Onshore structures critical load and selection of design solution

In the paper the analysis of the kinetic energy absorption of the ship while putting to the onshore structure is presented in a variant when the total energy is absorbed by elastic fenders and in a variant when the total ship kinetic energy is absorbed by fenders and onshore structure through their deformations without any effect of soil and respecting the deformability of soil, that is, the energy delivered into the soil. Great differences between the mentioned approaches are evident concerning the distribution of displacements and internal forces in the structure which is particularly expressed at the computation of pile ultimate bearing capacity. A rationalization of the force reduced by 30% approx. as compared to the standard solutions provides an absorption of the ship kinetic energy while putting ashore at a speed greater than permited.
