Abstract
A bonnet assembly for a blowout preventer uses a seal carrier that is removable so as to allow for efficient and easy seal replacement. The seal carrier has: a recess adapted to at least partially embed a seal for sealing the bonnet assembly to a body of the blowout preventer; and a first connecting rod coupled to and extending from an inner surface of the seal carrier, where the first connecting rod has a fastening structure proximal to a distal end of the first connecting rod, where the fastening structure is adapted to engage with a first fastening device, and where the seal carrier is removable from the bonnet assembly when the first fastening device is disengaged from the fastening structure.
