Abstract: Изобретение относится к ледоведению и ледотехнике и может быть использовано в предупредительных работах для обеспечения более раннего прохода судов к местам проведения грузовых операций, в частности на шельфе замерзающих морей. Способ разупрочнения ледяного покрова заключается в прорезывании щелей во льду, которые заполняются подкрашенной водой. Вода, замерзая, образует вертикальные прослойки. В весеннее время за счет проникающей в лед солнечной радиации подкрашенный лед в прорезях прогревается вплоть до расплавления, благодаря чему облегчается механическое разрушение ледяного поля при вертикальном воздействии.
