• ¿Riesgo de mareas negras procedentes del mar abierto?

  A. Esparza, X. Osés

  Puertos (2011). Vol. 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 pretende evidenciar dónde pueden ubicarse las áreas del Mediterráneo Occidental español con mayor riesgo potencial de marea negra procedente de derrames de hidrocarburos.

• Improvement of the Energy Efficiency of Vessels as a Measure for the Reduction of Greenhouse Gases Emission from Sea Shipping

  M. Sin, X. Osés

  Journal of marine technology and environment (2011). Vol. 1 (4), pp. 103-112

  
  

  Abstract

  This paper describes how pollution is a serious problem that currently affects many areas of society. Maritime transport is responsible for part of that pollution and measures need to be taken in the logistics of the maritime transport field to reduce ship emissions. Air pollution is not the only problem, greenhouse gas emissions are also a major factor. This paper attempts to do a quick view of the last measures taken by the International Maritime Organization (IMO) in order to reduce greenhouse gas emissions of shipping. An energy efficiency index for ships was created by the Marine Environment Protection Committee (MEPC) to improve the energy efficiency and fuel consumption for ships. This index was developed in voluntary interim guidelines established in the last session of the MEPC during 2009 and 2010, and can be applied to both new designs and ships in operation. For now it is just a voluntary measure that whatever ship-owner could take and verify, but until its approval comes there are no sanctions.

• A study of the riskiest points in front of an oil slick due to an accident in the spanish mediterranean coast

  X. Osés, A. Esperanza

  Journal of maritime research (2010). Vol. 7 (3), pp. 71-82

  
  

  Abstract

  Pollution from shipping traffic poses a real risk to the Spanish coast. Memories of the Fedra bulk disaster in the Strait of Gibraltar, the Prestige sinking in Finisterre or the Castor near accident off Almeria coast are still fresh. The main objective of this paper is to analyse, identify and quantify the Spanish Mediterranean coastal areas where spills from tankers are most likely to occur. The article is based on a study which uses a set of variables such as geographical peculiarities, climate, ship age and traffic density to feed and algorithm. This objective function weighs these parameters all along the coast and identifies the Spanish coastal areas having the highest risk of spills.

• The ecobono: a proposal based on external costs savings

  X. Osés, M. Castells

  Journal of marine technology and environment (2009). Vol. 2, pp. 131-138

  
  

  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% (metric tonnes) between 2000 and 2020. If we consider that the overall expected increase in both freight exchanges and volume is 50%, sea transport appears as one of the most feasible options to reduce traffic congestion on European roads. However, this alternative has not been definitely adopted because of technical, administrative and legal reasons. Moreover, society still regards maritime transport as a slow, inefficient mode since shippers do not yet offer the best value for money. Infrastructures need to be balanced by using tariff principles which reflect the exact external costs incurred by these infrastructures. Along this line of action, in 1998 the European Union published the White Paper on Fair Payment for Infrastructure Use: A Phased Approach to a Common Transport Infrastructure Charging Framework in the EU COM (1998) 466. This paper will conclude proposing an environmental bonus based on external cost savings associated with the use of the short sea alternative instead of road-only transport

• The external costs of speed at sea: An analysis based on selected short sea shipping routes

  X. Osés, M. Castells

  Journal of Maritime Affairs (2009). Vol. 8 (1), pp. 25-43

  
  

  Abstract

  According to the mid-term review of the EUWhite Paper on Transport, Short Sea Shipping (SSS) is expected to grow at a rate of 59%(metric tonnes) between 2000 and 2020. If we consider that the overall expected increase in both freight exchanges and volume is 50%, sea transport is one of themost feasible alternatives to reduce traffic congestion on European roads. Maritime transportation may compete with road transport as far as certain traffics are concerned, but only when assuming external costs. This paper analyzes several intermodal transport chains involving a sea leg by comparing the effect of pollutant emissions from different ship types and road transport in terms of potential external cost savings.The translation of these emissions into environmental costs shows, for certain conditions, savings in the case of sea transport that would justify the use of an environmental bonus to promote the sea option.

• The external costs of short sea shipping. analysis with selected ships

  X. Osés

  Constata Maritime University annals (2008). Vol. 11 (9), pp. 125-130

  
  

  Abstract

  La profesión del marino, ha sido un arcano nutrido de un altísimo nivel de conocimiento práctico derivado de la propia experiencia, que se ha traducido en doctrina científica en los últimos siglos. De entre la amplia panoplia de conocimientos que recibe el alumno o cadete de náutica, destaca la meteorología náutica y en concreto, conceptos relacionados con la formación y efectos del oleaje y de su generador, el viento. Ambos fenómenos están descritos científicamente en la dinámica de fluidos, pero desde el punto de vista del navegante, se analizan desde una perspectiva muy pragmática. En cualquier caso y en atención al interés que suscita al marino, iniciaremos este artículo con una somera descripción de los efectos del viento, de las variables que definen el oleaje y de cómo se relacionan entre sí, hablaremos de situaciones extremas y terminaremos con unas breves conclusiones.

• Una nueva generación de ayudas a la navegación y de publicaciones náuticas

  X. Osés, J. Lozano, S. Vázquez

  Revista del Instituto de Navegación de España (2007). Vol. 30, pp. 30-40

  
  

  Abstract

  Bajo el concepto de un sistema de información y ayuda a la navegación costera, el presente artículo muestra el desarrollo de una aplicación informática que hace posible visualizar datos hidrográficos, meteorológicos y de publicaciones náuticas que tradicionalmente se publican en papel como los "derroteros". Esta herramienta combina además la visión 3D de la costa y la posibilidad de consultar la información textual, correspondiente a los puntos conspicuos que se pueden observar desde la embarcación, conforme se aproxima a las líneas de costa o a los puertos. El desarrollo consta de una base de datos que actualiza la información a petición del usuario, ya sea vía Internet si se dispone del alcance de conexión necesario, o mediante la señal de posición que recibe el GPS, la cual proporciona las coordenadas al sistema, si éste está instalado a bordo como una base de datos independiente vinculada al sistema de visualización tridimensional

• Selection of short sea shipping transport chains in western Europe based on external factors

  M. Castells, X. Osés

  Revista del Instituto de Navegación de España (2007). Vol. 30, pp. 50-57

  
  

  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 traf-fic 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 lev-els of powered ships, which one is going to be the most efficient in terms of exter-nal costs
