In 1922, Jim Abercrombie and Harry Cameron designed the world’s first blowout preventer (BOP) in the dust of the floor of their shop in Houston, Texas. The new invention revolutionized the fledgling drilling industry and soon, Cameron's BOPs were being used throughout Texas and as far away as Mexico and Venezuela.
In 1927, Abercrombie and Cameron went on to develop a BOP with rams that could be closed with steam or water pressure. And the firsts just kept coming. Cameron Iron Works later introduced BOPs with larger bore sizes and higher pressure ratings. In 1962, Cameron became the first company capable of designing and delivering a complete underwater drilling system. And in 1988, Cameron set a record for the delivery of sophisticated subsea BOP stack systems and electro-hydraulic multiplex (EH MUX) drilling controls systems.
