Conceptual and practical ship design

Paper

In modern versions of the Directive 2009/45/EC and in some rules of classification societies, for example Registro Italiano Navale, options for the designation of the navigation area for passenger ships are proposed.
Fast ferries carry not only Ro-Ro cargo, but also a large number of passengers and therefore belong to the type of passenger ships. Considering the high speed of these vessels,...

Experimental hydrodynamics

Paper

Reducing fuel consumption and carbon emissions are two of the main concerns of the maritime industry. Among the available energy-saving devices or solutions, one of the most promising is air lubrication which has been extensively studied in the last decades, especially for the drag reduction on displacement hulls.
Compared to displacement hulls, the planing and semi-planing hulls have...

75. Numerical and Physical Modeling of Ship Impacts on Fenders

Experimental hydrodynamics

Paper

The increase in the size and mass of ships reduced transportation costs but, it created new problems associated with operational aspects of large ships. For instance, further development and testing is required to improve the berthing process of large ships under various environmental conditions. Numerical models properly developed, validated, and calibrated are a valuable tool in the design...
