CAD/CAM

Autoship Systems Corp. recently adopted a "total system" approach, which is embodied in all of its products. Autostructure (pictured) performs internal structural modeling tasks.

Designed to support many networked engi- neers working simultaneously on single or multiple projects, its data base capacity and response time provide well for even the largest shipyard.

Autoplate 8.1 (Released 1st Quarter 2002)

This new Autoplate product has been developed and updated to be able to work in tandem with Autostruc- ture 1.1, and to import project files from Autoship 8.1.

Autoplate now incorporates the OpenGL Viewer developed for Autostructure, and "Navigator" — a new feature used to access and control project struc- ture (see description of Navigator in Autoship 8.1 sec- tion above). Another new feature is ability to create plates that extend across the center plane (by reflec- tion). Plate boundaries can be surface edges, chines and embedded curve sections. A full range of expan- sion options is available to match fabrication methods, and the output includes plate measurements, pin jigs, templates and strain contours. Dynamic display is incorporated to let the user see the results of the edit- ing compared to the unedited form, and Autoplate also generates shell expansion drawings.

Autohydro 5.3

This hydrostatics/stability component was released in June 2002. Autohydro is a development of the long- successful product used by naval architects around the world, and is also at the core of ASC's on-board stabil- ity software. It performs intact and damaged analyses and produces customized stability reports which are accepted by all major governing approval bodies.

Improvements include summarized reporting of load-

Autopower 3.0

As the resistance and power prediction component, this program provides 12 resistance prediction meth- ods suitable for displacement vessels, planing vessels, semi-displacement vessels and catamarans. Hull para- meters may originate in Autoship, then Autopower's advanced user interface enables optimization based on the available methods. Autopower also provides pro- peller optimization, analysis of 5 models concurrently, editable reports, rapid calculation and output, and a built-in Report Editor.

ASC has concluded co-operation and marketing agreements with two major players in the ship design and construction field: • The Perception suite from Spar USA (http://www.sparusa.com) does cost estimation, mater- ial management, scheduling and work management.

Direct transfer of part information from Autostructure will provide a link into the shipyard supply chain. • AutoPLANT from Rebis (http://www.rebis.com) is an advanced piping design system. Working together,

Autostructure and AutoPLANT provide designers with the ability to incorporate structural-piping design into the structure design drawings — which is much less costly than resolving structure/pipe interference during the build process.

HDW Purchases Topgallant

As part of the implementation of SAP R/3 at the

Howaldtswerke-Deutsche Werft in Kiel, Germany,

Atlantec Enterprise Solutions has been chosen to develop the link from the Tribon Hull shipbuilding software to R/3.

The link is to be developed in close cooperation with HDW's own software house, NIS Norddeutsche

Informations-Systeme GmbH. Using information extracted from Tribon, the Topgallant software sup- plied by Atlantec Enterprise Solutions will prepare data for the ERP system.

The Topgallant solution to be provided will support both the initial transfer of data shortly before the burning start of each block, as well as any subsequent changes to that block during production. Using inter- active tools supplied with Topgallant, all data can be tracked, verified and, if required, modified indepen- dently of Tribon.

The link to be provided by Topgallant will be used for all new construction programs in both the subma- rine and commercial shipbuilding departments at

HDW.

Delmia Granted Research

Funding From U.S. Navy

Digital Shipbuilding Innovation Center (DSIC), which was founded in 2001 with the support of

Delmia Corp.. has been awarded research funding by the U.S. Navy's Office of Naval Research (ONR).

Delmia Software, in conjunction with CATIA and as part of the global Dassault Systems' 3-D PLM offer- ing. will be used in DSIC to model a digital shipyard.

The focus of the project, which is to determine means for reducing the construction costs of the U.S. Navy warships and commercial ships, will be performed in collaboration with the University of Michigan (Ann

Arbor. Mich.).

Entitled "Simulation-based tools to support decision making in industrial policy, ship acquisition, shipyard planning and ship production process improvement," the project's 3-D PLM enables customers to optimize their business processes for engineering, manufactur- ing. maintenance and support, by utilizing collabora- tive workspaces to share a common product, process and resource (PPR) model.
