ABSTRACT:
A subsea well assembly utilizes outer, intermediate, and inner wellhead housings. The inner wellhead housing has a port extending through it that communicates the annulus with the bore of the inner wellhead housing. A sleeve mounts to the inner wellhead housing for opening and closing the port. The port allows the operator to cement a string of inner casing, with returns flowing through the port and back up the bore of the inner wellhead housing.
