One2three Naval Architects: Designers of Monohulls, Catamarans and Trimarans

Structural Design

One2three staff have extensive experience in designing lightweight aluminium structures for high-speed craft, with over 170 vessels designed and no reported structural failures. A typical One2three structural design:

  • Utilises specially designed aluminium extrusions for weight saving and rigidity
  • Meets the standards set by major classification societies

One2three use the following to analyse vessel structure:

  • Multiframe for three-dimensional interactions
  • Finite-element analysis on the global loads for large vessels

One2three also have experience designing in steel and composites.

Production-Oriented

One2three focus on designing for production in order to minimise shipyard cost and time. One2three use Workshop in the initial stages for:

  • Hull-stringer fairing
  • Development of hull-shell plating

Detailed construction design is carried out using the leading-edge ShipConstructor suite of software. The benefits of this include:

  • A high level of accuracy by checking complex three-dimensional interactions
  • Output of three-dimensional production drawings and bills of materials
  • Automatic nesting which gives significant savings on materials through optimisation of the nests
  • Modularisation of vessel construction
