Climate Risk Assessment in Offshore Wind Assets: Operational Safety and Efficiency

This paper aims to present a comprehensive framework for assessing climate risk in offshore wind assets, considering both physical and transition risks. As climate change increasingly affects design conditions, operational restrictions, and structural integrity, a structured approach is necessary to evaluate exposure, identify hazards, and develop mitigation and adaptation strategies. The study highlights how climate-related risks impact safety, efficiency, and economic viability, providing insights into regulatory and financial implications for offshore wind energy projects. The framework is structured into three key steps: (1) Climate Change Risk Assessment, where geographical coordinates are used to assess exposure to parameters such as wave height, wind gusts, temperature variations, and sea level rise using a CMIP6-based digital tool; (2) Climate Hazard Identification, which evaluates the impacts of these climate conditions on critical equipment, operational safety, and design criteria; and (3) Mitigation, Adaptation, and Resilience Planning, where a structured response plan is developed based on best practices like ISO 14091:2021. This approach enables offshore wind operators to proactively address climate risks and enhance asset resilience. The study demonstrates that conducting a detailed climate risk assessment significantly improves operational safety and decision-making for offshore wind assets. By applying the proposed framework to offshore wind farms, multiple high-impact scenarios were identified, many of which are often overlooked in traditional risk assessments. These include structural vulnerabilities due to increased wave heights, operational disruptions from stronger wind gusts, and long-term challenges posed by rising sea levels. Additionally, the research underscores the regulatory and financial pressures on offshore wind projects, as most large-scale offshore wind developers and financiers are effectively subject to comply with mandatory climate risk disclosures under the Task Force on Climate-Related Financial Disclosures (TCFD) framework. Implementing the proposed methodology enables offshore wind operators to mitigate risks, improve asset longevity, and align with evolving regulatory standards. This paper provides a structured and replicable framework for climate risk assessment tailored to offshore wind assets, integrating climate modeling, risk identification, and mitigation strategies. By bridging gaps in traditional safety and design analyses, this study contributes to the growing need for climate resilience in offshore energy projects. The findings offer valuable technical and theoretical insights to enhance the industry's preparedness for climate-related challenges.
