Reliability, availability and maintainability modelling
Optimising spares with RAM simulation
Beyond availability to optimising spares, labour and tools.
The price of (single point) failure
Root causes of the two Boeing 737 MAX aircraft crashes, which killed 346.
A modern introduction to Reliability-Centred Maintenance
RCM is the process of determining the most effective maintenance approach, such that the function of the equipment is preserved, with the required reliability and availability at the lowest cost.
EMIT optimisation – getting more out of existing equipment for less
A key challenge facing operators is to optimise their preventive maintenance regimes such that the safety of the plant is maintained, the availability of the plant is maximised and disruptive corrective maintenance or replacement of equipment is minimised.
Improving equipment reliability through smart asset management
Of all the factors with the potential to adversely affect safety and optimal commercial performance of an asset, poor equipment reliability is recognised as one of the most significant.
The power of RAM modelling: optimising facility performance throughout life
Projects in the energy industry often involve the design and build of complex facilities, necessitating upfront capital investment and ongoing operational expenditure. Decisions made during design can carry considerable risk, both in terms of future profitability as well as the impact that incidents may have on health, safety and the environment.
An introduction to safety-critical software
Software is often used to implement the functionality of safety systems because it can be designed to handle complex functionality, is accurate and repeatable, and can be cheaper than hardware solutions. However, there are many examples of safety systems which have failed due to software related faults.
Functional safety: a proportional approach to legacy safety systems
The requirement for identification, specification and maintenance of Safety Instrumented Systems (SIS) is contained throughout legislation, with the industry-wide good practice standard being IEC 61508, Functional safety of electrical/ electronic/ programmable electronic safety related systems. SIS are specific electrical or electronic systems that prevent or mitigate the effect of a hazard.
Closing the safety gap – safety integrity level selection using LOPA
Safety instrumented systems are often used to reduce the risk associated with a potentially hazardous process or plant. It is usual to express the level of risk reduction required as a safety integrity level or 'SIL'. As such, selecting an appropriate SIL is a fundamental step in any safety specification and there are a number of different methods employed, depending on industry.
