    Abstract: A plurality of PODs for a lower marine riser package (LMRP) is disclosed. At least a first subsea electronics module (SEM) and a second SEM are provided in a first POD of the plurality of PODs. At least a third SEM and a fourth SEM are provided in a second pod. The third SEM is redundant with the first SEM and the fourth SEM is redundant with the second SEM. At least one selector circuit is provided to transmit an SEM select signal that electrically activates or electrically deactivates the first SEM separately from the third SEM. As a result, each of the SEMs in the plurality of PODs may be separately activated or deactivated without a need to turn off fluid provided to hydraulic valves in the first and the second PODs that are controlled by corresponding SEMs.

    Abstract: A method of reducing hydraulic shock in a BOP system including a pressure regulator having an input port and an output port, and a regulator piston that moves between an open and a closed position based on a change in hydraulic pressure applied to the regulator piston via a pilot port. The method includes initiating a function, and monitoring the state of the function as it is carried out to predict when the function nears the end of its cycle. The method also includes, when the function reaches a predetermined state, adjusting the hydraulic pressure on the regulator piston via the pilot port to gradually move the regulator piston between the open to the closed position to reduce fluid flow through the fluid path in a controlled manner to reduce hydraulic shock.

    Abstract translation: 一种降低包括具有输入端口和输出端口的压力调节器的BOP系统中的液压冲击的方法，以及调节器活塞，其基于通过经由调节器活塞施加到调节器活塞的液压的变化而在打开和关闭位置之间移动 试点港 该方法包括启动一个功能，并监视函数的状态，以执行该功能以预测功能何时接近其循环结束。 该方法还包括当功能达到预定状态时，通过先导端口调节调节器活塞上的液压，以便将调节器活塞逐渐地在打开到关闭位置之间移动，以便以受控方式减少通过流体通道的流体流动 以减少液压冲击。
