A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline includes an upstream portion of the pipeline supplying a flow of fluid material, a crossing portion of the pipeline receiving the flow of fluid material from the upstream portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline, the downstream portion, a pipeline pressure activated valve selectively capable of blocking the flow of fluid material from entering the crossing portion based upon a change in pressure within the crossing portion, and a fluid capacitor connected to the upstream portion configured to filter out a pressure spike in the upstream portion associated with the valve blocking the flow of fluid material.

Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

A mobile fuel monitoring system (MMU) is disclosed. The fuel monitoring system may be skid mounted and is configured to monitor fuel transfers between a fuel source and a vessel, such as a ship. The disclosed MMU is a stand-alone, self-contained unit that can be easily moved from place to place. The MMU is configured to monitor and remotely report custody transfers of fuel performed at any location. Parameters of the fuel transfer operation, such as the amount of fuel transferred, the flow rate, the fuel density, and fuel temperature can be monitored and alarms may be issued if any of the parameters are out of specification. The parameter values may be transmitted to a remote location, for example, via a satellite link.

A fluid delivery system includes a distribution station moveable between a first location and a second location, a pump on the distribution station, at least one manifold on the distribution station and fluidly connected with the pump, a plurality of hoses connected with the at least one manifold, each of the hoses including a tube and a protective sleeve that circumscribes the tube, a plurality of valves on the distribution station, each of the valves situated between the at least one manifold and a respective different one of the hoses, a plurality of fluid level sensors, each of the fluid level sensors being associated a respective different one of the hoses, and a plurality of sensor communication lines. Each of the sensor communication lines is connected or connectable with a respective different one of the fluid level sensors. Each of the sensor communication lines is routed with a respective different one of the hoses. Each of the sensor communication lines is secured to the tube of one of the hoses by the protective sleeve.

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.

The safety joint 100 according to the present invention includes a plug (10: vehicle side member) with a cylindrical shape in which a passage (1A: in-plug passage) is formed, a socket (20) in which a passage (21A: in-socket passage) continuing to the passage (1A) in the plug (10) is formed, and a shut off valve mounted on the passage (21A: in-socket passage) in the socket (20), the shut off valve opening when the plug (10) being inserted into the socket (20) and closing when the plug (10) being disconnected therefrom, wherein central axes of the passages of the plug and the socket do not form a straight line (but those are orthogonal with each other for instance), a filling hose (61) is connected to the plug (10), and a hose guide (70, 70A) for limiting movement of the filling hose (61) at a position separated from the plug (10).

A coupling for transferring fluids is provided, having a housing and a nipple which can be fastened thereto and separated from the housing when a predetermined axial pulling force is exceeded, while overcoming a spring force, and having a fluid duct traversing the housing and the nipple, a housing-side and a nipple-side non-return valve and is routed in a radially guided manner around a vented cylindrical interior of the nipple. A closure mechanism comprises respective valve-side pins and a sleeve arranged between these pins, the sleeve being axially movable in the interior of the nipple and lockable to at least one of the pins by means of spring pressure-mounted locking elements so that, with the nipple fixed, the non-return valves are held open against their spring force, and, with the nipple released, the housing-side non-return valve is completely closed and the nipple-side non-return valve is at least partially closed.
