漂浮式海上风电浮式基础结构安全性评估
Safety assessment of floating foundation structures for floating offshore wind turbines
摘要
Abstract
Focusing on the structural safety of a three-column floating foundation for floating wind turbines,this study systematically assesses its stability,ultimate strength,and fatigue strength.A full-scale finite element model is established using the SESAM software suite.Intact and damaged stability analysis is conducted according to relevant codes.The result indicates that all parameters comply with regulatory requirements and demonstrate excellent anti-overturning capability.In the ultimate strength analysis,based on load conditions considering various wave directions,amplitudes,and periods,it is found that the maximum structural stress concentration occurs at the connections between the buoyancy tanks and columns.Nevertheless,the overall stress levels remain within the design resistance limits.Employing the hotspot stress approach,fatigue strength assessment of critical connection areas shows that the fatigue damage at all checkpoints is less than 1,satisfying the design life requirements.The floating foundation structure meets all applicable code standards for stability,ultimate strength,and fatigue strength.Therefore,the research provides a significant safety basis for the engineering application of floating wind turbines in deep-sea environments.It also offers valuable methodology and guidance for safety assessments of similar projects.关键词
