Abstract
A subsea connector is remotely actuated to connect a subsea flowline to a subsea connector hub. The connector has a frame with a tubular mandrel located within it. The mandrel connects to the flowline and has a forward end that engages the connector end. The mandrel moves axially relative to the frame between retracted and extended positions. A lock member on the forward end of the mandrel will engage the profile of the connector hub. An actuator mounted to the mandrel causes the lock member to move into engagement with the connector hub after the mandrel has been moved into engagement with the connector hub. A portable telescoping jack assembly has an ROV interface for receiving power from the ROV. The jack assembly fits within a first pocket in the frame to move the mandrel to the extended position. The jack assembly is retrievable from the first pocket and fits within a second pocket in the frame to move the actuator and the lock member into locking engagement with the profile.
