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  design ­
  storm  is  currently  considered  as  being  sufficient  for  the  design.  Accordingly,  no  further
storm  events  need  to  be  included  with  respect  to  verifying  sustainability.
