A rapid-connect coupler includes: an end fitting for conveying a fluid stream; a probe for conveying the fluid stream; a valve configured to occupy a closed position blocking fluid communication between the probe and the end fitting and an open position enabling fluid communication between the probe and the end fitting; a handle configured to actuate the valve between the closed and open positions; a sleeve moveable between a first sleeve position and a second sleeve position. The sleeve, in the first sleeve position, is configured to prevent the handle from actuating the valve from the closed position to the open position.

In various embodiments, fluid conduits such as high pressure hoses deployed in-between two sea-fairing vessels may be released during an emergency by using a rapid release emergency disconnect system as described herein, where the rapid release emergency disconnect system may engage with a hanger such as an industry standard frac hanger and be used in-line with fluid conduits such as high-pressure lines. Various skid embodiments are described which can be configured to interface with one or more of the described rapid release emergency disconnect systems.

A disconnect fitting adapted for use with a phase changing composition including a fitting base having a first fitting base end, a second fitting base end and a fitting base opening therebetween, a pin capture disposed within the fitting base opening, a displaceable pin secured within the pin capture, a fitting socket having a first fitting socket end, a second fitting socket end, a fitting socket opening therebetween, the second fitting socket end secured to the second fitting base end, and a valve at least partially disposed within the fitting socket opening. When the displaceable pin is in an unloaded condition, the displaceable pin extends in a direction of the second fitting base end, and when the displaceable pin is in a loaded condition, the displaceable pin is compressed in a direction of the first fitting base end. The pin capture permits passage of the phase changing composition through the fitting base opening when the displaceable pin is in the unloaded condition or the loaded condition. The disconnect fitting permits a secure connection of the fitting base and the fitting socket regardless of the state the material when the base and socket are disconnected.

A coupling unit for a fluid element includes a monolithic body having a head and a threaded portion extending from the head, the threaded portion including a core and a thread formed on the core. The monolithic body defines a first bore and a second bore that extend through the monolithic body substantially parallel to each other, the first and second bores each having a circular cross-section.
