Device, method and vessel for preventing oil damages and alleviating damages
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.
1. An oil combatting boom comprising:
an elongated boom part having a first end connectable to an oil combatting vessel and a second end distal to the first end,
at least one pontoon member attached to the elongated boom part to provide flotation to the elongated boom part on a water system, and
a number of turnable transfer members operably attached to the elongated boom part, wherein
the transfer members include rotatable blade members, and wherein
the blade members of at least some of the transfer members are formed of a flexible material.
2. The oil combatting boom according to claim 1 , further comprising an extension part at least partly arranged inside the boom part in a telescopic manner at the second end thereof.
3. The oil combatting boom according to claim 2 , wherein the extension part includes at least one pivot point to allow the extension point to be pivotally movable in a vertical direction.
4. The oil combatting boom according to claim 1 , wherein the boom part includes at least one pivot point to allow the boom part to be pivotally movable in a vertical direction.
5. The oil combatting boom according to claim 1 , wherein the boom part includes a power device for moving the boom part.
6. The oil combatting boom according to claim 1 , wherein the transfer member has a substantially horizontal axis.
7. An oil combatting vessel which includes at least one oil combatting boom according to claim 1 .
8. A method for collecting oil from an oil-polluted shore area, wherein the method comprises:
(a) equipping an oil combatting vessel with an oil combatting boom according to claim 1 ;
(b) steering the oil combatting vessel equipped with the oil combating boom into a vicinity of the oil-polluted shore area,
(c) extending the oil combatting boom to the oil-polluted shore area,
(d) transferring oil from the shore area into the water by rotating the blade members of the transfer members, and
(e) steering the oil in the water toward a final collection space by rotating the blade members.
9. The method according to claim 8 , which comprises simultaneously steering the oil combatting vessel to travel along the shore area, and continuously transferring oil from the shore area into the water.
10. The method according to claim 8 , which comprises cutting down oil-polluted vegetation growing in the water close to the shore area or in the shore area by rotating the blade members of the transfer members, transferring and cut vegetation into the water together with the oil, and thereafter moving the cut vegetation and the oil toward the final collection space.
11. The oil combatting boom according to claim 1 , the transfer members positioned farthest from the first end of the boom part include blade members formed of a flexible material.
12. The oil combatting boom according to claim 11 , wherein the transfer members positioned closest to the first of the boom part include blade members formed of an inflexible material.
