An apparatus for actuating a ram in a well pressure control apparatus includes an actuator rod coupled to a ram. The actuator rod is movable within a housing to extend the ram into a through bore in the housing. A drive screw is rotationally coupled to the actuator rod. The drive screw is oriented transversely to the actuator rod. At least one motor is rotationally coupled to the drive screw.

A method for excavating a well cellar includes lowering an excavating apparatus having a cellar liner therein to a bottom of a body of water. The well cellar is excavated while contemporaneously lowering the cellar liner into the well cellar until a top of the cellar liner is substantially level with the bottom of the body of water. A pilot well is excavated below a bottom of the cellar. A well head support pipe is inserted into the pilot well. The bottom of the well cellar and a top of the cellar liner are covered.
