AI Article Synopsis
- A mysterious oil spill impacted a large section of the Brazilian coast in 2019-2020, prompting a study to estimate the volume of oil released using the Spill, Transport and Fate Model (STFM).
- The research hypothesizes that the spill was caused by issues like tanker buoyancy problems, leading to a gradual leak of oil from the vessel into the ocean.
- The estimated spill volume ranged from 5,000 to 12,500 cubic meters, suggesting it could be the largest spill in Brazil since 2004, which strained institutional resources and led to socioeconomic challenges.
Article Abstract
In 2019-2020, a mysterious oil spill reached a large part of the Brazilian coast. In order to contribute to the clarification part of these mysteries involving this accident, the present study aims to estimate the initial volume spilled using the STFM (Spill, Transport and Fate Model). We started from the hypothesis that the leak was caused by tanker buoyancy problems (hull rupture or engine failure), resulting in slow loss of part of its cargo (leaking or dumping) in the subsurface waters. The estimated volume (5000-12,500 m) was similar to that expected in a continuous leak from an internal compartment tanker with the size between PANAMAX and SUEZMAX. This volume may have been the largest oil spill on the Brazilian coast since 2004, and it caused institutional and socioeconomic crisis because of the poor management of public resources.
