  • Hydrostatic Pressure Test Method and Apparatus
    Publication number: 20200370987
    Abstract: A method of pressure testing a closed hydraulic system for leaks includes heating or cooling pressure intensification fluid before it enters the closed hydraulic system under pressure. The closed hydraulic system may be for example a blowout preventer for an oil/gas well, a manifold system or tubulars. The intensification fluid is heated or cooled to a temperature at or near the temperature of the fluid within the closed hydraulic system.
    Type: Application
    Filed: August 11, 2020
    Publication date: November 26, 2020

  • Variable ratio rotary energy control device for a blowout preventer safety device
    Patent number: 10190381
    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.
