Ships and Cargo Wrongfully Confiscated, says Stena. Stena Oil, the Swedish Oil Company, has alleged that the West African republic of São Tomé e Príncipe has wrongfully confiscated two ships chartered by the Swedish oil company Stena Oil, including the cargo. According to Stena, the captains have been severely sentenced to three years of imprisonment and charged with "smuggling" in a show trial. A fine of 5 million EUR has been imposed, and the vessels and cargo have been confiscated by the state of São Tomé. It is Stena Oil's clear and firm position that the allegations are entirely unfounded. Neither the ship owners nor Stena Oil have been given the opportunity by any court to clear the false allegations against them.
