Understanding seafarers’ physical and mental health

ABSTRACT This study delves into the comprehensive examination of the quality of life of Turkish seafarers operating worldwide, utilizing the SF-36 health Survey to assess both physical and mental health components. Statistical analyses of the data, gathered from 955 Turkish seafarers, offer insights into the demographic factors influencing their quality of life. Univariate and multivariate logistic regression analyses were used to determine the association of demographic and work-related characteristics with psychological and mental health status. Findings indicate that Turkish seafarers exhibit a physical health status better than migrant female workers but worse than university professors, and approximately the same as aircraft manufacturing and healthcare workers, aligning with existing literature on other occupational groups. Moreover, older age groups, particularly those in authoritative positions such as master’s and chief engineers, demonstrate significantly poorer physical health. The study also highlights the mental health challenges faced by cadets, suggesting interventions to address their vulnerable state. Notably, while 25.2% of participants exhibit low physical health scores, a concerning 46.0% report poor mental health scores.

Orion SysML Model, Digital Twin, and Lessons Learned for Artemis I

AbstractIn 2015 it was recognized by NASA's Orion Chief Engineer that NASA's design insight into the Orion subsystems for Artemis I was not sufficient to provide standard engineering support to flight operations. To address these concerns, provide an opportunity to apply emerging model‐based systems engineering and digital twin methodologies, and provide opportunities for employees across NASA to get hands‐on training, an Orion Digital Twin pilot project was initiated in 2020 as part of the Agency's Digital Transformation initiative. With the increase in complexities of spacecraft, and decreased time to made decisions during missions in critical or emergency situations, digital modeling and integration of design can reduce the time to answer questions by days and the required human resources by an order of magnitude over conventional approaches and was identified to be a critical capability for NASA's future. This paper describes the genesis of the Orion Digital Twin pilot project, efforts undertaken, a reproducible methodology to take available system information from a mature program to create an executable SysML model that supports a link to the physical asset, and associated lessons learned and project deliverables.

Roles and challenges of seafarers for implementation of energy efficiency operational measures onboard ships

As international shipping contributes to 2.89% of global carbon dioxide (CO2) emissions, the International Maritime Organization (IMO) has set a target of reducing the carbon intensity by at least 40% by 2030 and 70% by 2050 compared to 2008. To achieve these goals, the IMO has developed guidelines and regulations for enhancing energy efficiency in ship design and operation, such as adopting various operational measures, low-carbon fuels, innovative technologies, and retrofits. A purposive sampling strategy was employed in this study to ensure a representative sample, engaging seafarers, ship managers, and technical and operations managers from 46 shipping companies worldwide. The study demonstrates that seafarers actively engage in various energy efficiency practices, with navigation, cargo works, deck operations, and port-related measures divided between the master and deck crews. Chief engineers and engine crews are involved in power generation, propulsion engines, and engine load management. Onshore technical managers oversee both groups to ensure the successful implementation of the Ship Energy Efficiency Management Plan (SEEMP). However, seafarers encounter challenges such as increased workload, additional paperwork, heightened inspections by regulatory bodies, enhanced planned maintenance, and increased technical difficulties in executing SEEMP onboard ships. Furthermore, the implementation of SEEMP has also affected the traditional work culture of crewmembers, who rarely receive recognition or incentives for their efforts. As part of its recommendations, the study emphasizes the need for improved working conditions, training, and incentives, as well as introducing new technologies to reduce workloads and ensure compliance with SEEMP.

Competency Evaluation Of Non-Convention Fishing Vessel Crew (Case Study: 30-100 Gt Purseiner In Pati Regency And Pekalongan City)

Indonesia has ratified the international regulations concerning the competence of fishing vessel crews in the form of Standard of Training, Certification and Watchkeeping for Fishing Vessel Personnel (STCW-F) 1995. Many Indonesian fishermen’s competences are not up to standard. The study was conducted on non-conventional fishing vessels because in Indonesia the numbers are dominated.The purpose of this research is to identify and map the competency quality of non-conventional Fishing Vessel Crew in Pati Regency and Pekalongan City with regard to the marine certificates owned by ship crews according to the STCW-F standard. The analysis uses content analysis of regulations and Gap analysis of expertise competence for the Skipper, Chief Engineer, Chief Officer and First Engineer for Purseiner 30-100 GT in Pati and Pekalongan against Minister of Maritime Affairs and Fisheries Regulation Number 33 of 2021. The results show in Pati district and Pekalongan City: the competence of masters is 66.9% and 81.4%, Head of Engine Room 23.1% and 30%, Chief officer 66.9% and 9.1%, and First Engineers are 4.1% and 0%. Recommendations for the fulfillment of the provisions of the Expertise Competency Certification according to the ministerial regulation are by: increasing Awareness, increasing extension of the importance of certification,and strict enforcement of certification rules.

Seafarers Involvement in Implementing Energy Efficiency Operational Measures in Maritime Industry

The Fourth GHG Study 2020 of the International Maritime Organization (IMO) reported that 2.89% of total global anthropogenic CO2 emissions had been emitted by international shipping. IMO's initial strategy is to set carbon intensity goals of at least a 40% reduction in CO2 emissions per transport work by 2030, and a 70% reduction by 2050 must be met. This has led IMO to introduce guidelines for calculating energy efficiency in both the design and operation phases using the Energy Efficiency Design Index (EEDI), the Ship Energy Efficiency Management Plan (SEEMP), the Energy Efficiency Existing Ship Index (EEXI), and the Carbon Intensity Indicator (CII). In the decade between 2008 and 2018, the energy efficiency of international shipping operations advanced by one-third. By adopting energy efficiency design and operational measures and introducing innovative technologies, many shipping companies worldwide reported remarkable financial and environmental benefits by saving fuel on every voyage. Ships are operated by ashore technical managers and aboard crewmembers; thus, they are directly involved in implementing energy efficiency operational measures. Therefore, the scope of this study is only limited to ashore technical managers and aboard ship crews only. This study has found that Master and Deck Crews are directly involved in implementing the ship's navigation and port operation-related EE measures. In contrast, the Chief Engineer and Engine Crews are directly involved in all ships’ propulsion, power generation, and management-related operational EE measures to implement onboard ships. Since the ashore managers supervise the ship's Master and Chief Engineer, they have reasonable control in every aspect of the fleet's energy efficiency operations, from navigation to port operations and ship's propulsion to power generation and management.

Organisational Justice among Engineers at a South African Energy Provider: A Demographic Analysis

Employees’ perceived fairness may greatly influence their employee relations, attitudes and behaviours. A demographic analysis to investigate the perceived fairness among engineers at a South African energy provider has not yet been conducted. Thus, the purpose of the current research study was to analyse the demographics of engineers at a South African energy provider in terms of organisational justice. A quantitative research method was used and 229 engineers – 164 engineers, 44 senior engineers and 21 chief engineers – participated in the study. The results showed that there were no significant relationships between the demographic variables and organisational justice. There were significant differences in how the different occupational levels perceived procedural justice, but no difference in how they perceived interpersonal justice. For the chief engineers, gender and occupational level significantly predicted organisational justice. A practical implication of the study is that the findings provided useful insight regarding the occupational level of chief engineer who perceived procedural justice in a positive light, while the occupational levels of chief engineer and engineer held a positive perception regarding organisational justice. The contribution of the study lies in the fact that all occupational levels of engineers should be treated in the same way and that demographic differences should be taken into consideration in doing so. It is recommended that management encourage a culture of employee interactions since this will improve interpersonal justice; ensure transparency regarding what is happening in the organisation; and eliminate uncertainty through employee engagement sessions.

Influence of diagnostic and dynamic capabilities on frugal innovation development: An empirical study of the Thai auto parts industry

Cost management is the strategy of planning and controlling the costs associated with operating a business. The frugal innovation (FI) approach is therefore interesting because it is a way to reduce costs while innovating without requiring a high level of investments in capital, technology, and skills. Therefore, to understand the mechanism of FI development, this research aims to study the relationships and influences among the diagnostic capabilities (DiC), dynamic capabilities (DyC), and frugal process innovation (FPI) of Thai small and medium-sized enterprises (SMEs), which require a cost strategy to stay in the highly competitive auto parts industry. Causal research was conducted through surveys using questionnaires for data collection. Respondents were chief executive officers (CEOs), engineers, and senior technicians in their respective companies. Partial least squares-structural equation modeling (PLS-SEM) was used to assess the structural models and verify the research hypotheses. The findings revealed significant influences among three pairs of constructs: (1) DiC has a positive effect on DyC, (2) DyC has a positive effect on FPI, and (3) DiC has a positive effect on FPI. Accordingly, the results of this research reveal a guideline for FI development by creating DiC and improving organizational DyC. These notions improve organizational preparation for unexpected situations in the future.

Study of the structure of the working day in the Chief Engineer service of an industrial company

The heart of any innovative ecosystem is people who due to their motivation and skills are able to create something new. However, numerous studies and statistics characterizing the results of innovation reveal low level of its activity. The authors of the article reject the hypothesis of opportunistic behavior of the subjects of innovation as the main reason of their low innovative performance and focus their attention on the system organizational and managerial barriers hindering the intellectual labor productivity and, in particular, on the lack of time for experts to solve innovative problems. The study focuses on the specialists of the Chief Engineer service who ensure the implementation of the technical policy of industrial organizations. The article has aims to present the results of personalized analysis of time consumption of the engineers of one of the chief engineer services (Chief Technologist Department). The data obtained makes it possible to identify organizational and managerial barriers of producing technological innovation and formulate recommendations on overcoming them in terms of digital transformation. The authors have collected, analyzed and systematized the data on engineers’ working time consumption. They have also established the disproportionality of routine and innovative component of the engineers’ labor, suggested options for improving proportions at the basis of point and system scenarios for redistribution of the working time consumption that requires solving organizational issues of strategic character. The article focuses the attention on the fact that engineers need to be allocated certain time to form competencies to create and transfer new technology into production divisions, to absorb technological knowledge, prepare industrial organization to accept new technology. As the example of a system scenario implementation the authors adduce creation of the sectoral engineering centre.

A novel methodology to develop risk-based maintenance strategies for fishing vessels

Fishing vessels often encounter propulsion machinery faults, resulting in the main propulsion system (MPS) failure. MPS failure can lead to safety and economic loss. Maintenance programming is an effective way to mitigate MPS failures. Given the nature of the fishing business, corrective and preventive maintenance approaches are not best suited for fishing vessels’ maintenance needs. This study presents a risk-based maintenance (RBM) methodology to develop a maintenance plan for fishing vessels. The methodology uses simple steps to design a tailormade maintenance plan for a given vessel. Central to the methodology is the “MPS OOBN model” that assists in estimating maintenance interval time for MPS subsystems and components needing maintenance. The study used a new method, the “Goal-directed risk identification technique (Goal-DRIT)”, to define the risk factors employed in developing the “MPS OOBN model”. The RBM methodology is benchmarked with the publicly available literature, and it also demonstrates 24.78% savings in the budgeted maintenance cost, for an example fishing vessel operating in Ghana. The methodology and proposed models are recommended to the commercial fishing industry, chief engineers, and superintendents of marine vessels to aid their maintenance programme design needs.

Investigation of the Relationships Between Personality Traits of Leaders and Accidents in the Maritime Sector With Adaptation of the Five-Factor Personality Inventory Into Turkish

Despite the many developments in the maritime sector in recent years, the number of accidents is still at a significantly high level. Beyond the accident analysis, which is defined as the reactive process, it is clear that more studies are needed in this sector, taking into account the personal traits of the employees and with the foresight that these traits may cause accidents. Statistically significant relationships were determined in this analysis, as a result of the five-factor personality inventory adapted into Turkish and the questionnaire covering the accidents (Occupational accident and marine casualty) on the ships of 156 leaders (Masters, chief engineers and chief officers). Participants who don’t have an ‘occupational accident’ history have higher conscientiousness and agreeableness personality traits than those who have occupational accident history; when considered as facets, it was understood that they had a higher sense of duty, self-discipline, and ideas. In addition, relationships were determined between ‘marine casualty’ and personality traits only in the context of facets. It is seen that participants who don’t have marine casualty history have higher gregariousness and lower values compared to those who have marine casualty history. Evaluations were made and some conclusions were reached with the understanding that the relationships identified in this study are similar to the results of the research conducted in this field of different sectors.
