Dual multi-purpose tower engineered to cut ultra-deepwater well delivery costs

Any root cause analysis of the year-over-year reductions in operators’ return on capital employed (ROCE)—an economic malady aggravated by today’s appreciably lower commodity prices—falls squarely on flat times that are all-too-emblematic of deepwater and ultra-deepwater drilling rigs. Accordingly, the intensified demand for improvement in drilling efficiencies has inspired a step-change advancement in the form of a new-generation drillship design, integrating an enhanced version of the ground-breaking Dual Multi-Purpose Tower (DMPT), with built-in efficiencies, engineered to slash non-productive time (NPT), while elevating HSE profiles. Bearing little resemblance to a typical derrick, the pioneering DMPT builds upon proven technologies, with the incorporation of a myriad of new-age efficiency drivers, highlighted with genuinely automated tripping and robotic pipe handling. Furthermore, unlike traditional drilling systems, the advanced drilling package features the capacity to run 180-ft stands of drillpipe and casing and 150-ft riser joints; separate drilling and construction well centers to permit concurrent operations; dual-skiddable rotary hang-off tables; no V-door imitations; no cut-n-slip requirements and redundant heave compensation systems, among others.
