The present invention provides a system, apparatus, and method for harvesting objects from the bottom of aquatic environments. The invention preferably provides a system, apparatus, and method for utilizing swarms of autonomous harvesting vehicles to harvest polymetallic nodules from the ocean floor.

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.

A treatment method for a river system in a reservoir area, comprising: S1. determining whether a time from a current date to the rainy season is less than a preset duration; S2. moving a pressure sensor upward; S3. determining whether the pressure data meets corresponding conditions; S4. determining whether a duration of the pressure data is less than the preset duration; S5. determining whether an interval between the current time and the time for collecting pressure/nitrogen and phosphorus is greater than a preset number of days; S6. acquiring an image information of a river bottom, and sending it to neural network model for identification to obtain a depth of a sludge; S7. determining whether the depth of a sludge has reached a dredging depth, if so, starting a sludge pump to clean up; S8. collecting nitrogen and phosphorus concentration, and removing nitrogen and phosphorus when the concentration exceeds a standard.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

A work machine includes a frame, a linkage assembly, a work implement connected to the linkage assembly, and a grade control calibration system. The grade control calibration system includes a vision processing system, which includes a sensor fixed to the linkage assembly and a first controller. The vision processing system is configured to measure a length of a cutting portion of the work implement, and to transmit the length of the cutting portion of the work implement. The grade control calibration system also includes a grade control system in communication with the vision processing system and the linkage assembly. The grade control system includes a second controller configured to receive the length of the cutting portion of the work implement from the first controller, and to calibrate a position of the work implement based on the received length of the cutting portion of the work implement.

A shovel includes an attachment attached to an upper turning body and a processor configured to calculate a weight of a load carried in the attachment in accordance with a mode selected from a plurality of modes with respect to timing of detection.

Systems and methods include a wing tool configured to be operable from work vessel(s), the wing tool including thrusters capable of fluidizing sediments from a first seabed location and moving it to a second seabed location, the second seabed location including a trench or differently shaped collection sump previously made by the wing tool and/or an extraction pump. The extraction pump operates from a second work vessel having sufficient capacity to pump fluidized sediments from the trench. Certain systems include a separation unit that separates sand from silts and clays and water from collected sediment. Systems and methods for reclamation of reservoirs, moving sand waves, for pre-trenching and/or recovering marine pipelines and cables, for removing cover from marine archaeological sites and for disposing of contaminated bottom materials in an environmentally acceptable manner.

A damage estimation device includes: an operation parameter reception unit that acquires an operation parameter related to an operation of a work machine; a damage estimation model storage unit that stores a damage estimation model constructed by machine learning using training data with the operation parameter as an input value and a damage parameter related to damage in a predetermined portion of the work machine as an output value; and a damage parameter estimation unit that estimates the damage parameter by inputting the operation parameter acquired by the operation parameter reception unit to the damage estimation model stored in the damage estimation model storage unit.

A method for converting material within a vacuum tank that contains a mixture of liquid and solid material into a solidified batch of material. The method utilizes various devices to measure different features and properties of the tank and its contents to determine an amount of drying agent to be added to the tank. The method further utilizes various devices and methods for adding the drying agent to the tank and mixing the drying agent with the material within the tank. The method described herein may be completed automatically in response to human input on a handheld display device.
