Emergency Disconnect Package
Subsea equipment package that typically forms part of the lower workover riser package and provides a disconnection point between the riser and subsea equipment. NOTE This equipment is used when it is required to disconnect the riser from the well, typically in case of a vessel drift-off or other emergency that could move the vessel away from the well location.
