巴西海上油田设施弃置的探索实践与经验借鉴OACHSSCD

In recent years,the development of Brazil's deepwater and ultra-deepwater oil and gas resources has continued to progress.Consequently,a growing number of offshore facilities are entering the mid-to-late stages of their operational lifecycles,driving increasing demand for decommissioning and giving rise to a substantial decommissioning market.Brazil has established a multi-agency regulatory framework involving the National Agency for Petroleum,Natural Gas,and Biofuels(ANP),the Brazilian Institute of Environment and Renewable Natural Resources(IBAMA),and the Navy,which are responsible for developing technical standards,conducting environmental licensing,and overseeing maritime safety respectively.Brazil's experience shows that offshore decommissioning is not merely an end-of-life activity,but rather a critical source of risk that requires systematic planning and management throughout the entire lifecycle.A robust regulatory framework,effective interagency coordination mechanisms,and science-based engineering management are essential to ensuring the safety,environmental sustainability,and economic viability of decommissioning operations.Through its explore in institutional design,risk governance,and green decommissioning approaches,Brazil has gradually developed a distinctive"Brazilian Deepwater Decommissioning Management Model",which offers valuable insights for the decommissioning of offshore oil and gas facilities worldwide.
