ABSTRACT:
A rotating blowout preventor is comprised of a rotating head assembly which is removably received at the upper end of a main housing. The rotating parts of the head assembly are held fastened together by the provision of a unique locking plate arrangement. An internal bearing chamber is formed within the head assembly and is protected from contamination by an unobvious arrangement of the coacting parts which form the rotating head. The head assembly can rapidly be disassembled without the use of special tools, thereby making field repair of the apparatus possible. The main housing has a replaceable washpipe and seat that likewise is easily field replaceable.
