The incident, which claimed nine lives, occurred following a leak of natural gas on board the Cidade de São Mateus while the FPSO was anchored in the Camarupim oil field. The explosion was said to be the most serious oil and gas incident to occur in Brazil in the past 14 years.

The report of Petrobras was announced on Friday and states that series of technical failures and poor decision making led to the deadly incident. In particular, the report reveals that the main causes of the explosion are the non-compliance with the proper fluid pumping procedures together with a conflicting piece of equipment. Furthermore, there had been no procedural training of the workers prior they were sent to the pump house.

The analysis of Petrobras has already been submitted to several governmental agencies.
