Zusammenfassung:	A SUBSEA PRESSURE CONTROL SYSTEM (44) CAN INCLUDE AT LEAST ONE SUBSEA CHOKE (60) WHICH VARIABLY RESTRICTS FLOW OF DRILLING FLUID (33) FROM A WELL ANNULUS (32) TO A SURFACE LOCATION, THE CHOKE BEING POSITIONED AT A SUBSEA LOCATION, AND A SUBSEA PROCESS CONTROL SYSTEM (74) WHICH AUTOMATICALLY OPERATES THE SUBSEA CHOKE, WHEREBY A DESIRED PRESSURE IS MAINTAINED IN THE WELL ANNULUS. ANOTHER SUBSEA PRESSURE CONTROL SYSTEM CAN INCLUDE AT LEAST ONE SUBSEA CHOKE WHICH VARIABLY RESTRICTS FLOW OF DRILLING FLUID FROM A WELL ANNULUS TO A SURFACE LOCATION, THE CHOKE BEING POSITIONED AT A SUBSEA LOCATION, AND A SUBSEA PUMP WHICH PUMPS THE DRILLING FLUID FROM THE SUBSEA LOCATION TO THE SURFACE LOCATION.
