Tools, Technologies and Frameworks for Digital Twins in the Oil and Gas Industry: An In-Depth Analysis.

The digital twin (DT), which involves creating a virtual replica of a physical asset or system, has emerged as a transformative set of tools across various industries. In the oil and gas (O&G) industry, the development of DTs represents a significant evolution in how companies manage complex operations, enhance safety, and optimize decision-making processes. Despite these significant advancements, the underlying tools, technologies, and frameworks for developing DTs in O&G applications remain non-standardized and unfamiliar to many O&G practitioners, highlighting the need for a systematic literature review (SLR) on the topic. Thus, this paper offers an SLR of the existing literature on DT development for O&G from 2018 onwards, utilizing Scopus and Web of Science Core Collection. We provide a comprehensive overview of this field, demonstrate how it is evolving, and highlight standard practices and research opportunities in the area. We perform broad classifications of the 98 studies, categorizing the DTs by their development methodologies, implementation objectives, data acquisition, asset digital development, data integration and preprocessing, data analysis and modeling, evaluation and validation, and deployment tools. We also include a bibliometric analysis of the selected papers, highlighting trends and key contributors. Given the increasing number of new DT developments in O&G and the many new technologies available, we hope to provide guidance on the topic and promote knowledge production and growth concerning the development of DTs for O&G.

Extensive pipeline location data resource: Integrating reported incidents, past environmental loadings, and potential geohazards for integrity evaluations in the U.S. Gulf of Mexico.

The U.S. Gulf of Mexico contains a complex network of existing, decommissioned, and abandoned oil and gas pipelines, which are susceptible to a number of stressors in the natural-engineered offshore system including corrosion, environmental hazards, and human error. The age of these structures, coupled with extreme weather events increasing in intensity and occurrence from climate change, have resulted in detrimental environmental and operational impacts such as hydrocarbon release events and pipeline damage. To support the evaluation of pipeline infrastructure integrity for reusability, remediation, and risk prevention, the U.S. Gulf of Mexico Pipeline and Reported Incident Datasets were developed and published. These datasets, in addition to supporting advanced analytics, were constructed to inform regulatory, industry, and research stakeholders. They encompass more than 490 attributes relating to structural information, incident reports, environmental loading statistics, seafloor factors, and potential geohazards, all of which have been spatially, and in some cases temporally matched to more than 89,000 oil and gas pipeline locations. Attributes were acquired or derived from publicly available, credible resources, and were processed using a combination of manual efforts and customized scripts, including big data processing using supercomputing resources. The resulting datasets comprise a spatial geodatabase, tabular files, and metadata. These datasets are publicly available through the Energy Data eXchange®, a curated online data and research library and laboratory developed by the U.S. Department of Energy's National Energy Technology Laboratory. This article describes the contents of the datasets, details the methods involved in processing and curation, and suggests application of the data to inform and mitigate risk associated with offshore pipeline infrastructure in the Gulf of Mexico.

Morbimortality profile by COVID-19 in telework and on-site work in an oil and gas company in Brazil.

BACKGROUND: As a reflection of the health emergency caused by COVID-19, many countries adopted guidelines, which included activity restrictions. As a result, some companies maintained their activities with on-site work and telework. OBJECTIVE: Analyzing the morbidity and mortality profile due to COVID-19 of workers in telework and on-site work in an oil and gas company. METHODS: Cross-sectional, quantitative, and analytical study that included 8,394 workers diagnosed with COVID-19 at an oil and gas company in Brazil, from June 2020 to June 2021. The company's Surveillance Program database was used as an information source. RESULTS: The total prevalence of cases was 21.7%. For teleworking and face-to-face workers, they were 20.7% and 23.3%, respectively. There was a predominance of women (19.7%), white ethnicity/colour (64.7%), higher level position (52.6%), age group over 40 years (36.7%), married (53, 8%), working at the company for a period that ranges from 7 to 10 years (17%), administrative activity (68.5%), and a higher number of symptomatic workers and deaths in telework compared to on-site work. CONCLUSIONS: The results suggest that testing is important to refrain the virus spread in the company's work environments, as it allowed asymptomatic workers to be diagnosed with COVID-19. The study suggested that on-site work was not a transmission facilitator in the occupational environment, which points out the importance of preventive measures in the workplace and the adoption of remote work for the largest possible number of workers to improve the safety of employees, workers who remained in the on-site work modality.

Temporal Variation and Persistence of Methane Emissions from Shallow Water Oil and Gas Production in the Gulf of Mexico.

Methane emissions from the oil and gas supply chain can be intermittent, posing challenges for monitoring and mitigation efforts. This study examines shallow water facilities in the US Gulf of Mexico with repeat atmospheric observations to evaluate temporal variation in site-specific methane emissions. We combine new and previous observations to develop a longitudinal study, spanning from days to months to almost five years, evaluating the emissions behavior of sites over time. We also define and determine the chance of subsequent detection (CSD): the likelihood that an emitting site will be observed emitting again. The average emitting central hub in the Gulf has a 74% CSD at any time interval. Eight facilities contribute 50% of total emissions and are over 80% persistent with a 96% CSD above 100 kg/h and 46% persistent with a 42% CSD above 1000 kg/h, indicating that large emissions are persistent at certain sites. Forward-looking infrared (FLIR) footage shows many of these sites exhibiting cold venting. This suggests that for offshore, a low sampling frequency over large spatial coverage can capture typical site emissions behavior and identify targets for mitigation. We further demonstrate the preliminary use of space-based observations to monitor offshore emissions over time.

Automated method using direct-immersion solid-phase microextraction and on-fiber derivatization coupled with comprehensive two-dimensional gas chromatography high-resolution mass spectrometry for profiling naphthenic acids in produced water.

Naphthenic acids (NAs) are naturally occurring organic acids in petroleum and are found in waste waters generated during oil production (produced water, PW). Profiling this class of compounds is important due to flow assurance during oil exploration. Compositional analysis of PW is also relevant for waste treatment to reduce negative impacts on the environment. Here, comprehensive two-dimensional gas chromatography coupled with high-resolution mass spectrometry (GC×GC-HRMS) was applied as an ideal platform for qualitative analysis of NAs by combining the high peak capacity of the composite system with automated scripts for group-type identification based on accurate mass measurements and fragmentation patterns. To achieve high-throughput profiling of NAs in PW samples, direct-immersion solid phase microextraction (DI-SPME) was selected for extraction, derivatization and preconcentration. A fully automated DI-SPME method was developed to combine extraction, fiber rinsing and drying, and on-fiber derivatization with N-methyl-N­tert-butyldimethylsilyltrifluoroacetamide (MTBSTFA). Data processing was based on filtering scripts using the Computer Language for Identifying Chemicals (CLIC). The method successfully identified up to 94 NAs comprising carbon numbers between 6 and 18 and hydrogen deficiency values ranging from 0 to -4. The proposed method demonstrated wider extraction coverage compared to traditional liquid-liquid extraction (LLE) - a critical factor for petroleomic investigations. The method developed also enabled quantitative analysis, exhibiting detection limits of 0.5 ng L-1 and relative standard deviation (RSD) at a concentration of NAs of 30 µg L-1 ranging from 4.5 to 25.0%.

Psychosocial Risks and Mental Disorders among Mexican Oil Workers / Riesgos psicosociales y trastornos mentales en trabajadores petroleros mexicanos / Riscos psicossociais e transtornos mentais em trabalhadores petrolíferos mexicanos

The psychosocial risks faced by workers can influence their health as well as job performance and satisfaction. However, this phenomenon among Mexican workers in the oil industry has not been well studied. The purpose of this study was to analyze the association of stress and job-related burnout with mental disorders among oil workers in the southeastern region of Mexico. Materials and methods: This cross-sectional and analytical study included 501 workers from the onshore oil industry in the southeastern region of Mexico. The Work Burnout Inventory, the Symptoms of Stress Inventory, and the Goldberg General Health Questionnaire (ghq 28) were applied between October and November, 2016. Chi-square test was used to analyze the relationship between variables and the odds ratio was determined to establish the level of risk for mental disorders. Results: Moderate levels of stress (21.4l %), efficacy (41.5 %), cynicism (30.6 %), and exhaustion (39.7 %) were observed. Mental disorders were noted in 11.8 % of workers. Stress and burnout were associated with mental disorders (p < 0.05). Finally, workers who experienced stress and job burnout were more likely to have mental disorders (or = 12.96; 95 % ci [7.03­23.94]; p = 0.00). Conclusions:Stress and job burnout are risk factors for mental disorders among Mexican oil workers.

Conclusões: o estresse e desgaste laboral representam fatores de risco para o desenvolvimento de transtornos mentais em trabalhadores petrolíferos mexicanos.

Impacts of COVID-19 on the oil and gas industry in Brazil.

This study aimed to analyze the progression of COVID-19 cases on oil and gas workers in Brazil. This is a descriptive research based on secondary data available in the COVID-19 Monitoring Bulletins of the Ministry of Mines and Energy and news about outbreaks on digital media. The findings show that the numerous news reports published on digital media indicate unhealthy working conditions, and workers' representatives appear as the main source of these findings. Managers' failure in health surveillance of this working class were also observed as to the frequent omission of official data and compulsory notifications on the health and safety of oil and gas workers.

Este estudo teve como objetivo analisar a evolução dos casos de trabalhadores do setor de petróleo e gás afetados pela covid-19 no Brasil. Tratou-se de uma pesquisa descritiva, realizada a partir de dados secundários disponíveis nos boletins de monitoramento da covid-19 do Ministério de Minas e Energia e das notícias sobre surtos de covid-19 em petroleiros publicadas nas mídias digitais. Concluiu-se que as inúmeras notícias publicadas pelas mídias digitais refletem condições de trabalho insalubres, e os representantes dos trabalhadores surgem como a principal fonte desses achados. Foram observadas ainda falhas na vigilância em saúde por parte dos gestores dessa classe trabalhadora no que concerne à frequente omissão de dados oficiais e às notificações compulsórias sobre a saúde e a segurança dos petroleiros.

Offshore medical evacuations due to non-occupational illnesses.

Introduction: Offshore work is a continuous challenge for occupational safety and medicine, as well as for qualification, training, and worksite logistics. In such conditions, any health issue requiring disembarkation incurs a serious burden. Objectives: To evaluate the number and causes of non-occupational medical evacuations among Brazil's offshore units between 2016 and 2019. Methods: The database of consultations performed by the medical services company International Health Care for offshore units on the Brazilian coast of client companies from 2016 to 2019 was reviewed. Results: Of the 1140 identified medical evacuations, 937 were non-occupational. Conclusions: Due to the increase in safety culture, non-occupational illness has become the most common reason for medical evacuations. Without understanding and prevention of such causes, expenses will increase for companies with offshore operations.

Introdução: O trabalho offshore é um constante desafio em termos de segurança e medicina do trabalho.

Conclusões: Devido à grande cultura de segurança do trabalho, o adoecimento se tornou a causa mais comum de desembarques. O não entendimento e prevenção dessas causas também causam custos às empresas.

A saúde do trabalhador offshore: uma análise sanitarista sobre a realidade das negociações coletivas do trabalho em alto-mar / The health of the offshore worker: a sanitarian analysis of the reality of collective negotiations on the high seas

Considerando como tema central a saúde do trabalhador, o objetivo do presente estudo foi analisar a realidade das negociações coletivas do trabalho em alto-mar, avaliando como hipótese a fragilidade no controle do poder público sobre o processo produtivo como limite da efetividade de uma realidade em prol da saúde e segurança dos trabalhadores e trabalhadoras desse setor. Para isso, foram pontuados os seguintes objetivos específicos: a) apresentar distintas concepções e valorações do trabalho humano através das perspectivas sanitarista, ocupacional e previdenciária; b) apontar como a saúde do trabalhador offshore se organiza e vem sendo estruturada; c) elencar quais são os principais atores, práticas, possibilidades e obstáculos na consolidação do controle público na garantia de direitos do trabalhador offshore; d) pautar limites e possibilidades contidos nas negociações (acordos e convenções) no âmbito de acidentes e adoecimentos decorrentes da relação laboral da categoria; e e) analisar aspectos do acidente ocorrido no dia 11 de fevereiro de 2015 na unidade estacionária de produção, armazenamento e transferência de óleo e exportação de gás da empresa BW Offshore denominada Cidade de São Mateus (FPSO CDSM), que na ocasião era afretada pela Petrobras. Assim sendo, o leitor poderá observar detalhes a respeito do mercado de petróleo e gás, tais como sua importância no contexto econômico nacional, a inserção massiva da terceirização nas relações de trabalho e prestação de serviços dessa cadeia produtiva, além das representações sindicais desse universo laborativo em específico. Será possível, ainda, compreender as diferentes concepções de saúde do trabalhador, que revelam as abordagens e os interesses diversos no campo teórico-prático quando o assunto é a saúde e a segurança no ambiente laborativo, além de se familiarizar com aspectos garantidores ou vulnerabilizantes de direitos frente às negociações coletivas entre os representantes sindicais dos trabalhadores offshore da empresa BW Offshore. Por fim, será possível observar uma análise e tentativa de compreensão mais ampla do acidente supracitado, sob a ótica do déficit de controle público sobre os processos produtivos empresariais e, por consequência, da manutenção da inobservância do Estado em mediar essas relações. (AU)

Considering workers' health as a central theme, the objective of this study was to analyze the reality of collective negotiations on the high seas work, considering as a hypothesis the fragility in the control of the public power over the productive process as a limit of the effectiveness of a reality in favor of the health and safety of workers in this sector. For this, the following specific objectives were scored: a) To present different conceptions and valuations of human work through the sanitarian, occupational and social security perspectives; b) To point out how the health of the offshore worker is organized and has been structured; c) List the main actors, practices, possibilities and obstacles in consolidating public control in guaranteeing the rights of offshore workers; d) To guide limits and possibilities contained in the negotiations (agreements and conventions) in the context of accidents and illnesses resulting from the employment relationship of the category; e) Analyzing aspects of the accident that occurred on February 11, 2015, at the stationary production, storage, and oil and gas export unit of the company BW Offshore, known as Cidade de São Mateus (FPSO CDSM), which was chartered by Petrobras.

The practice of ergonomics as a design discipline in the basic design of oil platforms.

BACKGROUND: Ergonomics is increasingly gaining ground in projects in the energy sector, as well as in the continuous process industry, although the discipline is still framing its space in this milieu. This issue emerges from the designers' lack of familiarity with ergonomics work, especially in engineering design projects, combined with the usual expectations of organizations regarding the participation of ergonomists and the deliverables they ought to develop throughout the project. OBJECTIVE: This study aims to report the participation of a team of ergonomists in an oil platform basic design, discussing ergonomics structuring as an emerging design discipline. METHODS: This qualitative study used participant observation as a methodology approach aligned with the theoretical framework of Activity Ergonomics (AE). The data collection occurred between October 2018 and June 2020 in Rio de Janeiro, Brazil. RESULTS: The results show the challenges faced by the ergonomics team and strategies adopted in order to create technical specifications (TS), which will determine the work conditions in the future platforms. An evolution in relation to the practice of Ergonomics during this project can be pointed out, even though part of its scope of action remains to be better understood among the design team. CONCLUSION: Considering oil platform project contexts, this work highlights how ergonomics can help integrate the different rationalities that compose the design process.

Integrating work into the design: The case of offshore maintenance.

BACKGROUND: Ergonomics in design is intended to close the gap between what is designed and the real work. This study discusses the creation of technical ergonomics requirements for the basic design stage of workshops on offshore platforms. OBJECTIVE: This paper intends to show how the ergonomics discipline contributes to integrating knowledge on the real work of the maintenance crew with the design. METHODS: This case study uses procedures, data collection, and analysis guided by the Ergonomics of the Activity's (EA) theoretical framework, focused on design projects. RESULTS: The results show how ergonomics contributed to a better understanding of maintenance work, as well as how this knowledge was integrated into the project design. This occurred both through the construction of a new layout and equipment list, and through the development of technical specifications. These products enable greater operational efficiency, reductions in the costs of alterations in the next stages of the project, and improvement in working conditions. CONCLUSIONS: This work points to the need for new studies on platform maintenance work, in addition to studies that deepen the debate on consolidating ergonomics practice in design projects.

Active Control System to Prevent Malfunctioning Caused by the Pressure Difference in Gasket Plate Heat Exchangers Applied in the Oil and Gas Industry.

In the oil and gas industry, heat exchangers are subject to loads that cause malfunctioning. These loads are divided into thermal and mechanical stresses; however, most efforts are focused on studying thermal stresses. The present work reduces mechanical stresses by mitigating pressure events in a gasket plate heat exchanger (GPHE). GPHE requires that the hot and cold stream branches have approximately the same pressure. Thus, the work focuses on controlling the pressure difference between the branches. A test bench was used to emulate, on a small scale, the typical pressure events of an oil production plant. A control valve was used in different positions to evaluate the controller. In the experiments, it was observed that the best option to control the pressure difference is to use a hydraulic pump and control valve in the flow of the controlled thermal fluid branch. The reduction in pressure events was approximately 50%. Actuator efforts are also reduced in this configuration.

Quantifying Regional Methane Emissions in the New Mexico Permian Basin with a Comprehensive Aerial Survey.

Limiting emissions of climate-warming methane from oil and gas (O&G) is a major opportunity for short-term climate benefits. We deploy a basin-wide airborne survey of O&G extraction and transportation activities in the New Mexico Permian Basin, spanning 35 923 km2, 26 292 active wells, and over 15 000 km of natural gas pipelines using an independently validated hyperspectral methane point source detection and quantification system. The airborne survey repeatedly visited over 90% of the active wells in the survey region throughout October 2018 to January 2020, totaling approximately 98 000 well site visits. We estimate total O&G methane emissions in this area at 194 (+72/-68, 95% CI) metric tonnes per hour (t/h), or 9.4% (+3.5%/-3.3%) of gross gas production. 50% of observed emissions come from large emission sources with persistence-averaged emission rates over 308 kg/h. The fact that a large sample size is required to characterize the heavy tail of the distribution emphasizes the importance of capturing low-probability, high-consequence events through basin-wide surveys when estimating regional O&G methane emissions.

A comprehensive petrochemical vulnerability index for marine fishes in the Gulf of Mexico.

Oil and gas extraction activities occur across the globe, yet species-specific toxicological information on the biological and ecological impacts of exposure to petrochemicals is lacking for the vast majority of marine species. To help prioritize species for recovery, mitigation, and conservation in light of significant toxicological data gaps, a trait-based petrochemical vulnerability index was developed and applied to the more than 1700 marine fishes present across the entire Gulf of Mexico, including all known bony fishes, sharks, rays and chimaeras. Using life history and other traits related to likelihood of exposure, physiological sensitivity to exposure, and population resiliency, final calculated petrochemical vulnerability scores can be used to provide information on the relative sensitivity, or resilience, of marine fish populations across the Gulf of Mexico to oil and gas activities. Based on current knowledge of traits, marine fishes with the highest vulnerability scores primarily occur in areas of high petrochemical activity, are found at or near the surface, and have low reproductive turnover rates and/or highly specialized diet and habitat requirements. Relative population vulnerability scores for marine fishes can be improved with additional toxicokinetic studies, including those that account for the synergistic or additive effect of multiple stressors, as well as increased research on ecological and life history traits, especially for deep living species.

Occupational mortality in the New Mexico oil and gas industry.

New Mexico's oil and natural gas industry has the second highest occupational fatality rate among oil and gas workers in the nation. There is currently limited data available regarding the top contributing factors to occupational mortality specific to the state's oil and gas industry. This study seeks to understand causes of mortality among oil and gas workers in New Mexico between 2008 and 2018. To facilitate this study, case reports were obtained from the New Mexico Office of the Medical Investigator, and population data was acquired from the US Department of Labor. In this 11-year span, there were 73 cases, with an average annual mortality rate of 37 deaths per 100,000 oil and gas workers. Leading causes of death were vehicle accidents (36%), cardiovascular incidents (22%), and crush injuries (19%). The majority of vehicle accidents involved single vehicle accidents, and correct seat belt use was only documented 23% of the time. The majority of cardiovascular deaths were due to arteriosclerotic and atherosclerotic cardiovascular disease. Alcohol was present in 18% of cases, and drugs were present in 19% of cases with methamphetamine present in 10% of investigated deaths. This is the first study to directly include cardiovascular incidents in the leading causes of death; otherwise, this study reflects national data reporting vehicle accidents and crush injuries as the leading causes of death. Going forward, prevention measures should effectively target safe driving practices focusing on seatbelt use, and mitigation of workplace drug and alcohol consumption.

Retirement risks: Invasive coral on old oil platform on the Brazilian equatorial continental shelf.

The objective of this study was to report, for the first time, the presence of an invasive coral (Tubastraea tagusensis) in an oil platform on the Brazilian equatorial continental shelf. This structure is located more than 1200 km north from other oil and gas structures colonized by this coral. We also discussed the retirement and decommissioning of old biofouling-encrusted oil and gas platforms (~62 platforms) from decreased production and the current oil crisis, exacerbated by the COVID-19 pandemic. This presents an ecological concern due invasive coral range expansion and potential impacts to poorly studied ecosystems such as marginal shallow-water coral reefs and mesophotic ecosystems. It is imperative that mindful risk analysis and rigorous environmental studies must precede the installation of new oil and gas platforms. In addition, decommissioning of retired structures should take into consideration marine restoration and non-indigenous species dispersal, and more specifically, Tubastraea bioinvasion.

Sustainability Indicators System Based on Multicriteria Analysis: A Tool for the Management of the Sustainability of Offshore Oil and Gas Production Units.

The increasing production of oil and gas in the marine environment and the growing participation of companies of different nationalities and sizes require the use of tools to support the sustainable management of offshore oil and gas production units. This paper presents the results of the application of a sustainability indicator system, developed from the identification of the economic, environmental, social, and operational impacts of the activities of these production units. The sustainability performances of 3 oil and gas production units operating in the Brazilian marine environment were compared to the performance of one considered ideal, through the application of the PROMETHEE II and ordinal COPELAND multicriteria methods. The indicator system applied favored the analysis of the sustainability management of offshore oil and gas production activity in a multidimensional approach, considering the points of view of experts from various areas of knowledge, and proved to be a reliable tool to support the sustainable management of these offshore production units.

Cardiovascular risk factors among oil refinery workers: ecological study.

BACKGROUND: Monitoring the health of workers is indispensable to develop indicators to identify potential risk factors and the workload impact on illness and characterize their morbidity profile. OBJECTIVE: To identify modifiable and non-modifiable cardiovascular risk factors among employees of an oil refinery with fixed work schedule or allocated to shifts. METHODS: Ecological, exploratory, descriptive and quantitative study with data retrieved from the company's record system. We performed time series analysis of the prevalence of risk factors in the period from 2008 through 2017. RESULTS: We found an increasing trend in the prevalence of hypertension and diabetes and a decreasing trend for high cholesterol, high LDL, low HDL, smoking and coronary artery risk. The prevalence of hypertension increased, while that of all other risk factors, except for diabetes, decreased in 2017 by comparison to 2008. CONCLUSION: The analyzed sample is at medium risk for cardiovascular disease despite their young age, high educational level and available resources. We call attention to the need to systematize workplace health promotion programs.

Acidentes de trabalho fatais em empresa brasileira de petróleo e gás: análise da política de saúde e segurança dos trabalhadores / Work fatalities in a Brazilian oil and gas company: analysis of workers' health and safety policy

Resumo Este artigo analisa e discute as alterações da política de saúde e segurança (PSS) de uma empresa de petróleo e gás brasileira, a partir da ocorrência de um acidente ampliado em 2001, buscando compreender as repercussões destas mudanças no dia a dia dos trabalhadores. Trata-se de pesquisa de método misto com triangulação de informações epidemiológicas, pesquisa documental e abordagem qualitativa. O acidente com a plataforma de petróleo em 2001(RJ) foi considerado marco no processo de mudanças na PSS dessa empresa. Inúmeras ações e programas foram implementados e os investimentos na área de saúde e segurança aumentaram substancialmente. Identificou-se que tais iniciativas tiveram limitada participação dos trabalhadores no seu planejamento e elaboração, não priorizaram os problemas mais críticos e a ênfase se deu na instituição de normativas e auditorias para avaliação do cumprimento do estabelecido na prescrição. Por fim, observou-se que a aprendizagem sobre os acidentes do trabalho graves ou fatais é incipiente e não estruturada e que o sistema de consequências acarreta aos trabalhadores medo e insegurança, culpabilizando, em geral, o acidentado pela ocorrência, sem considerar os múltiplos fatores que influenciam e condicionam o acidente.

Abstract This paper aims to discuss the changes in the safety and health policy (SHP) of an oil and gas company from the enlarged accident that occurred in 2001, seeking out to understand the consequences of these changes in the daily activity of workers. It is a mixed study employing an epidemiological data triangulation method, documental research, and qualitative approach. The 2001 oil platform accident (RJ) was considered a milestone in the process of changes in the company's SHP. Several actions and programs have been implemented, and investments in health and safety have increased substantially. We identified that such initiatives had limited participation by workers in their planning and elaboration. They did not prioritize the most critical problems, and emphasis was placed on the establishment of standards and audits to assess compliance with the prescription. Finally, it was observed that learning about severe or fatal occupational accidents is incipient and unstructured, and the system of consequences triggers workers' fear and insecurity, blaming, in general, the injured person for the occurrence, without considering the multiple factors that influence and condition the accident.
