Abstract
An embodiment of a blowout preventer system of the present invention includes a mast functionally connected a frame assembly and a carriage functionally connected to the mast. The carriage is adapted to carry and support a blowout preventer in a manner such that the blowout preventer may be moved along an angular path and along a plurality of linear paths. The system may further include a mechanism for rotating the blowout preventer along a first rotational path. The system may further include a mechanism for rotating the blowout preventer along a second rotational path.

A BOP system for positioning and supporting a BOP relative to a wellhead, the system comprising:
- a mast functionally connected to a frame assembly;
- a carriage functionally connected to the mast;
- a vertical rotational drive mechanism in functional connection with the carriage for moving the BOP along a substantially arcuate path, and
- a second angular positioning mechanism functionally connected to the carriage for providing further movement along an angular path,
- wherein the carriage is adapted to carry and support a BOP in a manner such that the BOP may be moved along the angular path, along a plurality of linear paths, and along the arcuate path.
