HIPPS Systems
HIPPS is a safety system engineered to prevent overpressure in pipelines by rapidly isolating the source using high-integrity instrumentation and shutdown valves.
HIPPS SYSTEMS
High Integrity Pressure Protection System (HIPPS) is a safety-critical, integrated system designed to protect downstream equipment from overpressure in pipelines by isolating the source through rapid and reliable shut-off in upstream and midstream facilities.
TECHNICAL DESCRIPTION
System Components
- Hydraulic Power Unit (HPU)
- Logic solver (SIL-rated PLC) to process signals and execute shutdown logic
- Pressure sensing elements (redundant transmitters) for continuous monitoring of process conditions
- Final elements (fast-acting shutdown valves) to isolate the source of overpressure
- Hydraulic or pneumatic actuator for reliable valve operation
- Partial stroke testing system for online verification of valve functionality
- Bypass and isolation valves for maintenance and testing
- Control and instrumentation panels for system operation, diagnostics and communication
Key Functional Highlights
- Designed to meet functional safety requirements (SIL 2 / SIL 3)
- Provides an independent protection layer for overpressure scenarios
- Ensures rapid and reliable isolation of upstream sources
- Incorporates redundancy (e.g., voting logic) to enhance system availability
- Allows periodic testing without interrupting process operation
Application Areas
- High-pressure gas pipelines and transmission systems
- Offshore platforms and subsea systems
- Gas processing and compression facilities
- Upstream production and wellhead systems
