Background:
The third edition of the International Medical Guide for Ships (IMGS) was published in 2007 and supported a main principle of the newly adopted International Maritime Labour Convention (MLC) 2006: to ensure that seafarers are given health protection and medical care as comparable as possible to that which is available to workers ashore. In 2021, the revisions and drafting of the fourth edition of the IMGS began. Taking the COVID-19 pandemic into consideration, it was decided that a stakeholder study was necessary to ascertain the usefulness and practicality of the guide as well as provide input for which new topics to include.
Materials and methods:
The study applied data triangulation, with respondents from a geographically
broad sample of the International Maritime Organization‘s five regional areas of the world. The data was analysed using thematic analysis.
Results:
The results show that the IMGS is widely known and used among persons involved in medical care on board ships, but the IMGS is not as practical as stakeholders would wish it to be. For the guide to be useful, it must be ensured that telemedical advice information is included and if possible, ensure there is one single and global medical guide. Also, there is a need for new medical information, and respondents pointed to pandemic information, medicines list, medical chest, mental health issues, a women’s section, updated cardiopulmonary resuscitation instructions, human immune defect virus information (human immune defect-virus) and information on how seafarers may self-monitor and be monitored on board in relation to chronic diseases.
Conclusions:
Respondents understand a medicine chest on board is mandatory according to the MLC 2006, 98% are familiar with its content, and 86% use the IMGS.
Offshore grids can play key roles in the transition of energy systems toward sustainability. Although they require extensive infrastructure investments, they allow for the exploitation of additional resources and may be important in providing for part of the increasing electricity demands driven by sector coupling. This paper quantifies the socioeconomic value of offshore grids and identifies their major drivers, performing energy system optimization in a model application of the northern–central European energy system and the North Sea offshore grid towards 2050. The increasing wake loss with the sizes of hub-connected wind farms is integrated in the modeling. We find that without sector coupling no offshore grid may develop, and that the higher the level of sector coupling, the higher the value of offshore grids. Therefore, it can be strongly stated that offshore grid infrastructure development should not be discussed as a separate political topic, but seen in connection to sector coupling.
To evaluate the transportation time reliability of the maritime transportation network for China’s crude oil imports under node capacity variations resulting from extreme events, a framework incorporating bi-level programming and a Monte Carlo simulation is proposed in this paper. Under this framework, the imported crude oil volume from each source country is considered to be a decision variable, and may change in correspondence to node capacity variations. The evaluation results illustrate that when strait or canal nodes were subject to capacity variations, the network transportation time reliability was relatively low. Conversely, the transportation time reliability was relatively high when port nodes were under capacity variations. In addition, the Taiwan Strait, the Strait of Hormuz, and the Strait of Malacca were identified as vulnerable nodes according to the transportation time reliability results. These results can assist government decision-makers and tanker company strategic planners to better plan crude oil import and transportation strategies.
This study investigates how the recognition and exploitation of entrepreneurial opportunities influence small business performance via interactions with firm-level innovation capability and learning orientation. We frame the study within the maritime-sector context and seek to contribute to the understanding of how the interplay between opportunity recognition, exploitation, innovation capability and learning orientation affects the entrepreneurial performance of local businesses when there is a technological policy change. The study further frames its arguments from a dynamic capability perspective and tests its arguments with data from 284 local businesses operating in the Port of Tema. Findings reveal that opportunity exploitation and learning orientation as well as their interplay have a positive and significant effect on entrepreneurial performance. The study consequently presents local micro-entrepreneurial reactions to macro-level policy changes within the maritime sector – an issue that has largely remained uninvestigated in the African business literature due to maritime blindness.
Climate change is affecting the oceans with increased sea levels, ocean acidification and extreme weather affecting coastal ecosystems. This necessitates a new model for climate and marine law, because existing law and policy are insufficient to tackle adaptation and mitigation impacts upon the marine environment. Presently, we do not know what it takes to integrate and balance climate legislation and governance when faced with unknown problems. The concept of Blue Economy is new and originates from the United Nations Conference on Sustainable Development. This chapter explores how one can best build new knowledge that can integrate climate law and marine governance. It does so by proposing the creation of a nexus between ecosystem-based regulations and marine spatial planning in order to create a new paradigm for effective and inclusive Blue Economy, using a systemic multi-regulatory framework (Global, Regional and National).
The Faroe Islands are currently struggling to find their feet in a new context of globalization and changing international requirements on fishery management best practices, as exemplified by United Nations protocols and agreements. We introduce the Faroese fisheries effort management system for cod, haddock and saithe, which represents an innovative attempt to tackle the challenges of mixed fisheries by means of a combination of total allowable effort implemented through days-at-sea and extensive use of closed or limited access areas. Subsequently, we present and discuss controversies concerning the system's ability (or lack thereof) to achieve a level of fishing effort that produces long-term sustainability. Over the years the system has proven able to evolve and overcome challenges, and the Faroe Islands are currently considering adding a proper fisheries management plan to the system to achieve fishing at maximum sustainable yield. However, finding support for this plan presents a challenge due particularly to an enduring gap between the perspectives of scientists and actors in the catching sector. Finally, we outline some actions that could be taken to reduce the gap and hence facilitate reform of the system: 1) integration of the consultative/advisory process; 2) obtaining tailor-made advice for the Faroese effort management system from the relevant scientific body; 3) establishment of a transparent mechanism for monitoring and regulating fishing effort; 4) clarifying the effectiveness of the prevalent system of closed areas.
This study explored xanthan gum hydrogel coatings as an approach to more environmental friendly fouling control strategies. Xanthan gum served as a filler in a conventional rosin/acrylic coating matrix, leading to the formation of a 150 μm thick gel layer on the coating surface upon seawater exposure. While biocide-free xanthan hydrogel coatings did not have significant antifouling capabilities, a synergistic effect between hydrogel and cuprous oxide was observed. During field tests at the CoaST Maritime Test Center (CMTC), it was found that the cuprous oxide concentration could be reduced by at least 50 wt% for the hydrogel coating without compromising the antifouling performance. Two possible causes were identified. First, the hydrogel coating could maintain a higher release rate over a prolonged period and second, the hydrogel was able to accumulate Cu2+, increasing retention time on the surface, creating a hostile environment. A synergistic enhancement in gel strength, yield point, and flow point was observed when xanthan was combined with konjac mannan. While promising for static applications, the rheological assessments of the different gels highlighted challenges for the application in dynamic settings like moving ships.
For more than a century, conventional marine vessels spatter the atmosphere with CO2 emissions and detrimental particles when operated by diesel motors/generators. Fuel cells have recently emerged as one of the most promising emission-free technologies for the electrification of ship propulsion systems. In fuel cell-based ship electrification, the entire marine power system is viewed as a direct current (DC) microgrid (MG) with constant power loads (CPLs). A challenge of such settings is how to stabilize the voltages and currents of the ship’s grid. In this paper, we propose a new modified backstepping controller to stabilize the MG voltage and currents. Finally, to study the performance and efficiency of our proposal, we run an experiment simulation using dSPACE real-time emulator.
The authors revisit the literature on the use of expatriates and specifically Boyacigiller (1990) and examine whether OW Bunker, a Danish bunker oil trader, filled positions at its foreign units with traders transferred from its other units (expatriates). The authors test the generalizability and robustness of past findings on this topic by using a different dependent variable, sample, and methodology. Design/methodology/approach: By searching the traders' LinkedIn profiles and consulting secondary sources, the authors obtain data on current and previous positions and work location and type of customer handled (global or local). Using qualitative comparative analysis (QCA), the authors analyze 236 hiring decisions made between 1983 and 2014. Findings: The authors find that OW transferred expatriates, principally home-country nationals, to handle global customers in its large foreign subsidiaries located in high-income countries. In another clear pattern, expatriates were used to start new foreign subsidiaries. These results generally confirm those of Boyacigiller. However, and contrary to her findings, none of our scenarios for internal transfers feature expatriates being sent to culturally and institutionally distant subsidiaries unless it is to serve global customers, casting doubt on the idea that a major reason for using expatriates is to remedy a local shortage of skills or to handle political risk. Originality/value: The authors test the generalizability of Boyacigiller’s (1990) findings and confirm a large part of it. They extend her study by demonstrating that MNEs deploy expatriates not only to distant countries but also to close ones.
Within realistic time constraints we successfully trained six occupational health and safety professionals in applying a Design Thinking (DT) approach to solve complex musculoskeletal and psychosocial problems at work. DT may be defined by the double diamond model pointing to a non-linear and user-centred problem-solving process iterating through divergent and convergent phases A key characteristic of DT is the ability to frame a problematic situation in new and interesting ways. The training was done in a full-day workshop followed by a learning-by-doing phase in which they planned and completed design sprint workshops in companies. The professionals went from novices into advanced beginners according to the Dreyfus model of skill acquisition. In the overall question of the usefulness of DT in OHS management, the average rating went from 6 before the training course to 9.5 after. In an evaluation of the DT approach on a 1–5 scale they rated design sprints at 3.8 to be more appropriate to manage complex problems than the methods they normally used. However, more experience seems necessary to adopt the DT mind set of an iterative process, in which they need to decide which tools to use in an emergent, nonlinear and iterative fashion.
