ABSTRACT
Decommissioning of oil and gas offshore facilities is employed at the end of the life cycle of the field in compliance with national legislation, international laws and standards. The installation of oil and gas platforms keeps increasing worldwide necessitating the development of an innovative approach that determine the potential decommissioning option with least environmental impact and cost. This paper introduces an approach assessing financial and non-financial criteria of each decommissioning option by which financial analysis is assessed using net present value evaluation while non-financial factors are assessed through weighted evaluation technique. The economic analysis of removal option is considered inadequate in identifying the appropriate decommissioning option, so the assessment of the feasibility of environmental, health and safety, and public outcomes will be directive towards the best removal option with the lowest financial and environmental impacts combined.
