Timetable

Checked:

1.  Origin
•  The  origin  of  the  timetable  must  be  known.

2.  Validity

3.  Quality
•  The  set  parameters  of  the  timetable  must  not  contradict  one  another,  eg  set  speeds  and  given
arrival  times.

4.  Harmonisation
•  Set  parameters  stipulated  in  the  timetable  must  be  observed  under  the  boundary  conditions  expected. ­
  This  comprises  in  particular  the  weather  and  sea  conditions  to  be  expected  as  well  as
the  ship’s  load  state  and  stability  behaviour.

5.  Criticality
•  Since  the  timetable  forms  the  essential  basis  for  voyage  planning,  any  fundamental  change  in  the
timetable  (modified  passage  and  arrival  times,  change  in  the  destination  ports)  will  entail  the  invalidity ­
  of  the  voyage  plan,  which  means  that  in  this  case  re-planning  is  necessary.

6.  Limit  values  and  alarm  facilities
