Patent ID: 7383887

Claim:
A method for rapid installation of a high pressure assembly threadably usable on an annular or ram type blow out preventer comprising the steps of: a. installing a flange with a threaded profile upon an annular blow out preventer with a bore and annular seals; b. installing a bell nipple on the flange; c. installing nuts over studs and tightening the nuts; d. installing a first test plug in a base of the annular blow out preventer or a base of a stack of annular blow out preventers; e. installing a second test plug into a threaded profile of the flange; f. performing a pressure test on the flange and all sealing aspects of the annular blow out preventer; g. depressurizing the flange and removing the first test plug; h. installing a thread protector between the flange and the bore of the annular blow out preventer; i. initiating drilling operations; j. upon indication of a need for small bore operations, installing a high pressure assembly comprising: i. an upper body and a lower body with a bore that communicates between the upper body and the lower body; ii. a top flange connected to the upper body for connection with a pressure control device; iii. a side outlet port disposed in the upper body, integrally connected to the bore having a port body and a side flange, wherein the side flange engages a line for pump in or bleed off of well fluids; iv. a two-part self energizing hold down assembly comprising: a male engagement section disposed between the upper body and the lower body; a threaded flange for connecting to the two-part self energizing hold down assembly comprising a female engagement for threadably engaging with the male engagement section of the two-part self energizing hold down assembly; and v. wherein installing the high pressure assembly comprises the steps of: 1. removing a thread protector; 2. threadably engaging the male engagement section of the two-part self energizing hold down assembly with the female engagement section of the flange; and 3. torquing the high pressure assembly until the high pressure assembly is mechanically locked in the flange.
