A subsea hydraulic system comprises a dual (or dual action) check valve on a port for connection to a remotely operated vehicle (ROV). The check valve provides backpressure to flow in either direction. This keeps hydraulic fluid in the hydraulic system, and seawater out. If flow needs to return to the ROV, it may flow out the port, subject to a selected back pressure.

A controls bridge for a flow completion system which comprises a tubing spool having a production outlet, a tubing hanger having a production bore that communicates with the production outlet and at least one service and control conduit extending therethrough, and at least one external service and control line that terminates near the tubing spool, the controls bridge comprising a first body portion; a mechanism for securing the first body portion to the top of the tubing spool and/or the tubing hanger; at least one first coupling member which is adapted to engage a second coupling member that is mounted in the service and control conduit; at least one third coupling member which is adapted to engage a fourth coupling member that is connected to the external service and control line; a bridge line which is connected between the first coupling member and the third coupling member; a first actuator for moving the first coupling member into engagement with the second coupling member; and a second actuator for moving the third coupling member into engagement with the fourth coupling member; wherein the first and second actuators are selectively operable to connect the service and control conduit to the external service and control line through the coupling members and the bridge line.
