There is currently a growing concern in the shipping industry about energy consumption and environmental impacts. According to the International Maritime Organization's (IMO) energy efficiency guidelines, today's ships must have an energy efficiency management plan to reduce the CO2 emission and other pollutants. In this article, a bibliographic review of methodologies for the optimization of energy consumption on ships is carried out, starting from the identification of sources of energy losses, to the implementation of technical and operational measures that contribute to their improvement, making a qualitative evaluation of the identified methodologies. Sources of energy losses associated with equipment and auxiliary systems are analyzed, as well as opportunities for improvement in the use of electrical energy through the implementation of intelligent energy management systems, high efficiency motors, and lighting. The technical and operational energy efficiency measures described above demonstrate the importance of their implementation from the early stages of the ship's electrical design, as well as monitoring energy consumption during its life cycle, to improve energy efficiency on board.

Environmental logistics in Colombian river areas requires solutions that allow economic development based on tourism, without ecological degradation. Therefore, this paper shows the most relevant aspects of the project and preliminary design of a Pontoon-type vessel with a catamaran hull of 8 meters in length with enough power to reach a speed of 5 knots (85%MCR) and built in aluminum, which will also have electric propulsion based on a hydrogen fuel cell, and using renewable energies such as solar panels on the roof and a wind turbine. One of its main characteristics is that it will be a pollution-free ship and its classification will be done following the regulations of the Bureau Veritas, and all those national and international regulations that are applicable. Due to the problems generated by the daily use of the different means river transportation, which undoubtedly, could generate an irreversible affectation to the environment and a considerable loss of biodiversity in aquatic ecosystems, which worsens over time, this prototype design might be presented to national shipbuilding, as a possibility for designing eco-friendly tourist vessels for the country's river areas, as an example for future constructions that are expected with the rise of tourism in the country.

Cavitation is an unwanted phenomenon that has been present for more than 50 years in any ship propulsion system. Despite the great technological advances with the use of advanced simulation tools (CFD's), and new technology, we are still far from being able to eliminate it from propellers due to its own operating principle. This phenomenon will continue to occur under certain conditions of operation of the propulsion system of ships. The consequences of this phenomenon are well known to the Navies, shipowners and naval engineers: reduction of the service life of the propeller and sometimes of the rudder and hull too, reduction of propulsive efficiency, a significant increase in vibrations and noise on board and, consequently, a reduction in comfort conditions and stealth capacity, together with noise pollution with negative effects on the oceans and marine fauna. This issue has been on the table at the IMO since 2008, currently working on updating MEPC.1/Circ.833. For this purpose, a working group of more than 120 experts from 40 entities (countries and organizations) from all over the world has been created, being TSI one of its most involved members. After more than 5 years of research, TSI has developed the first non-intrusive system capable of automatically and continuously detect this phenomenon and quantify its intensity, with sufficient precision to provide valuable information for its control. By having a visible and real time indicator of this phenomenon, we can act and reduce the negative effects of cavitation and control the acoustic signature of our vessel at all times.

The shipping industry is moving towards quickly decarbonizing its assets. There is also a growing demand for new urban transportation (passengers, building materials, and equipment) with zero-emission propulsion. Zero-emission propulsion is available today for sustainable transport. The common size of inland navigation vessels offers the opportunity to implement innovative technologies earlier than seagoing ships. There is clearly a wide range of solutions available, with their own set of pros and cons. Batteries and fuel cells are part of a growing list of solutions to carbon-neutral or zero-emissions shipping. They become a strong choice and can be successfully combined with alternative fuels. As a result, electric and hybrid vessels are currently among the most important developments in the inland navigation sector. Bureau Veritas, as one of the major classification societies, proposes a brief review of state-of-the-art electrical solutions, considering available technologies, safety constraints and operational challenges, bringing to light its experience in electrical vessels, both in new constructions and conversions as well as in vessels in service. Although many parameters must be considered, the conclusion confirms that there are electrical solutions already suitable for a range of vessels and it is also possible to pencil the near future in association with new infrastructure and supply chain.

Navy vessels are relative long and slender ships which must withstand, during their extensive operational life, cyclic loads produced by the seaway. Fatigue is, hence, for those vessels a dominant parameter in the structural ship design and on their operation. Due to the arising complexity of fatigue assessments, an in-house tool is developed to perform automatized spectral fatigue analysis. Tool is called SEAFALT and stands for Long-Term Spectral Fatigue Analysis. This article described the calculation process of SEAFALT, together with results of a case of study. SEAFALT controls automatically the coupling process of the hydrodynamic load calculated on each sea scenario (via ANSYS AQWA), with its correspondent Finite-Element (FE) structural response (via ANSYS MAPDL). SEAFALT calculates: the expected long-term fatigue damage on each node of the FE-model and the minimum required FAT-class.

Subsequently, an approximation to the requirements to carry it out in an adequate and sustainable manner are stated, by understanding the concepts of the executive level that will help strategic alignment and the application of tools to achieve it, and then explain how to design and execute a Digital Transformation Strategy in any organization. Finally, a model to create a sustainable Digital Naval Industry is offered, leveraged by Industry 4.0 technologies, presenting mechanisms such as the creation of a national and regional naval cluster, which allows free exchange of data and open information in real time, whose enabler will be the Unified NameSpace (UNS).

The transportation sector's significant contribution to greenhouse gas (GHG) emissions, primarily through fossil fuel consumption by motorized vehicles, remains a critical concern. In this industry, maritime transportation independently contributes to 2.89% of total global greenhouse gas emissions, displaying a persistent upward trend even in the face of enhanced efficiency measures implemented in port facilities and vessel operations. In response to this urgent concern, nations and international organizations have been formulating approaches aimed at mitigating greenhouse gas emissions in this transportation sector, encompassing the implementation of economic incentives. This article presents the findings of an exploratory-descriptive research endeavor, which aims to identify incentive policies implemented across various countries to expedite the adoption of electromobility in maritime and river transportation, thereby reducing GHG emissions from vessels. Data was gathered from authorized government websites, various organizations, maritime and river transport companies, and port authorities in each respective nation. Furthermore, this study classifies the incentives according to their methodologies and conducts a comparative analysis with the existing landscape in Colombia regarding the adoption of economic incentives for electrifying river transportation within the country. Through this analysis, some insights and recommendations can be derived to promote sustainable and environmentally-friendly practices in Colombia's river and maritime transportation sectors.

The goal of this study is to analyze the hydrodynamic behavior of a Floating Wind Platform (FOWT) under regular wave conditions. The analysis considers three degrees of freedom: Heave, Pitch and Surge. The study was car-ried out using a CFD (Computational Fluid Dynamics) tool, based on the Navier-Stokes equations and the Finite Volume Method, and results were compared against experimental tests performed at the Wave/Towing Tank at Universidad Austral de Chile (CEH-UACh). For this analysis, a generic scales semi-submersible platform was used under different regular wave conditions, obtain-ing wave height data at different points of the control volume and translation and rotation movements to obtain the RAO's (Response Amplitude Operator) in each of the considered degrees of freedom. For the CFD simulations, commercial software STAR CCM+ was used, where the flow characteristics were defined through Volume of Fluid (VOF) and their respective boundary conditions. Final-ly, the results of both methodologies were compared, showing an adequate de-gree of correlation between them.
