Claim 12:
13. The method of claim 12, further comprising:
forcing hydraulic fluid from the closing side of the double acting piston cylinder into an accumulator of the system, in response to pumping hydraulic fluid from the fluid reservoir to the opening side of the double acting piston cylinder;
increasing pressure of the hydraulic fluid within the accumulator, in response to forcing hydraulic fluid from the closing side of the double acting piston cylinder into the accumulator; and
clamping the first flange and the second flange together again, in response to a controller of the system operating the control valve to move the control valve to a neutral position, in which the fluid reservoir is in fluid communication with the opening side of the double acting piston cylinder, wherein hydraulic fluid is forced from the accumulator into the closing side of the double acting piston cylinder, in response to releasing pressure in the accumulator in response to allowing hydraulic fluid to move from the opening side of the double acting piston into the fluid reservoir, in response to the controller operating the control valve to move the control valve to the neutral position while the closing side shut-off valve is maintained in the closed position, wherein the controller operates the control valve in response to receiving a signal from at least one sensor sensing a condition of the bolt flange joint.
