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.
