초록

Purpose: The purpose of this study is to propose retrofit measures for KDX-II KVLS hull crack, also, enhance safety and quality of ship. Also, this study suggest to how to retrofit about hull crack of the ship and how to improve operability of the ship. Methods: Retrofit measures of KDX-II KVLS hull crack reach a conclusion through global structure analysis and fatigue analysis. Concerned about thermal deformation due to welding around the KVLS, in addition to, verify to safety of KVLS. Results: Based on result of global structure analysis establish retrofit measures for KDX-II KVLS hull crack. Additionally, through fatigue analysis establish final retrofit measures. The results of retrofit measures are allowed both stress level and fatigue life. Conclusion: Retrofit measures for ship hull crack based on global structure analysis and fatigue analysis improves operability and quality of the ship. Especially, KDX-II ship is the best battleship in our country. Considering the importance of KDX-II, this study improves both Korea navy's combat power and ability to carry out the mission.
