Abstract
A tubing spool has an internal landing profile for a reduced diameter tubing hanger which is arranged and dimensioned to pass through the bore of a slimbore marine riser and BOP of a subsea completion system. The tubing spool is arranged and designed for securement to a wellhead at the sea floor. The tubing hanger is arranged and designed to be sealingly positioned in the tubing spool landing profile and has a production bore and a relatively large multiplicity of electrical and hydraulic passages which terminate at a top end of the hanger with vertically extending electrical and hydraulic couplers. A passage is provided, independent of the tubing hanger, which provides communication from above the tubing hanger to the well annulus below the hanger. The tubing spool may have a slim bore BOP or a conventional xmas tree attached at its top end.
