Brief: This video provides an informative breakdown of the Hydril MSP BOP disassembly process. We take a focused look at the specifications and what they mean in practice, covering the annular blowout preventer's core components, modular design for maintenance, and operational procedures for onshore drilling safety.
Related Product Features:
  • The Hydril MSP BOP features a 29 1/2" bore and 500psi working pressure for reliable pressure control in oil and gas drilling.
  • It utilizes a reinforced elastomer packing unit for full-coverage sealing of various downhole components without needing dedicated parts.
  • Well pressure-assisted sealing design enhances reliability through hydraulic initial sealing and pressure reinforcement.
  • Supports dynamic operations including drill pipe rotation and tool joint stripping with minimal fluid leakage.
  • Modular structure with Screwed Head or Latched Head designs enables quick disassembly and efficient maintenance.
  • Offers packing unit material options: Natural Rubber for water-based fluids and Nitrile Butadiene Rubber for oil-based fluids.
  • Complies with API Spec 16A and NACE MR0175 standards for sour service compatibility and safety.
  • Features a hydraulic control system with specific pressure recommendations for sealing pipes and open bore restrictions.
FAQs:
  • What is the maximum working pressure for the Hydril MSP BOP Diverter?
    The Hydril MSP BOP Diverter has a rated working pressure of 500 psi (3.5 MPa) and a hydrostatic test pressure of 750 psi (5.7 MPa).
  • Can this BOP seal an open bore during drilling operations?
    No, sealing of open bore is prohibited with this model. The minimum sealing diameter is 5" pipe, and specific hydraulic control pressures are recommended for pipe sealing.
  • What are the material options for the packing unit and how do they differ?
    Two material options are available: Natural Rubber (NR) for water-based drilling fluids with a service temperature down to -30°F, and Nitrile Butadiene Rubber (NBR) for oil-based fluids stable below -7°F. They are distinguished by color ribbons - red for NR and blue for NBR.
  • How does the well pressure-assisted sealing design improve safety?
    This design provides dual protection: hydraulic actuation creates initial sealing, while well pressure from below the packing unit further enhances the seal. If well pressure exceeds a critical value, it can maintain sealing without additional hydraulic supply, offering emergency protection during system failures.
