METHOD OF AND APPARATUS FOR ICE DISAGGREGATION

摘要

METHOD OF AND APPARATUS FOR ICE DISAGGREGATION An ice cutter movably mounted on a marine structure for cutting encroaching ice floes or ice sheets. A cutter blade. is mounted on the structure so that it may be conveniently moved into position on the structure toward which the ice is moving. Acoustical energy is imparted to the cutter blade which in turn is positioned adjacent the encroaching ice and moved relative to the ice in a manner to cut out a path of unconsolidated ice so that the floe may pass the marine structure without applying destructive forces to the structure.
