• Self-Propelled Mobile Rigs

    Our Self-Propelled Mobile Rigs set the standard for reliability, safety, and overall quality.

    Description

    The New National Oilwell Varco™ Mobile Rig Product Line is a result of intentionally listening to our customers and producing rugged rigs that withstand the physical demands of the industry with a focus on safety.  The new designs increase the safety level by interfacing the advanced machinery with technologically, improved controls, and easier to read digital instrumentation. This combination allows the operator to work more efficiently in an environment that affords unprecedented control of user-friendly equipment, thereby reducing the stress and fatigue of the operator.  All of this is accomplished by offering products that are cost effective to the customer, both at the time of initial purchase and throughout the life cycle of the equipment.

    Features/Benefits

    • A basic rig design that offers excellent value and proven dependability at market pricing
    • New masts are equipped with rod transfer systems (certain models only), tong positioners and delayed racking board deployment, where applicable, to enhance safe operations and reduce operator fatigue
    • OSHA compliant handrails and walkways
    • Gear ratios may be set to customer specifications to match area road conditions
    • Placement of control panels that are located precisely to provide clear view of racking boards, traveling equipment and work floor operations on all well servicing, work over and drilling rigs
    • Controls are ergonomic set to assure maximum operator efficiency, while minimizing unwanted distractions
    • New rigs are designed in accordance with the applicable local standards, in addition to the American Petroleum Institute (API) and the American Institute of Steel Construction

    Specifications

     Advanced Technology Rig:

    • A new drawworks design eliminates the jackshaft, improving maintenance and providing a quieter, safer work environment while retaining the benefits of the jackshaft
    • Four cycle, electronically controlled engines reduce noise and are coupled to electronically controlled transmissions for maximum efficiency over a range of speed and pressure requirements
    • NOV's newly designed mast line is manufactured from high-strength, cold drawn seamless square tubing.  Square tubing allows the maximum load carrying capacity with desired torsional stiffness while minimizing mast weight
    • New masts are designed with a reduced profile that lowers the center of gravity and enhances safety while moving
    • Built-in steps on both sides of carrier improve accessibility to deck
    • A larger, safer work platform, enhanced by Grip Strut flooring and fold out wings
    • Additional working room at the crown block area for enhanced safety and reduced fatigue
    • New design extended length level jacks are provided. These are equipped with terrain adjusting crane-type pads eliminating the need for jack stands, improve safety, and allow faster rig-up
    • Improved surfacing (Fibergate™) on all walkways for safer footing and lower weight
    • Low entry, dropped profile cab, providing ease of entry and improved visibility 

    OEM Service, Repair, and Refurbishment:

    • Refurbishments and repairs are performed to exacting customers specifications and/or NOV recommended practices, which meet or exceed industry standards
    • NOV's "Fits-All" line of replacement masts are available to fit most mobile rigs
    • In addition to OEM brands, NOV refurbishes and provides services for all major brands of mobile rig equipment

    Other

    Kinetic Energy Control System (KECS) (Optional)

    • PLC based instrumentation and controls increase the functionality of the engine, drawworks clutch and brakes
    • Electric over hydraulic/pneumatic operation of the drawworks, engine and brakes, ensure maximum safety and requires less physical exertion on the operators, reducing the likelihood of fatigue induced accidents
    • Alarms and monitoring of selected rig parameters enable the operator to make more informed decisions
    • Stainless steel NEMA 4X enclosures are suitable for use in hazardous areas
    • Resilient mountings protect against shock and vibration
