Simplified representation of the safety lifecycle (IEC 61511)

Safety lifecycle services for the process industry in accordance with IEC 61511

The area of functional safety covers much more than just the Installation SIL-certified hardware and software components. It requires expert knowledge, always aware of latest directives and technologies.

Plant operators, PLT protective devices for risk reduction - this includes operators of almost all chemical plants, refineries, distillation and combustion plants - must implement a system for management of functional safety. Operators are obliged to verify sufficient risk reduction.

In addition to the correct hardware and software, applied planning, operating, and change processes are decisive in ensuring that these systems effectively maintain their intended function throughout the complete lifecycle of the plant.

The basis for these processes are:

• Safety Life Cycle (SLC)
• Safety Integrity Level (SIL)

The safety lifecycle reflects the lifecycle of process plants and is divided into separate phases: Risk assessment, specification of the safety requirements, planning, installation and commissioning, operation, change as well as decommissioning. Errors in the early stages of the project can be often only be corrected later at great effort and cost. We systematically prevent errors in all project phases using our standardized engineering guidelines and verification templates.
