/Annular Blow Out Preventer
Abstract

An embodiment uses a symmetrical elastomeric design with hydraulic pistons on either end (as opposed to a single piston on conventional BOPs) which allows for lower actuation forces, reduced friction, and reduced wear and tear. The lower actuation forces correspond to lower operating pressures which allows the body and housing to be smaller, leading to a smaller footprint.
