Functional Safety

Our customers all share a significant risk of maintaining the license to operate. With increasing automation and systems complexity, government legislation and focus on people and personnel safety managing the risk is critically important. We help our customer to manage their risk by bringing in line with ALARP and SFARP by sharing our knowledge and deep understanding of relevant industry standards such as AS/IEC 61511, AS/NZS 62061, ISO 13849 and AS/NZS 4024.

Process Industry

Functional safety systems in the process Industry, are a separate and independent layer of protection which act once the operations and BPCS have lost control of the process and aim to bring the process to the safe state with high level of dependability to prevent catastrophic event. In process industry the functional safety for safety instrumented systems is governed by IEC61511. The standard recognises that a system dependability is a function of equipment failure rates and the systematic failures caused by human errors during the design process and aims to provide guidance to control these parameters.

We offer the following services in functional safety for process industry.

· Layer of Protection Analysis (LOPA) facilitation

· Safety Instrumented Function (SIF) assessment

· Safety Integrity Level (SIL) Target selection

· Safety Requirement Specification (SRS) Development

· Safety Integrity Level (SIL) verification

· Cause and Effect diagram development

· Safety PLC logic development

· Proof test Requirement development

· Development of Validation test requirements

· Failure Data analysis

· Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) witnessing.

Machinery

Machine safety is regulated by Machinery directive in European union and applies to vast range of powered machinery with one or more moving parts. The legislation sets out the mandatory essential safety requirements to ensure Safety-Related electrical control systems (SRECS) of machines achieve the required degree of systematic risk reduction in hazard associated with operation of machinery. Although, the methods developed in AS/IEC 62061 (i.e., dangerous failure rate per hour) and EN/ISO 13849 (i.e., performance levels) standards are different, but when they are applied correctly and consistently both can achieve a comparable level of risk reduction.

We have the capability to solve the complex issues and offer our help in:

· Machine Hazard Analysis and Risk Assessment

· Safety Integrity Level selection

· Safety Integrity Level verification
