NAPA 2024

The NAPA 2024 software suite is a comprehensive platform for ship design, leveraging parametric modeling and simulation to optimize vessel performance across the design process, from conceptual design to detailed engineering. Widely used by shipyards, design offices, and classification societies, it supports 3D modeling, finite element analysis (FEA), weight optimization, and compliance checks. Its key strength is a model-driven approach: a single ship model can be reused for multiple analysis tasks, reducing data duplication and improving efficiency.

• Main Modules:
  • NAPA Basic: Ship geometry modeling and preliminary design, supporting hull surface creation and compartment layout.
  • NAPA Steel: Structural design module for interactive 3D structural modeling, supporting classification society rule checks, finite element model export, and weight calculations. Suitable for large vessels like container ships and tankers.
  • NAPA Stability: Stability and loading management, supporting dynamic stability simulations and compliance verification (e.g., IMO standards).
  • NAPA Outfitting: Equipment and piping design.
  • NAPA Hydro: Hydrodynamic analysis, including resistance, propulsion, and wave response.

NAPA integrates with tools like AutoCAD and Rhino and supports API connections with other systems (e.g., ERP or production management systems).

• Technical Features:
  • Parametric Modeling: Uses reference coordinates and topological relationships for rapid design modifications (e.g., adjusting bulkhead positions).
  • Rule Integration: Built-in classification society rules (e.g., DNV, ABS, CCS) for automated compliance checks.
  • Visualization and Collaboration: Interactive 3D interface, supporting team collaboration and VR/AR extensions.
  • Performance Optimization: Supports high-performance computing for complex models like LNG carriers or wind turbine installation vessels.

2. 2024 NAPA Software Updates and Highlights

In 2024, NAPA focused on sustainability and digitalization, releasing several updates targeting green ship design and AI-assisted workflows. Key developments include:

• NAPA Steel Enhancements: Introduced advanced 3D structural modeling tools, tested in collaboration with Hyundai Heavy Industries (HHI). These support an interactive modeling interface. Once a ship model is created, it can be used for rule checks, drawing generation, and finite element analysis. HHI’s department head noted significant improvements in engineer productivity and design quality. Additionally, in collaboration with NTT Data Systems, NAPA Steel integrated with Beagle software via a 3D data interface, enabling seamless design-to-production workflows.
• NAPA Stability New Features: Launched a loading and stability management module for passenger ships, receiving DNV Type Approval. This module optimizes dynamic load simulations and supports stability calculations for alternative fuel ships (e.g., methanol-powered vessels), aligning with IMO 2024 regulations (e.g., carbon emission limits).
• Digital Workshop Integration: NAPA partnered with MES/APS systems (e.g., Huizhou Technology) to extend into production management, supporting end-to-end digitalization from design to manufacturing. In 2024, NAPA emphasized AI-driven optimization, such as automated weight distribution and structural lightweighting, particularly for large container ships.
