Hoteling cruise ship's power requirements for high voltage shore connection installations

The main objective of this paper is the presentation of a theoretical and quantitative study of the power requirements that any port considering to install and develop shore to ship connection systems must consider. Particularly, the current study focuses these requirements for cruise ship ports and their terminals. This paper provides theoretical and quantitative tools and ideas that can be used to estimate main design parameters such as frequency, voltage and power for high voltage shore connections. Some models and equations are developed aiming to be able to estimate, with acceptable quality, cruise ship’s power demand for hoteling services at port. On the other hand, this article is intended to assess ship's air pollution impact populated harbour areas to decide whether alternative power supply measures are feasible. Finally, the assessment model is applied at Barcelona's cruise piers and case study is discussed. As a result of that, a daily power demand curve and the consequent air pollution study at the most crowded situation in this port are obtained.Postprint (published version

Cartografía de susceptibilidad hídrica en el delta del río Paraná

The Paraná River delta plays a key role in the economies, water resources, agriculture and social field of the region. A water susceptibility mapping of the region could be a useful tool for the decision making in the agriculture and forestry fields. In addition to the flow forecasts, an estimation of the spatial distribution of the flooding areas according to the predicted hydrologic scenario is very important. The hydrologic scenarios range from very dry (very low water) to very humid (very high water). A water susceptibility map for the mid Paraná River delta was generated using high resolution images from 1980 to 2010 time series, which were processed and classified. This resulting information can be overlapped with the topographic maps of the region and through the geographic coordinate location a field producer or another entity could be aware of the degree of damage by water that a certain area could sufferEl delta del río Paraná es un ecosistema de alta fragilidad ambiental y muy susceptible a las inundaciones. A su vez, se caracteriza por tener una importante actividad económica, social y productiva. Disponer de una cartografía de susceptibilidad hídrica en la región es una herramienta útil para la toma de decisiones en los sectores agropecuario y forestal. Además de los pronósticos de caudales, es importante contar con una estimación de la distribución espacial de los derrames según el escenario hidrológico previsto que puede fluctuar entre muy seco (aguas muy bajas) y muy húmedo (aguas muy altas). Mediante el procesamiento y clasificación de imágenes satelitales de alta resolución correspondientes a la serie temporal 1980-2010 se generó un mapa de susceptibilidad hídrica en el tramo medio del delta Paranaense. El empleo de esta información superpuesta con las cartas topográficas de la zona permitirá al productor agropecuario, a través de la ubicación por coordenadas geográficas, tener conocimiento del grado de afectación por el agua que tendrá un área determinad
