Abstract
A subsea assembly can include a pressure control device having an annular seal configured to seal off an annulus formed between an outer housing and a tubular string, a connector, and a guide configured to guide the tubular string into an internal flow passage extending through the subsea assembly, the pressure control device being connected between the connector and the guide. A method can include assembling a subsea assembly with a pressure control device and a connector, the pressure control device including an outer housing and an annular seal, lowering the subsea assembly through water from a rig to a subsea wellhead installation, connecting the subsea assembly to the subsea wellhead installation, and positioning a tubular string in the subsea assembly, so that the annular seal seals against an external surface of the tubular string, the tubular string being exposed to the water between the rig and the subsea assembly.
