Abstract

A shear ram assembly for use in a BOP stack. The shear ram assembly includes a ram block disposed within the shear ram housing and having a forward end facing the bore, the ram block movable between an open position, in which the ram block is retracted away from the bore, and a closed position, in which the ram block is extended toward the bore. The blade has a forward surface, a rear surface, a lower shearing edge, and an upper edge, the blade attached to the forward face of the ram block by fasteners extending at an angle relative to an upper surface of the ram block through a portion of the ram block and into the rear surface of the blade, the rear surface of the blade angled so that it is perpendicular to the longitudinal axis of the fasteners.
