'Intelligent' Design

AVEVA Hull Detailed Design comes with an extensive range of 'intelligent' shipbuilding standards for brackets, stiffeners, notches, cutouts and holes. 'Intelligent' means that these parts automatically adapt their shapes to the context in which they are used. For instance, plate edge geometry will be automatically calculated according to the required weld preparation type, the thickness of plating and the angle between the joined parts. Standards can be customised and new ones added.

• Extensive interactive facilities enable the user to define any curved member with respect to basic geometry locations or to existing curves. Curved plates are automatically developed according to the methods used at the shipyard. Holes in curved plates can be defined, developed and used for marking or cutting.
• Early material estimates for shell profiles can be obtained using the longitudinal tracing facility and the shell plate development functions.
• A curved panel generation facility is used to build complete shell panels, including the shell plates and the detailed descriptions of longitudinals and or transversals, for production purposes.
• A shell expansion view can be generated automatically and may be used for modelling and queries. These views normally show either the port or starboard half the ship. However, they may also be developed across the centre line, be restricted to certain parts of the shell, or be developed from arbitrary curves or planes. Holes in the shell profiles and in the internal structure against the shell can be shown symbolically in a shell expansion view.
• Similarly, Body Plan views can also be created automatically and be used for modelling and queries.

A body plan view

• All kinds of panel drawings maintain a link to the panels in the model. Changes in panels can therefore be carried out via their drawings, offering the powerful facility to 'model in a drawing'. This ensures consistency between the model and its related drawings, and reduces the time for documenting the design.
• Drawings can be made either with a symbolic representation of stiffeners, seams, notches and drain holes, or with full three-dimensional representation. The symbolic-style drawings are traditional for classification and working drawings, whereas the full representation can be used for the various assembly and erection drawings. The drawing functions provide the following features:
  • General 2D drafting.
  • Model picture generation.
  • Automatic generation of a shell expansion and body plan views.
  • Access to, and viewing of, outfitting objects such as equipment, pipes and cables.
  • Associative labels and dimensions.
  • Hidden line removal.
  • Section details.

Design Intent

Design intent, defined during modelling, is used to make the hull model as independent of fixed geometry as possible. The design intent for each object is stored, rather than simple 'numeric' geometry. Hull Detailed Design automatically uses this design intent information to carry out the lofting work and determine the exact coordinate information that defines the shapes and characteristics of the parts. Changes in one part will automatically be reflected in changes to connected parts.

• The intelligent shipbuilding standards in Hull Detailed Design make this model work highly efficient.
• The complete inner structure of a vessel is modelled as plane panels, including plates, stiffeners, brackets and flanges, creating a complete and detailed model to be used for the retrieval of manufacturing and assembly information.
• Knuckled and swaged panels can also be defined.
• To speed up the design process, panels can be moved and duplicated, automatically adapting their shapes to their new surroundings. The new parts can be automatically numbered using customised rules.
• The associativity of the model defined during modelling means that the entire model can automatically adapt to a change of the hull form or the position of a deck. A design can be developed quickly, because the application automatically carries out the lofting work and determines the exact shapes of the parts.

Production Information

• Automatic Parts Generation. The plates and profiles to be manufactured (including all small parts like clips and collars) are created entirely automatically from the hull panels, incorporating all necessary weld shrinkage allowance and edge preparation. Part alignment marking is available and can be customised to yard practice. Each piece part is marked with all the necessary information for a simplified assembly process.
• Shrinkage Facility. This facility compensates for the shrinkage caused by welding in the assembly process, using calculations based on shrinkage actually measured in the workshops. The correct amount and direction of shrinkage allowance is automatically applied both to plates and profiles.
• Part checking function. This displays the automatically created part with all labels, marking, excess material and bevel information.
• Production information can be automatically or semi-automatically extracted from the Hull model:
  • 2- or 3-axis plate cutting
  • Templates for the rolling and bending of the shell plates
  • Plate jigs and pin jigs for curved assemblies (there is an additional feature for interactively changing the automatically created jig planes)
  • Manufacturing lists, sketches and robot information for longitudinal and transverse frames and webs, including information for inverse line bending
  • Lists of weights and centres of gravity
  • Manufacturing lists and sketches for stiffeners
  • Material lists
  • Part lists
  • Early estimates for material and welds
• The plate nesting function is used to nest parts on raw plates and produce NC/CNC data for cutting and marking, together with a workshop sketch. Quick nesting of plates using automatic parts selection is available, and there are facilities for the handling of surplus plate material. Parts can be clustered and smaller parts nested in openings.
• Profile nesting. Profiles generated as planar stiffeners, flanges or pillars, or as curved longitudinals and transversals, can be automatically nested on a set of raw profiles defined by the shipyard. Any steel substitution rules set up by the shipyard are considered during the selection of raw material. The nesting algorithm will minimise scrap, taking into consideration the geometry of the end cuts, any defined bevel and different orientations of symmetrical profiles.
