Safety Instrumented System Solutions for Process Risk Reduction

Fairtex delivers Safety Instrumented System (SIS) solutions designed to protect personnel, industrial assets, production facilities, and the environment from hazardous process conditions. Our systems are engineered to detect abnormal operating events and initiate predefined safety actions that reduce operational risk and maintain process integrity across critical industrial environments.

We provide complete functional safety engineering services covering system design, SIL assessment, integration, testing, commissioning, lifecycle management, and long-term support. Fairtex combines automation engineering expertise with internationally recognized functional safety practices to deliver reliable and compliance-driven safety systems for offshore, onshore, process, and utility facilities.

Typical applications: Oil and gas processing facilities, offshore production platforms, gas compression stations, tank farms, pipelines, utility infrastructure, process plants, terminal operations, hazardous area facilities, and critical industrial installations requiring automated safety shutdown and hazard detection systems.

What this service covers

Safety Instrumented System Engineering

Fairtex designs and implements SIS architectures that integrate sensors, logic solvers, communication interfaces, and final control elements to perform critical safety functions. Our solutions are developed to meet required Safety Integrity Levels (SIL) and align with operational risk management objectives.

Emergency Shutdown (ESD) & HIPPS Solutions

We provide engineered Emergency Shutdown Systems (ESD) and High Integrity Pressure Protection Systems (HIPPS) that support rapid isolation, process shutdown, overpressure protection, and hazard containment during abnormal operating conditions. These systems are configured to improve operational safety while minimizing equipment exposure and escalation risks.

Fire & Gas Detection Systems

Our Fire and Gas (F&G) systems provide continuous monitoring for combustible gases, toxic gases, smoke, flame, and fire conditions across critical operating environments. Fairtex integrates detection systems with alarm management, shutdown logic, and facility response systems to improve hazard visibility and emergency response coordination.

SIL Verification & Reliability Studies

Fairtex performs SIL verification, reliability analysis, availability assessments, and functional safety studies to validate that safety systems can achieve required risk reduction targets. These evaluations support compliance, operational reliability, and long-term system performance.

FAT, SAT & Lifecycle Support

We conduct Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), loop testing, commissioning, and performance validation to ensure all systems operate according to project specifications and functional safety requirements. Fairtex also supports ongoing lifecycle management, maintenance planning, and compliance documentation throughout the operational life of the system.
