Collision  Friendliness
Hull-retaining  design  and  construction  of  the  support  structure.
Construction  Jour  Fixe
Meetings  held  with  the  BSH  on  a  regular  basis  until  the  start  of  the  operating  phase.
Construction  Log
The  construction  log  is  the  daily  documentation  of  the  work  carried  out  and  the  boundary  conditions ­
  during  the  installation  work,  such  as  the  external  conditions  (swell,  wind,  tide,  ice  drift)
and  any  unusual  occurrence.
Converter  Station
The  equipment  of  a  converter  station  is  similar  to  the  equipment  of  an  offshore  substation  but
also  includes  technical  equipment  to  transform  alternating  current  into  direct  current.
The  role  of  the  converter  station  is  to  transport  the  power  produced  by  the  wind  farms  connected ­
  to  it  to  the  coast.  Wind  parks  are  combined  to  “clusters”  and  connected  to  the  converter ­
  station  through  their  respective  offshore  substations.
Cyclic  Loads
Loads  that  result  from  effects  with  a  high  rate  of  regular  or  irregular,  low-frequency  magnitude
changes,  with  or  without  changes  of  direction.
Note:  Often  the  term  cycle  is  used.
Damage-Tolerant  Components
Components  that,  despite  being  damaged,  are  able  to  withstand  the  anticipated  stress  until
the  damage  has  either  been  detected  and  repaired  during  a  scheduled  inspection  or  as  a  result ­
  of  a  non-safety-relevant  functional  failure,  are  called  damage-tolerant  components.
Danger  Zone
Danger  zones  are  areas  in  the  immediate  vicinity  of  which  dangerous  situations  may  arise  that
require  supplementary  protective  measures  to  reduce  hazards  or  limit  damage.  Protective  occupational ­
  safety  and  personal  protection  measures  have  priority.  Furthermore,  the  protection
of  the  environment  and  of  property  must  also  be  observed.  The  typical  danger  zones  of  offshore ­
  structures  are,  for  example,  electrical  switchboards  and  installations,  areas  with  a  higher
fire  load  or  risk  of  fire  (tank  systems,  storage  tanks,  oil  transformers),  explosive  areas,  areas
with  load  handling  (working  with  a  crane)  or  areas  with  an  increased  danger  of  falling.
Decommissioning
Decommissioning  starts  on  the  day  that  regular  operation  and/or  the  operating  release  granted ­
  by  the  BSH  ends.  This  presupposes  that  the  collateral  clauses  of  the  notice  of  approval  as
well  as  the  stipulations  of  the  approval  process  during  the  implementation  and/or  operating
phase  have  been  accordingly  fulfilled.
Decommissioning  Depth
Distance  between  the  top  edge  of  the  decommissioned  foundation  element  and  the  top
ground  surface  (seabed).
Decommissioning  Instruction  Manual
The  decommissioning  instruction  manual  is  a  comprehensible  and  plausible  representation  of
the  scheduled  work  processes,  including  the  technical  boundary  conditions.  It  begins  with  the
preparation  of  the  components  for  decommissioning  and  their  removal  on  transport  vessels  to
the  base  port  (i.e.  first  port  after  decommissioning),  including  the  decommissioning  of  the
