Abstract

Civil engineering projects, including the construction of oil platforms, are inherently associated with various types of risks from different perspectives. Risk management in large-scale water and marine structure projects, such as the construction of oil platforms, is essential due to multiple uncertainties and the extensive environmental and human factors involved. Identifying, assessing, and prioritizing risks are critical steps in managing these projects effectively. This study aims to identify and rank key risks in the construction of an oil platform using fuzzy multi-attribute decision-making models. In this research, risks in the areas of engineering, execution, passive defense, and the environment were identified through literature review and expert consultation using brainstorming techniques. Subsequently, a risk management team identified 21 key risks and 8 evaluation criteria using focused group discussions. To achieve the research objectives, two questionnaires were developed. The first questionnaire was used to form a pairwise comparison matrix and determine the weights of the criteria using the Fuzzy Buckley method, while the second assessed the importance of the risks. The data were analyzed using Fuzzy SAW and OWA methods. The results indicated that the primary risks were related to the execution phase, highlighting the need for special attention to these risks to improve project outcomes. Unlike many traditional methods, the fuzzy OWA method effectively incorporates the subjective characteristics, risk appetite, and risk aversion of decision-makers, proving to be efficient in risk evaluation.
