“…They are mostly related to the hydrodynamic performance of the vessels and transport efficiency, but not directly to the energy efficiency from an environmental point of view, as in the case of EEDI or EEXI. Proposed energy efficiency indices, in particular, (explored for IWV and EU waterways) have already been systematically presented in [13], while the original research was delivered in [14,15]. There are very few studies available regarding EU waterways but there is a study on this topic for waterways outside the EU, see [16,17].…”

Although the International Maritime Organization (IMO) introduced the energy efficiency requirements for ships more than a decade ago, to date, inland navigation has not been affected by corresponding regulations at all. Therefore, inland waterway vessels are left with no mandatory requirements that could push their technology into more energy efficient design. Fortunately, there are certain pioneering attempts to define energy efficiency criteria for inland vessels. This paper tries to gather and provide a review of such methods. Moreover, a typical Danube cargo inland vessel’s data are used to evaluate their current energy efficiency levels with respect to provisional criteria. Consequently, two methods are found and used here. They are both based on IMO’s energy efficiency concept but modified for the inland waterway vessels. The methods delivered a significant difference in applicability and were difficult to compare. Moreover, shallow and deep-water effects are explored in the same regard but provided unsound conclusions. The final results displayed discrepancies in energy efficiency levels for the same vessels and so the methodology should be improved and harmonised, if it is to be introduced as mandatory for inland waterway vessels. The analysis provided a glimpse into the current condition of the traditional design of the Danube inland fleet, with respect to the emerging energy efficiency policies.

“…At low speeds, the depth of water does not affect the wave pattern, nevertheless, by increasing the vessel speed above that which corresponds to a depth Froude number (Fnh) greater than 0.5, the local pressure distribution around the hull starts being directly affected by the water depth. The theoretical critical speed corresponds to Fnh=1, this speed leads to significant growth of the bow wave and a consequent increase of the wave resistance [8] [9].…”

“…Radojcic et al [9] state that according to ITTC 2017 [10], shallow water effects on vessel resistance should be taken into consideration when either the water depthdraught relationship (h/T) is below 4 or the depth Froude number (Fnh) is higher than 0.5. Given the water depth levels of the Magdalena, most vessels navigating on this river will fulfil at least one of these criteria.…”

Inland waterways are presented both as a need and an opportunity for developing an intermodal transport system to boost Colombian economic growth. Riverine transportation as part of an intermodal system represents conveying a significant amount of cargo at a low cost and therefore reducing greenhouse gas emissions. To competitively include this cargo transportation alternative in an intermodal context, the development of effective container vessels is required. Most of the Colombian rivers present sedimentary, high flow, and low depth nature. Then, the design of riverine cargo vessels capable of navigating in shallow waters with less brake power requirements is needed. A synthesis model: an automatic and integrated design procedure, has been programmed to generate and evaluate feasible vessel dimensions at a conceptual design stage. Through systematic variations of the main dimensions, this procedure allows evaluating a design space in which the most effective concept-vessel solution is selected. At the end of this procedure, the main characteristics for container vessels in the Magdalena River at a conceptual design stage, are defined. Validation of the synthesis model with a riverine logistic support ship is provided.
