Built to an enhanced version of Keppel’s proprietary KFELS Super A Class design, the rig has been contracted to Nederlandse Aardolie Maatschappij B.V. (NAM), an oil and gas explorer and producer focused in The Netherlands. Enhancements to the design include Ensco’s patented Canti-Leverage AdvantageSM technology, which provides cost advantages for customers by allowing them to drill more wells from one location when utilising the enhanced hoisting capacity at the farthest reach of the cantilever.
