In work the fact of an essential increase of structure of cargo fleet of the internal and mixed a river sea navigation by vessels with nonconventional forms hulls is noted. On the basis of these CAE tests the analysis of nature of contact of such vessels with the water ice environment at the movement in the ice channel is carried out. Qualitative features of such contact of bulbous vessels with ice cakes and small ice cakes are noted. Special attention is paid to a research of influence of bulbous nasal points of different types on change of level of longitudinal ice hull loads and distribution of ices in a zone of their propeller systems. Statistical processing of the obtained experimental data on impact assessment of ice, dynamic and constructive factors on inertial characteristics of vessels with nonconventional forms hulls is carried out. The quantitative predict of such influence in the form of an empirical method of assessment of ice inertial characteristics of the studied fleet is given.
