Hull Design & 3D CAD Modelling

Delivering precise hull forms, complete 3D vessel models, and production-ready CAD drawings for construction and class approval across all vessel types — ships, yachts, offshore units, and marine structures.

What We Offer

3 specialist capability areas

01

Hull Form Design

  • Parametric Hull DesignDevelopment of hull form with controlled key coefficients — block (CB), prismatic (CP), midship (CM), and waterplane area (CWP).
  • Hull FairingClass A surface fairing for smooth, fair lines free of unfair curvature for hydrodynamic performance and plate forming.
  • Bow & Stern OptimisationBulbous bow, transom, and stern form optimisation for reduced resistance at service speed.
  • Lines Plan ProductionOffset tables, buttock lines, waterlines, sections, and body plan for construction.
02

3D CAD & Digital Twin

  • Full 3D Vessel ModelComplete 3D solid model — hull, structure, outfitting, systems — compatible with FEA and CFD.
  • General Arrangement DrawingsMulti-deck GAs showing all spaces, accesses, equipment footprints, and escape routes.
  • Steel Structural DrawingsLongitudinal and transverse structural plans, midship sections, and connection details.
  • Outfit Arrangement DrawingsMachinery room layouts, pipework routing, electrical cable tray runs, and HVAC plans.
  • Digital Twin DevelopmentIntegration of structural, systems, and operational data into a live digital twin for lifecycle management.
03

Production CAD

  • Block & Panel Assembly DrawingsFabrication block definition, seam and butt planning, and assembly sequence drawings.
  • Nesting & Cutting PlansAutomated and manually reviewed plate nesting for material optimisation and CNC cutting output.
  • Weld Procedure Plans (WPS)Joint configuration drawings and weld symbol annotation aligned with class requirements.
  • Pipe Isometric DrawingsSpool drawings for prefabrication and installation of piping systems.
