Configurable Subsea Tree Master Valve Block

摘要

A pre-machined forging for use with a subsea hydrocarbon assembly includes a common master valve block. The common master valve block has an upper cylindrical portion with a main central axis. A lower cylindrical portion of the common master valve block includes a lower axis that is parallel to, and offset from, the main central axis. A valve portion of the common master valve block is located axially between the upper cylindrical portion and the lower cylindrical portion. A main bore extends axially through the common master valve block from a bottom end of the common master valve block to a top end of the common master valve block along the main central axis.
