Patent ID: 6902199

Claim:
An apparatus for connecting a subsea flowline to a subsea connector hub, the connector hub having an end with a locking profile, comprising: a connector frame; a tubular mandrel carried by the frame and adapted to be connected to the flowline, the mandrel having an axis and an end that is adapted to engage the end of the connector hub, the mandrel being axially movable relative to the frame; a first engagement point that is stationary relative to the frame and a second engagement point that is movable with the mandrel and spaced axially from the first engagement point, the frame having an opening between the engagement points; a telescoping jack assembly that is releasably inserted into the opening, the jack assembly having opposite ends engaging the first and second engagement points; an ROV interface on the jack assembly that is engageable with an ROV for causing the jack assembly to move the engagement points axially relative to each other to move the end of the mandrel into engagement with the end of the connector hub; wherein the jack assembly comprises: a frame member; at least two parallel hydraulic cylinders mounted to the frame member, the cylinders being spaced apart from each other for location on opposite sides of the mandrel when installed in the opening; wherein the ROV interface is in fluid communication with the hydraulic cylinders for receiving hydraulic fluid pressure from an ROV to stroke the cylinders; and a section of buoyant material is mounted to the frame member for lightening the weight of the jack assembly in water.
