Tolerable risk thresholds

Tolerable risk thresholds, aka risk tolerance are always project and owner-specific. They indicate the level of risk which has been deemed acceptable for a specific project or operation. Furthermore, tolerable risk thresholds and appetite for risk is quite different for various key stakeholders, for instance: Mine owner, Regulatory Bodies, Adjacent Communities, etc.   So how can one manage the sometimes divergent tolerable risk thresholds between stakeholders? Additionally, a topic that comes regularly in the mining world is diverging risk tolerance among…

Convergent Leadership Divergent Exposures

The title of our new book is Convergent Leadership Divergent Exposures. The manuscript was delivered to our publisher on March 1st 2021 and should be published by July 29th 2021. How will Convergent Leadership Divergent Exposures benefit you? Today’s corporate, industrial and government decision makers must address risks and hazards on a scale never before encountered. As a matter of fact, policy makers and managers face complex business-as-usual hazards, black swans and Acts of God that can lead to devastating…

Risk assessment and automation bias

In these days of AI, IoT and other technological developments Risk assessment and automation bias have to be discussed. The definition of Automation bias covers the propensity users have to favor suggestions from automated decision-making systems. Victims of automation bias will ignore contradictory information made without automation, even if it is correct. Automation bias is the last of a long dynasty Automation bias is heir to a dynasty of biases based on the same principle, but seemingly very different one from another,…

Business as usual definition in Risk Assessment

Business as usual definition in risk assessment, as defined in our day-to-day practice, is an unchanging state of affairs. That is, despite the occurrence of non-divergent hazards of any kind (man-made, natural). An example of business as usual and non divergent hazard For instance, the variability of any parameter as considered and specified in the design of a system is “business as usual”. Therefore that variability does not represent a hazard. For example, the variation of the oil price of…

Act of God in probabilistic risk assessment

We define an Act of God in probabilistic risk assessment as an event with a probability of occurrence below the general consensus for credibility. In other words it is an unbelievable event that is supposed to be unfathomable “God’s will”. We can quantify probabilities down to certain frequency levels. As a matter of fact, in our day-to-day practice we consider events probabilities as follows: down to 10-5 as credible, between 10-5 and 10-6 as poorly credible, and finally, below 10-6…

Holistic Geoethical Slopes’ Portfolio Risk Assessment in Geological Society

We are proud to publish Holistic Geoethical Slopes’ Portfolio Risk Assessment in Geological Society, London, Special Publications, 508. We want to personally thank Giuseppe Di Capua of IAPG for inviting us. Here is a summary of what we discuss in our paper Landslides of natural and man-made slopes, including dykes and dams represent hazardous geomorphological processes that generate highly variable risks. To optimize a slope mitigation approach, one has to combine the probability of failure and the cost of consequences…

The impact of standard of care on dams survivability

Using ORE2_Tailings we can quantify the impact of standard of care on dams survivability. In this blogpost we take three dams, namely Dam x, Dam y and Dam z. Their design was identical with initial factor of safety of 1.3. In addition, they had similar QA/QC, construction method, same systemic approach, efforts and uncertainties consideration. Various small mishaps hit the dams along their history. Some repairs occurred, under different contracts, different quality control and finally, at different times. It turns…
