  • Patent number: 9068418
    Abstract: This invention is a hydraulic operated pipe pincher. It has a head segment having two hydraulic jacks linked with said head section, a sliding die head housing with said jacks connected to said sliding die head and a foot segment having a die linked with said foot segment. A boat is located on the surface of the water above where the pipe is to be pinched is located. The pipe pincher would be lowered and positioned around the pipe by way of a manipulator arm on a deep water submarine. The sliding die head would then be forced down against the pipe to pinch the pipe closed to restrict or nearly stop the flow of oil within the pipe. The dies are shaped to compress the pipe from each side equally.
