A dual line drawworks system and methods of using the same. A drilling rig may include two drawworks, each attached to a drilling line that extends through a series of sheaves located on the crown block and a traveling block. One end of the drilling line may be attached to an anchor. The traveling blocks may comprise a series of split blocks which may be separately movable from one another and may be removably attached to an underside of the crown block. The two drawworks may be coupled to one another and to one or more control systems, which may include one or more variable frequency drives, and the two drawworks may be configured to operate at the same speed. Systems may be used to monitor the distance between the traveling blocks and detect and correct for any excess distances therebetween.
