    control centres with the same guidance modules
    and vessel data as the crew.

Module interrelationships
  • SHIP DESCRIPTION
  • Data needed for indentation analysis and hull
    girder section modulus and shear capacity
    assessment.
  • For the bottom damage simulation key data
  • Thickness of plating in outer and inner bottom
  • Stiffener dimensions and spacing
  • Longitudinal and transverse girders spacing
    and dimensions
  • Transverse and longitudinal bulkheads position
  • Longitudinal strength assessment
  • Plate thickness of decks and bulkheads
  • Longitudinal stiffeners dimension
  • Dimensions of any longitudinal stringers and
    girders

ENVIRONMENT Data related to environmental
conditions, i.e. tidal variations, wave height,
wind force and current direction. Updated
according to weather forecasts, for example
predicted evolution over say 3 days.
BOTTOM TOPOLOGY Data describing the geometry of
the sea floor. z z(x,y). The coordinate is
related to e.g. mean water level.

Module interrelationships
HULL GIRDER LOAD VS CAPACITY The ultimate
resistance of the hull girder in bending or shear
is visualised including the degradation in
capacity due to damaged bottom panels. The still
water loads and added wave loads are plotted.
The predicted increase of wave loads due to
forecasted aggravating weather and any
degradation of the capacity due to progressive
development of damage should be indicated. The
still water load may also change due to change in
contact force, flooding or outflow from tanks
etc...
VERES Calculates the wave induced bending moment
and shear force on the hull girder. Input to this
calculation is hull form, deadweight distribution
( from SHIPSHAPE), wave height and periods tide
from ENVIRONMENT.

  • Used to test the concept of DSS-DC on the ship
    crew and managers
  • Specification of how emergencies are handled and
    actors cooperate
  • A3 and A4 define other settings and incidents
  • Must be used in conjunction with A1 and A2

  • The vision of FLAGSHIP is to create the mechanism
    by which the expertise of all the required actors
    can be brought together in real time,
    independently of their location, and given the
    required information (in the right format, at the
    right time and incorporating the highest level of
    knowledge) to solve all the problems which
    confront a ship operator that includes problems
    relating to the ship itself and its equipment
    (e.g. hull monitoring, equipment diagnostics,
    maintenance planning), its day-to-day operation
    (e.g. navigation, cargo, rule compliance) as well
    as emergencies (collision, fire, etc.).
