Revolutionizing Offshore Project Delivery: How Hybrid BWM–TOPSIS Transforms Risk Assessment and Decision-Making

Utilizing a hybrid decision-making framework that combines the Best Worst Method and TOPSIS to systematically quantify lifecycle risks and incorporate collaborative stakeholder input, thereby revolutionizing project delivery method selection and optimizing resource allocation in complex projects.


The world of offshore construction is fraught with complexity, high stakes, and an array of unpredictable risks that threaten budgets, schedules, and operational safety. Traditionally, selecting the optimal project delivery method (PDM) has been a challenge—requiring a delicate balance of risk analysis, cost control, stakeholder interests, and long-term project viability. Enter a new era of decision-making: a hybrid Best Worst Method (BWM)–TOPSIS framework that systematically elevates how these projects are planned and managed.

**Hybrid Intelligence in Risk Quantification**

At its core, the BWM–TOPSIS approach innovatively intertwines two leading Multi-Criteria Decision Making (MCDM) techniques. BWM excels by extracting consistent and objective weights for project risks by comparing the most critical (best) and least critical (worst) factors, reducing common human inconsistencies and biases in traditional weighing methods. By coupling this with the systematic ranking precision of TOPSIS—which identifies solutions closest to the “ideal” across all weighted risk factors—offshore project managers now have a methodology that is both rigorous and tailored for real-world complexities.

**Collaborative Decision-Making as a New Standard**

One of the standout innovations of this framework is its embedded emphasis on stakeholder collaboration. By capturing collective input from experts spanning management, technical, financial, and external domains, the approach sidesteps narrow perspectives and taps into broad-scope expertise. This participatory structure ensures risk priorities are seen from all strategic angles, bolstering not only the robustness of analysis but also stakeholder buy-in throughout the project lifecycle.

**Lifecycle Risk Integration for Accurate PDM Selection**

Where previous models often focused on isolated phases or risks, the hybrid BWM–TOPSIS model enables a comprehensive lifecycle view. Risks—from financial uncertainties in early development, technical glitches during construction, to environmental impacts in operations—are identified, weighted, and rolled into the final decision. All recognized risks, regardless of their nature or timing, directly influence the selection and prioritization of project delivery methods, ensuring the chosen path is resilient from inception to completion.

**Actionable Insights: IPD and CMAR Lead the Way**

Applied to real-world offshore projects, the process yielded clear results: Integrated Project Delivery (IPD) emerged as the most effective method, championed by its unified approach, early stakeholder engagement, and shared risk model. Construction Manager at Risk (CMAR) also ranked highly, highlighted for its proactive risk oversight and collaborative planning. Such evidence-based prioritization is a leap forward—removing guesswork and grounding decisions in quantified, stakeholder-endorsed data.

**Closing the Gap Between Theory and Practice**

Validation through industry case studies demonstrated a strong correlation between the model’s recommendations and actual project outcomes, confirming its value as a reliable guide for both current and future offshore ventures. In an industry where each project faces unique risk environments, the adaptability and precision of the hybrid BWM–TOPSIS methodology set a new benchmark for smart, agile project delivery.

**In summary, this hybrid framework represents a significant leap in offshore construction management—enabling data-driven, collaborative, and lifecycle-focused decision-making that optimizes risk mitigation and resource allocation for complex projects.**
