Abstract
A wellhead system diverter spool contains an internal sleeve that can be axially shifted internal to the spool with a handling tool. The sleeve permits access to outlets in the spool when required. When higher pressures are required, the internal sleeve is shifted downward to close off access to the outlets without change out of equipment or changing the BOP stack riser system. The low pressure lines connected to the outlets can remain installed but are isolated from the higher pressure BOP stack pressures.
