 imagine a excavator without a counterweight or tracks mounted to the forecastle  of the ice breaker.  so it can be used for various things like launching and recovering small crafts and cargo.. but it can also reach over the bow and extend down below the water line and out in front of the ship .. a hot high pressure water line from the engine room is routed to the boom.. with a straightened stream nozzle on the end of the excavator arm.. this could be used to cut icebergs like was shown in the first scene of this video into pieces.  it could also be used when ice breaking. cutting thru the ice in front of the bow.. or swinging back and forth cutting an S shape thru the ice during forward ice breaking.  since the boom will extend below the sea surface. it could also be used to shoot high pressure hot water at submerged sections of ice bergs to get them to tip or split..  And the Louis St. Laurent - the Canadian governments largest ice-breaker - comes to a dead stop on a sheet of contiguous ice.  The LSL was designed and built in the early 60's.  Even though she's had bubblers installed, it didn't do he a bit of good.  At 11,000 tons, she's pretty light for a Class 4.  She's a thirsty beast - you can see her rise out of the water as she's under-weigh.
