• Block Control System

    NOV engineers integrated our proven MD Totco™ instrumentation and sensor technologies with the powerful Baylor 2025B eddy brake control to create a closed-loop block control system (BCS) that overcomes the inherent deficiencies of traditional crown/rig floor savers and kinetic energy devices. The closed-loop control technology allows our system to constantly calculate when to apply the eddy current brake, while continuously measuring the effect of the brake’s application and adjusting the force accordingly.

    Features/Benefits

    Closed-loop control and passive operation  

    • Provides positive block control over the entire range of travel
    • Operates in the background, only providing the driller with control when necessary

    Crown/rig floor saver—driller establishes upper and lower limits 

    • Helps eliminate unplanned events and costly consequences

    Monkeyboard protection 

    • Avoids collisions by stopping the blocks with link tilt extended beyond a desired range when approaching the monkeyboard

    Block positioning and speed control 

    • Enables faster trips and connections
    • Maximizes operational efficiency and protects against swab and surge effects
