Abstract
A method and apparatus for activating a safety device of a blowout preventer utilizes a variable ratio rotary energy controller. The controller automatically adjusts the pressure of the fluid for activating the safety device thereby conserving the amount of energy required for each activating cycle. The controller includes a variable displacement hydraulic motor coupled to a variable displacement hydraulic pump. A system for recharging the activating fluid circuit allows for the actuating system to be reused as needed.
