    摘要: A holding member provides for releasably positioning a rotating control head assembly in a subsea housing. The holding member engages an internal formation in the subsea housing to resist movement of the rotating control head assembly relative to the subsea housing. The rotating control head assembly is sealed with the subsea housing when the holding member engages the internal formation. An extendible portion of the holding member assembly extrudes an elastomer between an upper portion and a lower portion of the internal housing to seal the rotating control head assembly with the subsea housing. Pressure relief mechanisms release excess pressure in the subsea housing and a pressure compensation mechanism pressurize bearings in the bearing assembly at a predetermined pressure.

    摘要: A hydraulic locking system for a blowout preventer function is provide. The locking system enables implementation and practical engagement as part of the routine functioning of the blowout preventer. The locking system may be adapted to fluidly interconnect a control system port and a function port so as to trap and release hydraulic actuation pressure against the function port and any blowout preventer function fluidly communicating thereto.
