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 electronically actuated annular closing system is employed. The annular closing system may include, for example, a packer combined with a shift mechanism actuatable to compress the packer inwardly so as to seal off the internal passageway. An electronic actuator is coupled with the shift mechanism to enable selective actuation of the shift mechanism to achieve the sealed closing of the internal passageway.
