Suspicions raised by a Brazilian researcher that the 300,000-dwt tanker Voyager I (built 2003) could have been the cause of a huge oil spill still washing up on the country’s shores proved unfounded.

Humberto Barbosa, coordinator of the Satellite Image Processing and Analysis Laboratory (Lapis) at the Federal University of Alagoas, had identified the NGM Energy-managed vessel as a possible culprit for the incident, in a 21 November public hearing in Brazil.
