Assessment of global vertical loads in damaged ship

The present work is meant to investigate wave-induced global loads of a ship in realistic flooding conditions, while developing a code for automated hydrodynamic simulations and computation of vertical wave induced global loads. The scenarios investigated are represented by water ingress into the starboard ballast tanks for collision damage cases and both starboard and port side tanks for grounding. Seakeeping computations are performed for 8 damage scenarios and 1 intact condition, each corresponding to different changes in displacement, trim and heel. For each of them, response amplitude operators of vertical motions are calculated using a potential linear 3D panel hydrodynamic code WAMIT in the frequency domain. The wave-induced global loads are computed using a code for post processing developed in MATLAB. The obtained results are compared with others already published. For some cases, the results show significant variations in the global loads with respect to the intact ship.
