Offshore platform decommissioning is an essential stage in the lifecycle of oil and gas assets, driven by the maturity of the production curve and the need for sustainable practices. This article presents the methodological approach for planning decommissioning projects, with a focus on efficiency, safety, and environmental responsibility. The methodology was based on documentary analysis, regulatory review, and collaborative workshops with multidisciplinary teams. The use of the Product Flow Diagram (DFP), Product Descriptions, and the RACI matrix promoted standardisation, traceability, and integration among technical areas. The results indicate gains in clarity of deliverables and general improvements in the Planning Phase, contributing to the execution of safer, more efficient, and environmentally responsible Decommissioning Projects.
