Abstract

There is disclosed an actuator for delivering a supplementary force to the piston of a shear ram in a blowout preventer (BOP), and a corresponding BOP. In one embodiment, a supplementary force actuator (12) is disclosed for use on a hydraulic ram (10), the actuator comprising an actuator body (30) connected to the hydraulic ram; first and second chambers (38, 36) located in the body, the chambers isolated from each other by an actuator piston (46); a rod (42) connected to an operating piston (24) of the hydraulic ram, passing through the first chamber and the actuator piston, and extending into at least a portion of the second chamber; wherein the actuator piston is releasably engageable to the rod by gripping means (48); and wherein the hydraulic ram is operated by a force from movement of the operating piston and by a supplementary force from movement of the actuator piston.
