Abstract
There is disclosed a subsea wellhead connector comprised of a lower tubular member mounted on the upper end of a lower wellhead member, and an upper tubular member suspended from an upper wellhead member for lowering into end-to-end connection with the lower tubular member. Locking teeth are formed about the ends of the tubular members, and circumferentially spaced locking segments are carried by the upper tubular member for movement radially into or out of locking engagement with the grooves about the upper and lower tubular members. The locking segments are moved inwardly to locking position by means of a cam ring which surrounds them, and are withdrawn from locking position by spreader dogs carried by the cam ring and extending between the ends of adjacent locking segments.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
