Abstract: The present disclosure relates to a modular drilling cellar configured to be arranged beneath a drill floor of a drilling rig. The cellar may have a housing for storing well head equipment and a drill floor support structure. The drill floor support structure may have a pair of support legs, each leg may have an extension portion, a column portion, and a bearing foot. Each of the extension portion and column portion may be configured to be arranged in a reading position and an operating position.

Abstract: A drill rig having a drill pipe standbuilding system. The standbuilding system may have one or more offline mouseholes, such as two offline mouseholes, a hoist arranged on a rail system, and an iron roughneck. The rail system may be arranged on the mast, such as above a racking board. The hoist may extend from the rail system, through the racking board, and toward a drill floor of the drill rig. The offline mouseholes, rail system, hoist, and iron roughneck may allow drill pipe stands to be built without interrupting or slowing drilling operations. A method of standbuilding may include arranging a first pipe section in a first mousehole, arranging a second pipe section in a second mousehole, coupling a third pipe section to the second pipe section to form a double stand, and coupling the second pipe section to the first pipe section to form a triple stand.
