• Incidencia de la altura de las olas en las rutas de navegación de corta distancia en el Mediterráneo

  X. Osés, M. Castells

  Tethys: Journal of Weather and Climate of the Western Mediterranean (2006). Vol. 3, pp. 3-9

  
  

  Abstract

  Según la reciente reseña de medio plazo del libro blanco de la UE sobre el transporte, se espera que la navegación de corta distancia en aguas de la UE crezca del 2000 al 2020 en un 59% en volumen (toneladas métricas). Si tenemos en cuenta que el crecimiento global esperado en intercambios de carga es de un 50% (también en volumen), el transporte marítimo es uno de los medios más factibles para reducir la congestión de tráfico en las rutas europeas. Los barcos de alta velocidad son posiblemente un medio que puede competir con los transportes de carretera en algunos determinados tránsitos; sin embargo, estos barcos se ven afectados por el tiempoi nclemente. Este documento analizará la influencia del tiempo en algunas rutas de navegación mediterráneas de corta distancia recorridas por barcos rápidos.

• Brief analysis on the generated residues coming from oil sea transport in Spain

  X. Osés

  Revista del Instituto de Navegación de España (2007). Vol. 28, pp. 44-57

  
  

  Abstract

  Around 1.500 to 1.800 million tonnes of crude oil and over 400 to 500 millions of tonnes of refined oils ; are transported across the sea every year on board tanker ships. Europe is a great consumer of those commodities, receiving up to 500 millions of crude oil tonnes and around 250 to 300 million of refined products tonne per year. This means that EU needs about 6000 freights per year in order to covr the crude oil demand, carried out by between 155 to 2000 tanker ships. This paper is going to analyse the residues generation coming from such exchanges in the Spanish waters.

• Modelo de formulación para comprender los costes y tiempos de los acarreos terrestres para el reparto de mercancías mediante transporte rodado de mercancías y transporte marítimo de corta distancia

  J. Nuevo, X. Osés

  Revista del Instituto de Navegación de España (2010). Vol. 37, pp. 4-10

  
  

  Abstract

  En el desarrollo del mundo globalizado cada vez resulta de mayor importancia cómo se distribuyen las mercancías desde su origen a su destino. Es cierto que la tendencia y la conciencia tiende a realizar transportes más respetuoso con el medio ambiente y más eficientes. En muchas ocasiones nos encontramos con la ilógica situación de contratar transportes sin un criterio razonado. El propósito de este artículo es plantear la realización de un simulador de costes y tiempos para valorar la posibilidad de llevar a cabo un transporte de mercancías con el modo más acertado, sabiendo de antemano cual será su coste y su precio. Debemos entender que el modo de transporte de carretera es necesario e incluso imprescindible, pero en muchos de los escenarios no es el más conveniente. Planteamos por tanto, la realización de un transporte multimodal e incorporar en el mismo el TMCD (Transporte Marítimo de Corta Distancia)

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

  X. Osés, A. Esparza

  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 carrier 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 based on a study which uses a set of variables such as geographical peculiarlities, climate, ship age and traffic density to feed an algorithm. This objective function weighs these parameters all along the coast and identifies the Spanish coastal areas having the highest risk of spills.

• Cost assessment simulator for transport between mediterranean Spanish ports and the Black Sea

  X. Osés, M. Castells, M. Rodríguez

  Journal of Maritime Research (2013). Vol. 10 (1), pp. 31-38

  
  

  Abstract

  There is a strong imbalance in EU transport mode shares. In addition, issues like road traffic, noise, accident rates, and especially polluting emissions result not only in external costs to society, but also in high logistical costs to transport service customers. The present paper proposes an assessment model to evaluate final internal and external costs of transport chains served by trucks and short sea shipping (SSS). An efficient and fast tool is presented to help customers decide on the most convenient mode of transportation for a specific trade link. The trade links in this paper connect 19 Spanish provinces to the main ports in the Black Sea region (Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine) through the ports of Barcelona and Valencia.

• Analysis of viability to promote a hub ro/ro terminal in Palma of Mallorca (Spain) port

  X. Osés, I. Galiano

  Journal of Maritime Research (2014). Vol. 11 (E2), pp. 33-39

  
  

  Abstract

  The presented paper is going to analyze the opportunity to develop a Ro/Ro hub in the Port of Palma de Mallorca. In order to get introduced in the study, the state of art related to geographical, economic traffic and human; conditions, will be reviewed: together with an in deep analysis of the port future capacities and main shipping lines crossing the western Mediterranean. At a first glance is it easy to understand that the competition with other container hub ports in Mediterranean does not afford Palma de Mallorca to be positioned in this market. But the chance to become a hub in rolled traffic will be studied.  The final results of this paper are going to identify the main particulars to be enforced to attract the main shipping companies are providing transport services between the North and South coasts of the Mediterranean and the traffic between Italy and Spain.

• The Exploration, Development and Perspective of Oil And Gas in The Black Sea Region

  X. Osés, S. Mihailovici

  Journal of Maritime Research (2015). Vol. 12 (3), pp. 49-56

  
  

  Abstract

  The Black Sea region, a large horizon ready to open, ready to explore, ready to show her energy, her power and opportunities. But how we are preparing for this?. It is a high compettiton between all the actors implicated in this field. The industry was informed to this potential resources by a major study undertaken by Purvin and Gertz in 2011, which predicted a development of a Romanian offshore industry and now exist many recently studies that confirmed the resources of the Black Sea. We all nnow about the emergence of shale gas in europe, in the last years because is increasing evidence os a more united approach on energy, so the exploration and development of gas reserves in the Black Sea is an optimal alternative to supply gas from the Caspian to South-Eastern Europe. But this good alternative implicates problems generated by costs, transportation and security of the very long pipelines that will pass through several countries till reaching their final destination. We try in this paper to pay attention on the main objective in the Black Sea region, in this offshore field, that required the cooperation and sustainability from part of European Union and all its members' state and countries situated in the Black Sea, Mediterranean Sea or Caspian Sea.

• A Ship Routing System Applied at Short Sea Distances

  M. Grifoll, X. Osés

  Journal of Maritime Research (2016). Vol. 13 (2), pp. 3-6

  
  

  Abstract

  New generation of high-resolution meteo-oceanographic predictions provides useful tools for routing of ships in short maritime distances. In this work, the optimal ship routing analysis is investigated in maritime routes in the Western Mediterranean Sea for relative short sea distances. A* algorithm is implemented in order to obtain the optimal path under an energetic wave events. The methodological aspects are presented including the grid description and weather prediction systems. The optimized cost function is the travel time and it is obtained considering the added resistance due to waves. A practical example considers the maritime route between Barcelona and Algiers. The results show the influence of this factor in the optimum path recovered by the algorithm. The relevance of the relative direction between wave and ship route is proven comparing the ship routing results.

• Alternative Manoeuvres to Reduce Ship Scour

  M. Castells, A. Mujal-Colilles, A. Llull, X. Gironella, X. Osés

  Journal of Navigation (2020). Published online

  
  

  Abstract

  Scouring and sedimentation effects on the seabed induced by ship propellers during ship manoeuvring near harbour structures affect both structure stability and ship manoeuvring capabilities. This contribution proposes solutions at an operational level using the automatic identification system (AIS) and a bridge simulator. Two new alternative manoeuvres were designed and tested on a bridge simulator to obtain expected maximum scour depth and the results were compared with that of real manoeuvres (i) using mooring lines, and (ii) with tug assistance. A total of 42 test scenarios combining several manoeuvres and meteorological conditions were reproduced. Results confirmed a clear reduction in erosion depth with the alternative manoeuvres, with total reduction when using the tugboat. The presented methodology can be very useful to port authorities to prevent the effects of ship erosion on harbour infrastructures.
