A system of multiple non-manifolded fuel tanks on a portable platform and preferred embodiments which allow for improved access to the contents of each fuel tank, ability to transport multiple fuel types in a single system on a vehicle without towing apparatus, and the ability to maneuver the system via a forklift.

A system and method for fueling multiple saddle tanks of hydraulic fracturing equipment from a single cart. The cart having multiple retractable fuel lines for providing and obtaining fuel. Each retractable fuel supply line uses a flowmeter, a ball valve, and an electrically actuated valve to provide remote control to a controller based upon a user's selected fueling requirements. An electronic reporting system provides fuel data to operators and users. Fuel data such as fuel tank status, amount of fuel usage over a stage level, a daily level, or job level along with a fill level of the fuel tank.

A distribution station includes a mobile trailer, a pump on the mobile trailer, a manifold on the mobile trailer and connected with the pump, a plurality of hoses in communication with the manifold, and a plurality of valves on the mobile trailer. Each of the valves is situated between the manifold and a respective different one of the hoses. Each of a plurality of fluid level sensors is associated with a respective different one of the hoses. The fluid level sensors are operable to detect respective different fluid levels. A controller is configured to operate the valves responsive to signals from the fluid level sensors, activate and deactivate the pump, identify whether there is a risk condition based upon at least one variable operating parameter, and deactivate the pump responsive to the risk condition.

Fuel delivery vessels and vehicles are described. Some embodiments include nozzles for access by an operator. Some embodiments include optimized size and material characteristics. Some embodiments include various dispensing systems.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

A fluid dispensing system. The fluid dispensing system includes a portable source container, a fluid dispensing nozzle, a pump system, a fluid conduit, and a power connector. The pump system includes at least one pumping portion for pumping fluid through a first fluid passage, an electric motor for powering the first pumping portion and a power receptacle for receiving power to the electric motor. The pump system is coupled the source container or the fluid dispensing nozzle. The power connector includes at least one retaining clip biased to a retaining configuration, the first retaining clip in the retaining configuration being configured to enable the power connector to be retained in the power receptacle.

Devices, systems and methods of transferring liquids or mixtures/slurries of liquids and solids between vessels having challenging and difficult configurations and locations, and over long and short distances in a continuous or near continuous discharge for storage or transport using a combination of vacuum and pressurized fluids.

A refuelling stand that is lightweight and easily portable which includes A refuelling stand for conveying fuel from a fuel source into a fuel receptacle comprising: a funnel which is optionally collapsible; a conduit having a first end for removable attachment to the funnel, and a second end for engagement with the fuel receptacle; and three or more support legs, wherein each of the support legs is independently movable from a first use mode to a second storage mode. The conduit can be made of flexible material which may be rolled up for storage alongside the support or may be formed of inflexible tubing. The refuelling stand may optionally include at least one stabilizing element.

An unmanned self-sustained fuel dispensing station for fuels of all sorts (gasoline, pesticides, water, fertilizers etc.) a tank, docking, and coupling system for unmanned aerial vehicles (UAV) of the vertical takeoff types. The station can be independent of public power and communication utilities and can operate by remote control without an on-site attendant. The preferred system has a central command center with a control computer in communication with a station control computer located at one or more satellite stations through a communications link. The station control computer can be controlled remotely by the command center. The station control computer programming has control over the activities of the station through an electrical generation subsystem with a solar array, battery bank, battery charger and standby generator; a fuel dispensing subsystem; a security subsystem with video cameras; a communications link and a status sensor subsystem.

A mobile fuel distribution station includes a mobile trailer, a pump, a manifold, hoses, detachably connectable fuel caps connected or connectable with the hoses, valves, and fuel level sensors. The station is configured to operate the pump responsive to a low fuel threshold to provide fuel to the manifold, from the manifold to the valves, and from the valves through the hoses. A related method includes receiving fuel operating parameter data from at least one mobile fuel distribution station into a remote server, determining whether the fuel operating parameter data is within a preset limit, and sending a control action in response to the fuel operating parameter data being outside the preset limit. A related system includes one or more of the stations, at least one server configured to receive fuel operating parameter data, and at least one electronic device configured to communicate with the server.
