FKQ1800-14 BOP Control System With 1800L Accumulator Volume 14 Controlled Objects

The BOP control system is a critical equipment for preventing uncontrolled blowouts during oil and gas drilling (or workover operations). Its main functions include generating and storing high-pressure oil, controlling oil flow direction to drive BOP to open/close quickly, and maintain the set pressure range automatically.

Remote Control Type: Includes pneumatic control, electro-pneumatic control, electro-hydraulic control, wireless electro-pneumatic control, etc. Local manual control if remote control is not equipped.

Key Parameters: Covers the nominal total volume of accumulators and the number of controlled objects (BOP and hydraulic valves).

Design Identifier: Specific letters distinguish different design serial numbers, used to differentiate product iterations or customized versions.

Example: FKDQ800-7

• (1) FK: Surface BOP control system
• (2) DQ: Remote control type (Q = pneumatic control; DQ = electro-pneumatic control; DY = electro-hydraulic control; WDQ = wireless electro-pneumatic control; blank = no remote control, local manual control)
• (3) 800: Nominal total volume of accumulators (L), range: 40~1920 L
• (4) 7: Number of controlled objects (e.g., 2 controlled objects or 5 controlled objects)

• Master Control Unit: The key hydraulic unit responsible for generating, storing pressure oil, and controlling oil flow direction. Equipped with pump units, accumulator banks, and various valves, it supports automatic start/stop for pressure compensation to meet emergency shutdown requirements.
• Driller's Control Panel: Installed on the drill floor near the driller for quick operation. Supports multiple control modes (pneumatic, electro-pneumatic, etc.), provides real-time BOP status feedback, and decrease the control delay time.
• Remote Control Cables/Hoses: Classified into pneumatic hoses and electrical control cables, responsible for transmitting pressure signals, control signals, and power supply signals to ensure linkage between the master control unit and driller's control panel.
• Connecting Fittings (Optional): Include metal pipes and high-pressure hoses for delivering pressure oil to BOP cylinders and enabling return flow. Metal pipes offer high safety, while high-pressure hoses allow easy installation.

• Pressure Charging and Energy Storage: Dual pump units (electric pump + pneumatic pump) charge the accumulators. The pumps automatically stop when the pressure reaches the upper limit and restart to compensate pressure when it drops to the lower limit.
• Pressure Regulation: High pressure from accumulators is adjusted to BOP-compatible pressure via pressure regulators and other components, divided into annular control pressure and manifold control pressure.
• Control Modes: Supports manual control via the master control unit and remote control (pneumatic, electrical, wireless, etc.) via the driller's control panel. The rotate valve switching controls the flow direction of pressure oil to achieve BOP opening/closing.

• Installation Requirements: Must be operated by professionals. Equipment placement must comply with safety distance regulations; hydraulic pipes, cables, and other connections must be aligned according to markings; power supply and air source parameters must meet equipment specifications.
• Commissioning Operation: Includes pipeline air bleeding, accumulator pressure charging, automatic pump control, and pressure regulation to ensure normal linkage of all components and reliable sealing.
• Routine Maintenance: Maintenance cycles are set by work shift, weekly, monthly, and annually. Key inspection items include pressure values, sealing conditions, oil cleanliness, and nitrogen pressure. Seals and oil should be replaced promptly as needed.

• Environmental Adaptability: Normally suitable for temperatures ranging from -13°C to 50°C. Thermal insulation, cooling, or heating devices are required for extreme temperatures; pneumatic hoses need special protection in low-temperature environments.
• Safety Design: The driller's control panel requires two-hand operation to prevent accidental triggering, equipped with emergency facilities such as audio-visual alarms and backup pressure sources. Offshore platform equipment must meet moisture and corrosion resistance requirements.
