Part  C:  Time  sequence

1  General
The  time  sequence  of  a  project  generally  extends  through  the  following  sections  (see  Table  2):
•  Development  phase
•  Design  phase
•  Implementation  phase  (production,  transport,  installation,  commissioning)
•  Operating  phase
•  Decommissioning  phase
The  required  documents  shall  be  presented  to  the  approval  authority  for  inspection  and  approval  in  good
time  during  the  individual  project  phases  (see  Table  2).  Furthermore,  the  body  responsible  for  the  project
shall  ensure  that  the  approval  authority  is  continuously  included  in  the  project  phases.
Prior  to  the  issue  of  an  approval,  it  is  necessary  to  conduct  a  preliminary  survey  of  the  site  in  order  to
record  all  site  conditions  relevant  for  the  design,  this  forming  the  starting  point  for  a  design  basis  and  a
preliminary  study.  The  purpose  is  to  establish  whether  the  site  meets  the  technical  criteria  for  installation
and  operation  of  an  offshore  wind  park.
The  design  basis  that  also  has  to  be  prepared  and  presented  at  regular  intervals  in  the  approval  process
during  the  development  phase  generally  contains  the  initial  technical  requirements.  This  contains  all
data  and  figures  required  for  the  particular  element  of  the  offshore  wind  park  at  its  relevant  site  as  well  as
certification  methods  that  are  required  for  drafting  a  stable  and  serviceable  construction  in  accordance
with  the  generally  recognised  state  of  the  art  or,  failing  that,  the  state  of  current  scientific  progress.  It  is
based  on  qualified  investigations  and  expert  reports.  The  design  basis  as  well  as  the  preliminary  draft
prepared  from  it  form  part  of  the  application  documents  that  are  used  as  the  basis  for  assessing  the
approval  preconditions  within  the  scope  of  the  decision  on  whether  the  project  may  be  approved.
A  certifier/registered  inspector  performs  a  plausibility  check  of  the  design  basis  and  a  preliminary  draft
based  on  it.  This  involves  the  certifier/registered  inspector  testing  both  the  plausibility  of  the  site  conditions ­
  and  their  data  sources  as  well  as  the  plausibility  of  the  preliminary  draft  and  the  methodology  used.
The  test  report  shall  be  presented  to  the  approval  authority.

2  Development  phase
The  site  data  shall  be  assembled  based  on  qualified  reports  in  order  to  ascertain  the  design  basis  and
the  basic  design,  this  site  data  including  for  example:
•  Meteorological  and  oceanographical  reports  (wind,  waves,  currents,  bathymetry,  etc.)
•  Geotechnical  report
•  Other  reports,  e.g.  on  icing,  scouring,  etc.
The  correlation  between  individual  site  conditions  shall  be  presented,  in  particular  the  correlation  of  wind
and  waves.  The  survey  concept  for  preparing  the  geotechnical  report  shall  be  agreed  with  the  certifier/
registered  inspector  and  the  approval  authority  on  the  basis  of  the  „Standard  Baugrunderkundung“  JdJ  of
the  BSH  in  its  current  version  before  the  start  of  the  survey.  Deviations  from  the  „Standard  Baugrunderkundung“ ­
  JTj  shall  be  applied  for  to  the  BSH,  presenting  their  equivalence,  and  justified.
The  „collision  friendliness“  (see  Appendix  T)  shall  be  documented  in  a  report  for  the  draft  of  the  support
structure  prepared  on  the  basis  of  the  site  conditions,  and  included  in  the  design  basis  and  the  preliminary ­
  draft.
