%X A new subsea completion system has been designed to combine conventional mudline installation of the 30 inch and 20 inch casings, with a new 13&#x215d; inch mudline housing, new 13&#x215d; ft inch nominal tubing hanger and seal flange. The 13&#x215c; inch mudline housing features external running threads and replaces the conventional 13&#x215c; inch casing hanger, the 13 inch tie back adapter and tubing spool. The new tubing hanger features production annulus access through a vertical bore in the hanger body. The main advantages include increased safety due to decreased diver-assisted operations and cost savings due to easier installation of the system compared to a conventional subsea system.
