Shell and Noble Corp. have announced the Gulf of Mexico arrival of the Noble Bully I, a state-of-the-art offshore drilling rig that is designed to raise the bar in terms of safety and performance. The Noble Bully I is the first of two Bully rigs, jointly designed by Shell and Noble, and can be equipped to drill in up to 10,000-feet of water. The Bully rigs also feature a compact box-type drilling tower, known as a multi-purpose tower, instead of a conventional derrick. As the name indicates, a multi-purpose tower is designed to maximize productivity and safety, yet it allows for a significantly smaller vessel when compared to other deep water drill ships of similar capacity. The ships also feature an attention to energy efficiency, use less fuel and are shorter and lighter than comparable drill ships.
