Abstract
Two or more rotating towers on a drilling rig may be configured to rotate between one or more wells. The rotating towers may have a common well center, such that the two or more towers can operate over the same well to provide redundant or cooperative operations. Some example cooperative operations include heavy lifting and/or isochronous tripping operations. Redundancy can be provided by the two or more rotating towers to prevent equipment failures from halting operations.
