CA 2750964

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.

L'invention concerne une flèche (1) anti-marée noire comportant une partie de flèche allongée, pouvant être reliée par sa première extrémité à un navire (10) anti-marée noire. Au moins un élément (5) de ponton et un certain nombre d'organes orientables (6) de transfert équipés d'organes (9) à pales rotatives sont disposés en liaison à la partie de flèche allongée. L'invention concerne en outre un procédé de ramassage du pétrole à partir d'une zone littorale polluée, comportant les étapes suivantes : un navire anti-marée noire est piloté jusqu'au voisinage du rivage ; la flèche (1) anti-marée noire est disposée de façon à s'étendre jusque sur la zone littorale polluée, du pétrole est transféré de la zone littorale dans l'eau et dirigé dans l'eau jusqu'à l'espace (11) de collecte finale en faisant tourner les organes (9) à pales rotatives des organes (6) de transfert. L'invention concerne également un dispositif et un procédé de séparation du pétrole de blocs de glace et de collecte de pétrole à partir d'un système d'eau glacée, où une armature flottante munie d'une grille (18) de séparation enfonce des blocs (16) de glace au moins partiellement sous la surface de l'eau afin de séparer le pétrole des blocs de glace. Une partie (19) de support est en liaison pivot avec la grille séparatrice et l'armature afin de modifier l'élévation et l'angle de la grille séparatrice par rapport au niveau de la surface de l'eau du système d'eau glacée.
