6.2 Marine st<strong>at</strong>istics<br />

Table 6.2 gives an overview of the most important parameters measured st<strong>at</strong>ing the<br />

mean and maximum values. The WL is referred to the DNN (Danish Normal Zero)<br />

system.<br />

Two examples of time series of wind speeds <strong>at</strong> a height of 15 m, wind directions and<br />

significant wave heights are shown in Figure 6.4 and Figure 6.5. The plots show<br />

rel<strong>at</strong>ively good agreement between wave height and wind speed.<br />
