Abstract
In this article, a general approach is made to the positive impact that the recovery of kinetic energy by means of bow thrusters in precautionary maneuvers and approach with high inertia and in the presence of wind has on the carbon footprint of a ship. With the pre-design of this energy collector, the power/speed and thrust/speed graphs are generated for a fluid vein of seawater, obtaining values with them of reduction of consumption and CO2. With the beginning of the first hydrodynamic tests on the CFD in a pipe, a basic prototype of this jet propeller is configured, like a pumped/turbined reversible hydroelectric plant, with the aim of continuing in the future different maneuvers that allow testing the hull of the ship in the presence of wind seeking to increase energy efficiency.
