NAPA’s structural design solution, known as NAPA Steel, revolutionizes the entire process, starting from the project’s inception and continuing through to the detail design stage. By replacing traditional 2D drawings with our versatile NAPA 3D product model, the design process becomes more streamlined. Transitioning to the NAPA 3D model allows for earlier strength checks and more accurate weight estimations, promoting enhanced collaboration across various disciplines. The key benefits include optimized design, reduced lead times and project risk, and increased productivity in both ship design and production.
Benefits
Intuitive and efficient design with specialized 3D modeling tool
NAPA Designer offers a highly intuitive and efficient 3D modeling experience designed specifically for ship structural design. It facilitates rapid model creation through automation technologies and adaptable design changes, incorporating existing naval architectural models like hull form and compartments.
This tool ensures a versatile design experience tailored for ship designers, distinguishing it from other general CAD systems.
Streamline Finite Element (FE) analysis integrated with 3D design
Our cutting-edge auto-FE mesher, built on the same platform as 3D structural modeling, streamlines strength assessments. NAPA Designer’s tools automatically optimize the as-built 3D model into high-quality FE models for diverse analysis purposes, compatible with various external FE analysis software. With an integrated, early-available, and highly adaptable 3D structural model, achieving optimal, reliable, and cost-efficient designs becomes achievable.
Seamless integration with classification society rule check tools
NAPA’s structural design solution integrates seamlessly with major classification societies’ rule check software, including:
Bureau Veritas Mars, DNV Nauticus Hull, ABS Eagle UDM, ClassNK PrimeShip-Hull, Lloyd’s Register RulesCalc, Korean Register SeaTrust-HullScan and China Classification Society Compass SDP.
NAPA Designer supports the full specification of the Open Class 3D Exchange (OCX) standard, which is a testament to our commitment to industry collaboration and further innovation.
NAPA Drafting: Effortless drawing creation with best-in-class user interface
By leveraging AutoCAD technology, NAPA Drafting offers a best-in-class user interface for efficient drawing generation. It allows for easy extraction of 2D sections and the auto-add annotations from the NAPA 3D model in a short time. As the design progresses in its 3D form, NAPA Drafting consistently maintains and updates the 2D drawings, ensuring a seamless connection with the 3D model. This solution maximizes the benefits of 3D design in a workflow requiring 2D drawings for communication and approval.
Accurate numeric outputs from early design
Leverage NAPA’s 3D product model for accurate numeric outputs from the initial stages of design.
- Steel weight and center of gravity calculations
- Bill of materials for early material estimation
- Welding lengths and production cost estimation
- Painting area and coating estimation
- Insulation material estimation
- Optimal block division studies
- Any calculated data derived from 3D model
All outputs are auto-generated and customizable to suit your specific requirements.
Efficient collaboration via advanced 3D CAD interfaces
NAPA structural design solutions integrate seamlessly into the design process by interfacing with other software in the industry. Numerous general CAD formats are supported to import and export data from NAPA to support for example outfitting and to share information with the whole design organization. In addition, there are production design software-specific interfaces to:
- CADMATIC Hull & Outfitting
- Aveva Hull & Outfitting
- Hexagon Smart 3D
