This article aims to identify national and international studies and practical experiences in the economic analysis related to subsea decommissioning, in order to identify the best alternatives applied to the Brazilian case. Since the country has a schedule of offshore structures to be decommissioned in the coming decades, studies are needed to support public policymakers by proposing sustainable strategies in line with international standards and practices. To this end, the methodology initially used a literature review based on bibliometric analysis, using scientific publications available on the Scopus and Web of Science databases. Lastly, the article highlights the importance of the multi-criteria analysis to define decommissioning alternatives considering not only economic results, but other perspectives, such as social, environmental, and waste. As the main results, the research identifies the lack of literature and the sectoral limitations of current best practices worldwide. The main reasons for those limitations are the disparity of projects and technological and regional characteristics, and consequently difficulties for costs measurements and benchmarking; lack of professional capabilities on sustainable subsea decommissioning, limited availability of studies, and fragmented regulatory approach on this matter.
