TECHNICAL DESCRIPTION

HIPPS package typically consists of:

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

Installations with constraints on flaring or relief discharge
