A method comprising attaching a first mast section to a support structure using a first plurality of fasteners located on the support structure, wherein a lower portion of the support structure is connected to and located above an opening in the platform comprising a platform floor, and wherein the first mast section has a line, a hook, and a pulley, with the line operably coupled to the pulley and connected to a hoist attached to the platform. The method also comprises lowering the hook, using the hoist, in a downward direction away from the pulley and through the opening, attaching the hook to a second mast section located below the platform floor, raising the hook and the second mast section, using the hoist, in an upward direction towards the pulley and through the opening, and connecting the first mast section to the second mast section. Additionally, the method comprises securing the first mast section and the second mast section with an overhead support located above the first mast section and connected to the first mast section, detaching the first mast section from the support structure, raising the first mast section and the second mast section away from the platform floor, using the overhead support, and attaching the second mast section to the first plurality of fasteners.
