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.

A barrage with a function of collecting floating garbage on a water surface is provided. It includes a first dam body as a main body of the barrage provided with multiple built-in low water level drainage channels and high water level drainage channels, a second dam body provided with multiple notches for converging floating garbage on the water surface, a garbage collecting and storing equipment arranged between the first dam body and the second dam body and a solar power generating equipment. The garbage collecting and storing equipment maintains running of the garbage conveyor belt by utilizing electric energy provided by the solar power generating equipment, thereby collecting garbage in a garbage pool beside the barrage. It not only has conventional functions of the barrage, but also greatly saves cost of manually salvaging garbage and avoids water pollution caused by accumulation of garbage on the river surface.

A novel water-borne debris collection system integrated into a waterborne vessel for collecting surface and near surface debris in a body of water, such as a river, lake, or ocean. The apparatus may include a solid collection boom that projects laterally from a vessel and is partially submerged to act as a collection mechanism. The boom also facilitates the propulsion of the vessel by providing a barrier across which a differential water surface level may be created to drive the vessel forward. The apparatus may include a pumping system that draws water from the anterior side of the screen and for multiple purposes, including processing the collected water to remove plastics and other pollutant and debris material therefrom, and to transfer the water to the posterior side of the screen to create the differential water level for driving the vessel forward.

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.

Provided is a toothed drum type oil recovery device, which includes: a recovery drum having a center coupled to a rotary shaft and having a plurality of tooth units formed around an outer circumference thereof, wherein one side of the recovery drum is disposed in the water to which oil is spilled so that the oil is recovered by the tooth unit at one side of the recovery drum according to the rotation; and a separation unit containing an oil separating liquid and disposed at the other side of the recovery drum, wherein when the tooth unit moves onto the oil separating liquid at the other side of the recovery drum according to the rotation of the recovery drum, the oil separating liquid is introduced into a space between the tooth units adjacent to each other by means of a capillary action to separate the oil from the tooth unit.

Garbage collection apparatus for the collection of plastic from a surface of a waterbody with a waterflow. The garbage collection apparatus comprises a base and a horizontal beam mounted pivotably around a vertical axis on the base. Said horizontal beam is mounted displaceably in vertical direction on the base, where said horizontal beam on an underside comprises a collection device for collecting plastic floating on the surface of the waterbody. The collection device extends vertically away from the horizontal beam and extends horizontally in a direction opposite the direction of the water flow in the waterbody, which collection device comprises one of either bars or mesh, where said garbage collection apparatus comprises a first actuator for displacing the horizontal beam in or into vertical direction and where said collection device is connected rotatably to the horizontal beam and where the rotation axis of the collection device relative to the beam is parallel to a main axis of the horizontal beam and where the garbage collection apparatus comprises a controller. Method for removing plastic from the surface of a waterbody with a water flow, with a garbage collection apparatus.
