Objective:
The objective of WP2 is to obtain further insight into the physics relevant for the extreme loads on the wind turbine structures. This is achieved through physical model tests and numerical modelling. Mathematical uncertainty quantification is exploited within the wave models to enhance their applicability in stochastic design.
Activities and results
• Experiments with steep and breaking wave impacts on sloping bed with/without a current.
• Derivation of a slope reduction factor for extreme loads.
• Quantification of current effect on loads.
• Kinematics and corresponding forces for 2D and 3D waves.
• Mathematical uncertainty quantification for wave kinematics and loads.
• Numerical reproduction and extension of derived 3D and slope load effects.
• Numerical study of 3D wave formation and effects on crest height distribution and load distribution.
