Pressure-compensated rupture disk assembly for subsea protection of a pressure vessel

摘要

A pressure-compensated rupture disk assembly and method for subsea protection of a pressure vessel. The assembly and method incorporate a piston device, a dynamic piston seal configured to move the piston device when a predetermined pressure is reached; and a rupture disk adjacent the piston device, the rupture disk having a first pressure on a piston side and a second pressure on a second side, the rupture disk being configured to open when a predetermined pressure is exceeded.
