Bridge Structures

In recent years, the use of large scale seismic risk assessment has become increasingly popular to evaluate the fragility of a specific region to an earthquake event, through the convolution of hazard, exposure and vulnerability. These studies tend to focus on the building stock of the region and sometimes neglect the evaluation of the infrastructure, which has great importance when determining the ability of a social group to attend to a disaster and to eventually resume normal activities. This study, developed within the scope of the EU-funded project ITERATE (Improved Tools for Disaster Risk Mitigation in Algeria), focuses on the proposal of an exposure model for bridge structures in Northern Algeria. The proposed model was developed using existing national data surveys, as well as satellite information and field observations. As a result, the location and detailed characterization of a significant share of the Algeria roadway bridge inventory was developed, as well as the definition of a taxonomy that is able to classify the most common structural systems used in Algerian bridge construction. The outcome of this study serves as input to estimate the fragility of the bridge infrastructure inventory and, furthermore, to the overall risk assessment of the Northern Algerian region. Such fragility model will, in turn, enable the evaluation of earthquake scenarios at a regional scale and provide valuable information to decision makers for the implementation of risk mitigation measures.

Credit Risk Assessment

The study is primarily focused on credit risk assessment practices in commercial banks on the basis of their internal efficiency, assessment of assets and borrower. The model of the study is based on the analysis of relationship between credit risk management practices, credit risk mitigation measures and obstacles and loan repayment. Based on a descriptive research approach the study has used survey-based primary data and performed a correlation analysis on them. It discovered that credit risk management practices and credit risk mitigation measures have a positive relationship with loan repayment, while obstacles faced by borrowers have no significant relationship with loan repayment. The study findings can provide good insights to commercial bank managers in analysing their model of credit risk management system, policies and practices, and in establishing a profitable and sustainable model for credit risk assessment, by setting a risk tolerance level and managing credit risks vis-a-vis the prevailing market competition.

Arc Flash

Oil and gas facility managers are well aware that attention to detail saves lives and supports business continuity and reputation. Those tasked with stewardship of electrical assets will be aware of the need to protect their employees from the hazard of electrical arc flash and that it should be at the forefront of safety thinking. Complacency and lack of duty of care with this real and possibly un-quantified hazard can lead to fatalities. The primary solution to arc flash consequences in older installations has been the implementation of safe work procedures and personal protective equipment. While still valid, these solutions are the least effective options in the hierarchy of controls. SKM have developed a practical risk mitigation strategy that considers the hazards of prospective arc flash energy together with the cumulative effect of switchboard age, design, capability and condition. The strategy also considers the range of potential mitigation controls available through the mechanism of substitution and engineering design that focuses on reducing: The likelihood of an arc flash incident occurring; The likelihood of personnel exposure; and, The energy released should an incident occur. A structured arc flash risk assessment process can provide the asset owner the opportunity to rank individual switchboards for likelihood, consequence and risk, and thus provide direction for engineered remediation and capital expenditure. SKM proposes the way in which arc flash risk can be assessed, how appropriate layered mitigation measures might be selected, and how an asset owner may approach the issue of arc flash hazard mitigation to economically and reliably protect its employees.

Abstract The deployment of a deep-diving long-range autonomous underwater vehicle (AUV) is a complex operation that requires the use of a risk-informed decision-making process. Operational risk assessment is heavily dependent on expert subjective judgment. Expert judgments can be elicited either mathematically or behaviorally. During mathematical elicitation experts are kept separate and provide their assessment individually. These are then mathematically combined to create a judgment that represents the group view. The limitation with this approach is that experts do not have the opportunity to discuss different views and thus remove bias from their assessment. In this paper, a Bayesian behavioral approach to estimate and manage AUV operational risk is proposed. At an initial workshop, behavioral aggregation, that is, reaching agreement on the distributions of risks for faults or incidents, is followed by an agreed upon initial estimate of the likelihood of success of the proposed risk mitigation methods. Postexpedition, a second workshop assesses the new data and compares observed to predicted risk, thus updating the prior estimate using Bayes’ rule. This feedback further educates the experts and assesses the actual effectiveness of the mitigation measures. Applying this approach to an AUV campaign in ice-covered waters in the Arctic showed that the maximum error between the predicted and the actual risk was 9% and that the experts’ assessments of the effectiveness of risk mitigation led to a maximum of 24% in risk reduction.

Northern Sea Route

Arctic regions, and thus ice-covered waters, are continuously getting higher in the national and international political agenda. The world demand in energy resources and the need in development of new transportation routes are pushing industrial activities up North where we see prospects and expectations on one side, and gaps and challenges on the other. Industrial development of the new geographic area is complex, and the priority in transportation is given to marine shipping. For the recent years, transit cargo shipping through the North Eastern Passage or the Northern Sea Route (NSR) increased more than 10 times from 0.11 million tons (4 passages) in 2010 to 1.36 million tons (71 passages) in 2013. Although, the numbers are small compared to global cargo shipping, the sensitive Arctic environment requires the establishment of a oil spill recovery system as well as risk mitigation measures. This, in turn, requires the preceding development of a risk assessment methodology for oil spills in ice-covered waters. Therefore, this paper presents the challenges involved in Arctic shipping along the NSR and identifies the knowledge gaps with respect to environmental risk assessment of accidental oil spill.

The Apulian Poison Centre (PC) of Foggia, Italy, annually manages numerous consultations concerning certain or suspected poisonings from pesticides, starting at the same time a careful activity related to the risk assessment phase. The management of the exposure to pesticides and to other chemicals, and the alerting of the “National center for chemicals, cosmetics and consumer protection” at the Istituto Superiore di Sanità (ISS), actively contributes to the improvement of products quality and safety. Thus, leading to a reduction in the number of intoxications - and therefore of the accesses to the emergency services - allows greater protection for workers, bystanders, residents and consumers. The reported case of methomyl poisoning has been of fundamental importance both from the medical point of view and for the management of the intoxicated patient, both for the risk assessment actions, and for cooperation with the competent authorities, generating discussion points on the regulations in force between PCs and National Competent Authority. It follows that the feedback of intoxication in an emergency can lead to improvements in the management and risk mitigation measures in order to reach a greater protection of human, animal, and environmental health. In addition, the regulatory feedback deriving from these reports is an input to the increase product quality improvement (mixtures, labels, packaging, and risk communication) leading to a greater protection of potential exposed subjects. The importance of creating an information and management network that allows the optimization of the flow of information deriving from PCs arises. The actions taken are therefore described, both relating to the management of the emergency, and relating to the subsequent information flow and to the measures for containing the consequent risks.

Harmful Effects

Extreme hydro-meteorological phenomena lead annually to serious damage and losses in the coastal zone of Isla del Carmen, on the Gulf of Mexico. The importance of the risk assessment is the possibility of preventing or reducing those harmful effects. In this context, an integrated risk assessment approach is performed based on the source-pathway-receptor concept to assess the flooding risk in the area. The paper analyses the consequences on the dune ecosystem that extends longitudinally along the island; and the effects on the population, infrastructure and natural habitat located next to the beach. The results of the study will be used to define the zones with a higher level of risk and to propose flood risk mitigation measures. Moreover, the study will contribute to the establishment of specific legislation which supports the protection of the coastal dune.

<p>The Valle d'Aosta Region and the Autonomous Province of Bolzano territories include the highest mountain areas of Italy, where most of the communication infrastructures or strategic activities are totally or in part partially exposed to the rockfall hazards.  </p><p>For this reason, the two administrations have established an operational cooperation in order to compare their procedures and to define the criteria and best practices to prioritize and project the mitigation the rockfall mitigation measures. The result achieved by the work group have inspired a new incoming version of the Italian technical standard UNI 11211 “Rockfall protective measures”.   </p><p>As a part of the rockfall risk assessment of the designing the mitigation measures, it is necessary to assess the actual effectiveness of the alternative mitigation options which have been identified.  </p><p>The choice whether to mitigate the event intensity or the expected damage, with either structural or non-structural measures, will usually achieve a risk mitigation level, associated to a complimentary residual risk. </p><p>Therefore, the project management has to evaluate the degree of hazard and risk mitigation for any given solution. The acceptability of the residual risk and its possible mitigation through organizational measures are to be evaluated as well. A long-term cost/benefit analysis has to be performed, taking also into account the tolerability over time of the handling costs. </p><p>The first milestone in the decisional process the definition of the acceptable risk level. As a matter of fact, which is the key criterion supporting the decision to undertake cost-effective investments in mitigation works. For that reason, a preliminary analysis of the in-situ geological conditions should be as complete and detailed as possible. Project managers have to be aware that the zero-option has to be taken in to account as well, in the case the risk level would not be acceptable. </p><p>Moreover, it has to be taken into account that the risk evaluation is always site-specific, because the rockfall mitigation projects have to be based on a detailed geological reference model. Local changes in geological, hydrogeological, morphological and structural conditions, vegetation, vulnerability and exposure of the objects at risk may lead to different hazard and risk conditions even at a local scale. Therefore, a risk assessment analysis is consistent to a single project and can’t be directly upscaled to implement, for instance, a municipal land management plan.   </p><p>Another key point in the decision-making process is the expected damage assessment, which has to include not only the direct damages (e.g.: loss of human lives) but also the indirect damages and their economic and social impacts. As a consequence, in assessing the acceptable risk both the probability of direct and indirect damage and the economic and social benefits derived from its acceptance have to be weighted. </p><p>The final result has led to guidelines based on QRA (Quantitative Risk Assessment) method and defining three risk levels: Acceptable, ALARP (As Low As Reasonably Practicable) and Unacceptable, providing to the project managers a rational and objective framework to manage rockfall hazards in Italy. </p>

On 18 February 2016, the European Ombudsman delivered a decision (case 12/2013/MDC) that has the potential to thoroughly shake up the manner in which the European Commission authorises plant protection products (PPPs).Pesticide Action Network Europe (PAN-Europe) brought the case before the Ombudsman. It alleged that the Commission approves potentially unsafe PPPs and disregards data gaps in the risk assessment, thereby ignoring concerns raised by the European Food and Safety Authority. PAN-Europe also argued that the Commission fails to set appropriate risk mitigation measures and to check Member States’ compliance with those measures. The Ombudsman largely agreed with PAN-Europe. She found that the Commission indeed authorised substances, even when it was unclear whether a substance met the legal health and environmental safety requirements. The Ombudsman made several recommendations to the Commission for bringing its approval practice, which constitutes maladministration, in conformity with EU pesticide law.

Hierarchy Process

Deciding on the effectiveness of risk reduction measures is a common problem that involves tradeoffs among multiple different and generally qualitative criteria. Often risk mitigation measures implemented for pipeline risk reduction cannot be easily quantified, but it can be ranked. Hence, there is a need to identify which risk reduction measure is the most effective amongst the competing options. This paper uses Analytic Hierarchy Process (AHP) approach to select optimal solutions that best satisfies all of the decision maker’s requirements. This paper presents the development of an AHP model and the derivation of a quality index. The model is used for a hypothetical case study of various remediation works to an existing pipeline. The advantages of using such a technique are also discussed. This proposed model of risk assessment is useful for risk management during the planning and building stages of a new pipeline, as well as for modification and changes of use for an existing pipeline.
