“…The risk model used in the RB takes into account the status of most critical barriers, whose performance has a significant impact on risk. The information related to the status of these barriers is collected by a set of indicators [26]. The RB method consists of seven main steps [15]:…”

Dynamic risk analysis (DRA) is a novel industrial approach that aims to capture changes in operational conditions over time and quantify their effect on risk. This aspect may be advantageous for providing insight into the causal factors that have substantial risk contributions and supporting decisions related to risk control. Some DRA methods were developed by the oil and gas industry to support the integration of work processes and the cooperation across virtual clusters, e.g., between offshore and onshore systems and/or oil company and supplier. However, DRA has not been extensively adopted and limited attention is given to its validity in practical applications. The objective of this article is to illustrate how this validity can be established based on common validation approaches for risk analysis. The case study focuses on a DRA method named risk barometer that was developed to support integrated operations across the oil and gas industrial systems. The outcome of this study may serve as a basis for the validation of other DRA methods, the use of DRA in practical cases, and ultimately the achievement of integrated operations (IO) capabilities.

“…This method, named TEC2O (Frequency modification methodology based on TEChnical Operational and Organizational factors) is based on periodic revision and updates of indicators whose contribution can modify the expected leak frequency [9]. Indicators are quantitative parameters that can be monitored, modified, and updated over time [31]. The authors developed the method to assess risk in a dynamic way and validated it by means of a benchmark with similar approaches, such as API 581 [13], ARAMIS Project [1], and CCPS [32].…”

In the Oil and Gas sector, risk assessment and management have always been critical due to the possibility of significant accidents associated with the presence of large amounts of flammable hydrocarbons. Methods to provide accurate and reliable risk analysis for an oil platform usually focus on critical equipment and identify causes and consequences of loss of containment. Safety barriers are important elements of such accident scenarios, aiming to reduce the frequency of unwanted events. Estimating the performance of safety barriers is essential for the prevention of major accidents. This work first focuses on the application of risk-based analysis on the process area equipment of the floating platform Goliat. Such an approach is secondly extended to the most relevant safety systems to prevent fires and explosions and consequent catastrophic domino effects. An additional challenge resides in the fact that safety barriers cannot always be classified as equipment, as they are often composed of operational and organizational elements. Through the application of the ARAMIS Project (Accidental Risk Assessment Methodology for Industries in the Context of the Seveso II Directive) results, the frequency modification methodology based on TEC2O (TEChnical Operational and Organizational factors) and the REWI (Resilience-based Early Warning Indicators) method, it is possible to quantify the safety barrier performance, to reduce the frequency of unwanted events. While conducting this study, the importance of the management factor in combination with technical and technological aspects of safety barrier performance was analyzed. Starting from the initial project conditions, applying worsening technical factors, and simulating n organizational management for the safety systems, it is possible to quantify the performance of the safety barriers, highlighting the importance of management factors in terms of prevention of major accidents, and to assess the dynamic risk for the overall plant.

“…Tools providing real time monitoring of safety have also been proposed, as an example Kanes et al [24], based on pre-identified risk factors and process safety related data, quantified increases in risk level in oil and gas industry by using Bayesian Networks. Dynamic risk assessment techniques based on proactive indicators, such as those suggested by Paltrinieri et al [25], Scarponi et al [26], Scarponi and Paltrinieri [27], can bring additional benefits, since risk analysis is supplemented by information related to early warnings of unwanted events. The integration of a set of collected indicators may provide risk assessment with dynamic and proactive features.…”

“…Data collection and processing, for the purpose of DRA, take advantage of information technology. Paltrinieri et al [25] classified dynamic risk assessment techniques based on proactive indicators in four levels by referring to the basic theory and provided results. The first level concerns the use of safety indicators and takes into account the effect of technical, human, and organization factors.…”

The oil and gas sector is one of the most dangerous and stringent workplaces, due to the hazardousness of materials involved as well as the critical tasks that workers have to perform. Cranes are widely used in this sector for several activities. A wrong load lifting or handling often is due to a limited visibility of working area and could bring to severe accidental scenarios, for this reason safety of these operations becomes of paramount importance. The use of safety devices, that provide an augmented vision to the crane-operator, is essential to avoid potential accidents, moreover risk analysis could benefit from the acquisition of real time information about the process. This work aims to extrapolate and adapt dynamic risk assessment concepts for crane-related operations of a typical oil and gas industry by means of the support of safety devices. To achieve this objective, a set of risk indicators, reporting continuous information about the operations that are carried out, will be defined; successively, a technique of aggregation of these indicators will also be applied with the aim to update the frequency of critical events by a proper Risk Metric Reduction Factor that accounts for the effect of the use of safety barriers.
