An igniter 40 activated blocking device 10 blocks a fluid line 4 adapted to carry fluid. The blocking device 10 has a housing 30 disposed about the fluid line, a piston 20 housed in the housing, and an igniter 40 that when activated propels the piston 20 to block the fluid line 4. The igniter 40 generates a shock wave to move the piston 20 to block the line. The piston 20 crushes or squeezes a portion of the line 4 to close the line.

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 dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

A pipe (14) extending between a surface end (20) and a bottom end (22) thereof, and defining an internal passage (24) ending at the bottom end (22) and at the surface end (20). A dynamic closing member (30) at the bottom end (22), which opens above a threshold pressure applied from the exterior towards the interior of the pipe (14), and closing below the threshold pressure. The threshold pressure is defined as a function of at least one parameter representing the heaving of the pipe under the effect of variation in height of the water in which the pipe extends.

High-pressure cryogenic fluid conduits that deliver high-pressure cryogenic fluids from a first point to a second point. This high-pressure fluid conduit has a safety feature that is activated when the high-pressure cryogenic fluid conduit fails due to exposure to a predetermined force. The safety feature is activated by the fracture of an annular ring that is positioned at either end of the high-pressure fluid conduit and is calibrated to fracture when exposed to the predetermined force. Fracture of the annular ring closes valves at each end of the high-pressure fluid conduit, thereby stopping the flow of high-pressure fluid from the high-pressure fluid source as well as the escape of high-pressure fluid from the high-pressure fluid container.

An apparatus includes a handheld element and a remote control. The handheld element has a proximal end, a distal end, and an internal flow conduit. The internal flow conduit extends between the proximal and distal ends. The internal flow conduit is configured to be in fluid communication with a hose. The remote control is integrated with the handheld element. The remote control is configured to transmit wireless data signals for controlling a device associated with the hose. The device may include a reel, a valve system, a valve unit, and/or a plurality of valves.

A retractable fitting with a stopcock has a stopcock housing for connection to a pipe or process chamber. The housing has a connection opening into the pipe or process chamber. A shut-off body is rotatable about a pivot axis relative to the stopcock housing, and has a passage hole that merges in an open state of the stopcock into the connection opening of the stopcock housing, the connection opening being closed by the shut-off body in a closed state. A support element in the passage hole is introduced in the open state through the connection opening into the pipe or process chamber. A plurality of flushing lines are operable to conduct a flushing medium, the plurality of flushing lines being accessible from outside of the stopcock and being connected to and/or opening into the passage hole of the shut-off body at least in the closed state of the stopcock.

The disclosure presents systems and methods for hot swapping pumps at a wellsite while minimizing the impact to the pumping operations. As one pump is swapped out, such as for maintenance, the remaining pumps in the set of pumps at the wellsite can continue pumping operations. In some aspects, the swapping of pumps can be performed by a user using a protection barrier to isolate the pump location where the pumps will be swapped. In some aspects, one or more of the steps to swap pumps can be performed through automation thereby minimizing danger to a user. In some aspects, the pump being located at the pump system can be primed and pressure tested prior to be located to improve the time to enable the pump for pumping operations.

An electrovalve for monitor and controlling the fluid supply of an installation of a building, said installation comprising piping in which a fluid circulates, said electrovalve comprising an electrovalve body (2), an inlet (23) to be connected to said piping (10), an outlet (24) also to be connected to said piping (10), a passage (25) provided between said inlet (24) [sic] and said outlet (25) [sic], equipped with sealable closing means (31) movable between an open position, by which the fluid is allowed to circulate in said passage (25) between said inlet (23) and said outlet (24), and a closed position by which the passage (25) is blocked and prohibits any circulation of fluid between said inlet (23) and said outlet (24). The electrovalve comprises a device (4) for controlling the closing means (31) associated with a flowmeter (5). According to the invention, the flowmeter (5) comprises an internal chamber (50) provided in the body of the electrovalve and the electrovalve comprises a secondary fluid passage circuit between the inlet of the chamber and the outlet of the chamber, the inlet and the outlet being connected to the primary fluid passage circuit.
