The intermediate spool is connectable to the lower riser package spool to secure the subsea test tree within the bore of the lower riser package spool such that the lower riser package spool is in fluid communication with the intermediate spool. The riser stress joint is releasably connectable to the intermediate spool using such that the intermediate spool is in fluid communication with the riser stress joint.
