Abstract
A coiled tubing string may be moved into and/or out from water by deploying an open water coiled tubing control system at sea such as via a vessel. The open water coiled tubing control system comprises a reel configured to accept a coiled tubing string, a surface injector, a reel tensioner configured to control an arch formed by the coiled tubing string between the reel and the surface injector, a controller, a subsea assist jack, and a predetermined set of a predetermined set of sensors. Motion of the surface injector and the subsea assist jack are used in part to move the coiled tubing string accepted by the reel into and/or out of a subsea well by receiving various information at the controller from the predetermined set of sensors and using the controller to resolve the received information to move the coiled tubing string into or out from the subsea well at a predetermined desired speed to achieve an outcome commanded by a single input from an operator.
