Title: MULTI-WELL BOP CELLAR TRAILER
Abstract:
A drilling rig (400) having a detachable, modular cellar arranged beneath a drill floor of the drilling rig. The cellar may be or include a cellar trailer (100) and may be configured to house drilling equipment, such as well head equipment, such as one or more blowout preventers (125). In some embodiments, the cellar trailer may provide work areas, such that the well head equipment may be prepared, tested, or generally operated within the cellar trailer. The cellar trailer may additionally be configured to provide stiffening support to the drill floor in order to mitigate deflection of the drill floor during drilling operations. The stiffening support may be provided by a shear wall (108) extending from the cellar trailer. The cellar trailer may be towable. The cellar trailer may additionally be skiddable and/or walkable.
