Abstract
In one system, there is an emergency pipe stroker tool, wherein the emergency pipe stroker tool is configured to act as a first mechanical barrier for a well. Further, there is an emergency quick disconnect tool in communication with the emergency pipe stroker tool, wherein the emergency quick disconnect tool comprises a connector assembly and a fluid conduit in communication with the well, and further wherein the connector assembly is configured to simultaneously detach from the well and to seal the well. Further still, there is a cement retainer in communication with the emergency quick disconnect tool and the emergency pipe stroker tool, wherein the cement retainer is configured to act as a second mechanical barrier for the well, wherein, the emergency pipe stroker tool, the emergency quick disconnect tool, and the cement retainer act in coordination to seal a well while establishing the multiple mechanical barriers.
