PURPOSE: An Icebreaker with drilling equipment for breaking ice and an icebreaking method using the same are provided to break ice in various directions by coupling drilling equipment to a motor shaft of an azimuth thruster.;CONSTITUTION: An icebreaker(10) comprises drilling equipment(100). The drilling equipment is protruded from the heading directional bottom of a hull in a ship heading direction. The drilling equipment comprises a drill bit(110), a drilling shaft(120), and a drilling motor(130). The drill bit breaks ice with rotational force. One end of the drilling shaft is mounted on the drill bit. The other end of the drilling shaft is connected to the drilling motor to transfer the rotational force to the drill bit. The drilling motor supplies the rotational force to the drilling shaft.;COPYRIGHT KIPO 2013;[Reference numerals] (130) Drilling motor; (140) Variable speed driving device; (200) Direction control device; (AA) Sea ice
