The United States just made a major move in its battle against oil smuggling. Just this week, they seized the Skipper, an old and decaying oil tanker previously called the M/T Adisa, associated with trips to nations under U.S. sanctions. In the stunning operation on Wednesday, U.S. commandos seized the ship near the coast of Venezuela. This effort marks a re-focused effort to obliterate a sprawling web of shadowy seafaring operations that have enabled nations such as Iran and Russia to elude sanctions.
In November 2022, the U.S. imposed sanctions on The Skipper. Authorities accused the ship of carrying crude oil to Iran’s Revolutionary Guard and to the militant group Hezbollah, which operates in Lebanon. This particular tanker has been linked to the transport of other illicit cargoes, including from Russia and Iran, making the already-complex geopolitical tableau even worse.
At the time of its seizure, the Skipper was loaded with more than 2 million barrels of heavy crude oil. According to reporting from the Miami Herald, approximately half of this crude oil was derived from a state-run Cuban oil importer. This enforcement action illuminates the complex web of international trade that rarely plays by the rules.
The Skipper went to extensive lengths to cover his track. It altered its precision tracking signals in order to fake the appearance that it was plotting a course off the coast of Guyana. U.S. forces intercepted it far further afield than its intended destination, indicating just how far the vessel went to hide its true practices. According to Guyanese authorities, the Skipper has been flying a fake Guyanese flag. This move makes the ship stateless under international maritime law, leaving it more susceptible to interception by U.S. officials.
The Capitana Skipper, one of an estimated 30 sanctioned tankers currently working in the waters off Venezuela’s coast. Many of these vessels are equally as vulnerable, as they instead carry bogus registrations. This seizure was more significant than the loss of a single vessel. It would be a much-needed watershed moment in America’s efforts to stop illicit vessels that export oil for sanctioned regimes.
Claire Jungman, an expert on maritime law and sanctions, remarked on the broader implications of this operation, stating, “The cost of doing business with Venezuela just went way up.” She further noted, “These are very risk-tolerant operators, but even they don’t want to lose a hull. A physical seizure is an entirely different category of risk than falsifying paperwork and bank fines.”
Michelle Weise Bockmann, a maritime analyst, emphasized the significance of this development, highlighting that “there are hundreds of flagless, stateless tankers that have been a lifeline for revenues” for regimes such as those led by Maduro in Venezuela, Iran, and Russia. She added, “They can no longer operate unchallenged.”
It is an indication of a new phase in U.S. policy. These recently-invented tactics focus on oil smuggling networks. Francisco Monaldi, an energy expert, cautioned against jumping to conclusions about the long-term impact of this operation, saying, “It depends if this is just a one-off event or something more systematic.”
