摘要： The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.

摘要： A subsea trencher for arranging at least partly into the seabed a subsea pipeline, includes
at least one cart that separately carries at least one trench tool and is configured to run along the subsea pipeline. trench tool is configured to work the seabed underneath the subsea pipeline.
A subsea support frame carries heavy subsea equipment connected to the trench tool for operating the trench too.
When the subsea support frame is fixed to the cart, the subsea trencher is configured to load the assembled weight of the cart and subsea support frame onto the subsea pipeline as the subsea trencher runs on the subsea pipeline.
When the subsea support frame is separate from the cart, the subsea support frame is configured to be suspended above the seabed or arranged beside the subsea pipeline at a distance from the subsea pipeline as the cart runs along the subsea pipeline.-

摘要： Composite particles contain a natural stone or aggregate core and a coating of two or more sorbent layers collectively containing at least two distinct kinds of sorbent materials effective for sorbing two distinct contaminants. One or both sorbent layers may be mixed with a water-absorbent, swellable clay that, upon contact with water, causes spalling or disintegration of the coating layer to release the sorptive material into a body of water such as a pond, ditch, stream, or riverbed. Additional swellable or protective layers may also be present. The composite particles are deployed into a pond, ditch, river, or streambed where the core of natural stone remains in the riverbed. The sorptive materials of the two different sorbent layers sorb and fix a wide range of contaminants, including both the heavy and light-weight hydrocarbons, from the water, and settle as a fine sediment. The sediment with sorbed contaminants is then removed by means such as hydraulic collectors or dredging.

摘要： An annulus excavation tool that would surround the decayed pole or pile and hydraulically excavate the annulus around the pole down to −2.0′ via a jetting manifold. A vacuum/tremie manifold is selectively coupled to a vacuum source to remove the soil and decayed material and creating a bonding surface for the mortar. The annulus tool would then be coupled to the mortar source and raised while a UHPC mortar would be tremied into the tool for delivery into the annulus. When the tool reaches ground level the rest of the pour is done using a Sonotube or other temporary form. This mortar encasement not only makes up for the structural deficiencies but also isolates the pole from both air and water which then kills the existing fungi and insects while also preventing any future invasion.

摘要： A cutter head arranged to rotate about an axis of rotation for removing material from a water bed comprises a base ring positioned respect to the axis of rotation; a hub positioned with respect to the axis of rotation; a plurality of arms extending between the base ring and the hub, the arms comprising a plurality of cutting tools; and a plurality of skirts, each skirt extending from one of the plurality of arms to the hub to form a closed surface between the arm and the hub from a distal end of the cutter head toward the base ring and ending with a side configured to be parallel to a backplate, leaving an open channel between the skirt and the backplate.

摘要： In order to meet the objective of providing a device (10) and a method for a sediment transfer in waters (80, 81, 90) that works efficiently, a device (10) comprising at least one suction line (12) and at least one receiving means (16) for receiving sediment (70), and furthermore, having at least one pressure line (14) for transferring the received sediment (70) is proposed. Following the at least one receiving means (16), at least one pump device (18) and at least one measuring device (20) for determining a sediment concentration of the received sediment (70) are arranged. The device (10) further comprises a control unit (22) having a first interface (25) for inputting target values (24) and a second interface (26) for the at least one measuring device (20), and determines a sediment concentration in the at least one suction line (12) and/or in the at least one pressure line (14). Depending on the sediment concentration, a power of the pumping device (18) is adjustable.

摘要： A system for dredging a seabed includes a trailing suction hopper dredger. The trailing suction hopper dredger includes a hull, a rail coupled to the hull, and a dredge arm coupled to the rail. The dredge arm includes an upper suction pipe coupled to a lower suction pipe. A pump is coupled to the upper suction pipe and is configured to draw material toward the upper suction pipe from the seabed. A visual marine life deterrent is coupled to the dredge arm and is configured to direct light toward the sea floor where marine life may be located. Another visual marine life deterrent includes a silhouette of a marine life predator. The visual marine life deterrents are configured to be observable by the marine life and cause marine life to move away from the dredge arm.

摘要： A collection tank for use in a vacuum operated earth reduction system, the collection tank comprising a closed first end, an open second end defining a tank sealing flange and a body extending between the closed first end and the open second end. An internal chamber defined by the body, the closed first end and the open second end has a door coupled to the open second end and is configured to releasably seal the open second end. An automated door closer is coupled to a center of the door, wherein the automated door closer provides a closing force at the center of the door so that the closing force is equally distributed about a periphery of the door to seal the door against the tank sealing flange.
