The standardised curves of wind speed and significant wave height are shown as dashed 
lines in Figure 3-1.1. They are defined as follows: 
• Wave height: max. H s over a period of three hours, linear decrease to 0.5 H s after 
±17.5 hours. 
• Wind speed (recommendation according to EU project RECOFF) 
v(t) = 1 - 0,09 (t/10) 0 ' 45 with t = Zeit in [min] {-1.050 min < t < +1.050 min}

Figure 3-1.1 Development of wind speed and the significant wave height during the design 
event. 
In order to verify sustainability, all potential reductions of sustainability due to the design event 
shall be taken into account. As all design loads are taken into consideration, the unique de 
sign storm is currently considered as being sufficient for the design. Accordingly, no further 
storm events need to be included with respect to verifying sustainability.
