Part  B  -  Verifications  and  approval  requirements

77

Danger  zones  outside  the  offshore  station  shall  be  taken  into  account  and  specified  to  the  extent ­
  that  hazards  caused  by  falling  parts  or  suchlike,  by  collisions,  or  by  smoke  and  fire  drifting
to  structural  works  in  the  vicinity  or  to  watercraft,  for  example,  are  kept  as  low  as  possible.
Danger  zones  shall  furthermore  be  separated  from  safety  zones  whose  function  and  equipment ­
  are  indispensable  for  the  safe  operation  of  the  offshore  station.
Danger,  protection  and  safety  zones  shall  already  be  shown  in  a  layout  plan  in  the  development ­
  phase  of  the  offshore  station  and  shall  be  updated  with  more  detail  in  the  subsequent
design  phase.

5.2  Development  phase
5.2.1  Preliminary  remarks
The  starting  point  is  a  functional  description  of  the  offshore  station  whose  purpose  is  to
present  the  safety  of  all  persons  and  the  environment  in  a  way  that  can  be  substantiated  and
verified.  This  covers  all  operating  phases  and  states  as  well  as  emergency  situations.  The
functional  description  is  the  fundamental  requirement  for  the  design  of  the  offshore  structure,
where  requirements  from  occupational  health  and  safety  shall  be  iteratively  taken  into  account
in  the  design  as  the  planning  progresses,  and  expressed  in  more  concrete  terms  by  means  of
detailed  concepts  which  shall  submitted  to  the  appointed  inspector  for  inspection.
As  early  as  the  development  phase,  the  design  should  be  based  on  a  full  safety  assessment  tailored ­
  to  the  whole  structure  in  accordance  with  the  requirements  of  occupational  health  and  safety.
It  is  a  good  idea  to  give  consideration  to  these  functional  and  technical  requirements  at  an  early
stage  of  the  development  process,  since  their  final  design  has  to  be  included  during  the  design
phase  of  the  topside  at  the  latest.  According  to  chapter  5.2.4,  only  the  verification  report  of  the  appointed ­
  inspector  for  this  study  has  to  be  submitted  to  BSH  at  the  time  of  the  development  phase.
The  following  aspects  concerning  the  implementation  of  their  design  in  the  functional  description
and  individual  concepts,  if  applicable,  serve  here  as  topical  proposals  intended  to  describe  the
planned  modes  of  operation  of  the  operational  structure  (topside)  in  a  comprehensible  way:
•  Operational  concept  (incl.  transport,  installation,  commissioning,  maintenance,  shut-down
and  decommissioning):
-  Operating  situations,  such  as  normal  operation  including  winter  operation,  operation
when  malfunctions  occur,  or  emergency  operation
-  Transport  and  installation  states
-  Operating  modes,  such  as  manning,  mother-daughter  concept
-  Interior  spaces  (e.g.  technical  services  zones,  sleeping  accommodation,  offices,  communal ­
  spaces,  first  aid  room,  workshops,  stores,  control  and  communication  rooms)
-  Operational  or  weather-related  limitations,  such  as  safe  accessibility  of  parts  of  the  installation, ­
  for  example
•  Behaviour  of  the  structure  should  a  ship  collide  with  it
•  Subdivision  into  protection  and  danger  zones  (explosion  zones,  high-voltage  areas  and
others)  in  accordance  with  the  occupational  health  and  safety  requirements  and  the  design
requirements  resulting  therefrom
•  Design  concepts  for  the  different  fire  scenarios  from  the  aspect  of  fire  and  explosion  protection ­
  (transformer,  living  accommodation,  workshops,  store,  tanks  etc.):
-  Illustration  of  fire  compartments
-  Fire  detection  system  (fire  detection  on  decks  and  in  rooms,  for  example)
-  Fire  protection  (passive  (e.g.  thicker  walls)  and  active  (stationary  and  mobile  fire-fighting
systems))
