Abstract: The process of oil and gas exploration and production (E&P) in offshore environments has been carried out worldwide for over 70 years, mostly through fixed production platforms. As these structures approach the end of their life cycle, the topic of decommissioning has entered the agenda of several companies, leading to the need for more robust planning and to the generation of new business opportunities. In Brazil alone it is estimated that between 2021 and 2025, the total expenditures in decommissioning will reach $5.2 billion. The formation of this market involves overcoming technical, logistical, environmental, regulatory and project management challenges.Key among them is the establishment of a work breakdown structure (WBS) that organizes and orders the activities that make up the complete scope of the project, contemplates the specificity of Brazilian legislation, and facilitates the identification of service providers related to each step of the process. Based on good project practices and the particularities of the Brazilian legislation, this paper proposes a standard WBS specific to that country, covering the decommissioning process from planning to project closure, including a proposal for a standard contract WBS for engineering, preparation, removal and disposal (EPRD).
