摘要： A marine riser coupling assembly includes bolted flanges (26, 28) with a raised face (30) around the inner edge and a raised face (32) around the outer edge. In the area of the bolt holes (38), there is a recess (34) between the two raised faces around the entire circumference. Bending strain of bolts (42) is thereby reduced.

摘要： A seal assembly for a wellhead housing and wellhead connector will seal even if the primary sealing surface becomes damaged. The wellhead connector and the wellhead housing each have primary sealing surfaces. A seal ring with upper and lower conical surfaces will seal against the surfaces of the wellhead connector and the wellhead housing. The wellhead housing also has a secondary sealing surface that extends down from the primary sealing surface. In the event that the primary sealing surface becomes damaged, a seal is utilized that has a support section and a lower seal surface. The support section does not sealingly contact the damaged primary seal surface on the wellhead housing. The lower seal surface engages the secondary seal surface of the wellhead housing to perform sealing.

摘要： A wellhead housing has features to increase the load carrying capabilities. The wellhead housing has a inclined load shoulder. A lower casing hanger which supports the outer string of casing is supported on the load shoulder. A landing profile locates between the load shoulder and the casing hanger. The landing ring has a cylindrical portion both above and below the load shoulder. These cylindrical portions restrain the material of the wellhead housing from yielding downward and inward. Also, a support ring encircles the wellhead housing on the exterior radially outward from the load shoulder. The support ring is fitted to the wellhead housing in an interference fit to provide a preload compressive force. Additional casing hangers for intermediate and inner strings are supported on the lower casing hanger.

摘要： A pipe connector with helically threaded (49, 57) frustoconical pin (10) and box (30) surfaces. The connector is axially (78) snapped together, but is rotated for disengagement. Centralizing surfaces (150, 152) on each thread form abut opposing crests (62, 54) to maintain concentrically, thereby detering disengagement under bending moments.

摘要： A metal seal for a wellhead assembly has upper and lower legs extending in opposite directions from each other and a rib extending radially outward from a junction of the legs. A first conical band on the upper leg extends uninterrupted from the rib a selected distance toward a tip of the upper leg. A second conical band on the upper leg extends uninterrupted from the tip of the upper leg toward the first conical band. An annular recess is located between the first and second conical bands. The lower leg also has two conical seal bands separated by a recess.

摘要： A subsea wellhead connector has an upper body that abuts the rim of a wellhead member. A hydraulic wellhead connector is carried by the upper body and extends over the wellhead member. The hydraulic wellhead connector carries dogs for moving into an engaged position with a profile on the exterior of the wellhead member. The mating or complementary stepped profile at the top or rim of the wellhead housing is designed to engage at three surfaces. The first surface is the flat surface at the inner diameter. The second surface is the tapered surface at the step. The third surface is the flat surface on the rim from the tapered surface to the outer diameter of the rim. The profiles are dimensioned with bias toward initial contact at the outer diameter flat on the rim of the well housing, second contact is at the inner diameter flat on the rim of the well housing, and the third contact is at the tapered step. Additionally, after preload, a lower portion of the lower body of the wellhead connector engages a stepped profile at the outer diameter of the wellhead, thereby creating a secondary load path for reacting to the applied bending moment.
摘要翻译： 海底井口连接器具有邻接井口构件的边缘的上主体。 液压井口连接器由上主体承载并且在井口构件上延伸。 液压井口连接器携带用于移动到接合位置的狗，其具有在井口构件的外部上的轮廓。 在井口壳体的顶部或边缘处的配合或互补的台阶轮廓被设计成接合在三个表面上。 第一表面是内径处的平坦表面。 第二个表面是台阶处的锥形表面。 第三表面是从边缘的锥形表面到边缘的外径的边缘上的平坦表面。 型材的尺寸设计为在井壳的边缘上的外径平坦处的初始接触的偏压，第二接触处在井壳的边缘上的内径平坦，并且第三接触处于锥形步骤。 此外，在预压后，井口连接器的下部主体的下部在井口的外径处接合阶梯轮廓，由此产生用于对所施加的弯矩作出反应的次级承载路径。

摘要： An adjustable wellhead connector is secured to the lower end of a BOP and riser assembly and has a housing which surrounds a groove profile on the upper outer surface of a first wellhead housing. The housing has a window on its inner surface which contains a removable first locking member. The first locking member has a groove profile on its inner diameter which mates with the groove profile on the first wellhead housing. The first locking member is movable between inner and outer radial positions which correspond to locked and unlocked positions, respectively. The first locking member is moved by a hydraulic system contained within the housing. The wellhead connector may be readily adapted to connect to a second wellhead housing having a different outer diameter than the first wellhead housing by replacing the first locking member with a second locking member. The second locking member enables the wellhead connector to connect a riser to the second wellhead housing.
