Abstract
A ram type blowout preventer is designed to provide substantial hang off capability. Improved hang off capacity is provided by the ram bodies having shaped upper centralizing lobes and/or semi-circular or U-shaped central openings. In particular, the interface between the upper centralizer lobe and central opening is tapered such that the hang off load is spread over a larger area of each ram body.
