Risk Management provides processes and tools to help organisations minimise the potential for adverse impacts on their stated objectives (eg. profitability, safety, reputation, environment etc…).

We recognise that the central theme of Risk Management is forethought — that is, the early identification and assessment of threats (and opportunities) to these objectives, and then the timely implementation of cost-effective measures to eliminate, prevent or control them.

Risk Management is ultimately a process for creating and sustaining value. We recognise that in the asset-intensive industries such as mining / resources, rail, defence, energy, utilities and telecommunications, there is an inextricable link between the reliability, maintainability and availability of physical assets and plant and the achievement of safety, environmental compliance, profitability and other business objectives.

Industry research has shown that those companies with the best safety performance often display the most consistent profitability in the long term. Why? These companies have usually effected enterprise-wide cultural change and ‘whole-of-life’, holistic, systematic approaches to identifying, assessing and controlling a diverse range of risk types — not just safety.

We believe that the best opportunity to influence plant reliability, maintainability, availability, and ultimately safety, environmental and financial performance, is during the concept, specification and design stages of a project.

Therefore, we offer a range of timely, cost-effective technical risk and reliability engineering services, management consultancies, reviews and training in safety, risk and reliability engineering, including:

· Project Technical Risk Management, System Safety and Reliability Planning,

· Facilitation of hazard identification, risk assessment and control workshops (eg. FMEA / FMECA, HAZOP / CHAZOP, WRAC methodologies),

· System Reliability, Availability and Maintainability (RAMS) analysis,

· Quantitative Risk Analysis (eg. Fault Tree and Event Tree methodologies),

· Functional Safety (AS/IEC61508, AS/IEC61511, AS/IEC62061),

· Machinery Safety (AS4024.1 and ISO12100 / ISO14121 / ISO13849),

· The FAST Functions Allocations Systems Traceability® process,

· Safety Cases, Safety Dossiers & Risk Registers — Compilation, Maintenance, Reviews and Audits, and

· Training in all of the above.
