Abstract: A jumper for transferring fluids from an umbilical to a subsea tree assembly has a plurality of steel tubes. The steel tubes are bent so that the jumper is in a serpentine or w-shape while in a natural state. The steel allows resists damage to the jumper from the fluids and chemicals being transferred to the tree assembly. The w-shape of the jumper allows the jumper to be stretched or contracted so that the distance between the connectors on each end of the jumper can vary. The contracted width jumper is attached to a terminal plate located on the tree assembly as it is landed on a subsea wellhead. An ROV disconnects the jumper and connects the jumper to receptors on the tree assembly and the umbilical, while stretching the jumper to the necessary length to reach the receptors. The jumper can be disconnected from the tree assembly when maintenance is necessary without moving the umbilical.

Abstract: A tool lands a flowline connector on a base and soft land the connector to a mandrel. After the tool lands on the base, the tool locks to the base and then pushes the connector the mandrel until it abuts locks to the member. The tool has at least one ring assembly with a number of dogs per ring assembly. Each dog moves in unison with a follower relative to a cam ring in a slot. The movement along the slot moves the dogs radially and circumferentially relative to the cam ring. An actuator moves a follower ring that slides relative to the cam ring which moves the follower. Each dog remains in contact with the cam ring after moving radially inward because of protuberances on each dog that slide from a recess as the dog moves circumferentially and radially inward.
