    Abstract: An accumulator system includes a chamber configured to receive a first fluid, a piston configured to move within the chamber to pressurize and drive the first fluid out of the chamber, a driving shaft coupled to the piston, a screw adapter coupled to the driving shaft, a plurality of anti-rotation shafts, and an electric actuator configured to couple to the screw adapter and to rotate the screw adapter to axially move the driving shaft. The piston includes a body defining a first aperture and a plurality of counterbores. The driving shaft is coupled to the piston via the first aperture. The piston is configured to slide over the plurality of anti-rotation shafts via the plurality of counterbores.

    Abstract: A computer-aided engineering (CAE) toolkit is disclosed that streamlines and automates aspects of a CAE simulation to validate the designs of pressure-controlling components, such as BOP rams. The CAE toolkit enables a designer to provide a model of a pressure-controlling component, and to provide property values that describe aspects of the system to be modeled. Based on these inputs, the CAE toolkit generates a model for the system that includes the pressure-controlling component, as well as any other components that will be part of the simulation. The CAE toolkit can automatically generate a finite element analysis (FEA) model from the system model, and then use the FEA model to perform a simulation of the pressure-controlling component during operation. The CAE toolkit enables a designer with no training or experience with CAE or FEA techniques to perform and automate simulations of the operation of a pressure-controlling component design.
