Abstract

Decommissioning of ageing installations continues to be a crucial concern for the offshore oil and gas industry. Within the next decade, it is anticipated that several structures will be required to undergo the decommissioning process. With the removal of these installations comes the management of waste materials in line with current regulations. Prior to the reuse, recycling, or disposal of any materials, they must be decontaminated from hazardous waste. This paper builds on previous research, which identified the knowledge of current decommissioning legislation as one of the critical issues. Expert judgements have been analysed using an analytical hierarchy process. This, in turn, has been used to refine a Bayesian network to further determine the key factors in the decommissioning process.
