Abstract
An annular blowout preventer (BOP) includes a housing comprising a bore extending through the housing, an annular sealing element configured to be displaced inwardly into the housing bore, and an actuating member configured to be actuated radially or perpendicularly with respect to an axis of the annular sealing element to compress the annular sealing element inwardly into the housing bore.

A method of actuating an annular blowout preventer (BOP) including a BOP housing, comprising:
- compressing an annular sealing element radially inward into a bore extending through the BOP housing by actuating an actuating member positioned about at least a portion of the annular sealing element in a direction perpendicular to an axis of the bore to apply only a radial force to a plurality of camming members that are distinct from the actuating member and positioned between an inner surface of the actuating member and an outer surface of the annular sealing element and rotatable about an axis parallel to the bore to distribute the force from the actuating member to the annular sealing element, wherein the actuating member comprises at least one of a cable, a wire, or a line and actuating the actuating member comprises rotating the actuating member to cause the plurality of camming members to move relative to one another to distribute the force to the annular sealing element;
- and
- forming a seal with the annular sealing element within the BOP housing.
An annular blowout preventer (BOP), comprising:
- a housing comprising a bore extending through the housing;
- a unitary annular sealing element configured to be displaced inwardly into the bore;
- an actuating member positioned within the housing and positioned at least partially about the unitary annular sealing element and actuatable in a direction perpendicular to an axis of the bore to apply only a radial force to compress the unitary annular sealing element inwardly into the bore;
- and
- a plurality of camming members that are distinct from the actuating member and are positioned between an inner surface of the actuating member and an outer surface of the unitary annular sealing element and rotatable about an axis parallel to the bore to distribute the force from the actuating member to the unitary annular sealing element;
- wherein the actuating member comprises at least one of a cable, a wire, or a line.
