It does say that the ships must be converted to legitimate tankers and used to transport oil outside the sanctions regime.

A crude-oil tanker is a large ship designed to transport unrefined petroleum in bulk. Its specialized tanks, pumping systems, and cargo arrangements allow it to move far more oil than ordinary commercial vessels. Sea transport is therefore central when crude must travel between distant producing and consuming regions.

The article highlights the scale of these ships by referring to about 850 very large crude carriers worldwide. More than 40% were in the Persian Gulf or within a few days’ sailing distance. Their concentration shows how heavily global oil transport depends on a limited number of very large vessels.

Strategic routes matter because they connect major oil supply areas with customers. The Strait of Hormuz is described as critical for global energy supplies. When its effective closure disrupts traffic, ships face higher risks and costs, and fewer vessels remain available for other routes. The article reports costs to East Asia exceeding six times previous levels.
