- Despite the continuous improvement of safety measures, maritime accidents remain a concern in our society. Thus, as the literature has shown, over the last ten years, the frequency of groundings and collisions accidents in the maritime domain has increased. An official accident investigation is conducted for each serious maritime accident, however, the level of detail changes from accident to accident, hence, the details about human contributors and organizational issues are not systematically analyzed and reported in a way that makes future extraction of trends and comparisons possible. With the aim to better capture human and organizational factors, this paper proposes to utilize the Safety Human Incident & Error Learning Database (SHIELD) HF Taxonomy, which was developed in the context of the European Union SAFEMODE project, in line with the key components of NASA-HFACS, HERA, and Reason's Swiss Cheese Model. Therefore, in this study, ten collision and ten grounding maritime accidents reported by various maritime agencies are analyzed via the SHIELD HF Taxonomy to identify the main accident contributors, including design deficiencies. The paper demonstrates the benefits of using the SHIELD HF taxonomy for identifying the underlying causes as well as developing mitigating design solutions.

- Ship dismantling is the recommended recycling solution for the end of a ship's life, but the process is not free of occupational risk. Despite proper regulations, there are underlying chemical and physical hazards, mainly due to the cutting of steel parts, which is the core of the recycling process. The overall aim of this research study is to determine, in two case study examples, the ship recycling workers' potential occupational exposure by inhalation of chemical agents generated by the torch cutting process of coated and de-coated steel. This was carried out specifically through (i) monitoring and measuring ship recycling workers' local environment for the inhalable (total dust) and respirable (fine dust) fractions during their working operations, (ii) analysing the heavy metal content of the dust and (iii) calculating and comparing this against occupational exposure limits, (iv) comparing de-coating operations with cutting of coated and de-coated steel. Results of this study show that without further mitigation workers involved in torch cutting processes are at high risk of exposure to heavy metals by inhalation as these are exceeding the norms defined by regulatory bodies. © 2023 The Authors

- The current industrial environment relies heavily on maritime transportation. Despite the continuous technological advances for the development of innovative safety software and hardware systems, there is a consistent gap in the scientific literature regarding the objective evaluation of the performance of maritime operators. The human factor is profoundly affected by changes in human performance or psychological state. The difficulty lies in the fact that the technology, tools, and protocols for investigating human performance are not fully mature or suitable for experimental investigation. The present research aims to integrate these two concepts by (i) objectively characterizing the psychological state of mariners, i.e., mental workload, stress, and attention, through their electroencephalographic (EEG) signal analysis, and (ii) validating an innovative safety framework countermeasure, defined as Human Risk-Informed Design (HURID), through the aforementioned neurophysiological approach. The proposed study involved 26 mariners within a high-fidelity bridge simulator while encountering collision risk in congested waters with and without the HURID. Subjective, behavioral, and neurophysiological data, i.e., EEG, were collected throughout the experimental activities. The results showed that the participants experienced a statistically significant higher mental workload and stress while performing the maritime activities without the HURID, while their attention level was statistically lower compared to the condition in which they performed the experiments with the HURID (all p < 0.05). Therefore, the presented study confirmed the effectiveness of the HURID during maritime operations in critical scenarios and led the way to extend the neurophysiological evaluation of the HFs of maritime operators during the performance of critical and/or standard shipboard tasks.
