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 linearly shiftable such that its linear motion causes the packer to be compressed in the radially inward direction. Electrically operated linear actuators are positioned and selectively actuatable to shift the pusher mechanism linearly when causing compression of the packer.
