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 and a subsea control system. The subsea control system is connected via electrical jumper to an ROV's tether management system. The subsea control system is connected via hydraulic jumpers to a multipurpose fluid-injection skid and one or more hydraulic accumulation banks. A fail-safe disconnect assembly is utilized with respect to the electrical jumper in order to provide easy removal during a drive-off condition.

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.
