Results of observations show that when icebreakers operate in hummocked ice by overrunning the ice, jamming often results. The time lost in freeing the ship from the jam sometimes is nearly 50% of the overall time required to break a sector. The stress caused by a jam can be determined by the tested method of measuring the degree to which the hull breaks water and the trim.
