An example work machine control system includes target fill level determination logic configured to determine a target fill level for a container of an earth-moving work machine, fill level measurement logic configured to receive a sensor signal from a sensor that detects contents of the container and generate a measurement metric indicative of a current fill level of the container based on the sensor signal, and control logic configured to generate a machine control signal based on the measurement metric and the target fill level.

A method and apparatus for digging and removing excavated material provides a mobile device, having a movable or self-propelled chassis, and an elongated, preferably articulated boom with a free end portion having an excavating implement (e.g., digging, excavating or jetting tool). The boom has at least three sections that are foldable to a storage position on the chassis wherein one boom section stacks upon or is aligned with another boom section. The vacuum line is supported upon the boom, extending along the boom and above the earth's surface, wherein the vacuum line extends between the free end portion of the boom and the chassis. The boom attaches to the chassis at a base. The excavated material is vacuumed with the vacuum line into a collection vessel or tank that can be a part of a wheeled vehicle. A separate vacuum truck can provide a vacuum to a selected collection tank.

An overflow system for a hopper dredger comprises an overflow tube; an inlet for taking in head water from the hopper; and a collector to collect the flow of head water entering the inlet and guide the flow to the overflow tube. The collector comprises a substantially horizontal top portion which delineates a top of a flowpath for head water into the collector to ensure substantially radial flow into the collector. At least one of the overflow tube and the inlet is adjustable for controlling flow into the overflow system.

An ocean-going single-hulled barge with an isolated sunken or recessed area that supports storage vessels and mixing equipment capable of processing, storing and transporting hazardous materials. The recessed area includes dedicated drains which collect all associated hazardous spills and fluids for appropriate disposal and processing. The barge can also be adapted to hold a complete liquid mud plant within the recessed area.

A system and method for various levels of automation of a swing-to-hopper motion for a rope shovel. An operator controls a rope shovel during a dig operation to load a dipper with materials. A controller receives position data, either via operator input or sensor data, for the dipper and a hopper where the materials are to be dumped. The controller then calculates an ideal path for the dipper to travel to be positioned above the hopper to dump the contents of the dipper. In some embodiments, the controller outputs operator feedback to assist the operator in traveling along the ideal path to the hopper. In some embodiments, the controller restricts the dipper motion such that the operator is not able to deviate beyond certain limits of the ideal path. In some embodiments, the controller automatically controls the movement of the dipper to reach the hopper.
