Abstract
Apparatuses and methods for erecting drilling structures including drill floors and drilling masts include attaching a rigging line to the drilling structure and to a strand jack arranged with at least one hydraulic jack and a plurality of clamps that alternatingly secure onto the rigging line and pull the rigging line in tension. Pulling the rigging line with the strand jack raises the drilling structures to an upright or elevated position.
