Wellhead Shear/Blind Ram Assembly |
摘要 |
A shear/blind ram assembly for a subsea wellhead that is positioned between a blowout preventer system and the wellhead configured to selectively discontinue the flow of oil from the wellhead to the blowout preventer system. The shear/blind ram assembly includes a horizontally aligned main body with a vertical bore that is aligned and registered over the well bore on the wellhead. The main body includes a perpendicularly aligned lower neck and a perpendicularly aligned upper neck. Located inside each neck is a hydraulic ram unit which when activated discontinues the flow of a fluid through the main body's fluid. The main body also includes a lower connection flange surface formed on the lower neck configured to selectively connect to a wellhead connector and an upper connector flange formed on the upper neck and configured to selectively attached to a blowout prevention assembly. |

1. A shear/blind ram assembly for a backup blowout system, comprising:
a. a horizontally aligned main body that includes a perpendicularly aligned lower neck and a perpendicularly aligned upper neck, said main body includes a vertical fluid bore; b. two opposite hydraulic ram units located on opposite sides of said fluid bore that when activated discontinues the flow of a fluid through said fluid bore; c. a lower connection flange surface formed on said lower neck configured to selectively connect to a wellhead connector; d. an upper connector flange formed on said upper neck and configured to selectively attached to a blowout prevention assembly. |
