A submersible sieve apparatus provided with an exoskeletal frame enveloping a filter element and a detached post-filter backing; positioned to strain a lotic stream of entrained sediment prior to or upon being deposited. The frame can positioned and manipulated for greater efficiency. The filter and backing will take the shape of the frame and the backing may or may not be attached.

The present invention generally relates to containment and control of an oil spill caused by a damaged or broken riser in deepwater. More specifically, the present invention relates to a reusable unit that will contain oil spills to a specific location and will also allow oil to be harvested as it flows to the top of the unit while minimizing or even eliminating any environmental clean-up cost. The unit of the present invention is dropped over a damaged or broken riser in a closed position, the unit is released and stabilized in sections until the surface is reached and the containment unit is completely erected.

A resiliently deformable containment structure having an open bottom end and a raised center portion. A central hub, situated centrally in a textile containment sheet, is provided. A plurality of elongate inflatable beam members are arranged circumferentially around the central hub, each extending radially outwardly and in a downwardly-extending manner therefrom and each underlying or overlying the textile containment sheet to support, when inflated, the textile containment sheet in a downwardly-extending shape to form an enclosure having an open bottom end. Distal ends of the inflatable beam members are tethered to one or more anchor members situated below the open bottom end of the dome structure. The structure is suited for placement above and over a compromised sub-sea structure for collecting and recovering to surface fluids which may be leaking therefrom. A method for containing and recovering such fluids from a compromised sub-sea structure is further disclosed.

An oil-collecting apparatus includes: a body including an inlet through which a liquid is introduced, a first outlet through which purified water generated from the liquid introduced through the inlet is discharged, and a second outlet through which materials collected from the liquid are discharged; and a filter arranged at the first outlet of the body and generating the purified water by collecting the materials included in the liquid by allowing the liquid introduced through the inlet to pass therethrough.

The present disclosure relates to a fence having a hydrophilic material, and according to an embodiment of the present disclosure, there is an effect in collecting oil or hazardous & noxious substances quickly and efficiently while minimizing the pressure caused by water, by forming the fence from a material that allows water to penetrate while disallowing oil to penetrate.

Additionally, there is an effect in preventing oil spill phenomena caused by damage or unbalance of the fence by reducing the water pressure applied to the fence due to water penetration even when a strong water pressure acts on the fence, for example, strong tidal currents occur and the fence is towed at high speeds to collect oil.

A floating-oil recovery device includes: a bubble-curtain generation mechanism configured to discharge air into water to generate a bubble curtain in the water so as to increase a thickness of a film of floating oil while regulating spread of the floating oil; and an ejector configured to recover an oil-water mixed fluid having the floating oil and the water mixed with each other by jetting high-velocity water toward the film of floating oil enclosed with the bubble curtain to destroy the film of floating oil.

A floatable, portable and readily deployable apparatus used in a surface water body for the collection, mixing, separation, containment and removal of total solids from fluid in surface water by settling, sorption, floatation or filtration of total solids from fluid entering or induced to flow into the apparatus. Separation of total solids from fluid can include the use and recycling of commercially available or proprietary biologic, chemical and/or physical substances and processes to increase the rate and percentage of total solids removed from fluid in the apparatus.

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.
