HIPPS-High Integrity Pressure Protection
Overview
As oil and gas resources become harder to find, producers are forced to operate in environments of ever increasing severity and risk. Often operating in High Temperature High Pressure (HTHP) applications, the consequences of a catastrophic failure to personnel, the environment and infrastructure are immense.
To help manage the increasing and unprecedented risk, the concepts of Safety Instrumented Systems (SIS) and Safety Integrity Levels (SIL) were created and applied. One such SIS type, is the High Integrity Pressure Protection System (HIPPS). A HIPPS is an independently instrumented protective device, and acts as the last line of defense for protecting downstream operations from over pressurization.
Typically certified to SIL3, a HIPPS gives operators the most dependable pressure protection device available in the market today.

System Components
Mainline Valve
Typically will be trunnion mounted, double block bleed ball type due to proven tight shutoff, high reliability and low operating torque requirements. Ultimately the final valve selection will be based on application specifications and end user preference.
Valve Actuator
Spring-return scotch-yoke or linear piston designs reflecting Paladon Systems’ over thirty years experience with providing valve automation solutions for the most demanding applications in the Oil & Gas industry.
Valve Actuator Control System
Custom systems available for any HIPPS applications. Manifold designs to maximize robustness and reliability.
Logic Solver
Working with our Sira/CASS certified technology partner, we provide TUV/AK6 certified logic solvers. Our logic solvers use standard, proven and function block software which allows for numerous options such as partial stroke testing, and valve function logging to support preventative maintenance programs. Communications to all major DCS systems and customized third party communications interfaces are also available.
The SIS controller can be provided up to a range of IEC 61508 SIL3 platforms to include scalable 2oo3 pressure transmitters and 1oo2 solenoid valve packages. The final SIS choice is dictated by functionality and availability requirements, system costs and client
preferences.
All systems are independently third party certified to ensure compliance with all current legislation and industry standards.
