I&E Systems is one of Australia's leading instrument, electrical and safety system engineering companies. Based in Perth, Western Australia we are 100% Australian owned and have been operating for over 20 years.

Reassessing Failure Rates

Failure probability calculations are based on the assumption that failure rates are fixed and constant. That assumption is completely invalid, but the calculations are still useful.

Automation in Construction

System information modelling in practice: Analysis of tender documentation quality in a mining mega-project

Calculating Risk Reduction

In a safety instrumented system how should we calculate risk reduction for a set of safety functions that shares a common final element?

Avoiding Hazardous Areas by Design

The extent of the hazardous areas should be reduced as far as practicable by applying principles of safety-by-design.

Functional Safety – The Next Edition of IEC61511

What can we expect to see in the new revised edition of IEC 61511?

Duty of Care

The main driver for functional safety is the need to demonstrate duty of care in managing risks.

Competence for Functional Safety

How can we make better use of competency based assessment in functional safety?

Functional Safety Management

Managing the risk of systematic failures is not difficult; the principles are essentially the same as in quality management and risk management.

Lessons Learnt from FSA

Independent audits and assessments reveal the commonly recurring and widespread problems.

Towards Systematic Integrity

This paper is on the topic of avoiding errors and failures due to the design, implementation and operation of the systems.

Achieving Compliance in Hardware Fault Tolerance(Updated Nov.2016)

Many users in the process sector have not been able to comply fully with the requirements for hardware fault tolerance – but there are practical ways of achieving compliance.

Derivation of the Simplified Equations

Even the ‘simplified’ equations for probability of failure can seem to be a bit mysterious. Here is an explanation in plain language.

Assessing the impact of RFIs in Electrical and Instrumentation
Engineering Contracts – Research Paper

The cost of managing RFIs in todays complex E&I projects is much higher then generally expected.
