Abstract

See full text

A remotely operated submersible vehicle (ROV) is used to carry a bridge plug down to a sub sea well. The ROV is operated from a surface vessel or platform and is outfitted with a submersible hydraulic pump and a manipulator arm. Additionally, the ROV is provided with a carrying rack which can support a well closure assembly made up of an inflatable bridge plug and an affixed hydraulic running tool. The bridge plug and running tool are placed into the carrying rack and operably interconnected with the hydraulic pump so that the plug element can be selectively inflated by the pump.
