The initial design was based heavily on new conceptual machines from new pipe handling to top drives to roughnecks and slips. Later, a complete redesign incorporated the use of as much existing equipment and technology as possible, and to redesign the package so that it would be much more mobile. The design intent was to minimize as much risk in the development and implementation as possible by using 90% existing equipment and systems, and rearrange them to optimize the drilling process.
