Regulation of Ice Loads Acting on the Vertical Side of a Ship Nipped in Ice

The article presents the methodology for regulating the ice loads on the vertical side of a ship nipped in ice, taking into consideration the ice compression strength distributed non-uniformly through thickness in the direction parallel to the ship side surface.
As compared to methods used before, the presented method of ice load modelling during vertical side of a ship nipped in ice suggests ice destruction by bending. The method accounts for the finiteness of load area length and assignment of a load area height less than the ice thickness. The design data show satisfactory coincidence with the data set in the “ice pressure – load area” coordinates.
Further improvement of the model requires a model test of large ship side structures to be followed by a full-scale test.
