Abstract
An intervention system is provided for a subsea well operation. The intervention system includes a first coupling portion, a second coupling portion releasably coupled to the first coupling portion, a monitor tether coupled to one of the first coupling portion and the second coupling portion, and a control system. The first coupling portion and the second coupling portion provide fluid communication while the first coupling portion and the second coupling portion are connected to one another. The monitor tether transmits an electrical current while the first coupling portion and the second coupling portion are connected to one another. The control system is operable to detect a change in current in the monitor tether indicative of disconnection between the first coupling portion and the second coupling portion, and, in response to detecting a change in current in the monitor tether indicative of disconnection, interrupt fluid flow relative to the subsea well.
