Global Wave Loads in Damaged Ship

Wave-induced global loads of a damaged ship in realistic flooding conditions are investigated in present paper. A code for automated hydrodynamic simulations and computation of vertical wave induced global loads is created. 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, transfer functions of vertical motions are calculated using a potential linear 3D panel hydrodynamic code WAMIT in the frequency domain. The waveinduced global loads are computed using a code for post processing developed in MATLAB. Validation of results is performed by comparison with already published studies. Comparison of intact and damaged ship results indicates that for some cases, the global loads of damaged ship are considerably different compared to the intact ship.
