Tailings risk assessment methods comparison

In order to develop a Tailings risk assessment methods comparison we will start by: reviewing a number of existing alternatives to ORE2_Tailings™. This leads to justify the need for the ORE2_Tailings™ approach, discussing what we call the Blackbox objection, which actually applies to all the alternatives and finally the ORE2_Tailings™ procedure, algorithm and results. Alternatives to ORE2_Tailings™ We have grouped possible alternatives into four families discussed below. FMEA FMEA is not a quantitative risk assessment even if it uses indices…

A risky mission

We undertake a risky mission today. That is to reply to information requests we have received from various interested readers in a very concise manner. The risks of the mission mostly arise from: the wide breath of the requests: “please let us know where we could learn about Riskope tailings management activities and methodologies” and the necessity to select among the vast available documentation. A classic preliminary reply We generally start our reply by inviting interested readers to visit Riskope’s…

Hunger stones refresh our short memory

Hunger stones refresh our short memory, they are indeed messages straight from the past. Those who endured droughts and resulting famine left them for their successors. Indeed, the hunger stones tell stories of severe hardship due to droughts. Of course they become visible when it is too late, as they are normally lying below water level (Hungersteine in the Rhine – Memory of great need – Experience Worms (worms-erleben.de). Today we will discuss if these events actually constitute divergence from…

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…

Tailings dams risk mitigation through risk informed decision making

Tailings dams risk mitigation through risk informed decision making (Tailings Dam Risk Mitigation Through Risk Informed Decision Making,) is the title of our PLANNING FOR CLOSURE 2022 paper.   Risk Informed Decision Making (RIDM) supports rational and sensible risk mitigation This blogpost shows how Risk Informed Decision Making (RIDM) using ORE2_Tailings™ supports rational and sensible risk mitigation selection. This is a requirement of the Global Industry Standard on Tailings Management (GISTM). We use an anonymized case report to preserve confidentiality.…

Zero to 300 in thirty

Zero to 300 in thirty is not the performance of a new sensational sport car. And we are talking about thirty years, not seconds! Actually, zero to 300 in thirty years is the cumulative experience Riskope and its founders have dealing with tailings dams risk assessments all over the world.  You should not understand it as an “average” evaluation either, as the evolution has been trending towards exponential. Let’s discover together what we are talking about. Zero to 300 in…
