Introduction
Ship Plant technology center has been carrying out structural safety assessment of commercial and naval ships and technical development activities continuously.
Structural safety analysis, where consist of direct calculation for wave load through ship motion analysis and probability statistical analysis, is to identify the
vulnerable areas of target ship structure from analysis and provide reinforcement method for the ship structures.
The analysis method for naval ship’s structural safety assessment includes whole ship structural analysis and spectral fatigue analysis, and is shown in the
procedure given below
- Hydrodynamic model
- Sea-keeping analysis
- Stochastic analysis
- Design waves Design Loads
- Global structural model
- Fine mesh, if necessary
- Global structural analysis
- Yielding, Buckling Evaluation
- Fine mesh (Thickness)
- Stochastic analysis
- Global structural analysis
- Fatigue life evaluation
