National Oilwell Varco Derricks

NOV designs and manufactures all types of derricks for platforms, jackups, semi-submersibles, and drillships. Whether supplying a standard derrick design or providing a new innovative designed product, each derrick is analyzed by our broadly experienced team of structural engineers specifically optimizing the design for its intended application taking into account required capacities, specific equipment, environmental considerations, and third party requirements. This allows NOV to create a solution that is tailored to realize the performance while reducing the unexpected surprises that can occur in any given application. The ability to create customized integrated rig solutions has led us to innovations such as the Hip Leg™ derrick and offset well center designs that allow for increased setback capacity and more efficient vessel loading. Other creative designs such as corner mounted top drives and top drive parking systems, have improved visibility of the driller and assistant driller while facilitating the most efficient use of space within the derrick and efficient operations with pipe handling systems. Within NOV we have brought together the history and experience of leading rig designers and manufactures such as DRECO™, IRI, Continental Emsco, and DSI, and we can offer the unique ability to provide the necessary solutions from designing upgrades to adding equipment and increasing capacities in any given oilfield application.
