Conceptual Development Capability
Advance Surface Ship and Submarine Evaluation Tool (ASSET)
The Advanced Surface Ship and Submarine Evaluation Tool (ASSET) is the US Navy’s primary tool for developing early stage ship designs and determining the impact of new technologies on future Navy designs. ASSET is a family of ship design synthesis programs with a common windows interface, incorporating over 20 years of US Navy design experience. Extensive help and program documentation is included to aid the naval architect in the efficient and effective use of the tool.
ASSET integrates all of the required engineering disciplines to predict the total ship physical and performance characteristics. The design is developed with sufficient fidelity so that the total ship implications of subsystem level design and technology decisions are evident. These decisions and the associated input data are based upon the given mission requirements.
NSWC CD provides the capability to quickly determine a quality ship design based on:
Technology assessments
ROM, concept, feasibility designs
Analysis of Alternatives studies
Design studies where the ship characteristics or performance are an issue
Initial product data models for detailed design and analysis by commercial CAD and other US Navy tools
ASSET includes the capability to connect with any other Windows COM compliant tool to facilitate exchanging data and commands. A primary use of this expanded API is prototyping new design processes in an Excel spreadsheet based application linking to ASSET as the ship design engine. This capability has recently been used to prototype the design of trimarans using the monohull version of ASSET. Recently, this capability has also facilitated use of probabilistic design and analysis techniques, such as Design of Experiments, especially in the early stages of Analysis of Alternatives programs. ASSET provides the capability to exchange product model data with design analysis and CAD applications through its integration with the LEAPS environment.
New design and technology options are added when sufficient definition exists. The designer must have the flexibility to address new design and technology options before a complete definition exists. ASSET facilitates this by allowing the naval architect to insert any new technology into a design by defining its impacts upon the ship in the following areas: weights and centers, required arrangeable areas, electric loads, efficiencies, manning.
