The present disclosure is directed to providing a toothed conveyor belt type oil recovery device including: a recovery conveyor which is rotates in such a way that a continuous track rotates, the recovery conveyor having multiple teeth made of a hydrophilic material on an outer surface, the recovery conveyor having one side positioned in water in which oil is spilled to recover the oil while feeding the oil into a space between the adjacent teeth by the rotation; and a separation unit which holds an oil separating liquid, and is positioned on the other side of the recovery conveyor to separate the oil from the teeth while the oil separating liquid is fed into the space between the adjacent teeth by capillary suction when the teeth move on to the oil separating liquid on the other side of the recovery conveyor by the rotation of the recovery conveyor.

A device having a funnel structure (connected to a separating arrangement by a base pipe is disclosed. The base pipe is horizontal and arranged between the funnel structure and the base pipe. The base pipe is also a vertical suction pipe. The device includes a pressure pipe which is parallel to the base pipe. The funnel structure is slightly below the water surface. In operation, water and floating waste pass over the edges of the funnel structure and swirl into the suction pipe. A jet of water may be injected through the pressure pipe to the base pipe. A flow gradient may then be formed in the base pipe and the differently sized waste objects may separate. If the water contains liquid waste, the speed of the water jet may be adjusted in such a way that the liquid waste and water do not form an emulsion.

Systems, methods, and apparatuses for detecting and collecting fluids released into a body of water are disclosed. Particularly, detection and collection of a fluid released during a petroleum exploration or production operation are disclosed. A released fluid may be detected using sensors on a submersible vehicle (SV) or a plurality of SVs operating in concert. A detected released fluid is collected in storage tanks onboard of the one or more SVs or in an external tank coupled to the one or more SVs.

An apparatus for collecting floating marine debris comprises a frame, a debris collection container in communication with a rear opening of the frame, a pair of helicoidal screws mounted to the frame in a symmetrical V-arrangement that tapers inwardly from a front opening of the frame to the rear opening, and at least one prime mover rotationally coupled to the pair of helicoidal screws. The prime mover is operable to rotate the helicoidal screws in opposite directions at the same angular velocity in water to move the apparatus forward through the water, such that floating marine debris enters the apparatus through the front opening, passes through the rear opening and is collected in the debris collection container.

An oil containment system aboard a vessel includes a pneumatic system to provide power to a winch and reel assembly containing boom whereby the pneumatic supply is capable of simultaneously powering the winch-reel assembly for boom deployment through inflatable gas fed to a pneumatic motor while also inflating the boom. The inflation of the boom is accomplished by diverting, all or any portion thereof, the inflatable gas from a pneumatic supply through a hose that runs concurrently on the outside of the boom. The pneumatic supply originates from a single pneumatic system powering both the winch and reel assembly as well as associated brake and feeding inflatable gas pressure to the inflation hose running concurrently with the boom. The system can be utilized to confine a discharge of a floating material such as hydrocarbons floating on the surface from a vessel or structure.

A method for cleaning up oil spills using multi-layered carbon fiber-based absorbents is disclosed. The method for cleaning up oil spills requires an oil-contaminated area including a quantity of oil, a first storage vessel, an oil extraction machine, a heating element, and a multi-layered carbon fiber absorbent. The multi-layered modified carbon fiber absorbent is distributed to the oil-contaminated area, where the multi-layered modified carbon fiber absorbent is configured to extract the quantity of oil from the oil-contaminated area while maintaining hydrophobic. The quantity of oil is extracted and separated from the multi-layered modified carbon fiber absorbent using the oil extraction machine. The extracted quantity of oil is collected into the first storage vessel. The extract quantity of oil is then transferred over to a second storage vessel for later refinement.

A solar boat for easy collection of spilled oil and garbage of the present disclosure includes a cabin unit, a boat body consisting of a pair of ship bottoms having a structure that is symmetrical left and right and spaced apart below the cabin unit, a solar panel unit provided above the cabin unit and configured to convert solar energy into electrical energy, a collection and transfer unit provided between the pair of ship bottoms, driven by the electric energy supplied from the solar panel unit, and configured to collect spilled oil and garbage into the inside of the boat body, a garbage storage unit, and a spilled oil storage unit, wherein the collection and transfer unit comprises a rotating conveyor belt, and an oil adsorption member and a collection member that are attached to and detached from the conveyor belt, and the solar boat for easy collection of spilled oil and garbage of the present disclosure has an effect of having excellent work efficiency by simultaneously including an oil adsorption member and a collection member that are attached to and detached from a conveyor belt and simultaneously proceeding with collection of spilled oil and collection of garbage on the water, and an effect of being able to separate the spilled oil from the oil adsorption member, the collection member, and the garbage and easily move the spilled oil to the spilled oil storage unit by including a steam spray nozzle configured to spray hot steam at the end of the conveyor belt.

An apparatus for collecting floating marine debris comprises a frame, a debris collection container in communication with a rear opening of the frame, a pair of helicoidal screws mounted to the frame in a symmetrical V-arrangement that tapers inwardly from a front opening of the frame to the rear opening, and at least one prime mover rotationally coupled to the pair of helicoidal screws. The prime mover is operable to rotate the helicoidal screws in opposite directions at the same angular velocity in water to move the apparatus forward through the water, such that floating marine debris enters the apparatus through the front opening, passes through the rear opening and is collected in the debris collection container.

A sorbent-based oil skimmer is configured to collect oil from an oil layer and passively deposit the oil in an encasing, where the oil can be continuously or periodically removed. The oil skimmer includes an encasing and a sponge that is partially enclosed within the encasing. The sponge has a top sheet in contact with the oil layer and a shell connected to the top sheet, where the shell extends into the encasing. Oil collected by the top sheet is conveyed through the shell, where it is deposited into the encasing under the force of gravity. In some applications, the sponge is manufactured from a silicone-based polymer that has been impregnated with carbonaceous material. The skimmer may optionally include counterweights, ballast tanks, buoyancy adjustment systems and propulsion modules.
