General
Implementation  plan
This  contains  the  planning  documents  that  are  ready  for  implementation  on  the  basis  of  the  basic
design  approved  by  the  BSH  for  realising  an  offshore  wind  farm.  The  main  emphasis  of  implementation ­
  planning  lies  in  preparing  works  plans,  usually  on  a  relatively  large  scale.  The  objective  of  implementation ­
  planning  is  to  achieve  a  set  of  plans  that  can  be  released  for  construction.  The  tested
implementation  plan  approved  by  the  BSH  concludes  the  design  phase.
Basic  design
This  contains  the  definitive  basis  for  taking  planning  decisions  when  realising  an  offshore  wind  farm.
The  objective  is  to  achieve  a  coherent  and  achievable  planning  concept  that  takes  account  of  all
project-specific  issues.  The  checked  basis  design  approved  by  the  BSH  concludes  the  first  subsection ­
  of  the  design  phase.
Design  basis
This  contains  all  data  and  figures  required  for  the  particular  element  of  the  offshore  wind  farm  at  its
particular  location  that  are  necessary  for  designing  a  structurally  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.
Conformity
This  refers  to  a  match  with  defined  requirements.
Preliminary  draft
This  contains  several  planning  variants  which  are  already  significant  parts  of  the  realisation  of  an
offshore  wind  park.  The  checked  preliminary  draft  approved  by  the  BSH  forms  the  conclusion  of  the
development  phase.

Foundation  elements
Ground
This  is  the  system  consisting  of  one  or  more  layers  of  soil.
Soil  (loose  rock)
This  is  the  general  material  designation  for  the  various  layers  of  the  ground.
Characteristic  values  of  the  soil  parameters
These  are  carefully  selected  mean  values  of  a  typical  bandwidth  of  these  values  for  the  particular
soil  type  under  the  circumstances  to  be  considered,  the  magnitude  of  which  is  to  be  viewed  as  assured ­
  for  the  service  life  of  the  foundation.  The  geotechnical  engineering  model  in  which  they  are  to
be  used  shall  also  be  taken  into  account  when  defining  them.
Design  values  of  the  soil  parameters
These  are  values  derived  from  the  characteristic  values  of  the  soil  parameters  by  reduction  (if  necessary ­
  by  augmentation)  with  safety  factors.  It  is  necessary  to  use  them  in  calculations  in  which
the  safety  factors  cannot  be  used  or  cannot  be  exclusively  used  on  the  loading  values  (calculated
with  characteristic  values  of  the  soil  parameters).  In  each  case,  they  shall  be  defined  with  reference
to  the  geotechnical  engineering  model  in  which  they  are  to  be  used.
