Patent Images
1. An offshore rig for operating at separate wells, the rig comprising:
- a hull positionable relative to the separate wells;
a cantilever assembly movably mounted relative to the hull; and
at least two operational assemblies each movably mounted independent of each other 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.

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.
