Method for testing hydraulically-actuated devices for leaks
The patent US12037891B2 outlines a method and system for testing hydraulically-actuated devices, particularly those involving a piston that divides an interior volume into two chambers. The method involves moving the piston between two maximum positions by varying the pressure in either chamber. During this movement, at least one parameter related to the pressure, flow rate, or temperature of the hydraulic fluid is measured over a predetermined time. This data is then compared to expected values to identify potential leaks in the device or associated systems. Additionally, the method includes calculating a probability of failure (PFD) over time, which aids in assessing the reliability of the hydraulically-actuated device.
The system described in the patent comprises a hydraulically-actuated device, a hydraulic pump, and a processor. The processor controls the pump to adjust the pressure in the chambers and collects data from sensors to monitor performance. It is designed to detect discrepancies between measured parameters and expected values, which may indicate leaks. The system can also include a reservoir and a remotely-operated underwater vehicle (ROV) interface, particularly for applications involving blowout preventers (BOPs). The method and system aim to enhance the reliability and safety of hydraulically-actuated devices by providing a structured approach to testing and monitoring their performance under varying pressure conditions.
