Abstract

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.

Claims30

Dependent claims

A skid, comprising:

a. a directional control valve, the motor quick release comprising a fluid input;
b. a first valve in fluid communication with the fluid input;
c. a hydraulic motor in fluid communication with the fluid valve, the motor further comprising a fluid feedback;
d. a fluid reservoir in fluid communication with the hydraulic motor;
e. a quick connect disposed intermediate and in fluid communication with the hydraulic motor and the fluid reservoir;
f. a hydraulic power unit (HPU) in fluid communication with the fluid reservoir, the HPU comprising an adjustable pressure relief valve;
g. a three stage intensifier in fluid communication with the HPU;
h. a second valve in fluid communication with the three stage intensifier, the second valve comprising a lock-out;
i. a pressure regulator valve in fluid communication with the second valve;
j. an electrically actuated valve in fluid communication with the pressure regulator valve and the hydraulic motor;
k. a third valve in fluid communication with the second valve, the third valve comprising a lock-out;
l. a hydraulic accumulator in fluid communication with the third valve;
and
m. a second fluid tank in fluid communication with the hydraulic accumulator, the second fluid tank further comprising:
i. a dry gauge in fluid communication with the hydraulic accumulator;
ii. a fluid tank;
iii. a fourth valve disposed intermediate and in fluid communication with the hydraulic accumulator and the fluid tank, the fourth valve comprising a lock-out and configured as a fluid isolation valve with respect to the fluid tank;
iv. a pressure relief valve;
v. a fifth valve disposed intermediate and in fluid communication with the fluid tank and the pressure relief valve, the fifth valve comprising a lock-out and configured as a fluid isolation valve with respect to the fluid tank;
and
vi. a pressure vent in fluid communication with the pressure relief valve.
