Seminario del Grupo de Innovación Educativa UPM en Computación y Mecánica de Fluidos (GIE CFD). Sustainable Slow Steaming for Low Carbon Shipping, STARSHIP Nastia Degiuli, Ivana Martić, Marta Pedišić Buča Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb Slow steaming has become a widely adopted strategy for commercial vessels to reduce fuel consumption and, consequently, operating costs. By reducing ship speed, this approach helps meet the International Maritime Organization's (IMO) requirements for reducing Greenhouse Gas (GHG) emissions. Initially introduced by Maersk Line in container shipping, slow steaming has since been extended to other ship types, including tankers and bulk carriers. Tankers and bulk carriers often operate in ballast conditions for almost half of their voyages. This significantly alters the shape of the underwater hull and its hydrodynamic characteristics, yet this change is seldom considered in operational analyses. With the growing trend toward slow steaming, ships are now operating under conditions quite different from those for which they were originally designed and optimized. Operating in off-design conditions can lead to several performance issues, such as changes in propulsion and propeller efficiency, changes in the level of vibration, the loss of turbocharger efficiency and the loss of heat recovery systems efficiency. Therefore, it is crucial to assess the overall performance of ships under off-design conditions. This presentation will address three key areas affected by slow steaming: changes in propulsion efficiency, alterations in main engine operating conditions, and changes in the level of vibration of the line shaft.
