| Abstract: | A methodology to assess the time-variant reliability of the primary ship structure with hull girder degradation of corrosion is analyzed. The reliability function is calculated at discrete points during the ship's life. A sample calculation is performed for the reliability of a bulk carrier comparing with the present practice and traditional one. And it is shown that, whenever degradation is present, the time dependent reliability calculated with the present practice shows more accurate dynamic result towards the end of the ship's life. |
