Pressure control
BOP Control Units
Accumulator units and remote panels that close the BOP stack.
Overview
A blowout preventer is only as good as the system that closes it. BOP control units store hydraulic fluid under pressure in accumulator bottles, so the stack can be closed quickly even if rig power is lost.
Units are sized to the closing volumes of the specific stack they serve, with pumps to recharge the bottles and a remote panel at the driller's position as well as controls at the unit.
Key Features
- Accumulator bottle banks sized to stack closing volumes
- Electric and air-driven recharge pumps
- Driller's remote control panel
- Pressure regulation for annular and ram functions
Applications
- Surface BOP stacks on land and jack-up rigs
- Stack upgrades and replacement control systems
- Workover and well service units
