Maritime anomaly detection is a key technique in intelligent vessel traffic surveillance systems and implementation of maritime situational awareness. In this paper, we propose method which combines trajectory clustering Naïve Bayes classifier to detect anomalous behaviour the system. A similarity measurement between trajectories designed based on spatial directional characteristics Automatic Identification System (AIS) data, then hierarchical k-medoids are applied model learn typical...

The integration of IT, OT, and human factor elements in maritime assets is critical for their efficient safe operation performance. This defines cyber physical systems involves a number IT OT components, systems, functions that involve multiple diverse communication paths are technologically operationally evolving along with credible security threats. These threats risks as well known breach scenarios described this paper to highlight the evolution domain emerging vulnerabilities. Current...

This paper presents a fuzzy set-based approach to the evaluation of information technology (IT) projects. We assume multi-criteria decision-making framework, where sets general and domain-specific criteria are used judge relative performance alternative technologies. The methodology was originally developed for DIAS.net, an EU project aiming at development Information Society in insular isolated regions Europe. In this paper, we present many aspects our including synthesis teams, assessment...

3D printing or additive manufacturing (AM) (in the industrial context) is an innovative, as opposed to subtractive, technology, bringing new opportunities and benefits spare part supply chain (SPSC). The aim of this work capture views stakeholders at end chain, extruding factors that will benefit end-user are likely be obstacle, by employing questionnaire method. Company objectives regarding spares (cost reductions, improvement services, space reduction) have been prioritized differently...

This paper presents a decision support model that assesses offshore suitability for floating wind turbine installation. The is based on Multi-Criteria Analysis and Geographic Information Systems. An implementation of the Aegean Sea also presented. methodological approach followed consists four stages. first stage excludes sites are inappropriate siting legislative constraints. At second stage, set evaluation criteria used in order to identify most suitable areas Next economic highest-scored...

In an ever-evolving technological industry, the oil and gas sector is already moving forward through adaptation of Industry 4.0 advanced cyber technologies Oil Gas 4.0. As IT/OT (information technology/operational technology) systems are evolving technologically, so security threats faced by offshore assets. This paper aims to raise awareness organizational technical measures that need be adopted industry for remote complex assets in upstream sector. A comprehensive literature review...

This research investigates the potential of additive manufacturing (AM) to revolutionize marine spare parts supply chain (SPSC). While AM has been widely explored in other industries, its application maritime sector remains limited. study addresses this gap by comparing traditional and AM-integrated SPSC models using system dynamics simulation. By focusing on high- low-value parts, highlights significant cost reductions improved delivery times through strategic integration. Our findings...

Marine ports operations are often associated with a variety of externalities, including issues like air pollution and noise, among others; there is clearly negative impact on the working environment quality life citizens living next to port. An effective way improve overall situation can be provided by deploying shore-to-ship electrification method, also known as Cold Ironing. Unfortunately, still disadvantage: no holistic approach involved, external electrical grid usually powered fossil...

Renewable energy sources increase their share in the mix and, therefore it is important to accommodate variability production. In this study, a hybrid approach evaluated where combination of batteries and compressed air are used together with seawater reverse osmosis order match renewable against electricity water needs. Especially remote islands energy-powered desalination an attractive option. These technologies tested on semi-submersible floating platform, accommodating offshore wind...

The paper explores the rationale of embracing e-Governance models as a mean to improve port policy and decision making towards enhanced performance competitiveness.The establishes both significance applicability advanced models, based on e-markets typologies.The devised theoretical framework suggests that within evolving variation structures, e-Governance, public-private interorganisational network in particular e-market paradigm provide great opportunity 'smart networking' plurality actors,...

The presence of sulphur in marine fuel oil relates to health and environmental concerns, as the respective combustion generates dioxide (SO2). only method control this SO2 generation is limit quantity fuel. Shipping activities, although not main source, contribute around 13% total anthropogenic IMO-3GHG [2015. Third IMO Greenhouse Gas Study, 3rd ed. London: International Maritime Organisation]; on a positive note, expected reduce after worldwide implementation 0.5% regulation for One...

Taking advantage of the benefits associated with digital means has become a main priority for ports globally. The effective and smooth integration Information Technology (IT)applications those systems that support conduct operations(Operational (OT)systems), along accurate"adjustment" human factor elements should be viewed as very critical pillar optimized, safe efficient operations in ports.The aforementioned assimilationcharacterizes cyber-physical entails an extended number IT OT modules,...

Shipping companies are high-vulnerability information handling organizations (HIHOs). In the past, such used exclusively HIHO private communication networks and own satellite resources in order to share transport sensitive information. recent years, ability for network users exploit advantages of low-vulnerability organizations’ (LIHOs) value added networks, has led need augmentation networks. maritime sector, a push-and-pull effect on demand transfer onboard ashore many experiment with...

The paper presents a theoretical framework and an empirical examination of the provision port e-services through exploratory research. presented survey examines socio-technical environment in which are developed provided, as well related investment decision making evaluation procedures, Greek sector.
