The Highest Standard in Operational Analysis

IDEAS HAZOP combines high fidelity dynamic simulation with automated test algorithms to give you a complete picture of how a plant will perform under all possible operating conditions, months or years before commissioning. From checking interlocks to verifying equipment sizing, this tool takes the guesswork out of evaluating whether a design will be safe, practical, and profitable.

Scenario Scores Are Compared To Bring Attention To Most Critical Cases


  • Evaluate plant design and control philosophy performance long before construction
  • Determine the effect of a wide range of  plant upsets:
    • Production rate change
    • Feed rate/grade  change
    • Trip of each individual motor
    • Failure of each instrument, valve, and actuator
    • Mechanical failure of each piece of equipment
  • Comparative scoring and complete dynamic trending for each scenario
  • Scenario execution by software, requiring no human supervision
  • Easy retesting after design changes
  • Detailed reporting, with algorithms to highlight scenarios needing review

Comprehensive Testing

Software-driven testing evaluates a complete set of plant upsets, enabling your engineering team with detailed trends of the plant response under a wide range of operating and upset conditions. Test scenarios are generated and executed automatically based on user-defined rules that rigorously analyze the failure consequence of every piece of the plant.

IDEAS HAZOP was born from our experience supporting the operational analysis of capital projects. In a traditional HAZOP, the determination of what will happen when each piece of equipment fails is a discussion, rather than a rigorous engineering evaluation. Instead of hypothesizing about what will happen in each scenario, we provide a report that contains trends of what happens to key variables in each case.

Industry-Best Simulation Technology

The core of trustworthy analysis is dependable models. IDEAS contains the best available physical models of each piece of equipment, creating a package that accurately represents the chemical reactions, thermodynamics, fluid mechanics, and material transport which make up the plant. The models are all constructed using normal engineering dimensions, such as pump curves, pipe diameters, and tank volumes. Our models have been verified repeatedly over 25 years in a wide range of applications.

Full Control Strategy Analysis

We model the complete control strategy, using logic libraries that mimic control system behavior. The result is a virtual plant that can represent complex interactions between process transients and interlocks across an entire plant area.

Dynamic Process Scoring

A powerful scoring system is the basis for comparing whether each scenario requires further review. The first layer of scoring is assigning costs for materials and energy used, while assigning revenue for the creation of good quality product. Scenarios with more profit are ranked more highly. Then, we add penalties for events that have real-world consequences, such as overflowing tanks or overtemperature events that damage the brick in a kiln.

Scenarios are compared multiple ways to identify events that may need design modifications. Low-scoring cases are indicative of problems. We also identify which are the most common penalties applied by the scoring system as, if there is a consequence that can be caused by many different scenarios, it is typically a good candidate for an engineering change, such as increasing the volume of a surge tank to prevent frequent overflow.

A continuous historian monitors key process indicators for each scenario, which goes into the detailed diagnostic report for each scenario. Problem scenarios are flagged automatically and issued for detailed review.
