Abstract
A subsea wellhead assembly is disclosed with an extension spool secured thereto and an in line tree assembly locked within the extension spool. Ball valves are disposed within the vertical bores of the in line tree assembly. Valve actuators are disposed radially on the extension spool with a cylindrical sleeve mounted coaxially around the one end of the actuator and rotatable relatively to the actuator about the common axis of the actuator and the sleeve, so that, when the actuator engages with the corresponding ball valve, the sleeve bridges the gap between the extension spool and the in line tree assembly to lock the in line tree assembly to the extension spool.
