Abstract

The invention relates to an oil combating boom (1), which comprises an elongated boom part, which at its first end is connectable to an oil combating vessel (10). At least one pontoon member (5) and a number of turnable transfer members (6) equipped with rotating blade members (9) have been arranged in connection with the elongated boom part. The invention further relates to a method for collecting oil from a polluted shore area, in which method an oil combating vessel is steered to the vicinity of the shore, the oil combating boom (1) is arranged to extend onto the polluted shore area, oil is transferred from the shore area into the water and steered in the water towards the final collecting space (11) by rotating the blade members (9) of the transfer members (6). Also disclosed is a device and a method for separating oil from ice blocks and collecting oil from an icy water system, in which a floatable frame with a separation grate (18) presses ice blocks (16) at least partly under the water surface in order to separate oil from ice blocks. Support part (19) is pivotably connected to the separating grate and the frame for altering the elevation and angle of the separating grate in relation to the level of the water surface of the water system.

Abstract

The invention relates to an apparatus and method for collecting material from a water system, especially from the surface or close to the surface of a water system. The method comprises - maneuvering an apparatus with a cargo space in a water system; - conducting water, present in the surface and close to the surface of the water system, and material therein to be collected, in response to the vessel's advancing speed through a collect opening, located in a fore section of the apparatus in its traveling direction, into the cargo space; - conducting water from the cargo space back into the water system through an exhaust opening in the cargo space's bottom.
