NAPA and ABS develop Safehull Express

26 Feb 2004

The ongoing collaboration between Napa Steel in Finland and ABS has culminated in the recent release of a new version of SafeHull, called SafeHull Express, which will be used for the design and assessment of ship structures in accordance with the ABS rules.

The joining of forces has resulted in the integration of a complete initial strength assessment system into shipyard production processes and is the first time such integration has been achieved. The fundamental benefit of integration is that a single 3D ship model can be used consistently in various system environments, which makes the design-to-production process one continuum. The same 3D model can be utilized throughout the initial and structural design stage and the production process. The seamless exchange of data between NAPA Steel, ABS rules and FEM analysis, combining the basic design needs into one package, will speed up the design process considerably.

The 3D ship models created in SafeHull Express can be directly utilized in the NAPA system for further refinements by creating a 3D ship model containing information used for rule calculation and finite element analysis. This model is fully compatible with the NAPA Steel and NAPA compartments used for other design disciplines at shipyards.

SafeHull Express provides easy-to-use templates for defining the geometry and scantlings of the main hull structures. The graphical user interface of SafeHull Express, such as templates and the main window, has been created by using NAPA?s built-in tools and functions. Utilization of the NAPA system features in the development of SafeHull Express was facilitated by means of the NAPA Application Programming Interface (API), which gives external programs direct access to the NAPA database and functions on the software level. A very important part of SafeHull Express is the workflow control, which is based on the NAPA Manager. The topological functions of NAPA play a central role in idealizing the actual structure into a simplified model suitable for finite element analysis.

Together NAPA and SafeHull Express provide a user-friendly software environment for designing ship structures and verification with the ABS rules can be performed efficiently as part of the ship design process. This software brings the benefits of 3D to the earliest stages of the design cycle enabling more accurate estimates of material and construction costs, thus helping shipyards to prepare bidding contracts more cost-effectively, while also helping to speed up the design process. The company claims its program is the only ship design system on the market that has been developed specifically for initial and basic ship design. This has contributed to NAPA?s present position as something of an industry standard among shipyards in Europe and teaming up with SafeHull Express can only enhance NAPA?s role.
