ESPOMAR PROJECT: NEW PASSENGER MARITIME TRANSPORT SYSTEM FOR THE GULF OF CÁDIZ (PRELIMINARY RESULTS)
Proceedings of the International Conference Marine Design, 2020
The ESPOmar project is a cooperation research network with the aim of designing and evaluating a new sustainable cross-border maritime transport system for the Gulf of Cadiz. The key objectives of the ESPOmar project are: to analyse the real demand of such a transport system; to study the nautical condition for navigation of the area; to define the capacity and specification of each proposed maritime route; and to optimize the design of specific ferries to compete with the established land transport system in terms of speed, safety, and comfort, reducing emissions and increasing economic viability. Economic viability and local economic impact were key tenets of the evaluation process. This paper presents the preliminary results and conclusions of the evaluation process for the proposed maritime routes examined.
Maritime and river transport and associated infrastructures that are not considered to be the responsibility of the State (i.e. the national Government) are among the various competences of the Regional Government, and specifically of the Consejería de Fomento y Vivienda of the Junta de Andalucía. The Agencia Pública de Puertos de Andalucía (APPA) is an authority under public law, attached to the Consejería, which is concerned with the development and application of policy for ports and matters relating to the areas of transport of the Regional Government of Andalusia. The GuadaMAR project, financed by European Union funds for regional development (FEDER) and by the Government of Andalusia, involves work on various objectives that are essentially aimed at the theoretical design of a Prototype vessel and maritime navigation system for the River Guadalquivir. Based in the port of Seville, this would serve as a transport system for passengers, under criteria of efficiency, technical operability, and economic and environmental sustainability. Presented in this communication are the first advances accomplished, particularly in the design of lines (routes) and in the alternatives studied for the propulsion of the vessels. As the working hypothesis, two possible lines of navigation are being considered: one an external inter-urban line along the main channel of the river, which could link the nearby population centres (Coria, Gelves) to a point in the proximity of the Metro Interchange Station of San Juan de Aznalfarache; and the other an urban line that, in successive phases of expansion of the project, could link intermodal stations on one or other riverbank, with the object of facilitating urban mobility, especially in areas close to the course of the river (Triana, City Centre, San Jerónimo, Recinto ferial, etc.), providing access to Metro/Bus/SEVICI).
A Study into the Development of More Energy Efficient and Less Polluted Fishing Vessel
— The successful application of catamaran hull form as passenger carriers has been well-known since the last 30 years. It is later extended to the development of fishing vessels and the reason behind this is attributed to safety criteria and wider deck-space which can be offered by the catamaran. It is also in connection with the handicaps of monohull fishing vessels, in terms of stability and seakeeping performance which can be improved by the introduction of catamaran forms. Recent situation on the rare and expensive fossil fuels have caused the fishermen into deep trouble hence most of them tend to be deprived if there is no anticipation taken to help them. The current paper describes a systematic investigation into the way to reduce (if not possible to replace completely) the use of fossil fuels on a catamaran fishing vessel. The study is focused on the use of diesel engine, sail and solar power on individual application as well as the combination of them. The implication to the final cost of the vessel, however, is negligible. It is discovered that the use of diesel engine could be replaced by the use of sail and solar power for individual basis. A combination of those power sources is found to be more appropriate in terms of stability and capacity of fishing holds. The investigation is extended to the evaluation of energy efficiency design index (EEDI), a compulsory criterion for measuring marine pollution made by the international maritime organization (IMO) and applied for ocean-going vessels. It is considered for fishing vessels because this type of vessel is thousands in number and most of them use engine together with fossil fuels hence there is strong potency to pollute air and the environment.

Study of the Use of Alternative Energy Sources in Inland Waterway Transport
Transport Problems, 2019
A study has been conducted on the use of alternative energy sources for propulsion of a vessel in inland waterway transport. It is clear that at this stage it is most appropriate to use a vessel designed for short-haul trips between two banks of a ferryboat for passengers and luggage or for recreation and entertainment. On this basis, research has been conducted on a newly designed and built vessel to carry up to 12 people. The drive is fully powered by 180-Ah batteries at 48 V. The batteries are charged by the sun through 5-kW solar panels. The results show that the vessel powered by two 5-kW electric motors can sail autonomously for about 1.5 hours, to travel about 13 km, at an average speed of 7.9 km/h with an average energy consumption of 71.3 kWh/100km when sailing on a linearly reversible route including sailing downstream and upstream on the Danube River.
Design aspects of inland navigation catamarans
Analele Universităţii "Dunărea de Jos" din Galaţi. Fascicula XI, Construcţii navale/ Annals of "Dunărea de Jos" of Galati, Fascicle XI, Shipbuilding, 2016
The paper aims to identify the main aspects in design of catamarans for inland navigation, but not limited to, and to present some approaches related to this aspects. The catamarans have some consistent advantages against conventional monohull: larger deck area, better transverse stability and in general improved behaviour in waves. As consequence the catamarans have gained ground in a wide range of applications: inland/maritime passenger ships, passenger or car/passenger ferries, inland cargo ships and even Navy ships. The main design aspects discussed in this material are: hydrodynamic efficiency, hull and deck structure design, passenger/cargo space arrangement, machinery and installations aspects, intact and damage stability aspects. The methods presented here, related with the above aspects, are based on international ship design and construction rules, results of structure design investigations and towing tank experiments developed in other paperwork.

Numerical simulation of large commercial ship navigation on Paraná river, Argentina
MARINE VII : proceedings of the VII International Conference on Computational Methods in Marine Engineering, 2017
In recent years, the large commercial ships (Post-Panamax) started sailing the Argentinean waterway of the Paraná River. So that, the research project of the FICH-UNL called "Analysis of Hydro-Sedimentological Effects Caused by River Navigation on Argentinean Waterways" decided to use the computational simulation as one of tools research to study the hydraulic and sedimentological effects caused by the navigation of these ships on the morphology of the rivers of the Argentine waterway. One of the premises of this work was to explore the capabilities of the Adapco STAR CCM + CFD code to simulate the ship navigation in calm water in order to measure the heights of waves generated (among others), validating its results with the experimental one (physical model of large ships navigation carried out at the Hydraulics Laboratory of FICH-UNL). Navigation situation simulated: JAPAN Bulk Carrier (JBC; Lpp: 280 m, Bwl: 45 m and D: 25 m) with a service speed of 22 knots (11,3m/s) navigating against a flow stream with velocity of 2m/s (habitual situation of JBC navigation on Paraná River). The numerical modeling reproduced the navigation ship in scale (1/36.7), using a Computational Fluid Dynamics code (CFD) by finite-volume method (VOF). A study of mesh dependence was performed to analyze the convergence model. A mesh of hexahedral cells was used in the Volume of Fluid (VOF) Multiphase Model for waves and dumping waves. The turbulence was modeled by a k-Epsilon model from Reynolds Average. Wave damping was used in the lateral walls of the domain.
Baja , Hungary 1 Improving the efficiency of small inland vessels
2010
On behalf of the Belgian Federal Public Service Mobility and Transport, the Maritime Technology Division of Ghent University had performed a scientific investigation to assess potential technical measures to increase the energy efficiency of inland vessels, and the costs and benefits – including environmental aspects – resulting from these measures. The results of this study can be applied to the design or reconversion of inland vessels to reduce the energy consumption and emission of greenhouse gases and noxious materials. The study consists of a literature study, an analysis of the present inland vessel fleet, and the study of available data concerning resistance and propulsion, to determine measures that can lead to an optimization of the design of an inland vessel by: Reducing the hull resistance; Increasing the hydrodynamic efficiency of the propeller by improving the design and selection of an optimal propeller; Increasing the efficiency of the engine; Any other measures (e.g....

The increase of fuel price has caused fleet operational and shipping business to be in danger situation. The fuel consumption of a ship is influenced by ship volume or wetted area which contributes directly to the increase of ship resistance and the size of main engine. In order to find out the appropriate answers, a series of investigation into river transportation using monohull, catamaran and trimaran types of vessel was carried out. The work focused on the estimation of total resistance and powering as well as seakeeping characteristics and carried out experimentally using tank test and numerically using a ship design software (Maxsurf). It was found out that the catamaran and trimaran could have less resistance and hence power compared to monohull of similar displacement. The seakeeping characteristics of the multihull vessels were also comparable with those of the monohull. This is a good indication that river catamaran/trimaran is an efficient and comfortable vessel. If a prototype or real vessel is developed, it can be a very efficient ship as well as a ship with high safety standard.
Synthesis Model for the Conceptual Design of Inland Cargo Vessels to Operate on the Magdalena River
Brodogradnja
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 solutio...
