Functional Safety Assystem Energy and Nuclear has extensive experience in the design and substantiation of safety instrumented systems and are familiar with the requirements of IEC61508 and IEC61511. A number of our engineers have undergone training in customer specific standards such as Sellafield Sites Ltd engineering guide for safety systems, EG90, and have also successfully completed other customer specific but broadly applicable training in the realisation and documentation of safety systems.

Our engineers are experienced in the use of a wide variety of tools and applications for the design and development of software and hardware systems. We have a number of engineers with extensive experience in the development of PLC systems, under IEC61131 and various customer specific standards for a variety of PLC platforms, including Rockwell / Allen Bradley SLC series and Siemens S7. We also have experience with older systems such as Allen Bradley Modicon and PLCZ, giving us the capability to reverse engineer legacy systems in order to upgrade or replace them. ‘Reliability Workbench’ with ‘Fault Tree Plus’ are used for the design and validation of safety systems, several of our engineers are trained and experienced in its use. Rapid development of test systems and less critical control systems is undertaken using National Instruments LabView for which we have a full development environment with many of the popular control and instrumentation sub-packages. Our engineers are experienced with the use of real-time operating environments such as VxWorks and RTLinux and their application in the realisation of embedded real-time systems. Modelling and simulation can be undertaken using Matlab and Simulink for design from early concept through to final system validation. Designs and drawings are produced using AutoCAD and AutoCAD Electrical which allows us to use a component based approach to the creation of schematic diagrams and panel designs. Amtech is used for undertaking and checking cable calculations. All of our engineers are accustomed to the use of various proprietary and bespoke packages as necessary, to satisfy the requirements of specific projects. These include design tools, software development systems and modelling packages.
