Abstract
Offshore projects are vital to the construction sector as they drive innovation, expand opportunities for large-scale infrastructure development, and support the growth of renewable energy, enhancing global energy security and economic strength. Offshore platforms present a wide and complex subject to analyze. Risk management in offshore projects is essential for ensuring the safety, sustainability, and financial capability of operations, as it helps identify, assess, and mitigate potential hazards.In the construction industry, a variety of project delivery methods (PDMs) are employed to establish the contractual requirements and relationships between the owner, designer, and contractor.Choosing the appropriate project delivery method is critical for effective risk management as it helps to allocate and mitigate risks more efficiently throughout the construction process. The objective of this study is to study the impact of PDM on risk assessment of offshore platform project’s lifecycle and to assess and recognize the risks related to offshore projects to improve understanding and optimize performance outcomes. Risk identification was carried out through extensive literature review followed by a risk assessment involving the Delphi Technique to evaluate the probability and impact of each risk. It was found that management risks account for an average of 52% of all identified risks. Technical risks account for an average of 24% of the identified risks. Historical data on real-world projects delivered using EPC were utilized to validate these risks’ impact on risk management process. It is noted that the implementation of a risk response strategy led to a 27% reduction in the estimated budget and a 14% decrease in the estimated duration. Additionally, this study employs the Best Worst Method (BWM) and the Technique for order Preference by Similarity to Ideal Solution (TOPSIS) to identify the optimal project delivery method for offshore projects through a lifecycle-focused risk assessment. To this purpose a BWM-TOPSIS system was developed in the context of the offshore projects. The results showed that Integrated Project Delivery (IPD) and Construction Manager at Risk (CMAR) are the most effective methods due to their higher integration level, collaboration, and preventive risk management .The proposed hybrid BWM-TOPSIS model was validated by its implementation on two real world data projects .Based on analysis , it was found that the Integrated Project Delivery (IPD) method is the best alternative for both projects.The study emphasized the significance of proactive risk identification and mitigation and the significance of implementing a systematic methodology for decision-making while dealing with the complexities of offshore projects.
