An extraction vessel is provided that includes two pontoons forming parallel hulls, a cargo hold located between the pontoons, and a retractable extraction conveyor belt located between the pontoons and mounted on tracks so as to be movable between retracted and deployed positions. In the retracted position, a lower end of the conveyor belt is above the waterline of the vessel. In the deployed position, the lower end of the conveyor belt is below the waterline for extracting the floating debris, and an upper end of the conveyer belt is above the cargo hold to discharge the floating debris into the cargo hold. Also provided is an extraction vessel that includes variable buoyancy floats attached to the pontoons and movable between a raised position in which the lowest surface of the float is above the waterline, and a lowered position in which part of the float is submerged.

A recovery system for large-scale spilled oil flowing onto and adhered to a shore is disclosed. The recovery system for large-scale oil flowing onto and adhered to a shore is mounted on an amphibious vehicle that can move on a neritic zone and land. A skimmer assembly is installed in a front of the amphibious vehicle. An oil collection assembly is foldably provided on each of front opposite sides of the amphibious vehicle, thereby easily collecting oil. A recovered oil treatment assembly is mounted on the amphibious vehicle and configured to accommodate the oil recovered by the skimmer assembly therein and to store separated oil by separating water from the accommodated oil.

A robotic system having a movable gantry robot (10) for conducting construction operations. The gantry may have an expandable bridge (20) and articulated gantry support legs (34) as well as a support track system (60) holding a gantry robot (800) which may hold one or more implements and peripheral devices (806). The device can be moved by propulsion mechanisms, a controller, and one or more geo-positioned control devices to provide position information for the robotic gantry as it moves back and forth along a plurality of work sites (700). The robotic gantry is connected to a power supply system (236). The controller is automated, self-navigating, and activates, deactivates, and/or changes the operation of the propulsion mechanisms, and deploys, retracts, activates, deactivates, and/or changes the operation of one or more of the construction implements. The height of the frame may be adjusted by extending and rotating risers and booms to accommodate different building heights or sub-level heights at a worksite. A conveyor system is optimized for removing dirt from or delivering material to the robotic arm. This invention can be applied to automating construction jobs including surveying, land preparation, excavation, foundation, masonry, framing, and additive fabrication.

The present disclosure relates to a service station that is transportable over a predetermined roadway or by water. The service station has a base having a stern, bow, and two lateral sides. The base is configured to displace a volume of water so as to render the service station buoyant. A tank is disposed on the base and is configured to contain fuel. The tank is configured to comply with U.S. Government requirements for transportation of fuel over roadways. A pump is disposed on the base, and is configured to dispense liquid fuel to supply vehicles. An axle assembly is coupled to the base and has at least one wheel, the at least one wheel and axle assembly moveable between an engaged position and a stored position. The least one wheel is in contact with a surface and partially supports the base over the surface in an engaged position.

An amphibious pumping vehicle has a floatable vehicle body, a ground engaging propulsion structure, a fluid pump, a plurality of fluid nozzles comprising a first fluid nozzle connected by a fluid conduit to the fluid pump and at least one second fluid nozzle connected to the fluid conduit, a valve structure in the fluid conduit, the plurality of fluid nozzles and the valve structure co-operating to provide directional control and motive power for the vehicle when floating, and a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump.

A shock absorbing system of an amphibious and remotely controlled vehicle is provided, including a chassis, a controller, a transmission shaft, six transmission members, a front wheel driving mechanism, a rear wheel driving mechanism and a smart electronic device. When the smart electronic device transmits a first control message, the controller drives the transmission shaft to pivot toward a first direction, the transmission shaft leads the six transmission members to pivot and the controller and the chassis move away from the casing of the remotely controlled vehicle. When the smart electronic device transmits a second control message, the controller drives the transmission shaft to pivot toward a second direction, the transmission shaft leads the six transmission members to pivot and the controller and the chassis move toward the casing of the remotely controlled vehicle.

An amphibious transport apparatus includes forward and aft ends, a pair of spaced apart pontoons including tracks, and a transversely extending structure, which can include a platform, that spans between the pontoons and connects the pontoons together. The amphibious transport apparatus further includes a sled vessel that can be used to transport materials or personnel. The sled can be releasably attached to the amphibious transport apparatus with tow bar and a pivotal connection. Said tow bar can be rotatable between an upper storage position wherein the tow bar engages the vessel away from said pivotal connection and above a terrain surface, and a lower towing position. A towing position of said amphibious craft and sled can be defined by the sled connected to the amphibious craft at the releasable pivotal connection, with the amphibious craft being self propelled with said tracks for engaging the underlying terrain and with the sled in the lower towing position so that the sled bottom drags along on the underlying terrain during movement of the amphibious transport apparatus and sled. A trailer for loading and unloading the sled can also be provided. The amphibious craft can push the sled onto the trailer during loading.
