Modern product development technology and methods can have a huge impact on ship lifecycle today. That’s where Siemens PLM Software comes in. NX Ship Structure is a performance-proven application that provides a disciplined yet familiar step-by-step design process for developing ships.

SHIP DESIGN AND MANUFACTURING

shipbuilding1NX Ship Structure software provides a focused environment for modeling and manufacturing the structure of a ship. NX Ship Structure enables the user to conceptualize and model the surfaces and landing curves of the hull, decks, transverse and longitudinal bulkheads. It provides the user with tools to easily create and detail the plates and profiles that make up the structure. It also enables development of the production planning and generation of the structural manufacturing data.

Modern product development technology and methods can have a huge impact on ship lifecycle today. That’s where Siemens PLM Software comes in. NX Ship Structure is a performance-proven application that provides a disciplined yet familiar step-by-step design process for developing ships.

More than a suite of integrated CAD, CAM and CAE applications, NX goes beyond individual and departmental productivity to improve efficiency in the overall process and at each step in the lifecycle. A comprehensive solution, NX is built on an open foundation and advanced technologies that directly support initiatives to transform business processes. NX is fully integrated with Teamcenter® sofware, the world’s leading PLM system, which ensures that all data on every part and component is fully documented and managed.

Ship structure workflow

NX Ship Structure was developed to support the normal ship structure workflow. A ship structural designer:

  • Brings in the hull surface and defines the outer shape of the superstructure
  • Creates a reference model including:
    • Define the ship envelope in 3D spaceshipbuilding2
    • Construct datum planes along the X,Y and Z axes
    • Define the decks (planar or non-planar) based on the Z datums
    • Define transverse bulkheads based on the X datums
    • Define the longitudinal bulkheads (planar or nonplanar) based on the Y datums
    • Construct longitudinal seam and stiffener landing curves
      • Define the major sections or blocks of the ship
      • Create and detail the plates, stiffeners, pillars and edge reinforcements within each section
      • Create structural drawings
      • Generate structural manufacturing data including:
        • Plate bending templates
        • Profile inverse bending curves
        • Added material and shrinkage
        • Marking lines
        • Roll lines - Unfolding
        • XML export

QUALITY CONTROL 3D

Coordinate Measuring Optical measuring technology and full-field surface measurement systems have become a standard tool within virtually all industries. The measurement data from these GOMs measurement systems is now an indispensable tool for quality control in modern product development and production processes chains.

  • Improvement of inspection processes
  • Uniform quality standards for producers and suppliers
  • Shortening evaluation and inspection times
  • Reliable, traceable results
  • Complete and uniform quality controlshipbuilding3

Reverse Engineering for Repair and Overhauls

Today an intelligent combination of knowledge, experience and craftsmanship is required to make ship construction and maintenance successful, safe and financially viable. Precision and cost-efficiency in the shipbuilding industry can be enhanced with high-end CAD programs and optical measurement systems. GOM's TRITOP digital measurement system supports the rapid manufacturing of spare parts with modern CAD/CAM systems and CNC machines, reducing the time ships spend in dry dock from months to just days. Optical 3D metrology from GOM is used to improve the efficiency and precision of repair and reconstruction work in this sector.

Hull Assemblies and Interior Compartments

Using GOM's TRITOP system represents not only a major breakthrough in efficient and accurate 3D modeling of hull assemblies. The system measures not only the outside body shell but also generates measurements on small interior compartments that are not readily accessible. Since spaces within the ship's hull are often extremely narrow, obtaining reliable measurements can be a major challenge. However, GOM systems can be used to create a 3D design of the compartment geometry within a few hours. The 3D data is then used as direct input for CAD systems, making units easy to design, build and integrate smoothly into existing compartment structures.
