Abstract: Provided is a method and a system for removal of oil under ice through an opening made into ice. The system includes oil booms extending under ice in two different directions from the opening so as to constitute an angle of less than 180 degrees between each other; an oil collection device placed in the opening; and a propulsion device placed on the level of the lower surface of ice at a distance from the opening in the area of the angle so as to provide a flow directed towards the opening between the oil booms in the area of the angle.

Abstract: Provided is a device for collecting oil contained in ice. The device includes a lifting device fixed for example to a vessel, a cage of separation adapted to be lowered into the water between the ice blocks by means of the lifting device and formed by a box which lets water and oil but substantially no ice, and an oil collector for collecting the oil on the water surface in the space defined by the separation of cage.

Abstract: Provided is a device for removal of oil under ice through an opening made into ice. The device comprises a long rope mop in the form of an endless loop, a propulsion device provided with a deflection wheel for pulling the rope mop substantially straight under ice, a power device provided with a drive wheel for circulation of the loop through the drive wheel and the deflection wheel and a cleaning device for cleaning of the rope mop from any impurities adhered thereto.
