Structural Engineering & FEA

Comprehensive structural engineering from class rule-based scantling design through global and local FEA, fatigue assessment, buckling analysis, and specialist offshore and special structure engineering.

What We Offer

3 specialist capability areas

01

Classification Rule-Based Structural Design

  • Scantling DesignPlate thicknesses, stiffener sizes, and primary member scantlings per class rules (LR, DNV, BV, ABS, RINA, NK, CCS).
  • Hull Girder StrengthHogging and sagging bending moment and shear force checks for vertical and horizontal hull girder loads.
  • Local Strength CalculationsPlate panel, stiffener, and primary member assessment under hydrostatic, tank, and deck loading.
  • Fatigue Assessment (Rule)Rule-based fatigue screening of structural details and weld toe locations.
02

Finite Element Analysis

  • Global FEA ModelFull-ship finite element model for global structural response under wave-induced and operational loads.
  • Local / Fine-Mesh FEAHigh-fidelity local models at stress concentration zones, connections, and structural discontinuities.
  • Fatigue Life Assessment (FEA)Spectral fatigue analysis using wave scatter data and stress transfer functions.
  • Buckling AnalysisPanel and column buckling assessment including imperfection sensitivity and post-buckling reserve.
  • Impact & Collision AnalysisCrashworthiness assessment for berthing, ice loads, or accidental flooding events.
  • Thermal & Thermo-Structural AnalysisStructural response under temperature gradients for exhaust uptakes, LNG containment, and fire scenarios.
  • Vibration & Resonance StudyStructural natural frequency analysis and resonance avoidance for propulsion and machinery excitation.
03

Offshore & Special Structures

  • Jacket / Monopile Structure DesignPrimary steel for fixed offshore platforms, wind turbine foundations, and bridge piers.
  • Topside Structural EngineeringModule support frames, skid structures, crane pedestals, and helideck design.
  • Mooring System Structural AnalysisChain table, fairlead, and attachment point assessments under mooring loads.
  • Riser & Conductor AnalysisStrength and fatigue assessment of risers, conductors, and subsea structures.
