Part  C  -  Time  sequence

The  major  configuration  parameters  as  well  as  the  configuration  standards  and  directives  to  be  applied
shall  be  named  in  the  design  basis.
The  object  of  certification/testing  of  the  design  basis  and  the  basic  design  is  to  ensure  reliable  site  and
configuration  conditions  so  as  to  minimise  potential  errors  in  the  subsequent  detail  design  at  an  early
stage.  In  doing  so,  it  is  necessary  to  ensure  that  the  particular  offshore  wind  turbine  or  offshore  wind
farm  is  considered  as  an  overall  system.  The  certifier/registered  inspector  shall  conduct  an  in-depth
plausibility  check  of  all  site  conditions  and  their  correlations  for  this  purpose,  and  shall  evaluate  all  relevant ­
  configuration  conditions.

3  Design  phase
Detailed  evidence,  design  diagrams  and  specifications  shall  be  prepared  in  the  design  phase.  This  applies ­
  to  support  structures,  the  transformer  substation  with  grid  connection,  measuring  mast  and  any
additional  components  of  the  offshore  wind  farm.  As  a  rule,  the  turbine  has  a  type  certification,  therefore
certification  that  it  is  suitable  for  use  at  the  site  is  sufficient.  The  design  phase  is  accompanied  by  the
site-specific  design  evaluation.
At  least  1  year  before  the  start  of  installation  of  the  systems,  the  certified/reviewed  design  documents
shall  be  presented  to  the  BSH  in  the  form  of  the  design  basis  and  the  basic  design.  Successful  completion ­
  of  evaluating  the  design  documents  shall  be  documented  by  the  certifier/registered  inspector  with  a
certificate  of  conformity  as  well  as  associated  test  reports.
Following  presentation  of  the  certificate  of  conformity  for  the  design  evaluation  and  after  a  concluding
test,  the  BSH  shall  issue  the  approval  for  installation,  if  necessary  with  the  assistance  of  a  recognised
expert  institution,  person  or  group  of  persons.

4  Implementation  phase
Production,  transport,  installation  and  commissioning  shall  be  followed  by  the  certifier/registered  inspector ­
  through  independent  inspections.  Prior  to  the  commencement  of  production,  the  qualification
of  the  production  companies  shall  be  checked,  and  an  inspection  plan  agreed  by  the  project  designer,
manufacturers  and  certifier/registered  inspector.  The  agreed  inspection  plan  shall  be  sent  to  the  BSH
prior  to  the  start  of  production.
The  certifier/registered  inspector  shall  immediately  inform  the  client  and  the  BSH  if  serious  deviations
from  the  requirements  specified  in  the  checked  and  approved  design  documents  become  apparent  during ­
  production,  transport  and  installation.
Completion  of  production,  transport,  installation  and  commissioning  shall  be  documented  with  corresponding ­
  certificates  of  conformity  that  group  together  all  issued  inspection  reports.  Following  presentation ­
  of  the  certificates  of  conformity  for  production,  transport,  installation  and  commissioning  and,  if
necessary,  a  concluding  test,  the  BSH  shall  issue  the  approval  for  operating  the  offshore  wind  farm,  with
the  assistance  of  a  recognised  expert  institution,  person  or  group  of  persons.

5  Operating  phase
Annual  periodical  inspections  shall  be  performed  during  the  operating  phase.  The  certifier/registered
inspector  shall  issue  inspection  reports  on  the  inspected  systems.  The  certificate  of  conformity  for  the
periodical  inspection  shall  be  issued  if  the  inspected  systems  are  operated  in  accordance  with  the  standards ­
  on  which  they  are  based  and  are  maintained  in  accordance  with  the  certified/reviewed  maintenance ­
  plan.  This  groups  together  the  results  of  the  individual  inspection  reports.
