Several Venezuelan oil tankers that attempted to evade a strict U.S. maritime blockade by sailing in “dark mode” - with tracking systems switched off - have now turned back and returned to Venezuelan waters. The retreat follows heightened U.S. enforcement targeting sanctioned vessels carrying crude and fuel. Some ships were intercepted, one seized, and others forced to reverse course after weeks of cat-and-mouse at sea. The developments underscore the growing pressure on Venezuela’s oil exports as Washington tightens its grip on sanctioned shipping routes, even as talks continue over possible licensed crude exports under U.S. supervision.
