� 3D, 3-component Kaimal turbulent wind field (10 minutes sample)<br />
� 6 bin-combinations for each wind speed bin<br />
� log. vertical shear with ground roughness length of 0.002m<br />
� ETM is site specific<br />
� NSS with irregular waves defined using Jonswap spectrum (peakness = 3.3)<br />
� NCM using near-surface current, decreasing linearly to the sea bed<br />
� extreme loads for each load case group (e.g. 1.3aa) are calculated as the mean of the maxima from<br />
each of the six seeds<br />
