Lessons learned in twenty years of hazard, risk and resilience analyses

Writing lessons learned in twenty years of hazard, risk and resilience analyses has been a difficult exercise for various reasons. We compiled  and explain lessons learned in our practice of risk assessment and resilience advice to industries, municipalities and regional governments around the world in our latest book, Convergent Leadership – Divergent Exposures: Climate Change, Resilience, Vulnerabilities, and Ethics. However, the fact that we systematically apply our quantitative convergent approach (ORE, Optimum Risk Estimates) to all sorts of industries and…

Sustainability, ethics and risks

Sustainability, ethics and risks results from a discussion we read on LinkedIN. The discussion arose after our friend Giuseppe di Capua cited SUSTAINABLE MINING – WHAT EXACTLY DOES IT MEAN? . The author of that paper is David Ovadia, for the @IAPG blog (https://www.geoethics.org/ ). The core of the discussion These days,  mining projects oftentimes tout their ‘sustainability’. The term reverberates from sources like the UN’s sustainable development goals. David Ovadia wonders if the term sustainable  can be used in mining.…

Tailings dam mitigation risk informed decision making

Tailings dam mitigation risk informed decision making closes the discussion we presented in prior blogposts. We now focus on one dam and show how ORE2_Tailings™ supports rational and sensible risk mitigation decision-making as requested by GISTM. The dam case The dam we selected for this example is inactive and is parallel to a valley bottom. An unprotected creek runs at its toe and the bed is considered to be sufficient for the 1/500 return. Beyond that flood, there will be…

Tactical and strategic planning for dam portfolio using ORE2_Tailings

Tactical and strategic planning for dam portfolio using ORE2_Tailings is the third of a series of blogposts explaining how to use ORE2_Tailings™ results. Indeed it follows: Dam portfolio ORE2_Tailings support for decision makers and ORE2_Tailings supports ICMM global industry standard on tailings management conformance. We use the same figures we have developed in those prior discussions. Summary of the portfolio ORE2_Tailings™ results With respect to probability of failure The portfolio of ten dams is made of two “bad apple” dams…

Dam portfolio ORE2_Tailings support for decision makers

Dam portfolio ORE2_Tailings support for decision makers follows-up on a prior example. We will show how to interpret the graph we present in that prior post. Dams probabilities of failure and ORE2_Tailings benchmarking at portfolio level. The portfolio of ten dams is displayed on the annualized probability of failure graph, together with the world-wide benchmarks. This graph shows dams: AA1 entirely under the benchmark range, AA3 straddling the benchmark range (uncertainty on the worse case pf estimate slightly above benchmark),…

Dam portfolio ORE2_Tailings support for ICMM standard on tailings management.

Dam portfolio ORE2_Tailings support for ICMM standard on tailings management (GISTM) is multifaceted. ORE2_Tailings™ is a risk assessment platform specifically Riskope designed specifically for tailings systems. When we deploy it to a portfolio of dams, possibly over multiple properties, it allows for tactical and strategic planning. We have already discussed the single dam case in relation to ICMM • Global Industry Standard on Tailings Management (2020)  and the conformance protocols. Today we present an example of deployment at portfolio level.…

Risk tolerance for tactical and strategic planning

We discuss risk tolerance for tactical and strategic planning using an excerpt from a case study in our forthcoming book. The title is Convergent Leadership – Divergent Exposures and the case study is in Chapter 16. In the book we include three complete case studies with different level of information and requirement. Setting of the case study covering risk tolerance for tactical and strategic planning Kryptonite corp. has three plants shipping bulk material through a wharf called Terminal reached by railroad…

ORE2_Tailings supports ICMM global industry standard on tailings management conformance

ORE2_Tailings supports ICMM global industry standard on tailings management conformance (GISTM). ORE2_Tailings™ is a risk assessment platform specifically designed for tailings systems created by Riskope.   We recently published the notes we took while reading ICMM guidance and conformance protocols. In that text we stated that ORE2_Tailings™ anticipated the requirements of ICMM GISTM. Indeed, the threads of our publications, which culminated with Tailings Dam Management for the Twenty-First Century shows that evolution. Today we bring to your attention an example…
