Abstract :
This study explores the ultimate longitudinal strength of five different sizes of container ships to investigate the impact of considering aged corrosion effects throughout a ship’s life. The typical design life of double oil tankers and bulk carriers, according to the CSR(CommonStructuralRule), is 25 years and approximately 20 years for other commercial ships. In case of containerships, whether corrosion addition is required differs according to classification society with some not stipulating any such requirements.To conveniently define aged corrosion additions for containerships, the corrosion addition requirements for a double hull oil tanker, which has are latively similarmid-ship the section configuration, were applied in this study asaninitial guideline. The ultimate strength of the selected containership, including their longitudinal strength behavior, is investigated in this study to show the necessity of corrosion addition application to containerships and the relevant predictions regarding decreases in the longitudinal strength of new-building container ships after corrosion. The investigation results regarding longitudinal strength reduction and other findings from this analysis of five containerships will be useful in enforcing corrosion addition as a general guide line.
