ABSTRACT:
A subsea well intervention system that permits dynamic disconnection from subsea well intervention equipment without removing any of the equipment during a drive-off condition is provided. The system includes a blowout preventer module operatively connected to a subsea tree, a lubricator assembly attached to the blowout preventer module that provides access to the interior of the blowout preventer and the subsea tree by well intervention equipment, and an umbilical module including a fail-safe disconnect assembly. The fail-safe disconnect assembly is disconnected using hydraulic power provided by the control umbilical or by a remotely operated vehicle.
