La dinámica de fluidos computacional (CFD) se ha convertido hoy en día en una herramienta importante en el proceso de diseño hidrodinámico de los buques modernos. El CFD se utiliza para modelar cualquier fenómeno relacionado con el flujo de fluidos en un volumen de control como un buque o cualquier estructura offshore en el mar. En el presente estudio se estiman los coeficientes de arrastre generados por la fuerza inducida por la corriente para una Fragata de la Armada Colombiana en aguas profundas y poco profundas mediante la aplicación de CFD, para estimar la potencia de tiro requerida en las maniobras de asistencia en muelle. El estudio muestra el proceso de simulación de los coeficientes de arrastre de la corriente del buque mediante el método de simulaciones CFD que se realiza mediante el paquete de software STAR-CCM+. Se investiga el modelo a escala de CFD del buque Fragata clase Almirante Padilla. Los resultados muestran el coeficiente de arrastre de la corriente del buque calculado, considerando una velocidad de la corriente de 1 nudo con un ángulo de incidencia de 90° para el buque a escala real. La configuración del modelo de la presente simulación se basa en el procedimiento recomendado y publicado por Lloyds Register OCIMF y en el manual UFC para la estimación del coeficiente de arrastre de corriente.

Este documento de investigación se presenta como un análisis del comportamiento histórico de compras en los proyectos de reparación y mantenimiento en la Corporación de Ciencia y Tecnología para el Desarrollo de la Industria Naval, Marítima y Fluvial – COTECMAR, más específicamente para los ejecutados en la Planta de Bocagrande. El anterior análisis, se centra en la búsqueda de aspectos que reduzcan la brecha de incertidumbre en las compras, mediante estrategias que faciliten la planeación de las compras. El modelo de investigación está basado en el análisis histórico de las compras por medio de la clasificación de los grupos y productos adquiridos en el periodo de 2015 hasta el 2020 teniendo en cuenta la clasificación ABC-XYZ, la matriz de Kraljic y los niveles de criticidad de los productos. La investigación presenta conclusiones y recomendaciones acordes a los resultados obtenidos a partir de la clasificación y selección de los materiales o productos más relevantes dentro del grupo de compras, escogidos siguiendo la ley de Pareto. Teniendo en cuenta que la línea de negocio de reparación y mantenimiento es un mercado que presenta alta incertidumbre y variabilidad, se requiere una adecuada planeación que permitan mejorar la competitividad de los servicios prestados frente a los astilleros regionales, como muestra de la efectividad de las capacidades desarrolladas por la industria astillera colombiana.

The naval industry has integrated the generation of energy through nuclear processes, due to the large amount of energy that is produced in these processes, for example, the ship NS OTTO HAHN, which used a propulsion plant with energy generated by a reactor of pressurized water (PWR), which operated under a nuclear fission process. Also, other examples are military ships and icebreakers. In order to know the energy contribution of this type of nuclear propulsion plants, this work carries out a multiphysics analysis of a PWR reactor, considering a turbulent behavior for the fluid that comes into contact with the uranium rods. Finally, the results of the fluid velocity fields along the fuel elements and the outlet nozzles are presented, as well as the temperature fields inside the reactor.

Warning about global warming and the noxious effects of pollution, international institutions already settled drastic reductions in emissions that endanger the atmosphere. These challenges apply as much to the inland navigation industry and the coastal fleet as the ocean ships. Shipping companies are implementing new technologies to go toward the environmental goals. There is obviously a large panel of solutions. None of the solutions is a panacea and the stakeholders must make their choice depending on the type of vessel and the constraints of the area of operation, considering the related regulations to come, if not already in force. As a leading classification society, Bureau Veritas is committed to developing new rules and guidelines to keep shipping safe as it develops these innovative new green projects.

Colombia's hydrographic wealth is of great importance for the development of the economic sectors throughout the country, and together with neighboring countries such as Peru and Brazil, different needs arising from the difficult access to their more remote populations are shared. This is why, humanitarian missions are carried out through the ships of the Colombian Navy (ARC), which are at the service of the most remote civilian populations, providing, for example, response to disaster situations or covering logistics support. However, in the framework of these operations, problems have arisen due to the absence of having adequate vessels for navigation in shallow waters. To combat the problem, the ARC and the Administrative Department of Science, Technology and Innovation (MINCIENCIAS) have designated resources for Science and Technology Corporation for Naval, Maritime and Riverine Industry Development (COTECMAR) and Colombian Naval Academy (ENAP) to carry out research for the design of a new prototype vessel called BALC-L (Light Boat Logistic Support Vessel) that will meet the needs of logistics and disaster response. This paper focuses on studying and analyzing the behavior of the BALC-L ship in shallow waters, coastal areas and deep-water operations by means of numerical simulation, in order to know its movements and operational limitations under these conditions. This research presents a theoretical introduction, numerical simulation results and the validation of the data obtained from maneuverability and behavior at sea.

Inland navigation in shallow waters with partially submerged objects and riparian vegetation might represent severe restrictions to patrolling operations of the Colombian Navy. Consequently, there is a need for a riverine combat and reconnaissance boat with the ability to operate in 0.4 m depth shallow waters and which structural arrangement is to be designed according to maritime classification societies and operational requirements of the navy. The aim of this work is to explain and to validate the 20 knots, 3.8 tons of displacement, 8.6 m length, 2.6 m beam and 0.35 m draft boat scantling by guidelines of the classification societies and hence, improving and validating by direct analysis the hull structural arrangement.

This paper takes a 2021 Argentine case to show the atmospheric and economic impacts of using LNG fueled dredgers in the second largest worldwide operation of its kind about to start in Rio de la Plata. From the emissions point of view, LNG (Liquified Natural Gas) would reduce 23%, mainly those (NOx, SOx and PM) affecting the coastal population health. The use of BioLNG would reduce 99% (60,000 Tons/yr), including as well the planetary impact of CO2 . The economic impact is estimated in savings of 14% of Dredging Cost: 665 Million Dollars (MMUsd), over the 15 years of operation. The origin of these savings is 48% Operational (reduced fuel cost) and 52% external cost mainly due to the reduced impact in Public Health Budget.

In the naval design process, there is still no consensus on the use of 3D CAD (Computer Aided Design) systems in the early stages of design. However, the integration capability of different modules is currently making their incorporation in the initial stages more appealing. The objective of this paper is to study the early stages of design as part of the whole process and to demonstrate the convenience of using a single 3D tool during the whole project. Therefore, its impact on the whole design process will be analysed by considering the basic and early design capabilities of current CAD systems, reviewing how the main naval architecture and marine engineering demands match the features and what is the solution provided by the CAD for each case. The methodology presented offers advantages from a technical, economic and time point of view.
