Sažetak
The aim of the present paper is to investigate a correlation between collision damage parameters, which could improve Monte Carlo simulation of random collision damages and facilitate its implementation into the risk assessment of maritime transportation. The proposed approach is based on the explicit LS- Dyna simulation of the collision between a ferry and an Aframax tanker, as striking and struck ship respectively. Numerical simulations are then approximated by the surrogate model ena¬bling evaluation of damage for different random collision scenarios characterized by striking ship speed, collision angle, collision location and displacement mass. Monte Carlo simulation of random collision scenarios is then employed to obtain histograms of damage parameters that can be compared to IMO probabilistic models. Such approach enables not only comparison of damage size histograms between IMO and numerical simulations but also establishing mutual correlation among damage length, breadth and height. Finally, the established correlation is employed into the IMO probabilistic model of random damage parameters and consequences on probabilistic models of residual ultimate strength and still water bending moments are discussed.
