Abstract: Disclosed are processes and systems for preventing overpressurization of piping transporting fluid produced from a pressure source to a receiving facility in which the fluid passes through a high integrity pressure protection system (HIPPS). A relief device is provided in the piping in fluid communication with the HIPPS. In the event that fluid passing through the HIPPS during the valve closure time period has a property exceeding an activation property, the relief device is activated thereby allowing the fluid passing through the HIPPS during the valve closure time period to flow to a fluid containment volume. The fluid containment volume has sufficient volume such that upon the start of the closure of the valve in response to the pressure surge, a portion of the fluid passing through the HIPPS during the valve closure time period is absorbed by the fluid containment volume thereby lessening pressure increase in the piping.
