Abstract
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.
