Data underlying the publication: Damage probabilities to power system equipment

In order to acquire the precise basic event(BE) probabilities of the damage tree mode, we employed acoustic-solid coupling to simulate underwater explosions on large-scale surface ships under 185 distinct working conditions. The ship equipment deformation was compared with the threshold specified in the BV043/85 standard. Deformation exceeding 4.3 cm is classified as damage. The damage probability of each piece of equipment in the power system (i.e., the damage probability of each BE in the damage tree) was determined based on the simulation results obtained under multiple sets of conditions. As the deformation of the power system equipment exceeds the deformation threshold during the shock wave loading phase, the additional shock of the bubble jet flow on the equipment deformation was not considered.
