Managing Uncertainties in Offshore Wind Foundation Concept Design: A Comprehensive Approach

This paper addresses the complexities and challenges faced in the early stages of offshore wind turbine foundation design. The focus is on understanding and managing the uncertainties inherent in Wind Turbine Generator (WTG) parameters, MetOcean data, geotechnical and geophysical characteristics, and clustering strategies. It explores the critical role of WTG parameters, including loading effects and natural frequencies, and their impact on foundation design. The paper also delves into the significance of accurate MetOcean data in determining environmental loads and examines the stages of geotechnical and geophysical assessments that provide valuable insights for concept design. A key aspect of the study is the clustering strategy, which optimizes the design process by minimizing the number of distinct foundation designs required, especially in large wind farms with diverse environmental conditions. This comprehensive approach addresses the varying levels of uncertainty in data and design parameters, offering solutions to balance accuracy with available information. The paper aims to guide practitioners in navigating the complexities of offshore wind foundation design, promoting efficient, cost-effective, and reliable solutions.
