A Xmas Tree design configured with master valves and swab valve in the vertical bore(s). The tubing hanger is landed inside the wellhead or THS. The vertical tree is then installed after well barriers are set and the drilling BOPs and marine riser are pulled. The completion is installed before the VXT is installed. After setting well barriers, the VXT is pulled before running drilling BOP allowing the completion to be pulled using a TBIRS.
