Before the introduction of IEC 61508 and IEC 61511 standards, major chemical companies devised and worked to their own engineering guidelines for the design and implementation of trip and alarm systems.
Inglewood Engineering has worked continuously for a number of these companies since its formation in 1983. Our engineers have lived with the standards as they have evolved and are as familiar as any practitioners with what is required to comply. However, it is important that those engineers who are practising in this field are independently assessed and validated so that customers can have true confidence in their abilities. To this end our personnel seek and have attained the coveted accreditation of TÜV Functional Safety Engineer.
At Inglewood, we are involved with initial hazard analysis, determination of risk reduction, production of the safety requirements specification, defining the safety integrity levels, safety instrumented system design, system reliability calculations and site trip testing.
We regularly audit existing plant alarm and trip systems to ensure compliance with the latest standards.
