Structural Detailing of Ships
More and more companies are automating their activities. CAD systems are enjoying increased popularity with designers in particular. Their use makes drawing and calculation tasks less labor-intensive, certainly when alterations to the design need to be made. The link to actual productions is, however, often a bottleneck. Working methods to produce made-to-measure frames, floors, shell plates and superstructure parts still require a lot of time and skill. CAM systems are the solution.

Autobuild Autobuild is an integrated 3D modeling program used to define the entire internal structure for construction and production purposes. Designers find Autobuild useful in the preliminary design stage for its weight and center calculations and to assess the viability of a project. Autobuild is used to layout and design interior structures such as bulkheads, floors, frames, flats, and fit them to the hull envelope. The original hull shape comes from the Autoship program.

Autoplate Autoplate performs plate expansion calculations for both developable and non - developable hulls. Autoplate helps in the layout and forming of the shell plating. Autoplate works directly on hull designs created in Autoship. Plates are created by defining boundaries, which are simply a combination of curves and surface/polyobject edges. Several plate expansion/forming methods Isotropic or unidirectional expansion, shrink only, stretch only, or mixed expansion are possible.

AutoStructure Autostructure is used to create a 3D model of a vessel structure and to output the parts of that model in CAD format. The CAD representation can be used to either prepare construction drawings or for input to NC cutting processors. Autostructure utilizes an Autoship-generated hull and/or superstructure and can also include the shell plate information created in Autoplate.

Dfstruc Dfstruc generates the pieces with regard to the previous definition done in Dfshell and allows all the details that it needs for its total definition to be inserted. The user can look up the database of pieces making use of selection filters like: block, thickness, kind of piece, etc. DFstruc automatically obtains the intersection between pieces, inserts slots produced by solder seams and the longitudinal and transversal slots asociated to the girders of shell and bulkheads, marks, etc.

Dfshell Main characteristics of Dfshell are Shell and deck plates expansion, expansion of any type of plate without any limitation as for its shape or numer of sides, finite element expansion method, geometrical and interactive definition of seams and butts., structural elements positioning and three-dimensional structure management. Once the plates have been expanded you can obtain offset tables for the preparation of templates for shell plates forming.

MasterShip Mastership operates in combination with Autocad. The Mastership CAD/CAM software package has been specifically developed to address the automation between CAD and CAM. Working methods to produce made-to-measure frames, floors, shell plates and superstructure parts still require a lot of time and skill.

Msdev Msdev is a MultiSurf utility that reads in panel ruling files created in MultiSurf and outputs DXF, 2D, and/or text files of the developed shapes of the panels, plus a "weights" file. The output text file contains the 2D coordinates of either the ruling lines or equal bend lines of the developed panels, plus the coordinates for any contours, snakes, magnets, and rings included in the ruling file.

Msplex Msplex is a compound-curved plate expansion utility. Plate expansion is the process of designing a flat blank to be cut from stock and subjected to a compounding process in order to form a curved plate. The primary product of plate expansion is an expanded outline for each individual plate. This solution enables accurate lofting and NC cutting of blanks which, through application of a suitable compounding process (e.g. die pressing, roller planishing, peening, line heating, etc.), evolve into curved plates precisely fitting their prescribed positions on the hull.

ShipConstructor The ShipConstructor software suite is a powerful, easy-to-use, AutoCAD based product modeling tool for ships and offshore structures. Fair, loft, model 3D structure, route pipe, outfit, nest parts, and produce NC-code all within an easy-to-use, familiar interface.

SeaSolution The SeaSolution is is comfortable tool for geometric design especially for fairing lines and shell plates development. There are two modules; surface and shell. The module is able to define hull surfaces for any type of ships, surfaces of superstructures, decks, platforms and bulkheads. The shell uses the surface module results and able to create mathematical model of hull structure. Using the module you can define decks, longitudinal and transversal bulkheads, trusters, anchor pockets, platforms. Then you can create and develop shell plates.

Workshop Workshop construction module is used to define the location of parts on the vessel, generate part geometry and build a database of parts which can be passed to other CAD systems for further detailing or sent directly to NC cutting systems. An integrated database within Workshop progressively contains all of the parts you define and calculate. Quantities, areas, weights, centres of gravity and cutting lengths are calculated and tabulated.
