Viking
Systems has implemented its extensive knowledge of structural design of
ships and floating structures into its computer program SAGA for Ships for
analysis and classification verification solutions for ships and floating
marine structures |

SAGA
Structural Modeling |
|
|
Viking Systems has developed a computer program SAGA to
rapidly create structural finite element models based on hull offsets,
structural drawings or general arrangement drawings.
The methods works in 3D and 2D in combination with a ship
coordinate system for assembly into a 3D structural finite element model.
The program can also create a model without CAD drawings, by using
a ship nodal description to create the majority of the regular ship
structure. The modeling includes all structure, i.e. plates,
beams, and stiffeners. |
|
 |
This
modeling part of the program is typically used in combination with a
Nastran capable finite element modeling system for creation of the
additional detailed structure. SAGA
maintains the plate stiffening system in terms of orientation, spacing and
scantlings. The Nastran
export feature determines the properties of beams using hybrid beam theory
to represent the beam/plate interaction.
SAGA performs loading of structural finite element models with hydrostatic
and hydrodynamic loads |

SAGA
Structural Database and Graphics Systems |
|
|
 |
 |
Viking
Systems has developed a feature in its SAGA computer program for
evaluation of ship structures. This
feature allows the model to be evaluated against a set of structural
rules, such as those required by classification societies.
This feature provides the designer an extremely reliable, rapid,
and complete evaluation of a finite element model. |

SAGA
Structural Database and Graphics Systems |
|
SAGA
allows for assessment and graphical verification of any data present in
the 3D ship model, and allows in addition user-defined database items.
This feature assists in determining weight and areas by region. SAGA creates, loads, and evaluates the results of a finite
element model.
