    Primary attachment will be directly to top of blow-out preventer (BOP) stack forming tight pressure seal

    Stack is composed of conventional well control equipment assembled to allow 4 functions:

     Shut well in via blind rams (with redundancy)

     Flow well in controlled fashion to containment system

     Pump kill fluid down wellbore

     Re-enter well for well intervention activities
