Abstract
An apparatus for installation to a subsea equipment mandrel or hub, including a body having a cylindrical sidewall defining one or more receptacles and a locking system to couple the body to the mandrel or hub. The locking system may include one or more locking assemblies received within a respective receptacle and coupled to the cylindrical sidewall. Each locking assembly may include a locking body, a locking collar, an annular seal, an actuator, and a locking pin. The annular seal may be seated within an annular groove and configured to engage the shoulder of a receptacle in a sealing relationship, and the locking collar may couple the locking body to the cylindrical sidewall. The actuator may be adjustably coupled to the locking body and configured to move radially. A locking pin may be configured to selectively engage the angled shoulder surface of the mandrel or hub.
