Composite materials

Production

Our facilities are purpose-built and equipped for optimized production flow of larger military vessels and civilian passenger and crew transfer vessels, as well as, composite components, or production of smaller boats in larger series in combination with other large and advanced products.

Our bespoke facilities accommodate design, production, testing and servicing of large structures and vessels in Fiber Reinforced Plastic (FRP) sandwich material, and is equipped to ensure high volume, quality manufacturing process.

We evaluate the processing needs of the materials at the initial stage of every project, and customize the best solution as part of a lifecycle analysis, depending upon the intended function of the component or structure.

Purpose-built production facilities for Umoe Mandal

Purpose-built facilities

  • Total area: 41.000 m2
  • Indoor floor area: 16.000 mincluding offices, production hall, outfit hall, workshops and warehouse

  • Traverse cranes
    • 4 x 15 MT SWL in production hall
    • 1 x 12,5 MT SWL in the outfit hall
  • Systems for ventilation, heating and humidity designed specifically for FRP production
  • Deep-water quay: 6 m depth

Advanced production methods

We utilize a number of tools and techniques when designing, manufacturing and testing composite structures and vessels. We apply a number of calculation methods:

  • Computational Fluid Dynamics for aerodynamic performance predictions and load calculations
  • FEM analysis (ANSYS) for load calculations
  • Polyworx for flow simulation and complex vacuum infusion processes
  • Scaled model testing

We have solid expertise in VARTM manufacturing:

  • Resin Transfer Molding (RTM)
  • Vacuum Assisted Resin Transfer Molding (VARTM)
  • Hand layup – Open Molding Process
  • Filament winding
  • “Pre-preg” and “Wet-preg”

Typically, all large components are vacuum infused, while high-temperature RTM is used for smaller, aerodynamic components.
