Abstract:
A blow out preventer includes a main body with a main passage arranged therethrough, a ram movable between a first ram position in which the ram is spaced from the main passage and a second ram position in which the ram at least partly interrupts the main passage, and a bonnet releasably secured to the main body. The bonnet includes a hydraulic ram actuator coupled to the ram. The hydraulic ram actuator includes a primary piston arranged within a primary cylinder and fixed to a piston rod, and a secondary piston arranged within a secondary cylinder to be slidable on the piston rod. The primary piston and the secondary piston are each arranged to actuate the ram via the piston rod. The primary piston and the secondary piston each comprise a stroke length, the stroke length of the secondary piston being shorter than the stroke length of the primary piston.

Claim (Index 51):
A blow out preventer comprising:\n a main body comprising a main passage arranged therethrough; a ram movable between a first ram position in which the ram is spaced from the main passage and a second ram position in which the ram at least partly interrupts the main passage; a bonnet releasably secured to the main body, the bonnet comprising a hydraulic ram actuator which is coupled to the ram; and a first extendable hydraulic supply line, the first extendable hydraulic supply line being arranged to provide hydraulic fluid from the main body to the hydraulic ram actuator in a bonnet open position and in a bonnet closed position.
