Abstract
This paper presents an overview of stability requirements contained in various safety regulations for inland vessels that coexist in Europe. A range of national, regional and international rules that are presently in force, comprise diverse criteria and use different stability assessment methods. Using typical European inland vessels, the differences between regulations are emphasized through numerical examples, with specific focus on inland container vessels and river cruisers. It is demonstrated that existing deterministic regulations fail to provide sufficient level of safety in a number of relevant cases. Therefore, a probabilistic alternative to present regulations is proposed and discussed. Particular attention is paid to appropriate modelling of ship motions and weather conditions (gusting wind). Este escrito presenta una visión general de los requisitos de estabilidad contenidos en diferentes normas de seguridad para los buques de navegación interior que coexisten en Europa. Una gama de normas nacionales, regionales e internacionales, que son actualmente en vigor, comprenden diversos criterios y utilizan métodos de evaluación de estabilidad diferentes. Si se utilizan típicos buques de navegación interiores europeos, las diferencias entre las normas están subrayadas por ejemplos numéricos, con una atención específica a los buques de contenedor interior y cruceros fluviales. Está demostrado que las normas deterministas existentes dejan de proporcionar un nivel suficiente de seguridad en una serie de casos relevantes. A consecuencia de esto, aquí se propone y se discute una alternativa probabilística a las normas actuales. Se presta una atención particular al modelado adecuado de movimientos de la nave y a las condiciones meteorológicas (ráfagas de viento).
