A “Net-Centric” conduct of navigation and ship management

Following the so-called “Industrial Revolution”, the shipping industry has benefitted from a very extended number of technology innovations. Over time, shipbuilding practices and the equipment of ships have been significantly improved. Furthermore, during the last couple of decades, the continuous improvement and integration- interconnection of electronics systems (the “network-centric” approach), have created a new operating environment for shipping. It is therefore not a coincidence that recent discussions on digitalization and autonomous ships provide a disruptive picture of how this industry may be transformed in the near future. Contemporary sea-going vessels are equipped with various technologically advanced systems and are highly automated. Today, all systems supporting the conduct of navigation and the various information technology (IT) applications related to ship management activities are heavily reliant upon real-time information to safely/effectively fulfil their allocated tasks. The issues of connectivity and interconnection clearly stand out. It is important to assess how navigation will be conducted in the near future. This analysis is based on a qualitative methodology, and its starting point, which also serves as the necessary “literature review”, is to identify and briefly discuss a certain number of technological developments that follow the network-centric architecture and have been recently introduced as equipment appropriate for ships. Next, it will examine how interactive processes and applications, both on the shore side and onboard vessels, can facilitate a safer working environment for seafarers and allow personnel based ashore to have a better understanding of what is happening at sea, as part of explaining the so-called “net-centric” framework of operations. Another important aim is to evaluate these promising technological trends according to their capacity of adoption in order to promote efficient and safe operations within the extended maritime transport domain. An important conclusion is that a net-centric philosophy and associated software applications can truly break down any existing limitations and create a collaborative environment for people and “machines”, including remotely controlled unmanned vessels

Biosignal-Based Driving Skill Classification Using Machine Learning: A Case Study of Maritime Navigation

This work presents a novel approach to detecting stress differences between experts and novices in Situation Awareness (SA) tasks during maritime navigation using one type of wearable sensor, Empatica E4 Wristband. We propose that for a given workload state, the values of biosignal data collected from wearable sensor vary in experts and novices. We describe methods to conduct a designed SA task experiment, and collected the biosignal data on subjects sailing on a 240° view simulator. The biosignal data were analysed by using a machine learning algorithm, a Convolutional Neural Network. The proposed algorithm showed that the biosingal data associated with the experts can be categorized as different from that of the novices, which is in line with the results of NASA Task Load Index (NASA-TLX) rating scores. This study can contribute to the development of a self-training system in maritime navigation in further studies

Methods for enhanced learning using wearable technologies. A study of the maritime sector

Maritime safety is a critical concern due to the potential for serious consequences or accidents for the crew, passengers, environment, and assets resulting from navigation errors or unsafe acts. Traditional training methods face challenges in the rapidly evolving maritime industry, and innovative training methods are being explored. This study explores the use of wearable sensors with biosignal data collection to improve training performance in the maritime sector. Three experiments were conducted progressively to investigate the relationship between navigators' experience levels and biosignal data results, the effects of different training methods on cognitive workload, trainees' stress levels, and their decision-making skills, and the classification of scenario complexity and the biosignal data obtained by the trainees. questionnaire data on stress levels, workload, and user satisfaction of auxiliary training equipment; performance evaluation data on navigational abilities, decision-making skills, and ship-handling abilities; and biosignal data, including electrodermal activity (EDA), body temperature, blood volume pulse (BVP), inter-beat interval (IBI), and heart rate (HR). Several statistical methods and machine-learning algorithms were used in the data analysis. The present dissertation contributes to the advancement of the field of maritime education and training by exploring methods for enhancing learning in complex situations. The use of biosignal data provides insights into the interplay between stress levels and training outcomes in the maritime industry. The proposed conceptual training model underscores the relationship between trainees' stress and safety factors and offers a framework for the development and evaluation of advanced biosignal data-based training systems

Context-based Information Fusion: A survey and discussion

This survey aims to provide a comprehensive status of recent and current research on context-based Information Fusion (IF) systems, tracing back the roots of the original thinking behind the development of the concept of \u201ccontext\u201d. It shows how its fortune in the distributed computing world eventually permeated in the world of IF, discussing the current strategies and techniques, and hinting possible future trends. IF processes can represent context at different levels (structural and physical constraints of the scenario, a priori known operational rules between entities and environment, dynamic relationships modelled to interpret the system output, etc.). In addition to the survey, several novel context exploitation dynamics and architectural aspects peculiar to the fusion domain are presented and discussed

Integrated satellite-terrestrial connectivity for autonomous ships:Survey and future research directions

An autonomous vessel uses multiple different radio technologies such as satellites, mobile networks and dedicated narrowband systems, to connect to other ships, services, and the remote operations center (ROC). In-ship communication is mainly implemented with wired technologies but also wireless links can be used. In this survey paper, we provide a short overview of autonomous and remote-controlled systems. This paper reviews 5G-related standardization in the maritime domain, covering main use cases and both the role of autonomous ships and that of people onboard. We discuss the concept of a connectivity manager, an intelligent entity that manages complex set of technologies, integrating satellite and terrestrial technologies together, ensuring robust in-ship connections and ship-to-outside connections in any environment. This survey paper describes the architecture and functionalities of connectivity management required for an autonomous ship to be able to operate globally. As a specific case example, we have implemented a research environment consisting of ship simulators with connectivity components. Our simulation results on the effects of delays to collision avoidance confirm the role of reliable connectivity for safety. Finally, we outline future research directions for autonomous ship connectivity research, providing ideas for further work

P-8 and the Trilateral Partnership. The operational significance and influence on Norwegian security policy

The background for and the strategic context of this thesis is the threat posed by Russian submarines to Norway and NATO in the North Atlantic. In light of this, the study examines the significance of the P-8 and the trilateral partnership of Norway, the United Kingdom and the United States, by asking two research questions: - What is the operational significance of the P-8 and the trilateral partnership? - How does the P-8 and the trilateral partnership influence Norwegian security policy? It is an explorative and inductive study, which answers the research questions through a qualitative analysis. The thesis uses deterrence, crisis stability and maritime airpower theory, as well as Norwegian Security policy and defence concept, with emphasis on integration and reassurance to frame the discussion. The thesis concludes that the P-8 will provide Norwegian decision-makers with an agile platform with significantly improved capability for ASW and ISR. The trilateral partnership integrates the three partner nations and improves NATOs ASW capability when facing Russian submarines in the North Atlantic. The P-8 and the partnership influence deterrence positively by integrating Norway, NATO and the US, and provide tools for improving crisis stability. However, given the impermanency of American Poseidons, there is a need to establish a trilateral P-8 concept that merges training, exorcises and operations as a signal of presence and integration in the North Atlantic. The contribution of the P-8 in Norway’s policy of reassuring Russia is important as Norway increasingly develops a force structure with so-called offensive strategic capabilities. Of particular importance to reassurance is enhancements in intelligence contributions. Provided the strategic context, improved capabilities and the Norwegian force structure, the influence of the P-8 is decisive for the Norwegian security policy.Bakgrunnen for denne oppgaven og den strategiske konteksten er trusselen Russiske ubåter utgjør for Norge og NATO i Nord-Atlanteren. I lys av dette undersøker oppgaven betydningen av P-8 og trilateralt samarbeidet mellom Norge, Storbritannia og USA, gjennom å stille to forskningsspørsmål: - Hva er den operative betydningen av P-8 og det trilaterale partnerskapet? - Hvordan påvirker P-8 og det trilaterale partnerskapet norsk sikkerhetspolitikk? Studien er eksplorativ og induktiv, og benytter kvalitativ metode for å besvare forskningsspørsmålene. Analysen nyttiggjør teorier for avskrekking, krisestabilitet og maritim luftmakt, i tillegg til norsk sikkerhetspolitikk med vekt på integrasjon og beroligelse, som rammeverk for diskusjonen. Oppgaven konkluderer med at P-8 vil tilføre norske beslutningstakere en fleksibel plattform som i betydelig grad bedrer evnen til anti-ubåt krigføring (ASW) og informasjonsinnhenting (ISR). Det trilaterale samarbeidet integrerer de tre partnernasjonene og bedrer NATOs evne til ASW i møte med russiske ubåter. P-8 og det trilaterale partnerskapet påvirker avskrekking positivt gjennom integrering av Norge, NATO og USA, og tilbyr muligheter for å bedre krisestabiliteten. På en annen side er det forventet at amerikansk tilstedeværelse med P-8 vil være av en mindre permanent karakter. Dette medfører et behov for et trilateralt P-8 konsept som sammenslår trening, øvelser og operasjoner i Nord-Atlanteren. P-8s bidrag innen beroligelse er av sentral karakter, ettersom Norge i økende grad satser på avskrekkende kapabiliteter i styrkestrukturen. Spesielt viktig er økt kapasitet innen etterretningsbidragene. Med utgangspunkt i den strategiske konteksten, forbedrede kapabiliteter og den norske styrkestrukturen, er innflytelsen til maritime patruljefly av avgjørende betydning for norsk sikkerhetspolitik

Knowledge Acquisition Analytical Games: games for cognitive systems design

Knowledge discovery from data and knowledge acquisition from experts are steps of paramount importance when designing cognitive systems. The literature discusses extensively on the issues related to current knowledge acquisition techniques. In this doctoral work we explore the use of gaming approaches as a knowledge acquisition tools, capitalising on aspects such as engagement, ease of use and ability to access tacit knowledge. More specifically, we explore the use of analytical games for this purpose. Analytical game for decision making is not a new class of games, but rather a set of platform independent simulation games, designed not for entertainment, whose main purpose is research on decision-making, either in its complete dynamic cycle or a portion of it (i.e. Situational Awareness). Moreover, the work focuses on the use of analytical games as knowledge acquisition tools. To this end, the Knowledge Acquisition Analytical Game (K2AG) method is introduced. K2AG is an innovative game framework for supporting the knowledge acquisition task. The framework introduced in this doctoral work was born as a generalisation of the Reliability Game, which on turn was inspired by the Risk Game. More specifically, K2AGs aim at collecting information and knowledge to be used in the design of cognitive systems and their algorithms. The two main aspects that characterise those games are the use of knowledge cards to render information and meta-information to the players and the use of an innovative data gathering method that takes advantage of geometrical features of simple shapes (e.g. a triangle) to easily collect players\u2019 beliefs. These beliefs can be mapped to subjective probabilities or masses (in evidence theory framework) and used for algorithm design purposes. However, K2AGs might use also different means of conveying information to the players and to collect data. Part of the work has been devoted to a detailed articulation of the design cycle of K2AGs. More specifically, van der Zee\u2019s simulation gaming design framework has been extended in order to account for the fact that the design cycle steps should be modified to include the different kinds of models that characterise the design of simulation games and simulations in general, namely a conceptual model (platform independent), a design model (platform independent) and one or more implementation models (platform dependent). In addition, the processes that lead from one model to the other have been mapped to design phases of analytical wargaming. Aspects of game validation and player experience evaluation have been addressed in this work. Therefore, based on the literature a set of validation criteria for K2AG has been proposed and a player experience questionnaire for K2AGs has been developed. This questionnaire extends work proposed in the literature, but a validation has not been possible at the time of writing. Finally, two instantiations of the K2AG framework, namely the Reliability Game and the MARISA Game, have been designed and analysed in details to validate the approach and show its potentialities

A critical analysis of security vulnerabilities and countermeasures in a smart ship system

It is timely to raise cyber security awareness while attacks on maritime infrastructure have not yet gained critical momentum. This paper analyses vulnerabilities in existing shipborne systems and a range of measures to protect them. It discusses Information Technology network flaws, describes issues with Industrial Control Systems, and lays out major weaknesses in the Automated Identification System, Electronic Chart Display Information System and Very Small Aperture Terminals. The countermeasures relate to the concept of “Defence-in-depth”, and describe procedural and technical solutions. The maritime sector is interconnected and exposed to cyber threats. Internet satellite connections are feasible and omnipresent on vessels, offshore platforms and even submarines. It enables services that are critical for safety and rescue operations, navigation and communication in a physically remote environment. Remote control of processes and machinery brings benefits for safety and efficiency and commercial pressure drives the development and adaptation of new technologies. These advancements include sensor fusion, augmented reality and artificial intelligence and will lead the way to the paradigm of “smart” shipping. Forecasts suggest unmanned, autonomous ships in international waters by 2035. This paper is the starting point for future research, to help mapping out the risks and protect the maritime community from cyber threats
