Background: Autonomous ships have the potential to increase operational efficiency and reduce carbon footprints through technology and innovation. However, there is no comprehensive literature review of all the different types of papers related to autonomous ships, especially with regard to their integration with ports. This paper takes a systematic review approach to extract and summarize the main topics related to autonomous ships in the fields of container shipping and port management. Methods: A machine learning method is used to extract the main topics from more than 2000 journal publications indexed in WoS and Scopus. Results: The research findings highlight key issues related to technology, cybersecurity, data governance, regulations, and legal frameworks, providing a different perspective compared to human manual reviews of papers. Conclusions: Our search results confirm several recommendations. First, from a technological perspective, it is advised to increase support for the research and development of autonomous underwater vehicles and unmanned aerial vehicles, establish safety standards, mandate testing of wave model evaluation systems, and promote international standardization. Second, from a cyber–physical systems perspective, efforts should be made to strengthen logistics and supply chains for autonomous ships, establish data governance protocols, enforce strict control over IoT device data, and strengthen cybersecurity measures. Third, from an environmental perspective, measures should be implemented to address the environmental impact of autonomous ships. This can be achieved by promoting international agreements from a global societal standpoint and clarifying the legal framework regarding liability in the event of accidents.
The regionalization process promoted by the EU's Common Fisheries Policy (CFP) enabled the formulation of a new governance arrangement at the sub-national regional level of the Northern Adriatic Sea (NAS). Given the potential for dominating narratives to foster simplified solutions for fishery management, the article sought to analyze discourse formations across Italian Regional Fishery Departments (RFDs) of the NAS. A discourse analysis based on the Discursive Agency Approach (DAA) delineated the discursive strategies, while a weak vs strong sustainability narrative was adopted to broadly group stakeholders into discourse coalitions. The results showed the presence of a dominating narrative in RFD settings, prioritizing the economic growth of the fishery sector - particularly the trawling industry - over current environmental concerns. The study points to a possibly increasing dominance of weak sustainability narratives in the Italian NAS and invites for stakeholders' representation to significantly broaden and diversify, enabling the development of multifaceted solutions to the NAS crisis.
Fishing and sand mining in Cambodia may not appear to have much in common. However, digging deeper reveals important parallels. Both fishing and sand mining support livelihoods and are connected to a limited natural resource. Meanwhile, they are both typified by precarious livelihoods, on the one hand, and overexploitation, on the other. In bringing these two topics together, the paper combines empirical qualitative research from two separate studies conducted by the co-authors in Cambodia, one in coastal fishing villages and another in the sand mining industry along the Mekong River. We argue that the interplay between fishing and sand mining has paradoxical impacts on livelihoods, supporting one group while undermining another. Using a precarity analysis lens, we show how an unconventional, and largely invisible frontier of natural resource exploitation—sand mining—is intertwined with fisheries, and expands our understanding of the relationship between precarious labour, environmental change, and livelihoods.
Recent advances, especially in deep learning, allow to effectively detect ship targets in surveillance videos. However, the translation of these detections to the real-world locations of ships has not been sufficiently explored. The common approach in the literature is using a transformation matrix to convert a pixel to a real-world coordinate. However, this approach has three shortcomings: first, a set of reference point pairs has to be manually prepared to establish the matrix; second, the matrix always maps a pixel to the same real-world coordinate, ignoring that there is no one-to-one correspondence between discrete pixel coordinates and continuous real-world coordinates; third, this approach can only work with one camera. In light of this, we propose a technique PixelToRegion that explicitly takes into account the uncertainty in coordinate conversion by mapping each pixel to a spatial polygon. Next, we propose a new algorithm MCbSLE that can estimate ship locations using pixel sets from multiple cameras. The precision of location estimation by MCbSLE is enhanced through spatial intersection between polygons from different cameras. Experiments are conducted under 16 carefully designed multi-camera settings to evaluate MCbSLE wrt four factors: different ports, the number of cameras, the distance between cameras, and camera headings. Results on one-day ship trajectory data show that (1) an 79.8% accuracy in the number of coordinates can be achieved by MCbSLE when there are no more than 10 ships in camera views; (2) using multiple cameras can improve the precision of location estimation by one order of magnitude compared with using one camera.
Background: Evidence on workplace safety and health promotion interventions shows that the
interventions have failed to demonstrate substantial benefits for seafarers. It is therefore important to explore what is the evidence of interventions with empowering elements regarding seafarers’ safety and health. This study aims to examine what is known about health promotion interventions in a maritime setting and whether they include an empowerment perspective. And secondly, what were the effects of these efforts. Methods: We systematically searched PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information/Web of Science (ISI/WOS), and SCOPUS up to July 2022 by using standard keywords including empowerment in the maritime setting. Data extraction was done by three independent reviewers. The quality of included studies was assessed by using the critical appraisal checklists from Joanna Briggs institute. Results: From 3313 studies initially identified, 10 articles met the inclusion criteria and were included in this review. Interventions covered a wide range of topics such as educational interventions on safety, first aid training, weight management, healthy eating, sexual harassment, alcohol abuse, and cancer prevention training. None of the studies applied a specific theory or definitions of empowerment
even though their aim was to increase seafarers’ empowerment in these areas. Conclusion: The studies focused on improving the safety and health status of the seafarers, however, they had no explicit focus on participation and empowerment. Increasing research with an empowerment approach in maritime sector is recommended to enhance the feasibility and
success of the programs in this hard-to-reach occupation.
This paper presents a detailed risk assessment framework tailored for retrofitting ship structures towards eco-friendliness. Addressing a critical gap in current research, it proposes a comprehensive strategy integrating technical, environmental, economic, and regulatory considerations. The framework, grounded in the Failure Mode, Effects, and Criticality Analysis (FMECA) approach, adeptly combines quantitative and qualitative methodologies to assess the feasibility and impact of retrofitting technologies. A case study on ferry electrification, highlighting options like fully electric and hybrid propulsion systems, illustrates the application of this framework. Fully Electric Systems pose challenges such as ensuring ample battery capacity and establishing the requisite charging infrastructure, despite offering significant emission reductions. Hybrid systems present a flexible alternative, balancing electric operation with conventional fuel to reduce emissions without compromising range. This study emphasizes a holistic risk mitigation strategy, aligning advanced technological applications with environmental and economic viability within a strict regulatory context. It advocates for specific risk control measures that refine retrofitting practices, guiding the maritime industry towards a more sustainable future within an evolving technological and regulatory landscape.
Long considered a cultural contact zone, the Mediterranean has become a weaponised border zone keeping refugees from Africa and the MiddleEast away from ‘Fortress Europe’. The Mediterranean has become excessively dangerous to cross, leading many commentators to call this maritime space a ‘massive graveyard’. The widespread indifference and enmity towards migrants in Europe is, amongst other things, countered by documentary and commemorative projects by artists drawing attention to the suffering of drowned refugees. In this paper, I zoom in on documentary and memorial artistic projects by Mimmo Paladino, Jason deCaires Taylor, Christoph Büchel, Ai Weiwei and Đỉnh Q. Lê. In the frequent absence of dead bodies and specific grave sites on the ‘high seas’, they make claims regarding the humanity, singularity and memorability of the human lives of refugees drowned at sea. Based on a description of the artworks and their public, I make two interlinked theoretical arguments. First, the commemorative materialisations by contemporary artists are temporal claims to constitute the cultural heritage of the future. Second, given the sea’s aquatic materiality, the commemorative claims of these art projects require that commemorative materialisations must spatially move from the flux of the sea to the fixity of the land.
The United Nations Convention on the Law of the Sea contains only general rules concerning the delimitation of the exclusive economic zone and the continental shelf. However, international courts and tribunals have, within their compass, elaborated the law of maritime delimitation through their jurisprudence, thereby maintaining the resilience of the Convention in a particular context of maritime delimitations. The jurisprudence is not a panacea, however. As regards the implications of maritime delimitation judgments for third States in the same region, for example, the jurisprudence has not been consistent. Lack of consistency of the jurisprudence may undermine the predictability of the law of maritime delimitation and weaken the resilience of the Convention. This article critically assesses the approach of the International Court of Justice to the presence of third States in the process of maritime delimitation, by analysing the Nicaragua v. Colombia case and the Costa Rica v. Nicaragua case, respectively.
The decarbonisation of shipping has become a high priority on the environmental and political agenda. The prospect of implementing an Emissions Trading System (ETS) for shipping has come to prominence as a proposed mechanism for speeding up the decarbonisation of the industry, with the EU taking proactive action to include shipping within the EU ETS by 2023. This paper analyses and provides a qualitative review of the historical development of the discussions and actions taken at both global level (by the International Maritime Organization (IMO)) and at regional level within the EU. A SWOT analysis of the potential implementation of an ETS for shipping is then presented. The paper concludes that an ETS for shipping can incentivise greater investment in, and deployment of, green technologies that will have the effect of reducing the carbon footprint of the shipping industry. However, the speed and significance of this effect will depend upon the specific shipping market segment and the relative stage in shipping market cycles over time. It is further concluded that despite the imminent unilateral introduction of shipping into the EU ETS, it is important that the IMO continues its work to develop a global ETS that promotes a ‘level playing field’ for competition within the sector and eliminates the risk of carbon leakage.
