    The booming aviation sector is worldwide increasingly faced with capacityconstraints at both the land and air side. In recent years various countries have tried toovercome the land-based bottlenecks by the design and construction of new offshoreairports. This paper aims to identify and assess the critical success factors for tworecently built island airports, viz. in Hong Kong and Osaka. The analysis addressessuccess conditions at both the corporate and the regional level. The methodologicalbasis for the comparative investigation deploys the so-called pentagon prism. Theresults show that island airports may seem to offer a favorable land use andenvironmental solution, but face at the same time severe financial and maritimeecology problems

    Poseidon: A marine environmental monitoring, forecasting and information system for the Greek seas

    Get PDF
    The scope of this work is twofold: i) to discuss and analyze some principles, issues and problems related to the development and advancement of Operational Oceanography in Greece and ii) to present a real-time monitoring and forecasting system for the Aegean Sea, which is currently under implementation. Operational Oceanography in Greece has become a necessity today, since it can provide aid to find solutions on problems related to societal, economic, environmental and scientific issues. Most of the Greek coastal regions are under pressure, susceptible to damages due to the increasing tendency of the population to move from the inland to the coast, marine environmental pollution, competitive development of the coastal market sector, etc. Moreover, the complex geomorphology of the coastal areas and the interdependence between natural processes and human activities causes significant alterations in this delicate environment. A rational treatment of these problems can be based on integrated coastal zone management (ICZM). An absolutely necessary means for establishing ICZM is the operation of marine moni- toring systems. Such a system ("POSEIDON system") is under implementation by the National Centre for Marine Research. POSEIDON is a comprehensive marine monitoring and forecasting system, that aims to improve environmental surveillance and facilitate sea transport, rescue and safety of life at sea, fishing and aquaculture, protection of the marine ecosystem, etc. POSEIDON is expected to enhance considerably the capabilities to manage, protect and develop the marine resources of the Greek Seas and to promote Greek Operational Oceanography

The European Commission is not responsible for any use that may be made of the information it contains.Deception Island volcano (Antarctica) is one of the most closely monitored and studied volcanoes on the region. In January 2005, a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters. We performed this experiment from aboard the Spanish oceanographic vessel 'Hesperides', and from five land-based locations on Deception Island (the Spanish scientific Antarctic base 'Gabriel de Castilla' and four temporary camps). This experiment allowed us to record active seismic signals using a large network of seismic stations that were deployed both on land and on the seafloor. In addition, other geophysical data were acquired, including bathymetric high precision multi-beam data, and gravimetric and magnetic profiles. To date, the seismic and bathymetric data have been analysed but the magnetic and gravimetric data have not. We provide P-wave arrival-time picks and seismic tomography results in velocity and attenuation. In this manuscript, we describe the main characteristics of the experiment, the instruments, the data, and the repositories from which data and information can be obtained.MINECO/FEDER TEC2015-68752-RKNOWAVESSpanish Education and Research Ministry REN 2001-3833 CGL2005-05789-C02-02/ANT POL2006-08663 CGL2008-01660National Science Foundation (NSF) ANT-0230094 NSF-1521855European project MED-SUV - European Union's Seventh Framework Program 308665European project EPOSEuropean Union (EU) 67656

    Investigating the problems of Indonesian Sea Transportation for an Integrated Information System

    The problems of Indonesian sea transportation are seriously need to reveal and solve. Eventhough, the government has a significant role managing the organisation at the executive, managerial, and operational level. They are needed performing of regulations, strategic policy, law arrangements, data and information management, company culture, business process supervision, and functional activities on-the-spot. This research used a system improvement objective that is causal effect analyses, system objectives, and constraints. The data are collected through document studies, interviews, meetings, and discussions. The confirmation and verifications of models were conducted using Focus Group Discussion. The results of analysis indicate that three main problems are structural organisation (executive, management, and operational level), regulations, and integrated of information system. Based on Critical Success Factors, the main barriers were regulations, policies, political will, bureaucracy, organisational governance, infrastructure, and an integrated system. Specifically, the model of value chain and an integrated of information system architecture are recommended

    Using Automatic Identification System Data in Vessel Route Prediction and Seaport Operations

    Get PDF
    In this paper, the authors perform a comprehensive literature review on the use of data obtained from the Automatic Identification System, with an emphasis on vessel route prediction and seaport operations. The usage of Automatic Identification System vessel’s position data in the vessel route prediction and seaport operations has been analyzed, to prove that Automatic Identification System data has a large potential to improve the efficiency of maritime transport. The authors concluded that proper vessel route prediction and route planning can improve voyage safety and reduce unnecessary costs. Furthermore, AIS can provide port authorities with early warnings, allowing them to take preemptive action to avoid possible congestions and unnecessary costs

    Past, present, and future perspectives of telemedical assistance at sea: a systematic review

    Get PDF
    Background: Telemedicine is an effective technology for evaluating, diagnosing, treating, and providing health care services for remote populations, including seafarers, in case of diseases or accidents on board. Delivery of telemedicine in a maritime environment is not an easy task and, in general, differs from what can be done onshore. The aim of this review is to provides an overview of Telemedical Maritime Assistance Services (TMAS) in Europe by describing the previous and current status in terms of communication technologies as well as the nature of services rendered at sea. Secondly, to discuss the areas needing improvement and future directions to improve the quality of offshore telemedicine services. Materials and methods: Different databases, including PubMed (Medline), Google Scholar, Scopus, and journal of International Maritime Health, were searched between August 1 and September 15, 2019. Articles only published from 1969 to 2019 were considered. Relevant articles were selected by reviewing keywords, titles, and abstracts initially based on our inclusion and exclusion criteria. We critically reviewed the full-text articles included in this review. Information on the means of communication, telemedicine services, years of publication, and the name of the first author was extracted from selected studies. The quality of the selected studies was assessed using the criteria of the Newcastle-Ottawa scale. Results: Initially, 135 articles were identified through searching various databases by using keywords, abstracts, and titles. After removing the duplicates, 121 articles remained. Then we performed an independent article assessment and selection based on the selection criteria, which removed an additional 61 studies, leaving 60 papers. Finally, 27 full-text papers left, and we critically reviewed it. In 27 accepted articles, email and telephone were used most often and accounted for 30% (17/57) and 28% (16/57) of all communication links, respectively. Teleconsultation was the most used telemedicine service on board and represented 58.6% (17/29) of accepted papers. Conclusions: Email and telephone were the principal means of TMAS doctors to provide medical advice as well as assistance for patients at sea. Despite the potential offered by technological progress, there are still many limitations to the provision of adequate medical care at sea. The modernisation of telemedicine services will help decrease the gap in healthcare delivery at sea
