During the first couple decades of our professional life we worked extensively with Landslides risk assessment and monitoring in the European Alps. Most sites were in Switzerland and Italy. At the beginning “risk” was not yet the buzz-word it became later. Clients and governments were seeing hazards impinging on population and infrastructure like transportation, hydropower and bulk-storage facilities. Engineering “repairs” were the most obvious path. Nevertheless, back in 1997 Riskope’s founder Franco Oboni participated in a IUGS workshop in Honolulu. The…Read More
We are very pleased to see the notion of societal risk acceptability in the Canadian House of Commons, emerge publicly through the records. It is indeed a rare occurrence that information on our work is made public, due to the strict NDAs we sign with our clients. Actually, Mr. Chris Apps, Director, Lands and Resources at Kitselas First Nation, reported on Riskope’s work (see the section at 1655 in the record). Our findings were used to bring positive changes to…Read More
Multi dimensional Consequences approaches take into consideration the varied losses that a failure can generate. Thus they allow for a more thorough and rational evaluation of a failure potential consequences. Indeed, by breaking down the consequences into distinct dimensions, such as environmental, economic, and social, an additive evaluation of multi dimensional consequences can provide a more realistic assessment of the risks associated with a failure. This approach also allows for greater consideration of the long-term implications of the failure. These…Read More
A mining company asked us to perform a Prefeasibility hazard adjusted NPV evaluation. Our action first focused on bringing clarity in their risk register which presented numerous classic mistakes. Among these the usual confusion in terminology, confusing risks and hazards, uncertainties vs risks, etc. Once the risk register was corrected it was possible to perform the requested hazard adjusted NPV and to draw valuable conclusions. Among these, we highlighted potential fatal flaws of the project which warranted in depth analyses…Read More
A colleague recently engaged a discussion on ORE2_Tailings and ALARP. He presented various refences on the subject then asked us to check if ORE2_Tailings™ complies with the various definitions. Indeed, we have published on ALARP in recent international conferences: Oboni C., Oboni, F., A Case Study on ALARP Optimization, Tailings 2022, Santiago Chile, May July, 2022 and Oboni F., Oboni C., Optimizing mitigation of tailings dams portfolios, Tailings and Mine Waste 2022, Denver, CO ,November, 2021 (video). We are delighted to report…Read More
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…Read More
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…Read More
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…Read More
