Annular bop buffer accumulator Introduction
The closing time of annular BOP preventers The main disadvantage of the annular preventer in a drilling rig is the time required to close it. The annular preventer takes three to ten times the fluid volume to close, compared to a set of preventer rams, and therefore requires a longer closing time. Even though current.
