The maritime industry is a dangerous and highly technologicallysaturated sector. Unfortunately, advancement in automation and technologyhave not minimised human error as intended. Interaction between humansand technology in the industry is also overtly pre-scripted. The main reasonfor this is to reduce human error by ensuring predictability in interaction.Ultimately, investigations of non-routine interaction are often based on a hind-sight view of what went wrong in a given situation. This article analyses acollection of non-routine interactions that derive from a larger data corpus,using Discursive Psychology and Conversation Analysis. It argues that such astudy can capture what is missing from some investigations, namely, whatmakes sense for crews in the context of a given non-routine situation. Despitethe constraints and the challenges of technological complexity, this articleargues that reframing psychological matters in non-routine technologicallymediated interaction can be a new way of showing how such matters aredynamic, visible and manageable. This can inform the general debate of howto minimise human error, and more specifically, provide insight into the increas-ing inclusion of technology and as a consequence, the equally increasingamount of technologically mediated interaction that we will see in the future.
The report focuses on analysing on-deck accidents in offshore environments using data from the Health and Safety Executive (HSE) which covers the period 1980-2005. It applies the Accident Anatomy (AA) method, which maps accident causes and consequences using fault trees and cause-consequence diagrams (CCDs). Unlike previous analyses, this report aims to extract deeper insights into accident patterns beyond general statistics.
For this report, on-deck operations involve material handling, tool use, and equipment operation in offshore environments.
The study analysed 10,846 records that cover accident events on both fixed and floating offshore units. The report focuses on cases where injuries or fatalities occurred. The analysis described in the report mapped 77 accident-prone operations and provides a detailed causal understanding of offshore accidents.
Despite the exhaustiveness of the analysis, there are limitations related to the used data. The HSE records primarily document physical and operational aspects of the accidents, leaving out design-related or organisational factors. Next, probabilities for the accident events considered in the analysis are not provided. This is due to the incomplete nature of the sources and the lack of information on the number of opportunities for accidents. The computation of probabilities will be feasible if data on the frequency of use of relevant components, machines, personnel, and workplaces has been also collected.
Solid-state lithium battery (SSLB) is considered as the most potential energy storage device in the next generation energy system due to its excellent safety performance. However, there are still intimidating safety issues for the SSLB, due to it being still in the development stage. This paper gives an overview of the safety of SSLBs. First, advanced solid-state battery techniques are introduced. Second, the safety issues of SSLBs are discussed. Then, the safety enhancement techniques are provided. Finally, future research opportunities are presented. This paper aims to provide a reference for researchers in the fields of electronic and electrical engineering who want to make some efforts in SSLB safety.
Objectives Characterisation of worker injuries on board merchant ships is modest. Using telemedical service contacts in Denmark, we describe the worker injuries patterns and factors related to injury incidence. Methods The data for this study were based on contacts (n=1401) from ships to Telemedical Assistance Service (TMAS) in Denmark in 2004–2014, which were supplemented with data on the annual estimation of all seafarers from the Danish Maritime Authority (n=73 336). The final data included information on broad age groups, occupation and nationality. The outcomes were injuries from any cause and six broad categories of injuries characterised by anatomic location or type of injury. Results During the observation period of 11 years, there were 1401 contacts to TMAS due to injuries, of which 36% were in upper limb, 18% in lower limb and 13% in the head. Age-adjusted incidence rates for all injuries varied between 13.6 and 26.8 incidences per 1000 person-years in 2004–2014. In most types of injuries, younger and older seafarers had higher risk for injuries than seafarers aged 30–49 years. Depending on the type of injury, non-officers had threefold to fivefold increased odds of injuries compared with officers, the risk being highest for head injuries with an OR of 5.00 (95% CI 3.19 to 7.83). Non-officers from the European Union (EU) had higher risk in most types of injuries than non-officers from outside the EU, whereas the pattern of this risk was inverse among officers. Conclusions These findings suggest that non-officers and European seafarers have an increased risk for several types of injuries on board Danish-flagged merchant ships. Additionally, age affected risk with the younger (<30 years) and older (>50 years) seafarers having increased risk.
I december 2019 kommer fiskeriminister Mogens Jensen hjem fra Rådsmøde - de årlige kvoteforhandlinger
for 2020 i Bruxelles - med den besked, at jomfruhummerfiskeriet i Kattegat i fremtiden vil blive underlagt
kameraovervågning for forventeligt at nedbringe bifangst af torsk i dette fiskeri. Torskebestanden i Kattegat
er yderst presset og den generelle kvote er sat til nul. En mindre bifangstkvote på torsk blev således betinget
af denne overvågning, så man kan monitere torskefangsterne og sikre mod et udsmid af mindre torsk i fiskeriet,
en praksis, som myndighederne forudsatte yderligere ville forværre tilstanden i torskebestanden. Denne sidste
kausalsammenhæng er dog tvivlsom.
Torsk er således blevet en ”stop-art” for jomfruhummerfiskeriet og myndighedernes argumentation er, at
alternativet til kameraovervågning er et stop for jomfruhummerfiskeriet i Kattegat, da det ikke kan opretholdes
uden en bifangstkvote af torsk (Bilag 5). Udkommet af forhandlingerne kender vi, men det har ikke været
muligt at få yderligere indblik i selve forhandlingsprocessen; Havde de danske forhandlere alternative
positioner at falde tilbage på? Havde den danske delegation en forventning til reaktionerne i den danske
fiskerisektor? Var forhandlerne indstillet på at lukke jomfruhummerfiskeriet i Kattegat (proportionalitet)? Det
får vi muligvis aldrig indsigt i.
Given the move toward automation, an increased focus on the liability for technical defects must be anticipated. This brings into play liability regimes that have traditionally been less used in the maritime area. One of these liability regimes is product liability. It is the purpose of this contribution to examine the implications of product liability rules in the maritime area, seen in light of the automation of ships.
Objective: To promote the physical and mental health of employees in a maritime setting and provide knowledge and tools to assist seafarers in managing daily challenges.
Materials and methods: The intervention drew on a goal-based approach, including workshops, coaching,health checks, interviews, and questionnaires.
Results: A process evaluation was used to explore intervention challenges and barriers. Results show that an intervention at sea is complex and needs flexibility. Findings varied, and the main challenges were low participation in one group and lack of continuity due to Covid-19. Data showed a significant positive shift in how the crew rated perceived stress and a statistically significant increase in intake of salad, fish, and vegetarian food.
Conclusions: Workplace interventions in poor health status settings are complex, necessary, and possible, and management’s participation is crucial. Increased awareness was achieved. Learning outcomes: The results showed some positive changes, such as lower stress levels and more intake of salad, fish, and vegetarian food. Flexibility is important for workplace interventions. Work place interventions contribute to health and wellbeing with appropriate management support.
OBJECTIVES: Cardiovascular disease (CVD) is the leading cause of death globally and the second most frequent cause of death in Denmark. Due to their unique occupational environment, seafarers are exposed to numerous risk factors for CVD including lifestyle and work-related factors. This study aims to investigate CVD mortality among Danish seafarers by comparing them to the economically active reference population.
METHODS: This register-based cohort study included data on all Danish seafarers from 1993 to 2016 and compared them with the economically active Danish population not working as seafarers. The seafarers' mortality was calculated using piecewise stratified Cox regression adjusting for potential confounders. Mortality was further analyzed by diagnosis groups, vessel type and employment duration.
RESULTS: Among 52 861 seafarers, 4226 deaths were observed, with 866 (20.5%) of these attributed to CVD. Male seafarers had higher all-cause mortality in age groups 18-44 years (HR 1.46, 95% CI 1.33 to 1.62), 45-64 years (HR 1.43, 95% CI 1.37 to 1.50) and 65+ years (HR 1.32, 95% CI 1.26 to 1.39) compared with the reference population. CVD mortality was increased for male seafarers aged 45-64 years (HR 1.27, 95% CI 1.13 to 1.42) and 65+ years (HR 1.34, 95% CI 1.21 to 1.48). The mortality was higher for male seafarers for ischemic heart diseases, other forms of heart diseases, cerebrovascular diseases and diseases of arteries, arterioles and capillaries. CVD mortality was also observed based on vessel type.
CONCLUSIONS: The study provides evidence of elevated CVD mortality among Danish seafarers. Future research should focus on identifying effective strategies to improve the cardiovascular health of seafarers.
This report presents both the quantitative and qualitative results of a study on bullying and harassment in the Danish merchant fleet. The Minister for Industry, Business and Financial Affairs asked the
Danish Maritime Authority to conduct an external study of the extent of bullying and harassment among seafarers on Danish vessels. This task was assigned to the Centre of Maritime Health and Society at the University of Southern Denmark. The Commission for the study (in Danish) may be found on the Ministry of Industry, Business and Financial Affairs website. The report consists of seven chapters, and only the results are presented, by request from the Danish Maritime Authority. An English “Literature review” is made in a separate annex, with an analysis of other international research studies within the area of bullying and harassment. This has been requested by the Danish Maritime Authority. It is permitted to quote the results in the report on the condition that the University of Southern Denmark and the Centre of Maritime Health and Society is credited as the source.
The safety of people and cargo onboard is a key functionality of a commercial ship.
The health and well-being of seafarers and passengers is protected through an extensive set of technical specifications, standards and norms that govern the design and commissioning of all vessels.
They differ by ship type and size, while the specific services to be provided and the specific geographic regions to be served also play an important role in this respect.
The requirements are of national and international character and vary also with the classification society that will commission the ship. Thus in a broader sense, all competences related to ship design are related one way or another to maritime health.
Much of the design of ships is overseen by a naval architect or marine engineer. It is rare to have the involvement of a medical professional except in the cruise industry.
Purpose and tasks
To ensure that the design of a ship includes the requirements to protect the health and well being of seafarers. More specifically, to identify areas of intervention that go beyond the usual engineering curricula where, nonetheless, the safety dimension is embedded through international standardization.
