1. An offshore rig for operating at separate wells, the rig comprising:
- a hull positionable relative to the separate wells;
a cantilever assembly coupled to the hull and movably mounted in a plane relative to the hull; and
at least two operational assemblies coupled to the cantilever assembly, each movably mounted independent of each other in the plane relative to the cantilever assembly and to the hull,the at least two operational assemblies being operable to conduct separate operations of the separate wells independent of one another in both time and space,wherein the cantilever assembly comprises an equipment handling assembly handling operational equipment for the at least two operational assemblies and being shared between the at least two operational assemblies moved independent of each other in the plane relative to the cantilever assembly and to the hull.

Abstract
A dual tower rig includes a hull supported by one or more legs and includes a cantilever assembly coupled to the hull. Dual towers are supported by a skidding system that is coupled to the cantilever assembly. The towers are configured to conduct independent operations and are movable relative to each other and to the hull by the skidding system and the cantilever assembly.
