Abstract

A system for locking a bearing assembly to a rotating control device (RCD) housing is provided. The RCD housing can be coupled to a blowout preventer, and the bearing assembly can be received within the housing, and can comprise a stationary bearing housing having a perimeter channel. A plurality of locking block assemblies are each supported by the housing and are operable between a locked position and an unlocked position. Each locking block assembly comprises a movable block configured to interface with the perimeter channel when in the locked position, and at least one elastic component is situated between the housing and the movable block. The at least one elastic component is configured to automatically bias the movable block in the locked position. Upon supplying fluid pressure via a valve device, the movable block moves to the unlocked position and the at least one elastic component compresses to facilitate removal of the bearing assembly from the RCD housing. Associated systems and methods are provided.
