Depends on how much ocean and how deep.  If it is in effect all ocean many   
   kilometers deep, the ocean will stay liquid all the time and you will have   
   constant large evaporation on the sunlit side and constant large rain and snow   
   fall on the dark side.      
   The dark side MIGHT have a large floating ice pack, but ocean currents would   
   tend to be deep toward the sunlit side and shallow toward the dark side.     
   Heat causes expansion of water and so lower density, more salt or lower   
   temperature higher density.     
   That will drive current flows, local topography will influnce all that.
