Subsea pressure reduction system

A subsea system, comprising:

• an operator, comprising:
• an operator housing;
• an operator piston movably disposed within the operator housing between and open position and a closed position, the operator piston being sealingly engaged with an inner surface of the operator housing and an inner volume of the operator housing being divided into a closing chamber and a second chamber by the operator piston;
• and
• a piston rod coupled to the operator piston and extended from the operator housing;
• and
• a deintensifier fluidically coupled to the operator, the deintensifier comprising:
• a deintensifier housing comprising an interior;
• a deintensifier piston movably disposed within the interior of the deintensifier housing, the deintensifier piston comprising a closing surface fluidically coupled to the second chamber of the operator housing and an opening surface fluidically coupled to ambient pressure;
• and
• wherein an area of the closing surface is greater than an area of the opening surface so as to increase the pressure differential between the closing chamber and the second chamber and assist in moving the operator piston to the closed position.
