Naval Ship
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
