 llow"><br>During the interactions between ice covers and ship/offshore str
 uctures\, the ice cover is broken into small fragments. The breaking patte
 rn of ice cover is dominated by the geometric properties of ship/offshore 
 structures\, besides the ice parameters of thicknesses\, strengths\, drift
 ing velocities. Meanwhile\, the breaking pattern of ice cover has a close 
 relationship with the ice loads on the structures. To research the propert
 ies of ice loads\, \, the breaking patterns of ice covers and the ice load
 s during the actions on the ship hulls and the fixed jacket platform piles
  are concluded by the field observations in the Antarctic navigation and t
 he Bohai Sea\, respectively. Moreover\, the discrete element method (DEM) 
 with bonded spheres is also adopted to model numerically the breaking patt
 erns of ice cover. The influences of the breaking patterns of ice cover on
  the magnitude and frequency of ice loads are discussed based on the DEM r
 esults. </a>The field data and the DEM results were compared to determine 
 the relationship between the breaking length of ice cover and the ice load
 . </span>  &nbsp\;  <br><span><b><br>Keywords</b>: Ice cover\, Breaking pa
