Comparison of Cameron Ram-Type Blowout Preventers
Cameron offers a wide range of ram-type BOPs to meet the dynamic needs of the
drilling industry. The Cameron U BOP was initially designed for underwater drilling
and is now the most widely used land BOP. Today, there are more U BOPs in the
field worldwide than any other ram-type BOP in the industry. As technology and the
needs of the drilling industry changed, Cameron responded by developing new
ram-type BOP designs. Cameron introduced the U II BOP for subsea applications and
has since developed the T BOP and the TL, UL and UM models for land and subsea
applications. Regardless of the model, all of the pressure containing components in
Cameron ram-type BOPs are forged to provide added safety and reliability.
