LNG projects bring together complex process hazards, dozens of OEM packages, safety and control systems, and critical infrastructure cybersecurity requirements. When these pieces are engineered in silos, gaps can create project delays, unnecessary cost, operational problems, and security exposure.
exida helps you bring those pieces together under one integrated lifecycle —so safety, security, schedule, and production goals don't compete with one another.
INDUSTRY SOLUTIONS: LIQUEFIED NATURAL GAS (LNG)
An LNG facility brings together cryogenic processes, volatile hydrocarbons, packaged equipment, and complex control and safety systems. And much of that equipment comes from different OEMs—each with its own engineering practices, documentation, and assumptions.
When safety, alarm management, and cybersecurity are handled separately, the gaps often appear at the interfaces:
The result isn't just engineering complexity. It's risk, cost, delay, and uncertainty.
KEY OPERATIONAL & ENGINEERING CHALLENGES
Building and operating an LNG facility means addressing complex process hazards (cryogenic conditions and volatile hydrocarbons), satisfying strict regulatory requirements, seamlessly integrating disparate OEM skids from multiple vendors, and maximizing site safety without sacrificing overall plant operability or production efficiency.
Every OEM brings their own equipment, documentation, assumptions, and engineering practices.
Safety, control, alarms, and cybersecurity have to work together.
Engineering disconnects discovered during commissioning become expensive changes and schedule delays.
Poor decisions made during design can create nuisance trips, alarm floods, difficult proof testing, and maintenance constraints.
The facility must continue to manage safety and cybersecurity throughout a 30+ year lifecycle.
Keys to Successful Safety Engineering
Reference Asset
LNG facilities bring together complex processes, specialized equipment, and multiple technology providers. Learn how to establish a consistent Safety Instrumented System (SIS) philosophy across packaged equipment and the entire facility—using practical Safety Instrumented Function (SIF) examples to address key project and design challenges.
The exida approach
exida helps LNG owners and EPCs establish a common safety and security framework before engineering decisions become difficult and expensive to change.
We bring together functional safety engineering, alarm management, OT cybersecurity, engineering software, and independent assessment—so the requirements established in FEED carry consistently through OEM packages, commissioning, startup, and operation.
Set the standard -> Coordinate the engineering -> Maintain the result
Functional Safety Management
Establishing an early Functional Safety Management Plan (FSMP) and standardized Safety Requirements Specifications (SRS) during Front-End Engineering Design (FEED), aligns third-party technology providers to a single, consistent design playbook. This prevents interface disconnects, project delays, and unmitigated risk exposure.
SAFETY ENGINEERING TOOL
Standardize project calculations across all EPC and OEM packages using the exSILentia Safety Lifecycle platform — a single source-of-truth for PHA, LOPA, SIL Selection, SIL Verification, SRS Creation, and Proof Test Generation. Leveraging the world’s most comprehensive safety device reliability database (embedded) enables accurate SIL calculations, selection of sensors and final elements, and architecture (redundancy).
INDEPENDENT CONSULTING
Partner with our functional safety experts to lead PHAs, LOPAs, Alarm Rationalization, and SIL Verification. We help you perform safety system design tradeoffs so you can set mission time, proof test intervals, and repair / refurbishment schedules to minimize impact on operations & maintenance.
CYBERSECURITY
Our cyber experts can perform Threat Modeling, High-Level and Detailed Level Risk Assessments per IEC 62443-3-2. We can ensure defense-in-depth network segmentation between control systems and automated safeguards to prevent compromise. Installed solution certification can be applied to previously installed control and safety systems (e.g., critical terminal automation).
SIS PERFORMANCE
The SILstat module helps you to track testing, maintenance, and demands on your Safety Instrumented Functions (SIF). This ensures that you are maintaining your safety system so that it delivers the expected level of risk reduction.
INDEPENDENT AUDITS
Our experts can review and validate the work of others to ensure creation of clear and accurate deliverables that prevent implementation mistakes. We can also perform Functional Safety Assessments (FSAs) as defined in IEC 61511.
An FSA3 (also known as a Pre-Startup Safety Review) must be completed before startup and FSA4 (gathering field data) should be conducted after 5 years of operation.
BENEFITS OF WORKING WITH EXIDA
Establish common safety requirements and engineering practices early so OEM packages and EPC workstreams remain aligned.
Use rigorous SIL analysis and field-verified failure data to avoid both under-designed safeguards and unnecessarily expensive over-design.
Integrate alarm management, safety engineering, and maintenance planning to prrevent alarm floods, reduce nuisance alarms, trips, and disruptive testing.
Maintain the connection between engineering decisions, field performance, testing, maintenance, and cybersecurity throughout the facility's operating life.
exSILentia uses advanced Markov modeling and field-verified failure data to help determine whether safety loops achieve their required risk reduction—without unnecessary hardware, complexity, or cost.
Proof-test strategies shouldn't be an afterthought. exida helps teams plan for testing, maintenance, and turnaround schedule during engineering—so the safety system can be maintained without disrupting production.

Explore exida's whitepapers, technical blogs, and recorded webinars focused on LNG process hazards, OT cybersecurity, and alarm management.
LNG facilities combine specialized process units, packaged equipment, and multiple technology providers. Learn how to establish a consistent SIS philosophy across the facility and address the design challenges created at system and vendor interfaces.
SIS performance depends on assumptions about failure rates, demand rates, proof-test intervals, and mission time. Learn how to compare those assumptions with real-world operating experience and confirm that your safety systems deliver the expected risk reduction.
Cybersecurity requirements can be complex, but your approach doesn't have to be. Learn how asset owners can apply IEC 62443 pragmatically to protect OT environments while managing cybersecurity risk and operational priorities.
Your SIS was designed around assumptions about performance. Learn how to compare those assumptions with actual operating data, evaluate whether the results are statistically meaningful, and make better-informed safety decisions.
Safe Operating Limit exceedances can provide an early warning of process safety problems. Learn how to establish meaningful limits, track exceedances, and use the resulting information to strengthen process safety performance.
Cyberattacks can compromise multiple layers of protection through a single point of entry. Learn how to identify common vulnerabilities and strengthen the independence of safety-critical systems against cyber threats.
A comprehensive Functional Safety Management Plan helps align responsibilities, methods, documentation, and lifecycle activities from hazard analysis through operation. Learn how early planning can help prevent costly gaps, rework, and lifecycle problems.
From FEED through decades of operation, exida can help you identify the risks, establish the right safety and security requirements, coordinate your engineering teams, and build a lifecycle that delivers the performance you expect.
