Features & specifications

  • Hydraulic Power System: Delivers and maintains hydraulic pressure to operate BOP stacks, ensuring quick response in emergency situations. Nominal operating pressure is typically 3000 psi (210 bar).
  • Dual Pump Setup: Features both electric and pneumatic pumps for operational redundancy. Each pump can be operated independently, providing reliability during workover operations.
  • Accumulator System: A bank of hydro-pneumatic accumulators stores energy for instantaneous release during BOP actuation. Available with 4 or 6 accumulator options.
  • Precise Control Manifold: Integrated control manifold provides easy regulation of hydraulic pressure for both annular and ram BOPs. The system is equipped with 4-way, 3-position valves for effective manual operation.
  • Air Compressor and Storage: Includes an internal air compressor and tank, ensuring the system can operate independently of external air sources, making it suitable for remote or offshore applications.
  • Quick-Connect Hoses: Comes with a full set of quick-connect hydraulic hoses, allowing fast and secure connection to the BOP stack, minimizing downtime and ensuring safety.
  • Remote Control Functionality: The unit can be operated remotely from a safe distance via a driller’s panel or remote console. Remote panels include visual and acoustic alarms to monitor system pressure and performance, ensuring operational safety.
  • Compact and Portable Design: The compact design of the unit makes it easy to transport and install on workover rigs, offering flexibility for both onshore and offshore operations.

Sizes and Pressure Ratings:

  • Available in multiple configurations with accumulator capacities up to 6 units, each rated for 3000 psi (210 bar).

Applications:

  • Workover Operations: Ideal for controlling well pressure during well servicing and workover procedures, ensuring safe and reliable hydraulic operation of BOP stacks.
  • Offshore and Onshore Rigs: Suitable for use in both offshore and onshore environments, offering flexibility and ease of use in various well control scenarios.

Materials and Construction:

  • Corrosion-Resistant Panels: Built with stainless steel or other corrosion-resistant materials to withstand harsh environments, ensuring long-term durability.
