nologies to increase energy efficiency and reduce ship fuel consumption. Several measures have been identified, or even applied, with the potential to achieve substantial fuel consumption and emission reductions, like slow-steaming, bio-fuels, and alternative propulsion technologies. Slow steaming has been already analysed to a great extent,...

About 80% of the total pollution from ships is caused by operational oil discharges into the sea, often made deliberately and in violation of international rules; the main reasons can be due to cost savings or lack of adequate facilities in ports to receive waste oils. Therefore, reducing waste oil discharges is crucial for a proper protection...

The paper presents an experimental analysis of the trim influence on an existing and operating ship, to assess possible fuel consumption reductions. The investigation is based on model tests performed at the towing tank of Genoa University, where the trim influence on the hydrodynamic resistances of a high-speed vessel and a slower mini-cruiser...
