Abstract (en)
A lock system for a blowout preventer (BOP) includes an annular body, a movable rod positioned within the annular body, and an annular chamber defined between the annular body and the movable rod along a radial axis. The lock system also includes a locking sleeve positioned within the annular chamber, wherein the locking sleeve is configured to deform along the radial axis from a first position in which the locking sleeve blocks movement of the movable rod relative to the annular body and a second position in which the locking sleeve enables movement of the movable rod relative to the annular body. The lock system further includes a preload system.
