Computational Fluid Dynamics (CFD) is the computational software simulation of fluid-flow phenomena. It uses applied mathematics, physics, and numerical analysis to generate 3D models that can help visual the flow of gas or liquid. aeSolutions uses CFD for modeling to determine consequences of an accidental release for facility siting or hazard scenarios. It is also used for gas detection sensor placement as an alternative method to the Graphical Approach that justifies a more accurate number and placement of combustible and toxic gas detectors.

Periodic test performed to detect dangerous hidden failures in a system so that, if necessary, a repair can restore the system to an ""as good as new condition"", or as close as practical to this condition. The goal of a proof test of a SIF is to reveal previously undiagnosed dangerous hardware failures (those failures that would prevent the SIF from reacting to a hazard). Proof test coverage (the fraction of these failures a given proof can reveal) and the interval at which proof tests are conducted are important inputs into determining if a SIF meets its required SIL. Developing a proof test philosophy can provide for consistency in proof test procedures and how they are conducted. aeSolutions' experts have the field experience to discuss the testing requirements, site practices and available technologies to determine and document a comprehensive testing philosophy. We also have a library of proven proof test procedures to choose from when assembling a testing package, and we have the expertise to work with clients to implement effective testing, failure classification, and feedback mechanisms to validate reliability data claimed in Risk Analysis and SIL Verification.

Approving the Configurations Simulation and Factory Acceptance Testing Approving the Configurations aeSolutions builds process simulation test beds to prove that controls and operator interfaces will function in accordance with project requirements. A FAT plan with checklists lets the client's representatives test every loop and HMI screen against the software design specifications. Quality of workmanship can be reviewed. Punch list items are resolved before shipping the system. aeSolutions offers multiple options for FAT simulation: Option 1. Simulation panels hardwired to the real system I/O cards to emulate field devices. Option 2. Simulation logic configured in the real controllers while ignoring real I/O racks. Option 3. Simulation computers that interface to the real controller's I/O bus in place of the real I/O racks Option 4. Simulation platforms that emulate the real controllers and I/O (for testing logic configurations without controller hardware). Automation Services Previous Next
