Part  B  -  Verifications  and  approval  requirements

•  Description  and  illustration  of  lightning  and  overvoltage  protection  installations  and  the  design ­
  standard  according  to  which  the  system  shall  be  planned  and  installed
•  Description  and  illustration  of  special  protection  installations,  such  as  those  for  hazardous
materials
•  Information  and  illustration  of  pressure  generation  systems  (overpressure  as  well  as  negative ­
  pressure)
•  Information  on  the  requirements  from  the  evacuation  plan  and  the  escape  route  plans  and
the  design  requirements  resulting  from  this.

5.3.1.3  Access  concept
The  offshore  station  shall  have  means  of  access  for  staff  and  material.  The  construction
measures  resulting  from  the  access  concept  shall  be  shown  in  detail;  they  shall  contain  the
information  below.
The  concept  shall  consider  the  normal  operation  of  the  offshore  station.
The  following  aspects  at  least  shall  be  taken  into  account  in  sufficient  detail:
•  Definition  of  the  field  of  application
-  Normal  operation  after  erection,  incl.  maintenance,  repair,  standstill
•  Description  of  the  operational  structure  and  the  support  structure  of  the  offshore  station  in
relation  to  its  utilisation  (offshore  converter  station,  substations,  accommodation  etc.)  and
configuration  (i.e.  offshore  station  complex  or  individual  structure)
•  Site  description,  incl.
-  Environmental  conditions  to  be  expected  (statistical  annual  view)  and  alignment  with
operational  requirements  or  plans  concerning  frequency  of  use
•  Planned  number  of  persons  or  utilisation  of  the  access  systems  (transport  of  persons,
transport  within  the  wind  farm,  normal  operation  or  emergency)
•  Planned  means  of  access  (helicopter  landing  pad,  area  with  winch  operation,  static  or  active ­
  boat  landing  systems,  crane  systems).  At  least  two  independent  means  of  access  to
the  offshore  station  shall  be  provided.
•  Restrictions  on  access:
-  Structural  restrictions  (e.  g.  loads,  dimensions)
-  Weather  conditions
-  Amount  of  swell
-  Tidal  water  levels
-  Wind  speeds
-  Visibility  conditions,  incl.  times  of  day
•  Construction  or  structural  requirements  placed  on  access  systems
•  Requirements  placed  on  means  of  transport  (ship,  helicopter,  crane)
•  Interfaces  to  other  concepts  (e.  g.  evacuation,  operation).

5.3.1.4  Space  utilisation  plan
A  plan  for  the  utilisation  of  the  spaces  on  the  different  decks  shall  be  drawn  up  and  shall  state
the  distributed  loads  (e.g.  position,  dimensions  and  weight  of  the  loads).
