Abstract
Abstract The present invention relates to an improved vessel for removing oil from water surfaces, said vessel comprising means for carrying out both a mechanical and a chemical removal of the oil. Thus, in the first part of the vessel there are means for taking in water and oil and for the separation thereof by a skimming device. In the rear part of the vessel which part communicates with said first part over an adjustable overflow means, are arranged means for spraying chemicals onto the overflow from said first part. An outlet wherein a propulsion means for the vessel is placed, is located in the rear part thereof.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A vessel for the removal of oil on water by combined mechanical and chemical means, said vessel comprising an intake portion at the forward part of said vessel, a separation tank connected to said intake portion, said separation tank having a rear end and a skimming device for oil disposed adjacent said rear end and extending across said tank, said skimming device being in the form of a dish, a vertically extending partition wall extending across said tank and being disposed between said rear end and said skimming device, said partition wall having a portion spaced from the bottom of said tank to define a passage leading to the rear edge of said separation tank, said rear edge of said separation tank having a verTically adjustable weir, a suction chamber being provided beyond said rear edge of said separation tank, said suction chamber including a dosaging device for supplying an oil removing agent, said suction chamber having an outlet leading to a propulsion device provided for moving said vessel.
Claim 2
Dependent Claim
169 words
A vessel for the removal of oil on water by combined mechanical and chemical means, said vessel comprising an intake portion at the forward part of said vessel, a separation tank connected to said intake portion, said separation tank having a rear end and a skimming device for oil disposed adjacent said rear end and extending across said tank, said skimming device being in the form of a dish, a vertically extending partition wall extending across said tank and being disposed between said rear end and said skimming device, said partition wall having a portion spaced from the bottom of said tank to define a passage leading to the rear edge of said separation tank, said rear edge of said separation tank having a verTically adjustable weir, a suction chamber being provided beyond said rear edge of said separation tank, said suction chamber including a dosaging device for supplying an oil removing agent, said suction chamber having an outlet leading to a propulsion device provided for moving said vessel.
Claim 3
Dependent Claim
49 words
A vessel as claimed in claim 1 wherein said intake portion is provided with a vertically adjustable weir wall having an upper edge whereby the size of the intake may be adjusted by setting said upper edge of said weir wall at a selected depth under the water surface.
Claim 4
Dependent Claim
37 words
Vessel according to claim 1, characterized in that it is provided with sweeping arms, which extend horizontally in the normal direction of movement of the vessel and are fastened one on each side of said intake portion.
Claim 5
Dependent Claim
17 words
Vessel according to claim 1, characterized in that said skimming device is adjustable in the vertical direction.
Claim 6
Dependent Claim
22 words
Vessel according to claim 1, characterized in that said skimming device is connected to an oil storage tank through a pumping device.
Claim 7
Dependent Claim
59 words
Vessel according to claim 5, characterized in that between said oil storage tank and the skimming device there is inserted a container which is located so that oil from the skimming device may flow freely down into said container, and so that oil from the container may be lifted to the storage tank by means of said pumping device.
Claim 8
Dependent Claim
24 words
Vessel according to claim 1, characterized in that the dosaging device has a discharge orifice located in the upper part of the suction chamber.
Claim 9
Dependent Claim
36 words
Vessel according to claim 1, characterized in that the bottom of the suction chamber has an opening which may be closed by a pivoted cover, said opening being adapted to the passage of additional propulsion water.
