Abstract
Ship transport is growing up rapidly, leading to ship's size increase, particularly for container ship. The last generation of container ship is now called Ultra Large Container Ship (ULCS). Due to their increasing sizes (LBP close to 400 m nowadays), they are more flexible and their structural natural frequencies may fall into the range of encounter frequencies. Therefore, waves may induce springing vibration of the whole hull girder, which will increase the fatigue damage. The purpose of the paper is to present a practical and reliable spectral fatigue damage methodology based on 3D linear hydroelastic model using 3DFEM and 3DBEM (‘
