Accident and Leak Prevention In our activities, we produce and move large volumes of oil and its derivatives, for this reason, proper management of processes and activities is essential to prevent loss of containment and leaks that can result in impacts to the environment and people. The leak response plans are structured at the local, regional and corporate levels. The corporate contingency plan provides the structure and information for making additional resources available to the units' Emergency Response Plans, in Brazil and abroad. These additional resources are distributed in the Environmental Defense Centers (CDAs) and in advanced bases, located throughout Brazil, in addition to Transpetro's Emergency Response Centers. In addition to the structure of the CDA System, we are members of Oil Spill Response Limited (OSRL), a specialized oil spill emergency response institution that provides support with resources for complementary action in there is a need for a national or international response (Tier 3) with use of capping, aircraft for the application of dispersants, and chemical dispersants for source control in underwater well blowout scenarios. Through our research center (Cenpes), we maintain permanent research in the field of chemical dispersant application, environmental monitoring, environmental impact assessment, ecotoxicity, modeling, and behavior characterization of oil at sea. Additionally, the contingency equipment park has been continuously updated with the incorporation of more efficient devices, both for land and coastal use, as well as for offshore use. Finally, international partnerships were signed in order to allow access to cutting edge equipment and resources.
Oil and oil product spills The volume of oil and derivatives leaked recorded in 2021 was 11.6 m³, below the alert limit of 120 m³ established internally for the year. This result represents the best performance in the historical series. Of the leaked volume, 1.56 m3 were recovered. This value corresponds to a total of 10 leaks with a volume greater than one barrel (0.159 m³). Of note are the leaks of 6.8 m³ of lubricating oil in the Roncador field, and 1.2 m³ of diesel oil in the Marlim Leste field, accounting for 69% of the total volume leaked in the year. The other eight leaks recorded were less than 1m³. Of the leaks recorded above a barrel, no occurrence was recorded that reached a sensitive coastal area or unusual sensitive area. 2021 was marked by important results in the fight against clandestine derivations, which are characterized by the action of organized crime that pierces the ducts and installs mechanical systems to steal products, posing a risk to life and the environment. In 2021, the set of actions implemented resulted in a reduction in the number of clandestine derivations from 201 to 102, that is, a reduction of 49.25% in the number of occurrences, when compared to the previous year. This reduction occurred consistently in nine of the 10 pipelines most susceptible to this type of occurrence.
