  • Patent number: 12152459
    Abstract: A technique facilitates reliable operation of a blowout preventer (BOP) system in a wide range of challenging environments. To enable dependable and rapid closing of the internal passageway of the BOP system, an annular closing system is employed. The annular closing system is fully electrically actuated and may comprise a variety of components which cooperate to provide reliable sealing of the internal passageway. Examples of those components comprise a packer which may be compressed inwardly to seal off flow along the interior passage. Additionally, a pusher mechanism is positioned in the annular closing system and is shiftable, e.g. linearly shiftable, such that its motion causes the packer to be compressed in the radially inward direction. At least one electrically operated rotary-to-linear actuator is actuatable to move the pusher mechanism when causing compression of the packer.
