Sener tools up for Intership


Te vast Intership Project has allowed soſtware supplier Sener to contribute to the development of safer, cost-effective, and environmentally-friendly ships. Clare Nicholls reports.


T


he results of the Intership Project, which aims to improve the competitiveness of European cruise


and ferry shipbuilders, were presented to the European Commission at sessions taking place in Delſt, Holland, in December 2007. Te programme was coordinated by Aker Yards and divided into seven sub-projects. Te rest of the seven shipyards involved comprised Aker’s Chantiers de L’Atlantique facility, Fincantieri, Meyer Werſt, Navantia, Estaleiros Navais de Viana do Castelo, and Flensburger Schifau-Gesellschaſt mbH & Co. Presentations were given for seven sub-


projects, and six discussion tables were arranged to show and debate the results. Soſtware developer Sener took part in one of these tables, carrying out presentations of the new Ship Spaces Management Tool, which was the result of sub-project I-4, Early Design Methods and Tools, a module which was led by Navantia. Sener has played a significant role


within the project, also being one of the main technology providers of sub-project I-2, Collaborative Working Environment Tools and Implementation, spearheaded by Fincantieri, and sub-project V, entitled Modularisation, led by Aker Yards.


Serving project I-2 During I-2, Sener developed a CAD/ PLM integration server prototype (CAD Integration Server-CIS), which integrates the services-oriented architecture with surrounding PML by means of web services, using the HTTP SOAP protocol. The prototype allows basic document management functionality, for which a specified series of generic web services have been developed, such as the types and classes of documents definition, document creation and search, check-in, check-out, and document version creation. To check the system’s viability, Sener

program with ERP, plus PLM systems, SAP, and Windchill, with satisfactory results. To facilitate integration with other systems, this tool allows the import of ship forms in STEP AP216 and IGES formats, as well as exporting components in STEP AP215.


Defining ship spaces As part of sub-project I-4, Sener created a the Ship Spaces Management Tool (SSMT), focusing on the definition of 3D ship spaces, and incorporating features developed to facilitate the compartments of ships among the initial phases of the design. Storing the modelling of ship spaces in a relational database now allows multiple users to access the model. Spaces definition can be carried out,


beginning with existing surfaces, hull decks, and bulkheads of a ship. The definition can be made either on an individual basis (defining each space limit), by subdivision, or using parametric zones. In addition, the tool can automatically


subdivide the existing ship zones, starting in the bulkheads and existing decks. Tese spaces are generated geometrically as solid and limited by trimmed NURBS surfaces. SSMT lays out advanced model and 3D


visualisation functions that facilitate ship compartment definitions. Compartments can be grouped hierarchically by means of trees with different characteristics (evacuation zones, accommodation area), and it is also possible to define user-configurable general attributes to assign different characteristics to the compartments. The new tool contains an integrated


development environment that allows access to compartment trees, including spaces characteristics and attributes either for report generation or the development of specific functions for compartment design tests that meet international regulations. Te system can remove spaces from the initial design phase through macros and parametric objects.


Modularisation tools Sub-project V enabled Sener to develop a series of specific tools to facilitate the use and definition of modules during initial ship design stages. Te aim of the first stage of the subproject was a conceptual study to define module specification in a CAD/CAM system, and in particular in FORAN. During the second stage, the results were applied to an engineroom.
