IEC 61511 Consulting
Ask this service to verify compliance with the IEC 61511 standard of the systems intended to perform safety functions
The use of a reliable safety instrumented system (SIS) passes through the SIL (Safety Integrity Level), which highlights the degree of overall functional safety within complex industrial processes.
For this reason, the consultation for the verification and validation of the SIL level according to the IEC 61511 standard helps you verify that the system provided reaches a suitable SIL level.
Compliance with IEC 61511 sees us directly involved in drafting and supporting your engineering in the following phases:
- Support in component selection from a Functional Safety point of view
- Preparation of the safety plan with contents in accordance with paragraph 5.2.4 of IEC 61511
- Preparation of the SRS document with contents in accordance with paragraph 10 of IEC 61511
- Preparation of the Safety Manual with contents compliant with paragraph 11.2.1 of IEC 61511
- Preparation of functional test plans and reports
- Preparation of a Safety Analysis Report (SAR) in accordance with NOG 070, for evaluating all the main aspects in relation to functional safety
In addition, validation through software application is just as important. Many potential risks to Safety Instrumented Systems relate to the fault management tools, or to diagnostic functions inactivated during programming. The complete diagnosis of the software is included in our consultancy.
The analysis we carry out to support your functional safety is applicable to any system, whatever its size and complexity: from small stand-alone electromechanical systems, to entire systems distributed throughout the field with multi-platform software (e.g. HIPPS, Turbomachinery, Fire & Gas Systems, etc).
Get in touch with us to comply with the functional safety standards.
IEC 61511 Training
Plan your company on-the-job training on functional safety requirements
Knowledge of IEC 61511 requirements is essential for those who use complex systems, to guarantee the safety of people, the environment and the infrastructure itself.
The objective of the training on the IEC 61511 standard is to support the people responsible for the safety systems used in the process industry in acquiring skills for the compliance with the functional safety requirements of the safety systems and on the performance of the systems.
It is possible to organize the training days online or in person according to the needs and the number of participants.
The training program is developed on-the-job, as it conceptually and operationally accompanies company figures who use safety systems that comply with functional safety standards.
The training plan covers the IEC 61511 standard and the applicable functional safety principles for the verification of the SIL level required, with the aim of training personnel through a technical-operational approach.
The training sessions are held by TÜV Rheinland certified teachers,with referenced experience in the field of functional safety, and cover the following modules:
- Functional safety management
- Requirements of the safety lifecycle
- Risk analysis
- Safety Instrumented Functions
- Assignment of SIL
- Probability of failure on demand (PFD)
- Safety Instrumented Systems
- Residual Risk and Tolerable Risk
- Determining of SIL
- Calculation of PFDavg
- Diagnostic coverage (DC)
- Mean time to repair (MTTR)
- Proof Test and Proof Test Interval
- Periodic Partial Tests
- The Safety Manual
- Risk analysis methods PRA, ALARP, HAZOP, LOPA
- Installation, operation and maintenance of the SIS
- FAT and SAT
- Installation and commissioning of the SIS
- Use and operation of the SIS
- Maintenance, modification and disposal of the SIS
The skills acquired can be put to immediate use in your organization, and are certified with the participation certificate.
Get in touch with us to acquire the right skills on functional safety.
