Abstract

Embodiments disclosed include BOP systems and methods for actuation of a BOP function by manipulating a component associated with a BOP. Embodiments of the disclosed BOP systems and the methods of operation of the BOP systems are further configured to monitor and/or control the actuation of a BOP function, by receiving information related to the actuation from a set of sensors associated with the component. Embodiments of the systems and/or methods include modeling actuation of the component; the actuation of the component being based on analyses derived from the modeling.
