Remotely operated annular control device

HOLD ROTATING CONTROL DEVICE system
HOLD device with riser containment kit.

The HOLD remotely operated annular control device is the industry’s first RCD to include a remotely operated clamping system for improved safety in wellbore fluids containment applications.

The hydraulically operated lockdown mechanism for the sealing element can be operated by the driller from a control console on the drill floor. The console keeps the clamp locked down and prevents it from opening in the presence of wellbore pressure. Remote clamp operation eliminates the need for personnel below the rig floor, improving safety and reducing the time required to change out seal elements.
