“…Besides reducing inspection time, there are other motivations for using unmanned solutions. In particular, while working inside the WTB, the workers are facing risks due to fires, explosions, falling from high ground or slipping, high voltage equipment, static electricity build-up, presence of hazardous chemicals and lack of oxygen [71][72][73]. Unmanned inspections of WTB interior could also reduce inspection costs, as they did in the exterior inspections [21], by reducing required crew size, marine vessel number needed for offshore WT inspections and lower the WT downtime.…”

Interior and exterior wind turbine blade inspections are necessary to extend the lifetime of wind turbine generators. The use of unmanned vehicles is an alternative to exterior wind turbine blade inspections performed by technicians that require the use of cranes and ropes. Interior wind turbine blade inspections are even more challenging due to the confined spaces, lack of illumination, and the presence of potentially harmful internal structural components. Additionally, the cost of manned interior wind turbine blade inspections is a major limiting factor. This paper analyses all aspects of the viability of using manually controlled or autonomous aerial vehicles for interior wind turbine blade inspections. We discuss why the size, weight, and flight time of a vehicle, in addition to the structure of the wind turbine blade, are the main limiting factors in performing internal blade inspections. We also describe the design issues that must be considered to provide autonomy to unmanned vehicles and the control system, the sensors that can be used, and introduce some of the algorithms for localization, obstacle avoidance and path planning that are best suited for the task. Lastly, we briefly describe which non-destructive test instrumentation can be used for the purpose.

“…The other high-risk operational activity in the petrochemical industry is the confined space entry and it is defined as an enclosed or partially enclosed area that is big enough for a worker to enter (Stojković, 2013). The hazards may not be obvious and it is imperative that the assessments must be done by a qualified person familiar with the confined space and the work to be done in that space (Karthika, 2013).…”

Purpose This paper aims to report on the development of a model to improve process health and safety within the context of a petrochemical environment to achieve a generative health and safety culture within that sector. Design/methodology/approach A quantitative research methodology and deductive research approach were used in the study. A survey was conducted in a major petrochemical enterprise in the KwaZulu-Natal province of South Africa with 259 returned and duly completed questionnaires. The data was statistically analysed using statistical packages for social science version 25. Findings This study found that the key process health and safety critical drivers needed to grow a generative process health and safety culture were leadership commitment, chemical exposure management, health and safety risk assessment, process hazard analysis and permit to work. Research limitations/implications This study was conducted in the KwaZulu-Natal Province of South Africa within the petrochemical industry. Because of self-reported methods of data collection, there is a probability of bias existing in the results of the study. Practical implications The contribution of this research is to understand, based on theoretical assumptions, how health and safety improvement could be institutionalised in an organisation. The developed model can be used as a practical tool. Social implications This paper is part of the larger discussion of increasing importance in health and safety policy-making. This study aims at contributing to the literature in the field of health and safety by incorporating the drivers towards a generative process health and safety culture. Originality/value This study provides a model to assist senior management to reduce exposure to process health and safety hazards in the petrochemical industry and improve overall performance.

“…[3,4]. This is because there are many potential hazards in confined spaces, such as atmospheric hazards (e.g., poisoning, asphyxiation, and explosions) and physical hazards (e.g., mechanical, electrical, engulfment, and falls) which have a high potential to result in fatal accidents [5][6][7][8][9][10][11].…”

Background The high number of confined space incidents in Malaysia suggests that working in a confined space exposes workers to a substantial risk of serious injury or fatality. The rapid development of industry and technology has increased the need to work in confined spaces and significantly impacted the risk management of confined spaces. Utilizing past incident data through investigation will help develop risk management and preventive measures related to confined spaces. As a result, this paper will conduct a fatal incident investigation associated with confined spaces from 2010 to 2020 in Malaysia. Methodology The incident investigation uses the improved systematic casual analysis technique (SCAT) to identify the immediate cause and the direct cause. From the identified fatal incidents immediate causes, the study will highlight the main hazard that causes fatal incidents in confined spaces. The preventive measure is developed based on the main hazard of confined spaces that cause fatalities. Result The result of the study has identified that physical and atmospheric hazards are the main factors that cause fatal incidents associated with confined spaces in Malaysia. Moreover, from the SCAT checklist, the study has revealed that failing to use PPE properly and hazardous environmental conditions are the main immediate cause of fatal incidents in confined spaces. Conclusion Effective risk management of confined spaces, with a particular focus on addressing atmospheric and physical hazards, is crucial for preventing accidents, especially those incidents resulting in fatalities. Future studies should expand their focus to include injuries and near-miss events in confined spaces, aiming to develop more effective and inclusive safety measures by analyzing a broader range of incidents.
