ABSTRACT:
A manifold unit is connected to a running tool and pipe and run into position in a receptacle on a subsea template or platform to establish a flow path between fluid passages in the receptacle. Fluid supplied through the running pipe forces locking elements into locking engagement with the receptacle and the unit is forced into seating engagement in the receptacle to make a seal between the unit and the flow passages. The unit is retrievable by engaging another pipe in the unit and supplying pressure to release the locking elements.
