E-Type self-propelled vessel: A novel concept for the Danube

Abstract

The goal of the present study is to encourage the discussion on the future of the Danube fleet by providing a novel approach to design of self-propelled dry bulk cargo vessels for the Danube. The main dimensions of a standard European CEMT Va class vessel are re-examined in the light of the Danube navigation conditions, characterized by the shallow-water sectors and thus, considerably affected by the low-water periods. As a result, a shallow-draught vessel of increased beam, the so called E-Type, is put for-ward. Given that the proposed design could be regarded as "unusual" by classification societies, the preliminary design study is followed by a thorough analysis of structural strength, with particular emphasis on the longitudinal strength issues. The study is complemented by an assessment of energy efficiency of the novel concept. It is believed that the proposed E-Type concept could represent a viable, cost-effective and environmentally-friendly solution for the present navigation conditions on the Danube.
