1. A subsea hose deployment winch, comprising:
a spool configured to have a subsea hose spooled thereon; and
a mechanical intervention device launcher assembly configured to be directly coupled to an end of the subsea hose, wherein the mechanical intervention device launcher assembly is configured to facilitate insertion of a mechanical intervention device into the subsea hose while maintaining an isolation barrier to the environment, and wherein the mechanical intervention device launcher assembly comprises an emergency quick disconnect (EQD) device aligned axially with the end of the subsea hose when the mechanical intervention device launcher assembly is directly coupled to the subsea hose, wherein the EQD device is configured to passively disconnect a fluid path through the mechanical intervention device launcher assembly.
