Abstract

CSR for bulk carrier has been required 25 years operation life in North Atlantic condition. As the fatigue life requirement of ship structure is increased it is necessary to study to satisfy the fatigue life which is much severe. Therefore from the fatigue analysis, especially fatigue strength for double bottom & lower stool connection area is not enough. To satisfy the fatigue life, it needs to increase double bottom strength or insert thicker plate. In this study, the consideration though structure modification have been doe with 81K bulk carrier and to find the solution of fatigue problem.
