• Is the utilization of methane gas the solution to air pollution in diffuse sectors? The case of Port of Castellón

  X. Osés, J. Aizpuru

  International Journal for Traffic and Transport Engineering (2011). Vol. 1 (4), pp. 206-213

  
  

  Abstract

  Considering environmental regulations, imposed by an international regulation body restricting the emission levels from ships in ports, with even more stringent local regulations envisaged, the challenges for the world’s fleet are not only technical but economic and logistical. On the one hand, there are different technical alternatives enabling the current international regulations to be met. Even avoiding on board modifications,the owner can decide to use low sulphur content fuels, together with slight changes in engines to reduce the levels of nitrogen oxides. But the question posed in this paper is how to support the decision to use high quality oil derivatives, bearing in mind environmental considerations, but with a favourable economic balance. That enormous cost will be translated into a higher transport chain cost. Additionally, regarding coastal navigation, it might become possible for some new regulations to penalize elevated rates of CO2 emissions, not yet considered by the MARPOL convention. This paper analyzes the availability of the use of methane as an ideal fuel which meets the nowadays and even future, local and international regulations on CO2 and NOx, regarding the fuel derivatives and no emissions of sulphur oxides and ashes.

• Port-City Closeness and Turnaround Time Critical for Short Sea Shipping Sustainable Performance a Case Study: Spain

  U. Santamaría, M. Castells, X. Osés

  International Journal for Traffic and Transport Engineering (2011). Vol. 1 (3), pp. 168-179

  
  

  Abstract

  Air pollution is the most relevant externality of maritime transport and its effects are more acute in urban areas. As Short Sea Shipping (SSS) services call ports frequently and expend significant time in port, both the overall turnaround time and the port city closeness, become critical in their sustainable performance. This paper analyses the impact of maritime transport on Spanish SSS ports and identifies the ideal ones, reflecting the differences in their sustainable performance and finally identifying the characteristics that a harbour needs to gather in order to minimize air pollution impact in the maritime transport sector.

• "e" un nuevo paradigma en la navegación y el transporte marítimo: "electronic-enhanced-environmental"

  X. Osés, S. Velasquez Correa

  Revista del Instituto de Navegación de España (2011). Vol. 39, pp. 24-45

  
  

  Abstract

  En la era digital y de la información, el mundo del transporte marítimo ha tenido que adaptarse al uso de las tecnologías de la sociedad de la información y las comunicaciones, casi todas, “bautizadas” con el sello “e”. Como se irá argumentando, la “e” puede tener un significado según el contexto pero a la postre, permite interpretarse como un elemento integrador que emplea algún atributo de naturaleza electrónica o digital y que se traduce en la adopción de sistemas y servicios más robustos que optimizan el uso de recursos, tiempo y obviamente, costes, en los procedimientos de adquisición, intercambio, visualización, envío y actualización de datos, imprescindibles en cada uno de los ámbitos y procedimientos involucrados en el transporte de mercancías y pasajeros por mar. Mediante este artículo se buscará ubicar a la Industria Marítima Española dentro de estas tendencias y la implantación de conceptos como ventanilla única, interoperabilidad,gestión de los flujos de información y otros más, asociados a una dinámica “estandarizadora” y “armonizada” dentro del contexto europeo del Transporte de Superficie y más concretamente, los corredores marítimos y multimodales que han de 1 conformar lo que se ha denominado “Autopistas del Mar”

• ¿Riesgo de mareas negras procedentes del mar abierto?

  X. Osés, E. Amable

  Puertos (2011). Vol. 28 (159), pp. 49-57

  
  

  Abstract

  El objetivo fundamental de este artículo es el de analizar, identificar y, posteriormente, cuantificar las áreas de la costa Española Mediterránea con mayor riesgo de sufrir un derrame de hidrocarburos procedente del tráfico marítimo de hidrocarburos. En el estudio que fundamenta este artículo se han tomado en consideración una serie de variables de entre las que destacamos las peculiaridades geográficas, climáticas o la densidad de tráfico que alimenten una función aleatoria. Esta función objetiva ponderará los diferentes puntos de la costa e identificará los que tengan una mayor probabilidad de riesgo.  En la investigación aquí presentada se presente evidenciar dónde pueden ubicarse las áreas del Mediterráneo Occidental español con mayor riesgo potencial de marea negra procedente de derrames de hidrocarburos.

• Una propuesta de ecobono español

  X. Osés, M. Castells

  Estudios de Construcción y Transportes (2010). Vol. 112, pp. 7-19

  
  

  Abstract

  El presente estudio, fue financiado en la convocatoria del año 2008 según ORDEN FOM/2219/2008, de 22 de julio (BOE del 29), de subvenciones para la realización de estudios y acciones de difusión relacionados con el transporte, sus infraestructuras y demás competencias del Ministerio de Fomento. El objeto del mismo fue la elaboración de un análisis comparativo entre los costes externos generados por el transporte por carretera y el marítimo en un mismo recorrido. De esta comparativa se dedujo en cada caso una diferencia entre los costes externos producidos por cada modo de transporte. En el caso que esa diferencia en costes externos fuera favorable al transporte marítimo, los autores proponen una subvención a los transportistas que usen el modo marítimo, con un tope igual a ese diferencial citado pro recorrido y camión. Postprint (published version)

• Sustainability of motorways of the sea and fast ships

  X. Osés, M. Castells

  (2009). Marine Navigation and Safety of Sea Transportation, pp. 149-155

  
  

  Abstract

  The European transport policy undertakes to enhance sustainability in transport in order to boost economic activities in the whole EU. The reduction of pollutant emissions and a better balance among modes of transportation to cut road congestion are the pillars of the above policy. These factors are encouraging public and private stakeholders to use the freight maritime alternative more extensively. Short sea shipping is considered the quickest way to reach sustainability. Another advantage of ships over trucks and trains is that vessels consume less fuel as a result of the relatively low speeds at which they travel. However, increasingly faster ships are in a position to compete with trucks, but the former’s greater power demand and consumption rate result in higher pollutant emission levels which, in turn, lead to the loss of their environmental advantage over road transport. This problem is analyzed below.

• Selection of Short sea Shipping Transport Chains in Western Europe, Based on External Costs

  X. Osés, M. Castells

  Journal of Maritime Research (2008). Vol. 5 (3), pp. 43-54

  
  

  Abstract

  According to the mid term review of the EU White Paper on Transport, Short Sea Shipping is expected to grow at a rate of 59% in metric tonnes, from 2000 to 2020. If we consider that the overall expected growth in freight exchanges is of 50% (also in volume), sea transport is one of the most feasible way to reduce traffic congestion on European roads. Marine transport is a possible way to compete with road transport in certain traffics, mainly when assuming external costs. This paper is going to analyse five multimodal routes, considering three different levels of powered ships, which one is going to be the most efficient in terms of external costs.

• Heavy Weather in European Short Sea Shipping: Its Influence on Selected Routes

  X. Osés, M. Castells

  Journal of Navigation (2008). Vol. 61 (1), pp. 165-176

  
  

  Abstract

  According to the mid-term review of the EU White Paper on Transport, short sea shipping is expected to grow at a rate of 59% in metric tonnes, from 2000 to 2020. If we consider that the overall expected growth in freight exchanges is of some 50%, sea transport is one of the most feasible ways to reduce traffic congestion on European roads. High speed vessels are a possible way to compete with road transport on certain routes; however, these ships are highly affected by heavy weather. This paper analyses the weather influence on several short sea shipping routes to be served by fast ships.

• The ICARUS portal: An aid to improve safety of navigation

  X. Osés, S. Velasquez

  Journal of Maritime Research (2006). Vol. 3 (1), pp. 17-26

  
  

  Abstract

  Leisure ships and non SOLAS (International Convention for Safety of Life At Sea) ships as fishing vessels or small tugs, are not subjected to International Maritime Organization (IMO) standards related to the equipment, but by the classification societies through additional requirements related to the control centre physical distribution. The ICARUS concept tries to provide to the end users, a practical tool supplying information from the books collection on board like Pilot books and others as well as meteorological information and weather forecasting, all integrated in an internet portal, accessible from portable devices like the latest generation mobile phones or palms. GPS or positioning systems will make possible to update information and selected screens will display data required by means of a complete menu. Today communication and internet based technologies with the support of GIS technologies have created a very friendly environment. XML and JAVA technologies have been used for the data interchange and software development in the end user´s application.
