Abstract:
A method for capping a subsea wellbore having a failed blowout preventer proximate the bottom of a body of water includes lowering a replacement blowout preventer system into the water from a vessel on the water surface. The replacement blowout preventer system includes an hydraulic pressure source disposed proximate well closure elements on the replacement blowout preventer system. The replacement blowout preventer system is coupled to the failed blowout preventer. The well closure elements on the replacement blowout preventer system are actuated using the hydraulic pressure source.
