A structured and systematic technique for evaluating potential hazards that put employees and/or equipment at risk in a system. There are four basic stages of a HAZOP analysis: Definition, Preparation, Examination, and Documentation. HAZOP Analysis is based on a theory that assumes risk events are caused by deviations from design or operating intentions. Guide words are used to aid HAZOP analysis execution by determining the scope and objective. Some of these include no/none/not, more, less, before, after, part of, higher, lower, etc. Acronyms & Terms Glossary <- More Definitions HAZOP (Hazard and Operability) Analysis A structured and systematic technique for evaluating potential hazards that put employees and/or equipment at risk in a system.

“Fit for Purpose” Solution Reduces Planned Downtime by 66% aeSolutions’ hybrid safety system design enabled the client to maintain safe continuity of their fired equipment, meet NFPA compliance, and significantly lower planned downtime. Challenge Several challenges related to strict National Fire Protection Association (NFPA) requirements arose as part of our client’s multi-stream waste incinerator’s annual leak testing. Any solutions would include navigating between NFPA-compliant and SIS-based systems and could lead to loss of revenue associated with destabilizing shutdowns, the likelihood of spurious trips, and planned downtime. Solution aeSolutions’ team of engineers and subject matter experts customized a “Fit for Purpose” engineering and equivalent risk-reduction solution that would meet or exceed NFPA codes as well as engaged the Authority Having Jurisdiction (AHJ) for approval of this customized approach. Among other efforts, our experts performed detailed configuration and integration of the client’s new Triconex process safety system with their existing DCS (distributed control system). Results Our approach enabled the client to select a hybrid, compliance/risk-based solution. aeSolutions identified and engaged the AHJ for approval of this customized approach, which proved to: • Implement compliance solutions that encourage system-wide risk reduction • Sustain reliability and availability of equipment to maintain operations • Increase leak test intervals with online testing reducing planned downtime by 66% Learn more about how aeSolutions could help you with a similar Combustion project.

Mechanizing in Real Time Factory Automation Systems Mechanizing in Real Time aeSolutions has delivered automation solutions with Programmable Logic Controllers for nearly two decades. In the 1970's, a PLC was a programmable emulator of relay ladder logic. Today, a PLC is a scaled down controller, often stand alone, but with much of the power and some of the functions of controllers used in DCS process automation. Multiple PLC's are often networked somewhat like a DCS with fewer features. aeSolutions can provide the right PLC automation system when a client needs highly reliable and very fast real time response to events in a manufacturing cell or an electromechanical panel. Ruggedized operator displays and touch screens allow local HMI control. The PLC can also be interfaced to a supervising DCS. • High speed I/O and processing • Ruggedized environment • Basic networking and communications • Ladder logic programming familiar to I&E staff • Scalable in size and cost Automation Services Previous Next
