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.

Well intervention disconnection system

Systems and methods presented herein include a subsea hose deployment winch having a spool configured to receive a subsea hose spooled thereon; and a mechanical intervention device launcher assembly configured to be directly coupled to an end of the subsea hose. The mechanical intervention device launcher assembly may be configured to facilitate insertion of a mechanical intervention device into the subsea hose while maintaining an isolation barrier to the environment.
