Conceptual design of a Bay Tug powered by liquefied natural gas (GNL), as a strategy for the Naval energy transition

Since the Industrial Revolution, fossil fuels have been the fundamental basis of human progress, driving economic growth and industrial expansion on a global scale. For more than two centuries, coal, oil and natural gas have been the energy pillars that have powered our societies, providing the energy needed to light our cities, power our machines and move our vehicles, among many other applications. However, this extraordinary development has not been without adverse consequences and significant environmental impacts. In this context of growing awareness of the devastating impacts of fossil fuels on the environment and the urgent need to move towards cleaner and more sustainable energy sources, Liquefied Natural Gas (LNG) emerges as a promising alternative for the global energy transition. It is there where the National Navy requires the implementation of new technologies as environmentally sustainable, efficient and effective alternatives in the fulfilment of the mission. This scientific paper presents the conceptual design of an LNG-powered bay tug as a logistic support vessel for the National Navy units as a milestone in the naval energy transition.
