PO104: Assessment of Spatial Agreement Between Typhoon-Related Risk Index and Buoy-Recorded Extreme Winds for Offshore Wind Farm Site Selection in Korea

Abstract
This study quantitatively evaluates typhoon-related risks for offshore wind farm sites in Korea by developing a grid-based Typhoon Risk Score (TRS) derived from 61 historical typhoon events (1978–2024), including track, radius, and central pressure data. Using spatial GIS analysis, TRS was calculated for Korea’s Exclusive Economic Zone and applied to 99 currently permitted offshore wind project locations, identifying 14 as high-risk sites (TRS > 0.7). Validation was performed by comparing TRS results with extreme wind speeds measured across nine long-term offshore buoys and further adjusted via ERA5 reanalysis data using the Measure-Correlate-Predict (MCP) method. Findings reveal a strong correlation (r > 0.7) between the MCP-adjusted extreme wind speeds and TRS, indicating that TRS robustly captures climate-driven spatial risk patterns relevant to both typhoon frequency and intensity. The study also notes site-specific variations: high TRS does not always correspond to observed wind extremes due to local meteorological and geographic effects. Overall, the TRS offers a practical tool for siting and designing offshore wind farms with improved consideration of typhoon hazard. The methodology underscores the importance of integrating observed measurements, reanalysis adjustments, and multivariable correlation to enhance risk assessment reliability. These insights can help policymakers and developers optimize site selection and structural standards for Korea’s rapidly growing offshore wind sector, facilitating safer and more resilient renewable energy expansion.
