<p>A flexible conduit is adapted for use subsea by providing the flexible conduit, comprising a non-carcassed, collapse resistant control line further comprising a reinforcing carcass, with a first valve disposed at a first end of the control line and a second valve disposed at a second end of the control line. The second end is disposed at a predetermined depth subsea. Once deployed, the first valve and the second valve are selectively engaged and/or disengaged to maintain a predetermined pressure of fluid inside the flexible conduit. In certain embodiments, the second valve, at a detected fluid pressure, is moved to a predetermined position which allows fluid inside the flexible conduit to be vented subsea, downstream of the second valve, through a vent port.</p> |
