17:30 - 18:00Resumen del trabajo
Aunque el transporte por trenes de empuje en navegación interior no es nuevo, sí puede considerarse como un tipo especial de buque. En los últimos años, la creciente importancia de su capacidad logística, su flexibilidad ante diversos escenarios hidromorfológicos y, sobre todo, su bajísima huella ambiental por tonelada-kilómetro, han incrementado la atención sobre las variables y el control de parámetros en la gestión de flotas modernas. Solo en América y Europa se movilizan cerca de 1.200 millones de toneladas de carga al año mediante este sistema. Esta relevancia logística exige considerar configuraciones de trenes más grandes y potentes, estableciendo parámetros técnicos claros para optimizar la eficiencia y ofrecer una base de referencia sólida que las autoridades marítimas están solicitando con interés. Estas formaciones deben contar con gran capacidad de maniobra y tiempos de reacción mínimos comparados con los buques de ultramar, además de un alto grado de variabilidad en la potencia aplicada a lo largo de su travesía. En este contexto, el estudio analiza formaciones típicas de trenes de barcazas en distintos escenarios hidromorfológicos, comparando las potencias efectivas requeridas mediante herramientas teóricas, especialmente el análisis CFD (Computational Fluid Dynamics).
Although pushing convoys for inland navigation is not new, they can be considered a special type of vessel. In recent years, the growing importance of their logistical capacity, their flexibility in various hydromorphological scenarios, and above all, their very low environmental footprint per ton-kilometer, have increased attention to variables and parameter control in modern fleet management. In both the Americas and Europe, nearly 1.2 billion tons of cargo are transported annually using this system. This logistical relevance requires considering larger and more powerful train configurations, establishing clear technical parameters to optimize efficiency, and providing a solid reference base that maritime authorities are showing interest in. These formations must have great maneuverability and minimal reaction times compared to ocean-going vessels, as well as a high degree of variability in power applied throughout their voyages. In this context, the study analyzes typical formations of pushing in different hydromorphological scenarios, comparing the effective power required using theoretical tools, especially CFD (Computational Fluid Dynamics) analysis.
