Questions on ALARP studies at Tailings 2022

 Readers and conference delegates asked the following Questions on ALARP studies at Tailings 2022 and when they read a case study on ALARP optimization. National regulation compliance Are the results of an ALARP analysis consistent with national regulations and design requirements?  When we perform an ALARP analysis we consider local regulations. These will drive some a priori mitigative selections by the engineer of record. These bear on the nature and aim of mitigation stages  for the ALARP analysis. For instance,…

A Case Study on ALARP Optimization

A Case Study on ALARP Optimization is the title our paper at Tailings 2022. The combination of probability of failure and consequences generates the potential risks of dams and other structures. Designers and owners should design, mitigate and monitor throughout the life and toward closure of dams. The GISTM indicates an ALARP objective for mitigation. In the paper we use an anonymized case to show how a dam’s probability of failure and risks evolve with its raising. In a second…

Reading the ICMM Guidance and Conformance protocols

We started reading the ICMM Guidance and Conformance protocols with great interest and were pleased with a number of specifications we saw. Of course, an endeavor of this magnitude and scope will stir a lot of interest in the mining world. From our end, given our long experience in tailings system risks, we could not resist to compare the protocols to our day-to-day practice. We noted areas where more detailed explanations would likely benefit the mining industry and the public.…

Risk tolerance thresholds

Everyone has a different pain threshold and likewise, everyone has different risk tolerance thresholds. We use the plural because each one of us has various thresholds, for example, a perceived one and a financial one. Your risk and risk tolerance thresholds made simple Anyone of us, every-day decides to undertake some activities and consciously or unconsciously assumes risks we consider acceptable/tolerable or sometimes intolerable.Think about various activities: Hunting, fishing, driving a heavy vehicle, and finally cooking in one’s house. They…

geohazards probabilities frequencies and insurance denial

Geohazards probabilities frequencies and insurance denial In the anthropocene insurers are facing “new” challenges when insuring against Geohazards. That is true especially for those caused by Human activity. Indeed geohazards probabilities, frequencies and insurance denial constitute a bundle. Insurers have realized that, because of the dynamic evolution, the usual actuarial point of view faces significant challenges and can be misleading. The indiscriminate use of Force Majeure and Insurance denial to protect themselves is actually detrimental to their business and their…

Force Majeure clauses in contracts should be optimized to reduce costs and litigation potential.

We will discuss today why Force Majeure clauses in contracts should be optimized to reduce costs and litigation potential. Force Majeure clauses in contracts should be optimized to reduce costs and litigation potential. Indeed, any time spent in the aftermath of a mishap “discussing” if the event was Force Majeure, negligence or had other causes severely impacts operations. In addition it can significantly increase the costs of consequences. Thus the need to optimize the Force Majeure formulation. If it was…
