Our Services What Are Tomorrow's Leaders Learning From Us Today? A Lesson in Ethical Leadership Leaders face constant pressure to move fast and hit targets. The risk isn't a single bad decision, it's the small compromises that start to look reasonable. What are tomorrow's leaders learning from watching how we handle that pressure today? Whitepaper: The Courage to Intervene | Developing Ethical Leadership in the Next Generation of Process Safety Professionals As the process industries experience the “great shift change,” developing the next generation of leaders requires more than technical competence. It demands ethical courage and the ability to influence others to uphold process safety under pressure. This paper explores how ethical decision-making and leadership behaviors can be intentionally developed through structured case-based learning derived from real engineering failures. aeSolutions Recognized with 2026 CSIA Social Responsibility Award aeSolutions is proud to share that we were recognized with the 2026 Social Responsibility Award at the 2026 CSIA Awards, held during the Control System Integrators Association Conference in Baltimore, Maryland.

The Risk Reduction Factor (RRF) is the inverse of PFD (RRF = 1/PFD) and is used to establish the associated Safety Integrity Level (SIL) rating required for a Safety Instrumented Function (SIF) to reduce the hazard risk to an acceptable risk tolerance level. Once a Process Hazard Analysis (PHA) has been completed and Independent Protection Layers (IPL) have been applied, any SIF that serves as an IPL must have an established RRF. Over-specification of devices to be used in a SIF is not uncommon because it is a SAFETY Instrumented Function. However, over-specification does not necessarily improve safety significantly and can reduce the resources available for overall safety. aeSolutions can help you identify the best devices to use in SIFs and assist you in the purchasing process.

The graphic model of Fault Tree Analysis (FTA) is a type of failure analysis in which an undesirable condition of a system is explored. By use of Boolean logic, a Fault Tree Diagram shows the logical interrelation of events that, taken apart or together, may lead to a system or device failure.

Supporting Client Successes Maintenance and Support Supporting Client Successes aeSolutions offers qualified specialists to support clients' needs. Personnel can be provided to augment the client's staff or to consult on specific issues (hardware, software, safety, advanced control, networks, and alarm management, to name a few.) A Technical Services Agreement (TSA) is an annual arrangement with a time-plus-expenses purchase order and discounted pricing. The TSA makes pre-designated specialists available for pre-planned work or for short notice call outs. A small annual fee applies. For emergency service calls without a TSA in place, aeSolutions will make every effort to respond, depending on resource availability. • Staff augmentation services • Consulting services • Technical services agreement (TSA) • Emergency service order Automation Services Previous Next

Breakdown maintenance is a reactive maintenance strategy where repairs are only carried out after equipment has failed. This approach is typically used for non-critical assets where downtime does not significantly impact overall operations.
