PIAS module: Hull design and lines plan

What does Fairway do?

  • Fairway is software for design, fairing, manipulation of ship hull forms and conversions of models from other design software.
  • Using Fairway is much like drafting a lines plan on paper, only better.


How does Fairway work?

  • The hull surface is shaped through lines that lie on the surface.
  • 3D surface geometry is automatically created on basis of these lines.
  • User has full control over line geometry, via coordinates of points, defined tangents, line types, etc.
  • Contains versatile fairing options, recreating the use of spline and battens, with user-defined accuracy and stiffness of the spline.
  • Changes in line geometry are automatically included in connected lines.
  • New lines, following the surface, can be added by the push of a button.


Why is Fairway better than NURBS surface modelers?

  • Fairway offers direct control over hull coordinates, as opposed to indirect control via ‘network control points’, ‘vertices’, ‘nodes’, ‘master lines’ and other artificial phenomena associated with NURBS surfaces.
  • Ship hulls generally require an irregular network of lines to describe them: It will take multiple NURBS surfaces to model even the simplest of ships. Thus, the designer is burdened with manipulation, selection and modification of multiple separate surfaces. In Fairway, the network is just a result of the design process, not the governing principle.


What is Fairway used for?

  • Hull form design, starting with a basic shape or a previously defined hull form.
  • Hull design guided by a designed sectional area curve, to meet preset hull parameters.
  • Design modification at any design stage.
  • Hull form transformation and scaling.
  • Completion of partial lines plans.
  • Shell plate expansions of developable and double curved plates including templates.
  • Manipulations on multiple solids for hull, superstructures, bow thrusters, etc.
  • Fairing with user-defined accuracy, up to and beyond production tolerances.
  • Export of hull form data to downstream, engineering software, Finite Element, CFD, DXF, IGES, VRML, tables of offsets, etc.
  • Generation of lines plans and tactile scale models (Rapid Prototyping, 3D printing).
  • Import of DXF and IGES wire frame models, as well as IGES NURBS surface models.


Which tools are available in Fairway?

  • View on frames, waterlines and buttocks at any design stage.
  • Rendered graphics.
  • Generation of frames, buttocks, waterlines and diagonals on user-defined positions.
  • Projection of curved lines onto defined models.
  • A library of simple curve elements.
  • User-defined geometric relations between lines to define bottom rake, fixed shear strake height, etc.
  • Hydrostatic analysis, and a direct link to all PIAS’ modules for further more complex analyses.
  • Automatic modification of the hull to fit developable plates.
  • An expandable library of hull models that may be used as start-off for new projects.
