A skimmer for removing a layer of oil floating on a surface oil contaminated water which subsequently concentrated and separated in an oil water separator which removes tramp oils or other fluids, such as hydraulic oils, with specific gravity less than that of the operating fluid are required to be removed from operating fluid such as water, lubri-coolants or other liquids. The skimmer supplies concentrated oil water composite fluid to a separator apparatus designed for use in industrial applications in which unwanted tramp oils or other fluids, such as hydraulic oils, with specific gravity less than that of the operating fluid are required to be removed from operating fluid such as water, lubri-coolants or other liquids.

A floating weir skimmer comprises a collecting box (10), a weir plate (11) and an inner buoy (5). Said collecting box (10) comprises a baffle plate (3) and a trough (1). A guide rail (6) is arranged inside said trough (1). An inner buoy (5) is arranged inside collecting box (10), and a guide pulley (14) is arranged on said inner buoy (5), enabling said inner buoy (5) to slide on said guide rail (6). A supporting member is further arranged on said inner buoy (5). One end of said weir plate (11) is carried by said supporting member, and the other end is in rotation connection with said trough (1).

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.

A method for collecting a surface layer of a liquid into confined area, method including forming confined area by means of wall structure and moving some of surface layer of liquid into confined area by means of a flow of air directed into confined area through an opening made into wall structure of confined area so that amount of substance in surface layer of the liquid increases in confined area in comparison with surroundings. The bottom edge of opening made into wall structure of confined area is arranged to be below surface level of liquid outside confined area whereas its top edge is substantially above surface level of liquid outside confined area. The surface level of liquid inside confined area is arranged to be kept substantially on same level with surface level of liquid outside by providing a continuous liquid flow connection through lower portion of confined area into surroundings.

An apparatus for continuously removing an oily pollutant from polluted water includes an absorbent unit and a suctioning unit. The absorbent unit is made of a hydrophobic and oleophilic porous material and is able to absorb and to separate the oily pollutant from water when the absorbent unit is placed in the polluted water. The suctioning unit is coupled to the absorbent unit and is operable for providing a suctioning force to the absorbent unit so as to continuously remove the oily pollutant absorbed by the absorbent unit. A method for continuously removing the oily pollutant from the polluted water is also provided.

Disclosed is a system for removing floating waste which includes a storage filter support that has a conical shape and tapers to a lower end thereof when it is installed for use and a storage filter that is inserted into the storage filter support from above. The system further includes a pump and an internal impeller when the system is a model to be used in water with zero velocity. Alternatively the system further includes an internal impeller and a speed increaser when the system is a model to be used in water with a velocity that is not zero. The speed increaser is installed in the storage filter support and drives the internal impeller.

A system for collecting oil from mixed ice and water conditions. The system uses suction pods that are welded along the hull of a vessel. These pods are elongated vertically and have a vertical slit opening that allow oiled water to enter into the suction box during wave action. Each vertical opening is covered with stainless steel mesh layers to inhibit smaller ice from entering the suction box. Inside each of the suction boxes is a horizontal floating suction bar that is connected to a flexible suction hose. The suction bar is free floating within the suction box so that collection always occurs at the water's surface. The collection line from the suction box leads to a collection and separation area. The suction boxes are protected by heavy-duty metallic bumper that are welded to the hull to protect the suction box arrays.

Systems and methods capable of processing floating solid materials recovered from a body of water on a vessel are disclosed. In some embodiments, at least first and second debris processors are provided. The first debris processor may be disposed on the vessel between at least one intake opening and at least one discharge port, both of which are fluidly coupled to at least one chamber of the vessel. The second debris processor may be disposed between the first debris processor and the discharge port(s).

The present invention relates in a first aspect to a liquid removal device, and in a second aspect to a method for removing a liquid, such as oil or an algae slurry, from a surface of water. The device comprises a circumferentially extending flexible wall element defining together with a bottom part a suction chamber for receiving the liquid. A floater body is sealingly connected to the flexible wall element at an upper edge of the latter, and is able to effectuate a movement in a direction that is substantially perpendicular to the surface of water. The floater body has a circumferentially extending outer member and an inner member. The inner member is adapted to receive a buoyant force exerted by the liquid contained in the suction chamber. The outer member has an upper circumferential edge for receiving the liquid.

A system for removing contaminants from a body of water, may include a vessel, having contaminant cleanup and recovery equipment that may have at least one intake port capable of removing floating contaminants from the body of water to be transported to the recovery vessel. The system may further include a first towboat and a second towboat. The system may also include a first containment boom capable of being connected to the first tow boat and to a starboard side of a vessel. The system may also include a second containment boom capable of being connected to the second tow boat and a port side of the vessel, such that during operation the first and second towboats extend out from the vessel such that the first and second containment booms gather the floating contaminants from the body of water and channel them to the at least one intake port.
