In AVEVA Hull Detailed Design the basic modelling unit is a 'panel' - a functional structure ranging in size from a small bracket to the level of decks and bulkheads. This object-oriented design enables all associated piece parts to be generated automatically from the panels.
A ship design can be developed quickly, because the software automatically carries out the lofting work and derives the exact shape of each part.
An extensive range of 'intelligent' shipbuilding standards for brackets, stiffeners, notches, cut-outs and holes enables efficient hull design using parts that automatically adapt to their surroundings. For example, plate edge geometry is automatically calculated according to steel thickness, the joint angle and the required weld prep.
Design intent makes the hull model independent of fixed 'numeric' geometry. Hull Detailed Design automatically uses design intent information for lofting work and to define the exact shape and characteristics of each part. Design changes are automatically reflected in changes to connected parts.
Planar Hull Modelling
Inner hull structure is modelled as plane panels, creating a detailed model from which part manufacturing and hull assembly information is derived. Knuckled and swaged panels can also be defined.
As panels are moved or duplicated, their shapes automatically adapt to their surroundings. New parts are automatically numbered using customised rules.
Associativity, defined during modelling, enables the entire model to automatically adapt to a change of hull form or the position of a deck.
Curved Hull Modelling
A curved panel generation facility is used to build complete shell panels, including the curved plates, longitudinals and transversals.
Curved plates are automatically developed to suit the shipyard’s production methods. Holes can be defined, developed and used for marking or cutting. Early material estimates for shell profiles can be readily obtained.
Shell Expansion and Body Plan views can be generated automatically and used for modelling and queries.
All panel drawings are linked to panels in the model, ensuring consistency between model and drawings, and efficient design documentation.
Drawings may be either symbolic or full 3D representations. Symbolic-style drawings are used for classification and working drawings, while 3D representations serve the various hull assembly drawings. A full set of standard 2D drafting functions is provided.
AVEVA Hull Detailed Design can automatically create all the necessary manufacturing and assembly documents. It features:
- Automatic parts generation from the hull panel models, with weld shrinkage allowances, alignment markings and part markings.
- A Part Checking function, which displays the automatically created part with all labels, marking, excess material and bevel information.
- Plate and profile nesting functions, to nest parts on raw plates and profiles, and produce CNC data for cutting and marking. Any steel substitution rules are considered and scrap minimised.
