The Ram Blowout Preventer (BOP) is the most widely used. Its simple, compact design makes it well suitable for subsea or surface drilling operations. The Ram assembly provides a pressure-energized seal with maximum contact area to the drill pipe, casing, or tubing. This ensures a lower rubber pressure to the pipe and increase seal life.
