Disclosed herein in example embodiments is a simple Drill-Through-Equipment (DTE) system for deep water drilling of oil, to intervene in the event of Blowout Preventer (BOP) failure, and mitigate spill disaster. Example embodiments of systems and methods of failed BOP intervention, and oil spill disaster mitigation disclosed herein may be used to mount a housing within the existing BOP below the blind shear ram, whereby the failed BOP is made accessible just below the blind shear ram through access ports, opening or closing in the housing. Through these ports blowout is diverted, thus protecting the rig. Through these same ports access is granted to the drill pipe allowing external manipulation or cutting of the drill pipe in effort to render the BOP operational. Once this is accomplished, the access ports are closed, and normal BOP and/or drilling operations are resumed. Example embodiments integrate and make use of existing BOP machinery. |
