In the Caribbean Sea, the U.S. Coast Guard intercepted the tanker Olina, which was transporting oil. This incident marks the fifth detention of a vessel from the so-called "shadow fleet."

The Olina, a vessel from the "shadow fleet," was taken under control by the U.S. Coast Guard near Venezuelan waters. According to The Wall Street Journal, citing a U.S. official and the maritime security company Vanguard, the tanker left one of Venezuela's ports but then returned to the area. The ship is known for repeatedly changing both its flag and its name. The Olina has drawn attention for transporting Russian oil and violating sanctions restrictions. According to the publication "Novaya-Evropa," the vessel is currently owned by a Hong Kong-based company, whose owner is a Chinese citizen. The Olina's registration number is identical to that of the tanker Minerva M, which the U.S. added to its sanctions list in January 2025 as a "shadow fleet" ship. This incident marks the fifth time Americans have seized a vessel as part of an operation aimed at stopping illegal oil shipments from Venezuela.
